I have the following method in C#:
private string adjustColumnValueLength(String value, int maxLength, PaintEventArgs e)
{
// Set up our string font
System.Drawing.Font printFontText = new System.Drawing.Font("Arial", 12, System.Drawing.FontStyle.Regular);
SizeF stringSize = new SizeF();
string newValue = value;
// Loop until the string fits the size we need
for (int x = value.Length; x >= 0; x--)
{
// Measure the string
newValue = value.Substring(0, x);
stringSize = e.Graphics.MeasureString(newValue, printFontText);
Size roundedSize = Size.Round(stringSize);
if (Int32.Parse(roundedSize.ToString()) <= maxLength)
{
return newValue;
}
}
return newValue;
}
I am calling this from within another method to get the length of a string to match the width in pixels I have to display it, however I have NO idea how I am supposed to pass in the PaintEventArgs. I've tried using System.Windows.Forms.PaintEventArgs but that does not work.
How can this be accomplished?

Complete code provided above, I'm trying to call the adjustColumnValueLength from within the ticketData method so that I can substring the value that is being printed to only the width I have available for that column.
You should only call that method from a Paint event handler. I guess you have something in your code like:
private void Control_Paint(object sender, PainEventArgs e) { ... }
You should call your method from there (and nowhere else!):
private void Control_Paint(object sender, PainEventArgs e)
{
adjustColumnValueLength("value", 10, e);
}
If you don't have that, create a event handler:
this.Control.Paint += Control_Paint;
Also read: Custom Control Painting and Rendering.

I want to change color the given search text in the DataGridView but the data is in Arabic. I have tried CellPainting event to find the bounds of the search text and draw FillRectangle, but I want to change color not highlight for search text.

Note that AllIndexesOf is an extension method for finding all the occurrences of a particular string in a given long string, which I got from this post.
public static IEnumerable<int> AllIndexesOf(this string sourceString, string subString)

Hope this helps.
I have a working code, on both the target machine, and my own machine. However, my machine is a W10, and the target is a W7. The code below should draw 5 barcodes on the right half of the page, however, when I use it on the target machine, one of two scenarios happen, depending on how I change the code. If I make the width of the barcode too big, it will go beyond the edge of the page and it will not be readable. If I make the width slightly too small, it resizes the whole barcode, and it becomes to small, again unreadable. I assume that this is a problem with the print drivers in which, they are different for both W10 and W7 (I used the same printer on both machines, same settings as well).
Is there a problem with my code and how do I change it?

I have a grid view and I want to print it.
This is my code:

int z = 0;
StringFormat str = new StringFormat();
str.Alignment = StringAlignment.Near;
str.LineAlignment = StringAlignment.Center;
str.Trimming = StringTrimming.EllipsisCharacter;
int width = 500 / (GridView.Columns.Count - 2);
int realwidth = 100;
int height = 40;
int realheight = 100;
for (z = 0; z < GridView.Columns.Count - 1; z++)
{
e.Graphics.FillRectangle(Brushes.AliceBlue, realwidth, realheight, width, height);
e.Graphics.DrawRectangle(Pens.Black, realwidth, realheight, width, height);
e.Graphics.DrawString(GridView.Columns[z].HeaderText, GridView.Font, Brushes.Black, realwidth, realheight);
realwidth = realwidth + width;
}
z = 0;
realheight = realheight + height;
while (rowCounter < GridView.Rows.Count)
{
realwidth = 100;
e.Graphics.FillRectangle(Brushes.AliceBlue, realwidth, realheight, width, height);
e.Graphics.DrawRectangle(Pens.Black, realwidth, realheight, width, height);
e.Graphics.DrawString(GridView.Rows[rowCounter].Cells[0].Value.ToString(), GridView.Font, Brushes.Black, realwidth, realheight);
realwidth = realwidth + width;
}
printDialog1.Document = printDocument1;
printDialog1.ShowDialog();
}
and when the use click on the printing button, I do this:
DialogResult result = printDialog1.ShowDialog();
if (result == DialogResult.OK)
{
this.printDocument1.Print();
}
plus in the construction of the form, I initialze the printing variables like this:
this.printDocument1 = new System.Drawing.Printing.PrintDocument();
this.printDialog1 = new System.Windows.Forms.PrintDialog();
my problem that when I click print, I got empty page though the grid view has more than 320 rows
Update 1
I am following this tutorial http://code.msdn.microsoft.com/windowsdesktop/CSWinFormPrintDataGridView-75864c45
Update 2
The grid view variable is GridView
The code is straightforward I guess
Update 3
I added
++rowCounter;
realheight = realheight + height;
ad the end of the while loop and still the same result
Your code as posted has at least three problems:
In your rows loop you don't advance the rowcounter, which will result in an endless loop.
You also don't advance your realheight variable, which will in result in overprinting all lines
since none of this happens your printDocument1_PrintPage event isn't called; you have probably only copied the code from the example and not actually hooked it up with the printDocument1.
Add to the loop's end:
rowCounter++;
realheight += height;
and in the constructor:
this.printDocument1.PrintPage += this.printDocument1_PrintPage;
Fixing these problems should at least print out something...
My problem is that is that my code prints the images overlapping each other. I do not know how to change the x and y positions. The printer should print 3 images per row and then move to the next row.

I have observed the code and found the issue.. in panel1_print u are not incrementing the values properly..
I have made the required changes now u will get the 4 bar in a line and 5th one in another line - check the attached image.
just replace ur panel1_Paint with this new code thats it you can find the changes..

..

You Should do it with the help of a DataGridView (That Contains Images in a Column).
The Images Will Then Print in each new row or column (by modifying as your desire)
The Following Class will do your work by passing it the whole DataGridView And Header in its constructor.

Your position variables are being declared inside the loop, meaning that they are reset for each pass through the loop. Keep position variables for X and Y outside of the loop over serial and adjust it for the total width (and height, if you start a new row of barcodes) of each barcode.
I want to print one tall (long) image in many pages. So in every page, I take a suitable part from the image and I draw it in the page.
the problem is that I have got the image shrunk (its shape is compressed) in the page,so I added an scale that its value is 1500 .
I think that I can solve the problem if I knew the height of the page (e.Graphics) in pixels.
to convert Inches to Pixel, Do I have to multiply by (e.Graphics.DpiX = 600) or multiply by 96 .
void printdocument_PrintPage(object sender, PrintPageEventArgs e)
{
if (pageImage == null)
return;
e.Graphics.PageUnit = GraphicsUnit.Pixel;
e.Graphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
e.Graphics.PixelOffsetMode = PixelOffsetMode.HighQuality;
float a = (e.MarginBounds.Width / 100) * e.Graphics.DpiX;
float b = ((e.MarginBounds.Height / 100) * e.Graphics.DpiY);
int scale = 1500;
scale = 0; //try to comment this
RectangleF srcRect = new RectangleF(0, startY, pageImage.Width, b - scale);
RectangleF destRect = new RectangleF(0, 0, a, b);
e.Graphics.DrawImage(pageImage, destRect, srcRect, GraphicsUnit.Pixel);
startY = Convert.ToInt32(startY + b - scale);
e.HasMorePages = (startY < pageImage.Height);
}
could you please make it works correctly.
you can download the source code from (here).
thanks in advanced.
I tried to complete your task.
Here you go. Hope it helps.
This method prints the image on several pages (or one if image is small).

This method prints every picture in the List in the needed dimensions (A4 size):
private void PrintDocument_PrintPage(object sender, PrintPageEventArgs e)

e.PageBounds.Y);
// increment page index
pageIndex++;
// indicate whether there are more pages or not
e.HasMorePages = (pageIndex < list.Count);
}
This method crops the image and returns every part of the image:
private static Image cropImage(Image img, Rectangle cropArea)
{
Bitmap bmpImage = new Bitmap(img);
Bitmap bmpCrop = bmpImage.Clone(cropArea, System.Drawing.Imaging.PixelFormat.DontCare);
return (Image)(bmpCrop);
}
The Image gets loaded from the PictureBox, so make sure the image is loaded. (No exception handling yet).
