UpdatePanel in ContentTemplate - Unregister error

I am dynamically generating a RadWindow with an AJAX UpdatePanel added to it's ContentTemplate in my custom server control (during the control's Init event) like so:

_updatePanel = new UpdatePanel() { ID = string.Format("{0}_UpdatePanel", ID), UpdateMode = UpdatePanelUpdateMode.Conditional };
_modalWindow = new RadWindow();
_modalWindow.ID = string.Format("{0}_radWindow", ID);
_modalWindow.ContentContainer.Controls.Add(_updatePanel);

The server control with said RadWindow is also dynamically declared in a RadGrid's GridTemplateColumn. The idea is when the user edits a RadGrid record that contains a RadComboBox the user can view/edit the details of the selected RadComboBox item in a RadWindow popup. This all works fine until I attempt to hit the Save or Cancel button on the RadGrid to close edit mode.

I am aware of the following posts that describe why the error is happening but I am not sure how to go about solving this in my situation.

http://www.telerik.com/support/kb/aspnet-ajax/window/details/cannot-unregister-updatepanel-with-id-updatepanelid-since-it-was-not-registered-with-the-scriptmanager-error

http://www.telerik.com/forums/is-a-partial-postback-with-radwindow-possible

It seems the solution is to declare the RadWindow directly on the page. The problem is I am developing a server control, would it work if I got a reference to the Page and added it directly instead of to the ControlCollection of my server control?

 

Thanks!

RadWindow callback function executes before the window
I'm trying to show an alert before a page redirect (after a form submission).
I tryed every possible scenario but it seems that the callback function (wich actually performs the redirect) is always executed before the window.

As a last option I tryed
<asp:Panel ID="AjaxPanel" runat="server" defaultbutton="LoginConfirm">
    <telerik:RadScriptBlock ID="RadScriptBlock" runat="server">
        <script type="text/javascript">
            activeAjaxRequest = false;
            noPermanentLogin('sdf');
        </script>
    </telerik:RadScriptBlock>
where noPermanentLogin just:
function noPermanentLogin(args) {
    radalert('Radalert is called from the client!', 330, 180, 'Client RadAlert', alertCallBackFn(args), '');
}
function alertCallBackFn(args) {
    alert(args);
    //window.location.href = args
}

Now when I first load the page the RadWindow should open each time and upon clicking "OK" button the alert should fire.
Instead the alert fires and the window is not created because of:
Uncaught TypeError: Cannot call method 'radalert' of undefined
It seems that the radwindow object has not yet been instantiated but nonetheless the callbackfunction executes the same.. this is quite mindblowing to me...

In the real scenario I tryed several versions, whose behaviour (in all situations) is that the callbackfunction gets executed BEFORE the window is showed. In those cases btw the window is showed.
So I tryed in code behind:
Me.AjaxManager.ResponseScripts.Add("noPermanentLogin('returnUrl')")
Then I tryed
RadWindowManager.RadAlert("Testina", Nothing, Nothing, "Totolo", "window.location.href = '" & returnUrl & "'")
And finally I tryed:
RadWindowManager.RadAlert("Testina", Nothing, Nothing, "Totolo", "redirectFunction('testurl')")
(in this last case redirectFunction calls the window redirect and is in an external JS in the page).

Why the callback function is executed even before showing the radalert?
Thanks in advance for your help

Cascading DropDowns in RadGrid using BatchEdit Mode
In the RadGrid i have setup there are columns for a Vehicle Make, Model, and Style, the desired effect would be to link the selected values between the three and have any models shown reflect the make chosen, and for styles they would conditionally show based off the model chosen (data filtering achieved through sql procedures) but my problem is (i'm using batch cell by cell editing by the way) is that i am unable to retrieve the selected values from "neighbor" dropdowns i'll call them, everywhere i have looked i see that to get the GridEditableItem it can be achievedby doing control "GridEditableItem edit = (GridEditableItem)controlX" but when i do that i get "Unable to cast object of type 'PanelNamingContainer' to type 'Telerik.Web.UI.GridEditableItem'", is there any way to innately bind a selected value to a dropdown from within the edititem template client side e.g. SelectedValue='<%# Bind("Make") %>', because that too blows up with the same listed error, at face value i have three dropdowns that need to communicate their values (in a reliable manor) to eachother for purposes of filtering their respective items.

Please Advise

How to bind radcombobox inside rad grid?
Here is my grid:

                <telerik:RadGrid ID="gvWebUsers" runat="server" 
                    OnNeedDataSource="gvWebUsers_NeedDataSource" 
                    OnItemCreated="gvWebUsers_ItemCreated"
                    Skin="Gray" 
                    AutoGenerateColumns="false"
                    OnItemDataBound="gvWebUsers_ItemDataBound" 
                    AllowAutomaticUpdates="true"
                    AllowPaging="true" 
                    CssClass="SettingsGrid" 
                    Width="99.7%">
                    
                    <ClientSettings Resizing-AllowColumnResize="true" Resizing-ClipCellContentOnResize="true" />
                    
                    <MasterTableView DataKeyNames="UserID" PageSize="15" EditMode="InPlace" >
                        <PagerStyle Mode="NextPrevAndNumeric" />
                        <Columns>
                             <telerik:GridBoundColumn DataField="EmailAddress" HeaderText="<%$ Resources:English,Settings_MobilityUsers_Email %>"
                                UniqueName="EmailAddress" ReadOnly="True" />
                                
                             <telerik:GridBoundColumn DataField="FirstName" HeaderText="<%$ Resources:English,Settings_MobilityUsers_FirstName %>"
                                UniqueName="FirstName" ReadOnly="True" />
                                
                             <telerik:GridBoundColumn DataField="LastName" HeaderText="<%$ Resources:English,Settings_MobilityUsers_LastName %>"
                                UniqueName="LastName" ReadOnly="True" />
                        
                             <telerik:GridBoundColumn DataField="IsDomainUser" HeaderText="<%$ Resources:English,Settings_MobilityUsers_IsDomainUser %>"
                                UniqueName="IsDomainUser" ReadOnly="True" />
                                
                             <telerik:GridBoundColumn DataField="IsVerified" HeaderText="<%$ Resources:English,Settings_MobilityUsers_IsVerified %>"
                                UniqueName="IsVerified"  ReadOnly="True"/>
                                
                             <telerik:GridButtonColumn HeaderStyle-Width="80px" ItemStyle-Width="80px" ButtonType="LinkButton" UniqueName="BlockButton" />
                             
                             <telerik:GridButtonColumn HeaderStyle-Width="80px" ItemStyle-Width="80px" ButtonType="LinkButton" UniqueName="ChangePassButton" />

                            <telerik:GridButtonColumn HeaderStyle-Width="80px" ItemStyle-Width="80px" ButtonType="LinkButton" UniqueName="AllowUploadButton" />
                             
                             <telerik:GridButtonColumn HeaderStyle-Width="80px" ItemStyle-Width="80px" ButtonType="LinkButton" UniqueName="UnlockButton" />




                    <telerik:GridTemplateColumn HeaderText="Category" ItemStyle-Width="240px">
                        <ItemTemplate>
                            <%#DataBinder.Eval(Container.DataItem, "IsUploadAllowed")%>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadComboBox runat="server" ID="RadComboBox2" skin="Gray">
                            </telerik:RadComboBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

                    <telerik:GridEditCommandColumn FooterText="EditCommand footer" UniqueName="EditCommandColumn"
                        HeaderText="Edit" HeaderStyle-Width="100px" UpdateText="Update">
                    </telerik:GridEditCommandColumn>
                            
                            
                        </Columns>
                        
                    </MasterTableView>
                </telerik:RadGrid>



I try to bind data from server side as suggested in your posts:

    protected void gvWebUsers_ItemDataBound(object sender, GridItemEventArgs e)
    {
         if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            
            GridEditableItem editItem = (GridEditableItem)e.Item;
            RadComboBox combo = (RadComboBox)editItem.FindControl("RadComboBox2");
            combo.DataSource = GetUploadStatus();
            combo.DataTextField = "Key";
            combo.DataValueField = "Value";
            combo.DataBind();
        }
    }


But it never enters into the "if" statement (there is no GridEditableItem)
what am I doing wrong??

RadGrid group header has extra cell

I am unable to center the text in the group headers of my RadGrid. When I inspect the page I see that the header row is comprised of two <td> tags instead of one. The second <td> holds the desired text and is center-aligned, but because of the extra cell the text appears pushed over towards the right.

Here's the relevant code:

<p><telerik:RadGrid runat="server" ID="RadGridUsers" <br>                    AutoGenerateColumns="False" <br>                    ShowGroupPanel="False"<br>                    GroupingSettings-GroupContinuesFormatString=""<br>                    OnNeedDataSource="RadGridNeedDataSource"<br>                    AllowPaging="True" <br>                    OnColumnCreated="RadGridColumnCreated"<br>                    OnItemCreated="RadGridItemCreated"<br>                    EnableViewState="True"><br>                    <ClientSettings><br>                        <Scrolling UseStaticHeaders="True" ScrollHeight="100px"/><br>                    </ClientSettings><br>                    <MasterTableView AllowAutomaticUpdates="False" AllowPaging="True" PageSize="20" PagerStyle-AlwaysVisible="True" AllowSorting="True" AllowFilteringByColumn="True" Width="100%"><br>                        <GroupByExpressions><br>                            <telerik:GridGroupByExpression><br>                                <GroupByFields><br>                                    <telerik:GridGroupByField  FieldName="Department" SortOrder="Ascending"/><br>                                </GroupByFields><br>                                <SelectFields><br>                                    <telerik:GridGroupByField FieldName="Department"/><br>                                </SelectFields><br>                            </telerik:GridGroupByExpression><br>                        </GroupByExpressions><br>                        <GroupHeaderItemStyle BackColor="#99bbff" ForeColor="DarkBlue" HorizontalAlign="Center" Font-Bold="True"/><br>                        <GroupHeaderTemplate><br>                            <asp:Label runat="server" ID="Label5" Text='<%# Eval("Department")%>'/><br>                        </GroupHeaderTemplate><br>                        <SortExpressions><br>                            <telerik:GridSortExpression FieldName="LastName" SortOrder="Ascending"/><br>                        </SortExpressions></p>

 

In the ColumnCreated event I'm hiding the group splitter:

<p>Protected Sub RadGridColumnCreated(ByVal sender As Object, ByVal e As GridColumnCreatedEventArgs)<br>            If (TypeOf (e.Column) Is GridGroupSplitterColumn) Then e.Column.Visible = False<br>        End Sub</p>

 

In the ItemCreated event I'm removing the grouping controls:

<p>Protected Sub RadGridItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)<br>            If (TypeOf (e.Item) Is GridFilteringItem) Then<br>                Dim item As GridFilteringItem = e.Item<br>                If (TypeOf (e.Item) Is GridGroupHeaderItem) Then<br>                e.Item.Cells(0).Controls.Clear()<br>                e.Item.Cells(0).Width = 0<br>            End If<br>            End Sub</p>

 

The output looks something like this:

<tr class="rgGroupHeader">

<td style="width:0;"></td>

<td style="text-align:center;">Foobar</td>

</tr>

...followed by the rows of data.
