[Solved] Find the GridView Row in ImageButton was clicked in ASP.Net

hi

I have imagebutton in gridview and I used below code for it...

   protected void Imgstatus_Click(object sender, EventArgs e)
    {
        ImageButton Imgstatus = (GridView2.Rows[0].FindControl("Imgstatus") as ImageButton);
        Imgstatus.Visible = false;

}

it just run for first row of grid view becuse of

(GridView2.Rows[0]

I want it run for all row of gridview so instead of [0] what should I write?
