Hi,

I need your help.

How to pass DataKeyNames using Image Button Row from Gridview ASP.Net?

I have this error Object reference not set to an instance of an object.

My code below

protected void btn_Click(object sender, ImageClickEventArgs e)
{
    ImageButton lnkbtn = sender as ImageButton;
    GridViewRow gvrow = lnkbtn.NamingContainer as GridViewRow;
 
    if (lnkbtn != null)
    {
        foreach (GridViewRow row in gvProducts.Rows)
        {
            //New
            CheckBox chk = (CheckBox)row.FindControl("chkRow");
            string lbCode = gv.DataKeys[gvrow.RowIndex].Values[0].ToString();
 
            Response.Write(lbCode + "<br />");
        }
        this.BindGrid();
    }
}
