how to change image of imagebutton by checking value gets from database in for loop ? in asp.net

Question

I want to control the value of each row in repeater in order to change image if the value is different. My problem is that I cannot get value from repeater by trying to get of data each rows(). How can I solve it?

  for (int i = 0; i < repeater_talepler_list.Items.Count; i++)
        {
        ImageButton ib=(ImageButton)repeater_talepler_list.Controls[4].Controls[0].FindControl("islemeAlButton");

            bool res = CheckTalep(id, User_Name);
            if (res)
            {
                ib.ImageUrl = "~/images/confirm.png";
            }
        }

I guess that you can't find the ImageButton with repeater_talepler_list.Controls[4].Controls[0].FindControl("islemeAlButton").

Use FindControl on the complete RepeaterItem instead of a nested control in it:

RepeaterItem item = repeater_talepler_list.Items[i];
ImageButton ib = (ImageButton) item.FindControl("islemeAlButton");
