Hello,
I have a page aspx like this:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="Bouwgegevens.WebForm2" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"><title></title><style type="text/css">
.modalBackground {
background-color: #819FA2;
filter: alpha(opacity=70);
opacity: 0.7;
}
.modalPopup {
background-color: #FFFFFF;
border: 1px solid #819FA2;
padding: 6px;
max-height: 100%;
border-radius: 6px;
}
</style></head><body><form id="form1" runat="server"><ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"></ajaxToolkit:ToolkitScriptManager><div><asp:UpdatePanel ID="UpdatePanel1" runat="server"><ContentTemplate><asp:Panel ID="pnlPopUpArtikel" runat="server"><asp:Button ID="btnCancel" runat="server" Text="Cancel" /><asp:GridView ID="GrvPopup" CssClass="grvContent" runat="server" AutoGenerateColumns="False" DataKeyNames="WetTekstID"
GridLines="None" CellPadding="0" ShowHeader="False"><Columns><asp:BoundField DataField="Wet_Omschrijving" HtmlEncode="false" HeaderText="Wet_Omschrijving" ReadOnly="True" SortExpression="Wet_Omschrijving"></asp:BoundField></Columns></asp:GridView></asp:Panel><asp:Button ID="btnShowPopup" runat="server" Text="Button" OnClick="Button1_Click" /><ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender5" runat="server" TargetControlID="btnShowPopup" PopupControlID="pnlPopUpArtikel"
BackgroundCssClass="modalBackground" CancelControlID="btnCancel"></ajaxToolkit:ModalPopupExtender></ContentTemplate></asp:UpdatePanel></div></form></body></html>
and a code behind .cs
using Bouwgegevens.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Bouwgegevens
{
public partial class WebForm2 : System.Web.UI.Page
{
DBBouwgegevensEntities _context = new DBBouwgegevensEntities();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
var source = (from a in _context.tbl_WetTeksten
where a.WetTekstID == 13
select new
{
a.WetTekstID,
a.Wet_Titel,
a.Wet_Omschrijving
}).ToList();
GrvPopup.DataSource = source;
GrvPopup.DataBind();
}
}
}When thegridview is not in thepanelwithModalPopupExtender, it works. Butit does not workin this example.What am I doingwrong.
Kind regards Mark
