[Solved] Response.WriteFile() in RadGrid

[firatbaran]

Hello, I had a radgrid it has imagebutton some column. All columns created codebehind. Each imageButton has a file that downloadable by response.writefile() method. Method is running perfectly. But, when I click that buttons, page is not postback. therefore,  I am clicking image button, then I clicked radgrid pager button, page is postbacking, but It is not running first click.
I am Binding form in Page_Load,
 if(!Page.IsPostBack)
 {
    BindGrid()
 }

clause.
If i BindGrid every Page_Load (No, if(!Page.IsPostBack) clause), this time response.WriteFile() method not running.

I used javascript hidden field, session but they are not resolve my problem. (Because respons.WriteFile() is not  render the page.)
