I have a WPF application that uses the WebBrowser control in order to print html documents.
My problem is that from time to time some of the characters are missing from the generated documents.
I tried to replace the printer and cables and I also validated the html markup here.
This is how I generate the printing:
public static class HtmlPrint
{
public static void Print(string html, string documentTitle)
{
var wb = new System.Windows.Forms.WebBrowser { DocumentText = html };
wb.DocumentCompleted += wb_DocumentCompleted;
}
private static void wb_DocumentCompleted(object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs e)
{
var wb = ((System.Windows.Forms.WebBrowser)sender);
wb.Print();
wb.Dispose();
}
}
HTML sample:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title>Items report</title>
<style type='text/css'>
html, body {
margin: 0;
padding: 0;

Any ideas on how to fix it?
UPDATE
I've tried using the System.Windows.Controls.WebBrowser as follows but it prints empty pages:
public static void Print(string html)
{
/*
html is the actual HTML data e.g.
<!DOCTYPE html>
<html lang="he-IL" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=9">
...
*/
try
{
var wb = new System.Windows.Controls.WebBrowser();
wb.LoadCompleted += Wb_LoadCompleted; //never called
wb.Loaded += Wb_Loaded; //never called
wb.NavigateToString(html);
mshtml.IHTMLDocument2 doc = wb.Document as mshtml.IHTMLDocument2;
doc.execCommand("Print", true, false);
}
catch (Exception ex)
{
//no exception raised
throw;
}
}

I have an table generated from the code-behind and have tried applying the HTML5 draggable attribute to its table cells.
TabCell.Attributes["draggable"] = "true";
The above applies the attribute successfully as I can see it in inspect element but the element doesn't drag.
Does anyone have any idea's why this may be?
I had to set draggable through JQuery on the element.
$('#myid').draggable();
Doesn't work when the attribute is applied server-side
It's not entirely clear from your question what TabCell is, but assuming it's just a clientside HTML element you want to do:
TabCell.setAttribute("draggable", "true");
You don't need JQuery. Here is some code with two tabs, both made draggable by setting the attribute as above.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<style>
.tab {
overflow: hidden;
border: 1px solid #ccc;
background-color: #f1f1f1;
}
.tab button {
background-color: inherit;
float: left;
border: none;
outline: none;
cursor: pointer;
padding: 14px 16px;
transition: 0.3s;
}
.tab button:hover {
background-color: #ddd;
}
</style>
</head>
<body>
<div class="tab">
<button id="TabCell1">Tab1 Header</button>
<button id="TabCell2">Tab2 Header</button>
</div>
<script>
window.onload = () => {
var TabCell = document.getElementById('TabCell1');
TabCell.setAttribute("draggable", "true");
var TabCell2 = document.getElementById('TabCell2');
TabCell2.setAttribute("draggable", "true");
};
</script>
</body>

I try to change text of file upload control browse button. I made file upload control visible=false and I added another textbox and button:
.aspx file:
<asp:FileUpload ID="fuUploadPhoto" runat="server" visible="false"/>
<asp:TextBox ID="tbFilePath" runat="server" />
<asp:Button ID="btnChooseFile" runat="server" Text="Choose file from disk" />
next I try to add Attribute to btnChooseFile in PageLoad in .cs. Unfortunately it doesn't work and I don't know why. Where I made a mistake?
.cs file:
protected void Page_Load(object sender, EventArgs e)
{
btnChooseFile.Attributes.Add("onclick", "document.getElementById(" + fuUploadPhoto.ClientID + ").click()");
MultiViewAddPhoto.SetActiveView(viewAddPhotoStepOne);
}
protected void btnChooseFile_Click(object sender, EventArgs e)
{
if (fuUploadPhoto.HasFile)
{
tbFilePath.Text = fuUploadPhoto.PostedFile.FileName;
string filename = Path.GetFileName(fuUploadPhoto.FileName);
string ext = Path.GetExtension(filename);
imageGuid = Guid.NewGuid();
string contenttype = String.Empty;
switch (ext)
{
case ".jpg":
contenttype = "image/jpg";
break;
case ".jpeg":
contenttype = "image/jpg";
break;
case ".png":
contenttype = "image/png";
break;
}
if (string.IsNullOrEmpty(contenttype))
{
ltrErrorMessage.Text = "Nieprawidłowy format pliku!";
}
//prawidłowy format pliku
else
{
if (fuUploadPhoto.PostedFile.ContentLength > MyConsts.DAL.SizeOfPhoto)
{
ltrErrorMessage.Text = "Plik może mieć maksymalnie "+ MyConsts.DAL.SizeOfPhoto/1024 + " Mb! Zmniejsz plik i spróbuj ponownie.";
}
//jeśli prawidłowy format i rozmiar zdjęcia
else
{
try
{
filePath = ConfigurationManager.AppSettings["FilesPath"] + "\\" + Request.QueryString["konkurs"] + "\\" + imageGuid + ext;
path = "\\" + Request.QueryString["konkurs"] + "\\" + imageGuid + ext;
//zapisujemy plik na dysk
fuUploadPhoto.SaveAs(filePath);
if (File.Exists(filePath))
{
imgInspirationPhoto.ImageUrl = filePath;
imgInspirationPhoto.Visible = true;
}
else
{
imgInspirationPhoto.Visible = false;
}
}
catch (Exception ex)
{
Logger.Error(ex.Message, LogSource, ex);
}
}
}
}
}
When you make the fileupload visible false it won't be rendered on the page i.e its not hidden but not present. hence make it display none rather than visible false.
Try this
protected void Page_Load(object sender, EventArgs e)
{
btnChooseFile.Attributes.Add("onclick", "jQuery('#" + fuUploadPhoto.ClientID + "').click();return false;");
//MultiViewAddPhoto.SetActiveView(viewAddPhotoStepOne);
}
in aspx file:
<div style="display:none;">
<asp:FileUpload ID="fuUploadPhoto" runat="server"/>
</div>
remember to add reference to jQuery library in the aspx page;
Update: Also the file is not available in the code behind until full postback This solution might help
using two js files http://the-echoplex.net/demos/upload-file/file-upload.js and http://the-echoplex.net/demos/upload-file/jelly/min.js .And add the file-upload.css file.Your sample

you can download sample project at changedfileuploadbutton text
You can't using the standard asp file upload control.
You could create your own custom control which inherits from FileUpload, there you could add custom behaviour:
public class MyFileUpload : FileUpload
{
//do stuff
}
Here I am calling the webmethod in a jquery...
If I run this code in a normal aspx page then the webmethod gets fired.. But when I use master page and put this code in child page(Default4.aspx) then web method is not being fired. I have used the colorbox jquery plugin.

I've an aspx page and I want to disable that page dynamically on a IF condition.
Here, By the word 'Disable' I mean an exactly same condition when a pop-up or a Radwindow opens and the Parent page gets disabled and the user is not able to do anything to the parent page until the pop-up gets closed.
For Ajax or Rad Controls, I can set the 'Modal' attribute of the control to true to make Parent page disabled. But what to do for my required condition.
Any suggestion would be appreciated.
You achieve the disabled effect by adding a div that covers the page using Javascript or JQuery.
var documentHeight = $(document).height();
$("body").append("<div style='z-index: 100; background: lightgray; opacity: 0.5; width: 100%; height: " + documentHeight + "px; position: absolute; left: 0; top: 0;'></div>");
The caveat is that this isn't "secure", if that's what you're after (the user could "hack" the disabling pane using Firebug or similar).
You can use ModalPopupExtender, take a look at my sample. I use this concept in all my sites and works great for all types of browsers.

My issue is that I have inherited the launch of a site which has a Twitter feed ticker placed as an absolute footer on the page. The administration has decided they do not want any retweets or #mentions included in the feed. I can see the feed is being aggregated through Atom RSS. I have attempted to just change the search terms, and the twitter URL in the C# code, and the whole site crashes.
Unfortunately, I am completely unfamiliar in C#, so my ability to modify this code is limited, at best.
The web site is constructed with includes for the header, footer, twitter bar, etc.
Furthermore, the projected launch for the site is this evening at COB, so drafting another plug-in from scratch is not really an option.
The ticker is called to the page with this (The code is missing its opening and closing comment brackets so it would display here):
com.omniupdate.div label="ticker" path="/z-omniupdate/fakes/bfeo/2012/ticker.html"
bf2012:ticker runat="server"
/com.omniupdate.div
The CSS is:

If I understand you correctly you could just check the string for the pattern you are trying to skip.
In your for each loop try something like this:
foreach (XmlNode node in entries)
{
var content = node.SelectSingleNode("at:content", ns).InnerText;
if(!content.ToLower().Contains("#somename"))
{
sb.Append(String.Format("<li><span>{2}:</span> {1}</li>", node.ChildNodes[2].Attributes["href"].Value, node.ChildNodes[3].InnerText, node.LastChild.FirstChild.InnerText.Split(' ')[0]));
}
}
have a look at regular expressions for more complicated pattern matching
