Answer 1

If you just want a change your selected image url, first of all you must add CommandName your ImageButton element as a below.

<asp:ImageButton ID="imgbtncevaponayla" runat="server" CommandName="btnimgbtncevaponayla" ImageUrl="~/resimler/cevaponaybeyaz.jpg"/>

You find which button selected on your .aspx.cs file and you change that image url like that:

if (e.CommandName == "btnimgbtncevaponayla")
{
    ImageButton btn = e.CommandSource as ImageButton;
    btn.ImageUrl = "~/resimler/different.jpg";
}
