Intellisense Issue with Rad Controls in ASPX pages.

Hi,
     Intellisense doesn't seem to work in ASPX pages for Telerik controls, in our project.
          1) The assemblies(Telerik.Web.UI & Telerik.Web.Design) are added to the GAC
          2) The 'web.config' refers to the latest dll's of the same.
          3) The assembly is also registered in the ASPX page like below:

<%

@ Register Assembly="Telerik.Web.UI", Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
          4) Intellisense is working fine in the code behind files.

   But, still it doesn't seem to work in the ASPX files alone. Can you please suggest a solution to enable intellisense to show up in the ASPX pages also for Telerik controls ?

    We are using Visual Studio 2008 with SP1.

Thanks & Regards,
Karthik.

[Solved] ValidatorCalloutExtender and RadNumericTextBox issue

Hi, I hope someone can help me with the following issue - It seems like there is a problem with the javascript when using the RadNumericTextBox with a ValidatorCalloutExtender.

It seems like the problem is caused when page tries to dispose of the CalloutValidator.

To reproduce the issue, slap a simple webform together that looks something like this:

                            <telerik:RadScriptManager runat="server" ID="rsm"></telerik:RadScriptManager>         
                    <telerik:RadNumericTextBox ID="txtAmount" Runat="server"></telerik:RadNumericTextBox>         
                    <asp:RangeValidator runat="server" id="rv1" MinimumValue=0 MaximumValue=1 ControlToValidate="txtAmount" ErrorMessage="Please fix"></asp:RangeValidator>         
                    <ajaxControlToolkit:ValidatorCalloutExtender runat="Server" ID="vcerv1" TargetControlID="rv1" />         
                    <asp:Button runat="server" Text="Save" ID="btnSave"  />         
                            

Now, run it and enter an invalid value in the txtAmount textbox to get the CalloutExtender to pop up. Now press F5 - I get a "'_events' is null or not an object" javascript exception. Looking at the stack trace - this seems to stem from some cleanup method called by the browser on page unload.

Am I doing something wrong, or is this a known issue - I had a look at the existing posts in the forum and couldn't find anything about this issue.

Thank you,

Peter

Using the Panel to populate a table...?

I have a table "template" on my page, and the tbody is the XmlHttpPanel...idea was to return just the <tr>s and <td>s which make up the panel (from the webservice) seeing as the headers and footers are rather large, and really all the same (never change).

...ok so the issue I'm having is that in this context the panel renders ABOVE the table (in firefox, havent tested others yet).

<div>

<table>

<thead>

...HEADERS

</thead>

<tbody>

<telerik:RadXmlHttpPanel ID="workflowPanel" runat="server" WebMethodName="GetWorkflow" RenderMode="Block" WebMethodPath="~/Apps/RTO/Webservices/WorkflowChain.asmx" OnClientResponseEnding="onWorkflowEnding" OnClientResponseEnded="onWorkflowEnded" OnClientResponseError="onWorkflowError" EnableViewState="false" >

</telerik:RadXmlHttpPanel>

</tbody>

</table>

</div>

Why would that be?...firefox not liking the div of the panel?

using anchor tags

Using version 2008.1.515.20

I found another thread that mentioned anchor tags have been fixed in a recent version, but I'm wondering if there is any workarounds for those of us that are unable to upgrade at this time? The problem seems to stem from what the rad window adds to the querystring.

http://localhost/dialogs/popupgeneric.aspx#shipping?rwndrnd=0.8012201152955385 doesnt work, but
http://localhost/dialogs/popupgeneric.aspx#shipping does.

HeaderContextMenu - Prevent Postback and Customize Options

I have two questions regarding the HeaderContextMenu in the grid:

1) How do I prevent the menu from posting back on click? I have a client-side event handler:

<HeaderContextMenu OnClientItemClicked="grid_HeaderContextMenu_ClientItemClicked" />

In this handler, I do all the processing I need client-side. However, after that client code executes, the grid still posts back. How do I prevent this? I've tried calling set_cancel(true) on the eventArgs, but the eventArgs in this case doesn't have that method. I've also tried doing the eventArgs.get_domEvent().stopPropagation() and preventDefault() as is shown in other code elsewhere, but that doesn't work either. The postback defeats my whole purpose of doing the processing client-side.

2) How do I customize the context menu options based on the column? I have added two new options to the context menu (which I add during the OnPreRenderComplete). For most of the columns, these two new options are valid, but for one column, they are not valid and so I want to hide them for only that column. How can I do this? It doesn't matter if I do this client-side or server-side.

Thanks.

Dynamic Context Menu

Hello, I'm creating a RadScheduler context menu dynamically. I call the method to create the menu in the Page Onload event. This works great unti I switch a view. Even though in the OnLoad event I can see that the Scheduler has my custom context menu items, when I right-click, I get the default menu shown. Is this something that has a workaround?
