multiple images in treeview

is it possible to add multiple images in a treeview-row with different actions?

as far as I know it is only possible to add only one custom image and even that image.

the idea would be
+ [image] [image] [image] itemname
+ [image] [image] [image] itemname
etc

hope someone can help!
or is there an other tool for the job

ASP.NET or WinForms TreeView?

vb.net treeview

the only way I can think of is:
node.txt = "text of node here"
node.txt = node.txt + "<a href='#'><img scr='path-to-img'></a>"
node.txt = node.txt + "<a href='#'><img scr='path-to-img'></a>"
node.txt = node.txt + "<a href='#'><img scr='path-to-img'></a>"

OK, that looks like ASP.NET TreeView. Did that way work for you?

yes it works. but now the links are normal html links, not postback. isn't there a way to add multiple link buttons to the treeview?

When you create a LinkButton, it renders as a special anchor element, with a call to __doPostBack.

<a id="LinkButton1" href="javascript:__doPostBack('LinkButton1','')">LinkButton</a> </div>

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['form1'];
if (!theForm) {
    theForm = document.form1;
}
function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}
//]]>
</script>
 
 
<div>
 
	<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/wEWAgLGrYuuCwLM9PumD+FE4KFENnlaEGuQ4O6N7u//H6Ff" />
</div>
    <div>
      <a id="LinkButton1" href="javascript:__doPostBack('LinkButton1','')">LinkButton</a>&nbsp;</div>
  </form>
</body>
</html>

yes, but is it possible to mix strings with an imagebutton?

Dim lnk As New ImageButton()
lnk.ImageUrl = "path here"
lnk.PostBackUrl = "url here"
node.txt = "some string"
node.txt = node.txt + lnk

yes I'm aware of make a test page, and that's what I do often. the questions was if treeeview was the right tool foor the job and if so, is the solution I suggested the right thing to do. or if there is another, better, solution.
I tried to mix html and hard coded postback links as you suggested and that works fine.
problem solved!
