As the other responder said, you can't use it directly.

When you use repeater control, ids of each control inside it will be replaced by something like this - RepeaterControlID_ctSomeNo_ControlID. And this is logical because the same control id cannot be used multiple times (for multiple rows in repeater control).

Use the technique he suggested.

If you want to use asp:image button inside repeater then

You need to find out that image button using find control method.

give command name to image button, as well as command argument (as id of that image) in image button.

Use repeater Item_Command event.

and put condition

if (e.commandName == "commandName")
{
use e.commandArgument as u like.
// do code here for change image url
}
