I'm looking for a piece of code to convert an HTML file or code to an image file. I tried to do some search on google, I found a few but it only works on Windows application not web (asp.net).I'm basically trying to convert a formatted html page to an image at the server side.

I am trying to wire some fancy Javascript (PopBox) to an ImageButton control and I am getting a very strange run-time (Compilation) error.
<asp:imagebutton id="imgBtnPicture" runat="server"
class="PopBoxImageSmall"
pbshowcaption="true"
title="Click to magnify/shrink"
onclick="Pop(this,50,'PopBoxImageLarge');"
width="90%">
</asp:imagebutton>
I've looked at replacing the ImageButton web control with a simpler HTML img tag (which is what the PopBox documentation suggests). Yet, I don't know how to populate an <img> tag from the CodeBehind file. Here is a typical statement which sets the .SRC property from an ASP.Net dataset row:
Me.imgBtnPicture.Src = theRow.Item("ImageURL")
I've tried this as an alternative:
<img alt="" src=""
id="imgPicture" runat="server"class="PopBoxImageSmall" title="Click to magnify/shrink"
onclick="Pop(this,50,'PopBoxImageLarge');" width="90%"
/>
Visual Studio 2008 does not complain about this declaration above but in the codebehind file, how would I address this so I could populate the .Src attribute.
Intellisense, cannot even "see" this
Me.imgPicture.src = theUrl 'this won't compile...
I added this at the top of the codebehind but seemed to have no effect:

I have this razor code ...
Code:
<ul>
<li>
@("hello <i>world</i>")
</li>
<li>
hello <i>world</i>
</li>
</ul>
When I run it the italic attribute works on the second item, but not on the first. I'm guessing it doesn't work because it's being passed as a literal string and the html formatting is lost.
How can this be made to work?
The reason I ask is because in my project, the text for the list item is stored in a database and I want the ability to include formatting for the item at the database level.
Code:
@Html.Raw("hello <i>world</i>")
However, I am not getting the result I need, so here is a bit more code....
Code:
@helper addNodes(dcNode As DocumentContent)
@<li id=@dcNode.Id>
@dcNode.nodeTitle <--This results in "White Papers - <i>New</i>"
@Html.Raw(dcNode.nodeTitle) <--The truncates the string at the tag and results in "White Papers -"
@If dcNode.children.Count > 0 Then
@For Each childNode As DocumentContent In dcNode.children.Values
@<ul id=@dcNode.nodeTitle>@addNodes(childNode)</ul>
Next
End If
</li>
End Helper
This is a recursive helper that populates node for a jsTree and works fine, but the inline html is not working. Here is what the result looks like.
The text for each li is shown twice because I am showing it once without and once with HTML.RAW. Notice the "White Paper" item... the second text is truncate at the <i> tag.Why is this and how can I fix it?

View 1 RepliesI have an ASP.NET web forms site with a rather large menu. The HTML for the menu is dynamically generated via a method in the C# as a string. I.e., what is being returned is something like this:
<ul><li><a href='default.aspx?param=1&anotherparam=2'>LINK</a></li></ul>
Except it is a lot bigger, and the lists are nested up to 4 deep.
This is written to the page via a code block.
However, instead of returning a flat string from the method I would like to return it as formatted HTML, so when rendered it looks like this:
<ul>
<li>
<a href='default.aspx?param=1&anotherparam=2'>LINK</a>
</li>
</ul>

Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

I have a static HTML page that has the basic design layout of a website that is fully functional. I need to display some data from database inside one of the div tags. I am using ASP .net 3.5 for the dynamic display of data.
So i want to convert this html page to master page and then add a content placeholder and display dynamic data from db using a gridview within this page.
Is there any way that i can convert or reference this html page as the master page in ASP .net ?
