I need a way to be able to retrieve child controls on a <asp:Content
</asp:Content> the way I used to using findcontrol("ControlID"), when ever
Click to expand...
I've try I get nothing.

Where should I look?

thanks,

Vic
 
Hi Victor,

It's because FindControl cannot find control recursively, it only find
controls directly beneath the parent control. You can use following
function to find controls recursively:

private Control FindControlRecursive(Control root, string id)
{
if (root.ID == id)
{
return root;
}

foreach (Control c in root.Controls)
{
Control t = FindControlRecursive(c, id);
if (t != null)
{
return t;
}
}

return null;
}

Hope this helps. Please feel free to post here if anything is unclear.

Hello Victor,

How are you doing on this issue, does Walters'suggestion helps you some?

BTW, if your code will be dedicated to some particular pages with similar
control structure, you can use the ASP.NET page's output trace to lookup
the control structure of each page. The output trace contains a control
tree in which you can find the position of each server control in the
entire page control structure. You can use the @Page directive to turn on
output trace:

<%@ Page ............... Trace="true" %>

Hope this also helps.
