受保护的void GridViewStaff_RowCommand（对象发送者，GridViewCommandEventArgs e）         {             // int index = Convert.ToInt32（（（sender as LinkBut​​ton）.NamingContainer as GridViewRow）.RowIndex）;             整数索引= Convert.ToInt32（e.CommandArgument）;

        if (e.CommandName.Equals("editRecord"))
        {
            GridViewRow gvrow = GridViewStaff.Rows[index];
            txtfirstNAme.Text = HttpUtility.HtmlDecode(gvrow.Cells[3].Text).ToString();
            txtLastName.Text = HttpUtility.HtmlDecode(gvrow.Cells[7].Text);
            txtCountry.Text = HttpUtility.HtmlDecode(gvrow.Cells[4].Text);
            lblResult.Visible = false;
            System.Text.StringBuilder sb = new System.Text.StringBuilder();
            sb.Append(@"<script type='text/javascript'>");
            sb.Append("$('#editModal').modal('show');");
            sb.Append(@"</script>");
            ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "EditModalScript", sb.ToString(), false);

        }
