The control with ID 'PagingTest1_Store2' not found

[csharpdev]

Hello,

i searched the forum for a similar problem but could not find something what fits, so might
someone can point me in the right direction.

I create a new Windows with a Control like this:

        protected void btnPagingTest1_Click(object sender, DirectEventArgs e)
        {
            Window win = new Window
            {
                ID = "windowPagingTest1",
                Title = "Paging Test 1",
                Height = 600,
                Width = 800,
                Padding = 5
            };
            baseUserControl userControlPaging = (baseUserControl)LoadControl("~/Views/PagingTest1.ascx");
            userControlPaging.ID = "PagingTest1";
            win.ContentContainer.Controls.Add(userControlPaging);
            win.Render();
        }

The Control looks like this:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="PagingTest1.ascx.cs"
    Inherits="Web.Views.PagingTest1" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

                <ext:RecordField Name="Lastname" Type="String" />
            </Fields>
        </ext:JsonReader>
    </Reader>
    <BaseParams>
        <ext:Parameter Name="start" Value="0" Mode="Raw" />
        <ext:Parameter Name="limit" Value="100" Mode="Raw" />
        <ext:Parameter Name="sort" Value="" />
        <ext:Parameter Name="dir" Value="" />
    </BaseParams>
</ext:Store>
<ext:GridPanel ID="GridPanel2" runat="server" Border="false">
    <ColumnModel ID="ColumnModel2" runat="server">
        <Columns>
            <ext:Column Header="Id" DataIndex="Id" />
            <ext:Column Header="First name" DataIndex="Firstname" />
            <ext:Column Header="Last name" DataIndex="Lastname" />
        </Columns>
    </ColumnModel>
    <LoadMask ShowMask="true" />
    <BottomBar>
        <ext:PagingToolbar ID="PagingToolbar2" runat="server" PageSize="100" />
    </BottomBar>
</ext:GridPanel>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Ext.Net;

namespace Web.Views
{
    public partial class PagingTest1 : baseUserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        }
        protected void Store2_RefreshData(object sender, StoreRefreshDataEventArgs e)
        {           
        }      
    }
}

As long the <Proxy><ext:PageProxy /></Proxy> in the Store exists, I always get the error

[HttpException (0x80004005): The control with ID 'PagingTest1_Store2' not found]

Hi,

You have to recreate window control on each request

Hi,

You have to recreate window control on each request

I'm facing similar problem. I'm creating Ext.window dynamically and also loading an ASP user control inside this window.
Now, when I have loaded this window and I click on a Ext.button that is defined in the user control, Im getting an error the ext.button control with the control id is not found.


My code snippet to dynamically create a window and add to a Panel

Dim newWindow = New Ext.Net.Window()
newWindow.ID = "ClientViewSearchID"
newWindow.Icon = Icon.Hourglass
newWindow.Title = "Client View Search"
newWindow.X = 100
newWindow.Y = 100
newWindow.Height = 400
newWindow.Width = 300
newWindow.Constrain = True
newWindow.Hidden = False

'Add user control to window content
Dim uc1 As UserControl
uc1 = CType(LoadControl(FilePath.ClientViewSearch), ClientViewSearch)
uc1.ID = "UCClientViewSearch"
newWindow.ContentControls.Add(uc1)

'add window to panel.
ContentPanel.Items.Add(newWindow)

newWindow.Show()
newWindow.Render()
newWindow.UpdateContent()
-----------------------------------------------------------------------------------------------
My code snippet for User control

<br />
&nbsp;&nbsp;&nbsp;&nbsp;<ext:Button id="buttonForView" runat="server" Text="View Client" OnDirectClick="buttonForView_click" >
</ext:Button>

</p>
<br />
<ext:Button id="btnCancelSearchId" runat="server" Text="Cancel" OnDirectClick="btnCancelSearch">
</ext:Button>
<br />

Snippet for Code Behind of my user control.

Protected Sub buttonForView_click(ByVal sender As Object, ByVal e As DirectEventArgs)

'ViewClientWindow.Show()
Dim win As Window = Parent.FindControl("Window2")
win.Show()
End Sub

Protected Sub btnCancelSearch(ByVal sender As Object, ByVal e As DirectEventArgs)
Dim win As Window = Parent.FindControl("Window4")
win.Hide()
End Sub
