I need to inherit from RadGrid and add some markup when it renders - specifically I want to add a header bar (not headers as in columns, headers as in a chunk of markup that renders across the top of the control that contains some hyperlinks for some commands related to the displayed grid contents as a whole). I want to do it through inheritance so that I can have the developers on my team easily add my derived control to dozens of pages that all need the same things hooked up so I can encapsulate it in the derived control class.

How would I go about adding some markup to the rendered markup from the derived control class? For my specific use case I want to add the markup to the stream just before RadGrid starts rendering its content. 

Conceptually, I want to turn something like this:
<div><asp:Hyperlink OnClicked="SomeHandlerInPageCodeBehindWithSameCodeOnEveryPage"/></div>
<telerik:RadGrid>...</telerik:RadGrid>

into:
<my:RadGridEx>...</my:RadGridEx>

Dear Sir,

I have a custom control that inherits from asp.net datagrid. Is there any way that I can convert/inherit from radgrid with out breaking the impletmentation as much as possible? I am fine with a 10% additional work on each page. We have numerous (100s) of pages that implements this grid so if we need to touch all the pages it will be a big overhead.

Thanking you for your earliest attention

We've included the RadScheduler in an iFrame within and MVC application.  Most everything is working fine except that the IE 10 browser, when in IE 10 compatibility mode (not exactly why it's in the mode), the calendar collapses or doesn't display correctly.   Any suggestion would be appreciated.

Hello, how can I tie the update button for the radeditor's content to a validation function?  I basically want to ensure that the user doesn't put javascript and/or links to external sites so I want to check the html of the content and throw an error message if any of these things are found.  I couldn't find a validation event and validation group for the radeditor....

I have a RadGrid which is filled with data when the user clicks a button. After this I want the user to have the option to export the grid to pdf by clicking a button on a RadToolBar, but it is not working. If I don't use ajax it works fine.

 
Can anyone see what I am doing wrong?

I apologize ahead of time since I'm likely posting this in the wrong forum. 

I'm not familiar with telerik controls and been asked to maintain some code that uses them. In this project, I have some modifications I've been making for UI performance reasons and ran into some issues.

I have one page that contains a telerik radgrid. It's meant to be standalone or used as a widget on another page.

As a standalone page, I have no problems.

On another page, I make an ajax call to the page containing the telerik radgrid and populate an HTML tag with the results. On the page, the grid appears fine. However, interacting with any of the parent pages original telerik controls results in Javascript errors likely caused by having the original page's telerik js namespace being overwritten.

Other than putting the child page into an iframe, is there another way to prevent the telerik javascript namespace conflicts of the two pages?
