Kindly help me to do this. Thanks in advance

What I have tried:

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{

GridView1.SelectedRow.BackColor = System.Drawing.Color.Yellow;
}

  private void ClearBackColor()
        {
            foreach (GridViewRow row1 in GridView1.Rows)
            {
                row1.BackColor = System.Drawing.Color.White;
            }
        }

        protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
        {
             ClearBackColor();
             GridView1.SelectedRow.BackColor = System.Drawing.Color.Yellow;
        }

 protected void GridView1_RowDataBound1(object sender, GridViewRowEventArgs e)
        {

            if (e.Row.RowType == DataControlRowType.DataRow)
            {
ImageButton l = (ImageButton)e.Row.FindControl("ImageButton1");
                l.Attributes.Add("OnClick", "this.originalcolor=this.style.backgroundColor;" + " this.parentNode.parentNode.style.backgroundColor='red';" +
                "if (confirm('Are you sure you want to delete this record " +
                DataBinder.Eval(e.Row.DataItem, "UKC_LEDGER_CODE") + "'))return true;else {this.parentNode.parentN
}
}
