Hi guys.

I have an ASP Repeater with an ASP:Image inside the repeater and what I am trying to do is change the image on a button click here is my code:

for (int i = 0; i < repeaterList.Controls.Count; i++)
               {
                   for (int j = 0; j < repeaterList.Controls[i].Controls.Count; j++)
                   {
                       var test = repeaterList.Controls[i].Controls[j];
                       if (test.ID != null && test.ID == "descriptionImage")
                       {
                           var test2 = (Image)test;
                           test2.ImageUrl = "~/images/down-arrow.jpg";
                           return;
                       }
                   }
               }

but the imgage does not change when the button is clicked.

Please help guys.

Thanks in advance.
