[Solved] UserControl LoadTemplate() button click event not firing

Hi,

I'm trying to load a UserControl in a RadWindow. It gets displayed but the button click events do not get fired.

When doing the exact same thing with a RadDock, the button click event in the UserControl gets call as expected. Here is the code used to load the UserControl (largely inspired from this thread).

Can you tell me what is wrong ? Why is the Button click event not callled with the RadWindow, but called with the RadDock ?

Thanks,

Dominic.

A Problem and a Question with the inline edit RadGrid Demo

I'm working with the demo found here: http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/editondblclick/defaultcs.aspx#qsf-demo-source

My question is why is the javascript commented out in the code on the demo page?

My problem is that when I try to implement my own inline edit, I get the following error at runtime: CS0103: The name 'rGridInductions' does not exist in the current context. I thought that maybe it had something to do with the fact that i'm using nested grids but i just don't know. Here is the general layout that I have going for the grids. I only need inline editing for rGridInductions:

<-- Javascript RadCodeBlock is up at the top --> 



<

telerik:RadGrid ID="rGrid_Project" runat="server" ...>

.

<telerik:RadMultiPage ID="rMulti_Schedule" Runat="server">

<telerik:RadPageView ID="rPage_Notes" runat="server" Selected="True">

<telerik:RadGrid ID="rGrid_Notes" runat="server" CellSpacing="0" ...>

.

</telerik:RadGrid>

</telerik:RadPageView>

<telerik:RadPageView ID = "rPage_Remarks" runat = "server">

<telerik:RadGrid ID="rGrid_Remarks" runat="server" CellSpacing="0" ...>

.

</telerik:RadGrid>

</telerik:RadPageView>

<telerik:RadPageView ID = "rPage_Inductions" runat = "server">

<telerik:RadGrid ID="rGrid_Inductions_Detail" runat="server" ...>

.

</telerik:RadGrid>

</telerik:RadPageView>

<telerik:RadPageView ID = "rPage_Completions" runat = "server">

<telerik:RadGrid ID="rGrid_Completion_Details" runat="server" ...>

.

</telerik:RadGrid>

</telerik:RadPageView>

</telerik:RadMultiPage>

<Columns>

<asp:Panel ID ="pivotchart" runat ="server">

<telerik:RadGrid ID="rGrid_Inductions" runat="server"...>

.

</telerik:RadGrid>

</asp:Panel>

</Columns>

</telerik:RadGrid>

Thanks for the help!

Multiple RadWindowManagers in a page

We have a situation requiring multiple managers because we have user controls with multiple windows. There is a window manager in the user control to group these windows. When these user controls are added to the same page, the page ends up with multiple window managers, one from each user control.

Are there any best practices around creating multiple RAD Window Mangers on a page? Does having multiple managers impose any penalties in performance / scale?

RadEditor displays Folders but not the files

I had the need to connect an instance of my RadEditor and RadFileManager to a file source on an FTP, and I used the sample provided on - http://www.telerik.com/community/forums/aspnet-ajax/file-explorer/how-to-use-the-ftp-connection.aspx

The RadFileManager works flawlessly, however the RadEditor shows the folders and sub folders, but does not show the files. Note that the editor still manages to upload a file, however still doesn't show it.

My behind code:

protected void Page_Load(object sender, EventArgs e)

{

  string[] paths = new string[] { "/Files" };

txtContentEN.DocumentManager.ContentProviderTypeName = typeof(FtpContentProvider).AssemblyQualifiedName;

txtContentEN.DocumentManager.ViewPaths = paths;

txtContentEN.DocumentManager.DeletePaths = paths;

  txtContentEN.DocumentManager.UploadPaths = paths;

}

I tried adding the line below, but still no luck.

txtContentEN.DocumentManager.SearchPatterns = new string[] { "*.docx", "*.doc", "*.rtf", "*.txt", "*.pdf", "*.xls", "*.xslx", "*.ppt", "*.pptx", "*.pps" };

Problems in using Telerik Asp.Net Ajax Controls on SharePoint Visual Webpart

Hello,

I am using Telerik Asp.Net Ajax Controls on my SharePoint 2010 Visual Webpart. I want to use the RadWindow as a modal popup.
In my development environment the Radwindow works as expected. But if I deploy the solution to another SharePoint Server und click the Button which shows the RadWindow normally nothing happens and the Popup doesn't appear.

I havn't got any entries in my web-config for using the telerik controls. Furthermore i'm using a RadAjaxManager.

Do you have any ideas why it does not work on the server? Do i need some entries in web.config or do i have to make some settings to enable Postbacks?
I havn't got any ideas anymore. The strange thing is that it works in my dev environment - without any special settings - but not in the test environment.

I hope you can help me.
Thank you very much.

(Sorry - this is a wrong subject but i don't know how to move it to another ;) )

[Solved] RadAjaxLoadingPanel not showing

Hi!

I have a small problem. RadAjaxLoadingPanel does not seem to display itself on an ajax update. Events on the page are triggered as configured. It is just that loading panel never shows. I have also tried disabling CSS, but to no avail.

This is my aspx code:

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

<telerik:RadAjaxManagerProxy ID="mngrProxy" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Search1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="Search1" />

<telerik:AjaxUpdatedControl ControlID="ViewMain1" LoadingPanelID="lpnlNormal" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="ViewMain1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="ViewMain1" LoadingPanelID="lpnlNormal" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<telerik:RadAjaxLoadingPanel ID="lpnlNormal" runat="server"></telerik:RadAjaxLoadingPanel>

<div id="divSearch" class="pane pane-left">

<sid:Search ID="Search1" runat="server" OnSearchStarted="Search1_SearchStarted"></sid:Search>

</div>

<div id="divView" class="pane pane-right">

<sid:ViewMain ID="ViewMain1" runat="server"></sid:ViewMain>

</div>

<div class="clear-both" />

</asp:Content>

When I click a button in Search1 control a SearchStarted event is triggered and ViewMain1 control (containing RadGrid) is updated. However, lpnlNormal, never ever shows. Search1 and ViewMain1 are custom controls.
