How to check if RadAjaxManager exists on the page?

I get this error because I am using a user control that is inside a page that doesn't have RadAjaxManager.
How do I check if RadAjaxManager exists on the parent page before getting the error? Some parent pages do have
RadAjaxManager, some others don't.

And if it doesn't exist, I do not want to make a request.

Thanks in advance.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error:


            Line 69:         function refreshScreen(action) {
Line 70:

<telerik:RadPanelItem>

</tr>

<tr>

Databinding when dynamically adding user controls from the client

Hi,

I have a RadTabStrip in which I allow the user to dynamically add tabs, which then make a call for the appropriate user control to populate the newly added tab.

One of the requirements is that the user can add the same tab/control multiple times.

This works good and the control is added as many times as needed.

The problem arrives when databinding.

Lets say the user adds 3 tabs, each containing the same user control, which contains a grid. Then, on the third tab, the user performs a search/databind on that third grid. The problem is that the first tab grid is the one updated/data bound, no matter what tab the search was performed on. Nothing happens on the third grid.

The user control consists of a textbox and grid, bound to an entity datasource.

How do I correlate the appropriate grid to the textbox text, which is the WHERE parameter for the entity datasource.

Thanks! If this is unclear or you need more information, please let me know.
This is using ASP.NET 4 and the latest version of the Telerik controls, downloaded from telerik.com last week.

RadTreeView, XML, only want final child nodes to trigger NodeClick event (server side) - help!

I am prototyping a new project where users will navigate a dynamically generated list of hierarchically nested assets (bound to a RadTreeView). I want the users to be able to drill down into the tree to the actual asset item in the list. On clicking the asset item:

1. I want to reload the page using the ID VALUE (not the text displayed) of the item clicked. This will load all sorts of unique info for that item. I was going to simply use querystring variables so the users can bookmark their searches. I'd like to grab the selected ID, put it in querystring, and reload the page. What's the best practice for having an ID VALUE attached to a node (in XML)? What is the best way to access it in C#?

2. I also want to persist on refresh what the user clicked, so it the selected item is active (because navigating thousands of items all over again isn't acceptable). We're dealing with a nationwide list of assets.

3. I DON'T want anything to cause a postback except the final child element in the hierarchy. How do I control what causes postback and what doesn't in a dynamically generated RadTreeView list of items?

Please provide sample code if you can. NOTE: For the prototype, I've already connected to an XML file using the .LoadContentFile() method. I'm using dummy data to get started.

Thanks much for your assistance!

External Edit form without CommandItemTemplate

Hi,

Preamble:
I've managed to successfully wire up a radgrid with an external edit form by working from the demo here:
http://demos.telerik.com/aspnet-ajax/ajax/examples/manager/dynamicajaxsettings/defaultcs.aspx?product=grid

Concerns:
However, to create the "Add New Record" and "Refresh" buttons, similar to other Edit Modes, I've had to use the CommandItemTemplate.
I used a number of other RadGrids in my application, but most of them either use inline or popup edit modes... and these buttons are generated automatically.

I have the following complaints with the CommandItemTemplate approach:
1. The text labels generated by the demo do not align with the automatically generated labels for other grids. This makes all of my Grids with CommandItemTemplate controls to "look funny". I can tweak them with CSS, but this is time consuming and difficult to maintain.

2. I have to use my own copies of the RadGrid images for the buttons to make them visually consistent with all of the other RadGrids with automatically generated Command buttons.

3. Due to the complications of the above two complaints, it becomes extremely difficult to apply new skins without also involving a significant amount of editing, tweaking, and rework to maintain consistent visual style across all RadGrids in my application.

Question:
Is there any way to wire up an external edit form without using the CommandItemTemplate to create insert and refresh buttons?

All I really need is to wire the OnClick event of the generated "Add New Record" to my custom RadGrid_OnInsertCommand() event without it trying to create an in-grid edit form or a popup edit form. All of the rest of the wireup already works (i.e. the submit button on the external edit form).
