Hi Victor,
It's right that we can get: <tvns:treeview . . .><tvns:treenode
Selected="true">good</tvns:treenode></tvns:treeview> on the client side if
we use TreeView1.Nodes.Add(node). However IE Treeview control is a custom
control not a user control. So, we can not achieve the same result using
mycontrol.controls.add(newcontrol).
To workaround this issue, we can add all controls to a ArrayList. Then we
could override void Render(System.Web.UI.HtmlTextWriter writer) in
*.ascx.cs and render all controls in the ArrayList by ourselves. Something
like this:
protected override void Render(System.Web.UI.HtmlTextWriter writer)
{
. . .
StringWriter sw;
System.Web.UI.HtmlTextWriter htmltw;
sw = new StringWriter();
htmltw = new System.Web.UI.HtmlTextWriter (sw);
base.Render(htmltw);
StringBuilder temp = sw.GetStringBuilder();
temp.Append("<INPUT type="button" value="Button">");//render a button;
writer.Write(temp);
. . .
}
We can also check the source code of the TreeView(treenode.cs,
treenodetypecollection.cs, treeview.cs) to achieve this in a similar way.
//We can extract IEWebControls.exe to get all source code of IE Web
Controls.
Hope this helps.
Best regards,
Lewis

| No it does not asnwer my question.
|
| I know there has to be some way to do it because when you have like a
| treeview control and you add treenodes with the form for editing
properties
| it does write the aspx code on the page. I would like to figure that out
| because it'll be very usefull.
