Im using an HTML Image control in a DataList. The reason for this is
that I need the control to run a javascript function and if im not
mistaken, this cannot be done by using a server side ASP control.
The simple task Im trying to do is at the ItemDataBound event of the
DataList, the image control should become invisible. Here's the code:
Dim arrU As HtmlImage = CType(e.Item.FindControl("imgUp"),
HtmlImage)
arrU.Visible = False
I get a Null object exception. Apparently, the control could not be
found even if the control exists. I've used similar code to
manipulate ASP Labels that are also inside the DataList and it works.
What's wrong with my casting operation? Can I use instead an ASP
Image control and still be able to run a custom javascript function
that is declared in my client script?
Thanks for your advice.
