I found some code to add an image to an Excel-sheet with the SDK 2.0. And this part works fine. Now I want a Text Box under the Image, but I don't know how to get a TextBox in general.
Which classes do I need an what is appands what or which property?
Furthermore it would be nice if it be groupt. So that when you drag one the other is following.
The code look like this (I know it's a bit much, but I couldt cut it more):
private void addImage(Offset offset, Extents extents, string sImagePath, string description)
{
WorksheetPart worksheetPart = this.arbeitsBlatt.WorksheetPart;
DrawingsPart drawingsPart;
ImagePart imagePart;
XDrSp.WorksheetDrawing worksheetDrawing;
ImagePartType imagePartType = getImageType(sImagePath);
{
// --- use the existing DrawingPart
drawingsPart = worksheetPart.DrawingsPart;
imagePart = drawingsPart.AddImagePart(imagePartType);
drawingsPart.CreateRelationshipToPart(imagePart);
worksheetDrawing = drawingsPart.WorksheetDrawing;
}
using (FileStream fileStream = new FileStream(sImagePath, FileMode.Open))
{
imagePart.FeedData(fileStream);
}
int imageNumber = drawingsPart.ImageParts.Count<ImagePart>();
if (imageNumber == 1)
{
Drawing drawing = new Drawing();
drawing.Id = drawingsPart.GetIdOfPart(imagePart);
this.arbeitsBlatt.Append(drawing);
}
XDrSp.NonVisualDrawingProperties noVisualDrawingProps = new XDrSp.NonVisualDrawingProperties();
XDrSp.NonVisualPictureDrawingProperties noVisualPictureDrawingProps = new XDrSp.NonVisualPictureDrawingProperties();
noVisualDrawingProps.Id = new UInt32Value((uint)(1024 + imageNumber));

stretch.FillRectangle = new FillRectangle();
XDrSp.BlipFill blipFill = new XDrSp.BlipFill();
Blip blip = new Blip();
blip.Embed = drawingsPart.GetIdOfPart(imagePart);
blip.CompressionState = BlipCompressionValues.Print;
blipFill.Blip = blip;
blipFill.SourceRectangle = new SourceRectangle();
blipFill.Append(stretch);

PresetGeometry prstGeom = new PresetGeometry();
prstGeom.Preset = ShapeTypeValues.Rectangle;
prstGeom.AdjustValueList = new AdjustValueList();

sp.Append(new NoFill());
XDrSp.Picture picture = new XDrSp.Picture();

anchor.Append(picture);
anchor.Append(new XDrSp.ClientData());

I think you are new to OpenXml SDK
First of all you need to use the newest version of Open XMl SDK - Version 2.5 [Download - http://www.microsoft.com/en-us/download/details.aspx?id=30425]
Here download BOTH OpenXMLSDKV25.msi , OpenXMLSDKToolV25.msi .. Install BOTH.
Now here is the trick, OpenXML productivity tool is the one you need here. It allows you to brows an existing Excel file and break it down to CODES [watch here - https://www.youtube.com/watch?v=KSSMLR19JWA]
Now what you need to do is create an Excel sheet manually with what you want [In your case add Text Box under the Image] Then open this Excel file with productivity tool and understand the CODE . Note that you will need to understand Spreadsheet file structure to understand this CODE [ Reffer this - https://www.google.com/#q=open+xml+sdk] .. Now write your codes to meet your requirement using codes of Productivity tool
NOTE - Once you analyse the dummy Spreadsheet with Productivity tool you will understand why giving or guiding with CODE examples as an answer is not practical.
- Happy Coding-

I am using Gembox.Documents to insert an HTML file into a Word or PDF document.
Unfortunately, in the resulting Word (or pdf), the height of the contents of the rows (cells) in the table is too high and does not correspond to the original one in the HTML file and I cannot change this with the help of CSS or HTML.
Can you, please, suggest solutions to the problem?
string fileName="zzzz";
var destinationDocument = new DocumentModel();
var section = new Section(destinationDocument);
destinationDocument.Sections.Add(section);
var srcDocument = DocumentModel.Load(TempPath + fileName + ".html");
var pageSetup = srcDocument.Sections[0].PageSetup;
var destpagesPageSetup = destinationDocument.Sections[0].PageSetup;
destpagesPageSetup.Orientation = Orientation.Landscape;
destpagesPageSetup.PageWidth = 1000;
destpagesPageSetup.PageHeight = 1000;
destpagesPageSetup.RightToLeft = true;
destpagesPageSetup.PageMargins.Left = 20;
destpagesPageSetup.PageMargins.Right = 0;
destpagesPageSetup.PageMargins.Bottom = 0;
destpagesPageSetup.PageMargins.Top = 0;
destpagesPageSetup.PageMargins.Gutter = 0;
destpagesPageSetup.PageMargins.Footer = 0;
var mapping = new ImportMapping(srcDocument, destinationDocument, false);
var blocks = srcDocument.Sections[0].Blocks;
foreach (Block b in blocks)
{
//b.ParentCollection.TableFormat.DefaultCellSpacing = 1;
Block b1 = destinationDocument.Import(b, true, mapping);
section.Blocks.Add(b1);
}
var pageSetup1 = section.PageSetup;
destinationDocument.Save(TempPath + fileName + ".pdf");
thanks
This issue occurred because of the cell margins appearing from the HTML content.
After investigating that HTML, the issue was resolved, the fix is available in the current latest bugfix version:
https://www.gemboxsoftware.com/document/downloads/bugfixes.html
Or in the current latest NuGet package:

I'm sure it's something stupid I'm doing but I can't figure it out. I'm trying to write a KML from scratch. It will be inside a KMZ with a bunch of georeferenced pictures that I won't to show up as photo overlays. I can't get it to write a KML though, I find the documentation too basic to incorporate a Folder. When I pause the program and debug, it shows Kml kml as having no children, but the feature 'folder' has 42. And then the namespaces aren't showing up, and it's not writing the Kml file. Please, any help you can give me!
public void WriteKML_sharp()
{
Kml kml = new Kml();
kml.AddNamespacePrefix(KmlNamespaces.GX22Prefix, KmlNamespaces.GX22Namespace);
Folder folder = new Folder();
kml.Feature = folder;
foreach (Picture picture in _process.pictures)
{
PhotoOverlay photooverlay = new PhotoOverlay();
photooverlay.Name = picture.name + picture.extension;
photooverlay.Open = true;
photooverlay.Shape = Shape.Rectangle;
Icon icon = new Icon();
Uri uri = new Uri(Path.Combine("files", picture.name + picture.extension), UriKind.Relative);
icon.Href = uri;
photooverlay.Icon = icon;
Point point = new Point();
point.Coordinate = new Vector(picture.gpslat, picture.gpslong);
//point.Coordinate = new Vector(picture.gpslat, picture.gpslong, picture.gpsalt);
point.AltitudeMode = AltitudeMode.RelativeToGround;
photooverlay.Location = point;
ViewVolume viewvolume = new ViewVolume();
viewvolume.Top = 25;
viewvolume.Bottom = -25;
viewvolume.Left = 20;
viewvolume.Right = -20;
photooverlay.View = viewvolume;
folder.AddFeature(photooverlay);
}
KmlFile kmlfile = KmlFile.Create(kml, false);
using (var stream = System.IO.File.OpenWrite(_filename))
{
kmlfile.Save(stream);
}
}
I am not sure if this will be the reason but u can try adding a document in the KML file and assign that document as kml.Feature and Add your feature to this document using .AddFeature(folder);
It works for me that way
I am trying to achieve the following: I have a C# application which does some data processing and then outputs to a .xlsx using EPPlus. I want to add some conditional formatting to the excel and tried the following method, first I made a template blank excel with all conditional formatting rules set up and then tried dumping the data in it. The snippet below is my approach. p is an Excel package. Currently this does not work, the data is written correctly however the formatting rules that I set up are lost. I'm guessing because it basically clears everything before writing. Any help will be appreciated!
Byte[] bin = p.GetAsByteArray();
File.Copy("C:\\template.xlsx", "C:\\result.xlsx");
using (FileStream fs = File.OpenWrite("C:\\result.xlsx")) {
fs.Write(bin, 0, bin.Length);
}
Note :: I tried the following as well to avoid the whole external template situation.. check snippet below. The problem with this is that, after the .xlsx is generated and I open it, it says the file has unreadable or not displayable content and that it needs to repair it and after I do that, everything is fine and the conditional formatting has also worked. I have no clue why its doing that or how I can get rid of the error upon file opening.
string _statement = "$E1=\"3\"";
var _cond = ws.ConditionalFormatting.AddExpression(_formatRangeAddress);
_cond.Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
_cond.Style.Fill.BackgroundColor.Color = Color.LightCyan;
_cond.Formula = _statement;
Any help will be appreciated!!
The method of using fs.Write will simply overwrite the copied file with the epplus generated file since you are doing it at the byte/stream level. So that will not get you what you want. (#MatthewD was showing you this in his post).
As for applying the format itself, what you have should work but if you are getting that kind of error I suspect you are mixing epplus and non-epplus manipulation of the excel file. This is how you should be doing it roughly:
[TestMethod]
public void Conditional_Format_Test()
{
//http://stackoverflow.com/questions/31296039/conditional-formatting-using-epplus
var existingFile = new FileInfo(#"c:\temp\temp.xlsx");
if (existingFile.Exists)
existingFile.Delete();
//Throw in some data
var datatable = new DataTable("tblData");
datatable.Columns.Add(new DataColumn("Col1", typeof(int)));
datatable.Columns.Add(new DataColumn("Col2", typeof(int)));
datatable.Columns.Add(new DataColumn("Col3", typeof(int)));
for (var i = 0; i < 20; i++)
{
var row = datatable.NewRow();
row["Col1"] = i;
row["Col2"] = i * 10;
row["Col3"] = i * 100;
datatable.Rows.Add(row);
}
using (var pack = new ExcelPackage(existingFile))
{
var ws = pack.Workbook.Worksheets.Add("Content");
ws.Cells["E1"].LoadFromDataTable(datatable, true);
//Override E1
ws.Cells["E1"].Value = "3";
string _statement = "$E1=\"3\"";
var _cond = ws.ConditionalFormatting.AddExpression(new ExcelAddress(ws.Dimension.Address));
_cond.Style.Fill.PatternType = ExcelFillStyle.Solid;
_cond.Style.Fill.BackgroundColor.Color = Color.LightCyan;
_cond.Formula = _statement;
pack.SaveAs(existingFile);
}
}
To expand on #Ernie code sample, here's a working example that colors a range according to cell's value. Each cell of the range can have any of three colors depending on the cell's value (<.01, <.05, <.1).
ExcelRange rng = ws.Cells[statsTableRowStart, 10, statsTableRowStart + gud.levels.level.Count() - 1, 10];
OfficeOpenXml.ConditionalFormatting.Contracts.IExcelConditionalFormattingExpression _condp01 = ws.ConditionalFormatting.AddExpression(rng);
_condp01.Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
_condp01.Style.Fill.BackgroundColor.Color = System.Drawing.Color.OrangeRed;
_condp01.Formula = new ExcelFormulaAddress(rng.Address) + "<.01";
OfficeOpenXml.ConditionalFormatting.Contracts.IExcelConditionalFormattingExpression _condp05 = ws.ConditionalFormatting.AddExpression(rng);
_condp05.Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
_condp05.Style.Fill.BackgroundColor.Color = System.Drawing.Color.OliveDrab;
_condp05.Formula = new ExcelFormulaAddress(rng.Address) + "<.05";
OfficeOpenXml.ConditionalFormatting.Contracts.IExcelConditionalFormattingExpression _condp1 = ws.ConditionalFormatting.AddExpression(rng);
_condp1.Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
_condp1.Style.Fill.BackgroundColor.Color = System.Drawing.Color.LightCyan;
_condp1.Formula = new ExcelFormulaAddress(rng.Address) + "<.1";
I have been trying for long but no success i have an existing pdf that i wan to load to my current C# app and want to create a simpe pusbutton to it , plaese cite some working code the default directory of the pdf is "C:\abc.pdf".
I am using itextsharp, C# VS 2010
Thanks
The closest solution I can find is something like the following.
static void AddPushbuttonField(string inputFile, iTextSharp.text.Rectangle buttonPosition, string buttonName, string outputFile)
{
using (PdfStamper stamper = new PdfStamper(new PdfReader(inputFile), File.Create(outputFile)))
{
PushbuttonField buttonField = new PushbuttonField(stamper.Writer, buttonPosition, buttonName);
stamper.AddAnnotation(buttonField.Field, 1);
stamper.Close();
}
}
This came from here, but was not ranked up as a solution. The code looks good and based on my experience with itextsharp I think this will do the trick.
Source:
Adding button in a pdf file using iTextSharp
Rectangle _rect;
_rect = new Rectangle(50, 100, 100, 100);
PushbuttonField button = new PushbuttonField(writer, _rect, "button");
PdfAnnotation widget = button.Field;
button.BackgroundColor = new GrayColor(0.75f);
button.BorderColor = GrayColor.GRAYBLACK;
button.BorderWidth = 1;
button.BorderStyle = PdfBorderDictionary.STYLE_BEVELED;
button.TextColor = GrayColor.GRAYBLACK;
button.FontSize = 11;
button.Text = "Text";
button.Layout = PushbuttonField.LAYOUT_ICON_LEFT_LABEL_RIGHT;
button.ScaleIcon = PushbuttonField.SCALE_ICON_ALWAYS;
button.ProportionalIcon = true;
button.IconHorizontalAdjustment = 0;
Does anybody know how to set print area through OpenXML SDK in Excel?
I've tried using the following code:
public void XLUpdateDefinedName(string fileName, string definedName, string newRange)
{
using (SpreadsheetDocument document = SpreadsheetDocument.Open(fileName, true))
{
WorkbookPart wbPart = document.WorkbookPart;
var definedNames = wbPart.Workbook.Descendants<DefinedNames>().FirstOrDefault();
DefinedName name = definedNames.Descendants<DefinedName>().Where(m => m.Name == definedName).Single();
UInt32Value locSheetId = name.LocalSheetId;
name = null;//.Remove();
wbPart.Workbook.Save();
name = new DefinedName() { Name = definedName, LocalSheetId = locSheetId , Text = newRange}
;
wbPart.Workbook.Save();
//newDefinedName.Text = newRange;
//definedNames.Append(newDefinedName);
}
}
UPDATE:
I continue to receive an error from excel saying there is unreadable content in file with the following code.
public void XLUpdateDefinedName(string fileName, string definedName, string newRange, string sheet, UInt32Value localId)
{
using (SpreadsheetDocument document = SpreadsheetDocument.Open(fileName, true))
{
String sheetName = sheet;
string topLeft = newRange.Split(':').First();
string bottomRight = newRange.Split(':').Last();
WorkbookPart wbPart = document.WorkbookPart;
var definedNames = wbPart.Workbook.Descendants<DefinedNames>().FirstOrDefault();
var nameCollection = definedNames.Descendants<DefinedName>().Where(m => m.Text.StartsWith(sheetName));
DefinedName name = nameCollection.Count() > 0 ? nameCollection.First() : null;
UInt32Value locSheetId;
if (name != null)
{
locSheetId = name.LocalSheetId;
name.Remove();
wbPart.Workbook.Save();
}
else
{
locSheetId = localId;
}
name = new DefinedName() { Name = "_xlnm.Print_Area", LocalSheetId = locSheetId};
name.Text = String.Format("{0}!{1}:{2}", sheetName,topLeft,bottomRight);
definedNames.Append(name);
wbPart.Workbook.Save();
}}
newRange is of the form ( $A$10:$C$15 )
I've found some information about a method that seems not to be using Interop. You can try something like:
//load the work book
...
myWorkBook.Worksheets.First().PageSetup.PrintAreas.Add("A1:F40");
//save the workbook
//...
See if this helps. I haven't tried it myself yet, but I'm going to verify it.
UPDATE:
The first method seems to require an additional library. You can get it from here:
http://closedxml.codeplex.com/. I haven't used it myself, so I cannot assure you it works correctly.
Pure OpenXML solution
I've managed to change the print area by manually modifying the xlsx file contents in notepad editor.
In C# you should try to use the follwoing method (it sets printing area to A1:G19):
//first you need to get reference to your workbook, but I assume you already have this
//...
//then you can add an information about desired print area
DefinedNames definedNames = new DefinedNames();
DefinedName printAreaDefName = new DefinedName() { Name = "_xlnm.Print_Area", LocalSheetId = (UInt32Value)0U };
printAreaDefName.Text = "Worksheet1!$A$1:$G$19";
definedNames.Append(printAreaDefName);
//then you should append the created element to your workbook
//...
workbook1.Append(definedNames);
The thing you need to change is line: printAreaDefName.Text = "Worksheet1!$A$1:$G$19";.
You should change the Text value to contain information in format: [worksheet_name]![top-left corner of print area]:[bottom-right corner of print area]. It should set your print area to a rectangle with upper-left and bottom-right corners as specified.
If you want to specify print areas for different worksheets, try to add multiple DefinedName objects:
DefinedName printAreaDefName = new DefinedName() { Name = "_xlnm.Print_Area", LocalSheetId = (UInt32Value)0U };
printAreaDefName.Text = "Worksheet1!$A$1:$G$19";
definedNames.Append(printAreaDefName);
DefinedName printAreaDefName2 = new DefinedName() { Name = "_xlnm.Print_Area", LocalSheetId = (UInt32Value)1U };
printAreaDefName2.Text = "Worksheet2!$B$1:$H$23";
definedNames.Append(printAreaDefName2);
DefinedName printAreaDefName3 = new DefinedName() { Name = "_xlnm.Print_Area", LocalSheetId = (UInt32Value)2U };
printAreaDefName3.Text = "Worksheet3!$A$1:$J$10";
definedNames.Append(printAreaDefName3);
I also recommend using OpenXML SDK 2.0 Productivity Tool. It allows you to show the contents of a chosen OpenXML file, compare files, validate a file and even show a C# code that you would write in order to recreate the file programatically :).
You can download it from here:
http://www.microsoft.com/download/en/details.aspx?id=5124
UPDATE II:
I've corrected a mistake in format of the print area value string. Sorry for the confusion.
I've also took the code you posted and created a method based on it. It works correctly and after modifying the print area I can open the file in Excel without issues. The code assumes that a print range is already defined and you are now just changing it, but it can be modified to add new print range as well.
Here's the code:
private void OpenXmlFileHandling(String fileName)
{
using (SpreadsheetDocument document = SpreadsheetDocument.Open(fileName, true))
{
//some sample values
String definedName = "Worksheet3";
String topLeft = "$A$3";
String bottomRight = "$D$7";
WorkbookPart wbPart = document.WorkbookPart;
var definedNames = wbPart.Workbook.Descendants<DefinedNames>().FirstOrDefault();
var namesCollection = definedNames.Descendants<DefinedName>().Where(m => m.Text.StartsWith(definedName));
DefinedName name = namesCollection != null ? namesCollection.First() : null;
UInt32Value locSheetId;
//we assume that name is not null, because print range for this worksheet was defined in the source template file
//if name was null, we should probably just assign to locSheetId a number definedNames.Count() + 1 and not remove the name node
locSheetId = name.LocalSheetId;
name.Remove();
wbPart.Workbook.Save();
name = new DefinedName() { Name = "_xlnm.Print_Area", LocalSheetId = locSheetId, Text = String.Format("{0}!{1}:{2}", definedName, topLeft, bottomRight) };
definedNames.Append(name);
wbPart.Workbook.Save();
}
}
I put the values of worksheet name and print area range inside the method, so you can see what kind of values they should have. I hope this helps.
Let me explain my case: I have excel workbook with following sheets (T1,I1,M1). Now my requirement was based on some condition T1,I1,M1 will be copied to same excel workbook multiple times e.g. T2,I2,M2, T3,I3,M3 and so on. For me I2,M2 did not have any issues with Print area but for copied sheet T2,T3... had issue. since it had huge data. excel column goes upto "AG". So here is what i did in code
Once the new sheet is added to workbook
sheets.Append(copiedSheet);
first get the current sheet count
var count = sheets.Count();
Get the sheet count, this will be used in LocalsheetId as printarea setting.
Only for copied techical sheet the print area was not set properly. Hence need to be set correctly.
DefinedName printAreaDefName = new DefinedName() { Name = "_xlnm.Print_Area", LocalSheetId = Convert.ToUInt32(count) };
Be care full with defName.Text the format is 'T1'!$A$1:$AG$19
printAreaDefName.Text = "'" + copiedSheet.Name + "'!$A$1:$AG$22";
workbookPart.Workbook.DefinedNames.Append(printAreaDefName);
workbookPart.Workbook.Save();
There was no need for me to add new Definedname in DefinedNames collection. So I just added to workbook definedNames collection and it worked.
