How to display an icon in the gridview cell column dependent on another column

[yahshuatwo]

How can you display an icon the gridview cell column which is dependent on the text value of an adjacent column. Also, I setup the asp template,item and image controls, do i need to set the imgURL value in the asp control side? here's my code below:

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                
                Image Img1 = (Image)e.Row.FindControl("Img1");
                if (e.Row.Cells[7].Text == "Accepted")
                {
                    Img1.ImageUrl = "~/images/check.ico";
                    Img1.Visible=true;
                }
                if (e.Row.Cells[4].Text =="unack")
                {
                    Img1.ImageUrl = "~/images/warning.ico";
                    Img1.Visible = true;
                }  
            }

Oh wait a sec I think I see.
Maybe you should be doing this in the OnRowBound event instead of the RowCreated event.
