I have a user control that contains a RadGrid with the EditLink column,


and the onClick code is generated in the code-behind file,


but whenever I click on the EditLink hyperlink I get the Microsoft JScript runtime error: Object expected exception.

My default.aspx RadScriptManager code,




any help will be appreciated.

In firefox, pressing backspace with in a delayfiltered filter box causes a postback after the delay. in IE8 and chrome it doesn't.

Full steps
1) Go to This rad grid demo page
2) put '2' in the order id column and wait for 4 seconds. The page reloads with the new filter (no results, but it doesn't matter what the text is).
3) Click on the field so that the cursor is to the right of the text.
4) Press backspace and wait for 4 seconds.
5-firefox) grid postbacks and updates as I expect it should.
5-ie-or-chrome) grid doesn't postback. Pressing enter does the postback (almost a valid workaround).

I think it should do the post back, but most of all I think it should be consistent.

Hi all,

I've just started using the Telerik controls and I'm looking for some advice on how to achieve the requirement below.

I'd like the user to be able to choose a 'Create' option from a context menu on a tree view node.

On selecting this option, I'd like to display a Telerik Window to enable the user to create a new record. If this is too difficult, I'm happy for this to be some other UI element and I'm open to suggestion here.

On saving the record, I'd like to add the newly created item into the tree node.

1. Are there any code samples on how to open up a Window or form from a context menu item?

2. I'm trying to figure out the code that's needed to add items into the treeview and I'm following the article beneath.

http://www.telerik.com/help/aspnet-ajax/treeview-general-add-node-in-edit-mode-by-default.html

When I add the following javascript into my page, I get the following error when loading the page.



The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

I’m not sure if this is relevant but I've added a RadAjaxManager onto my page and am using the code beneath in the AddNode method.

Any help or guidance would be much appreciated.

Is it possible to open the RadGrid Popup Edit window manually? I would like to open it when clicking the update button so I can capture additional information from the user. 

I have a NestedViewTemplate within a RadGrid.  Within the NestedViewTemplate I have two other Rad-grids showing data to the parent RadGrid.  The 'select' operation on both nested RadGrid's work fine.  However, when attempting to delete a record in one of the nested RadGrid, nothing happens.  Please review the below code and advise:

I've tested with and without a master page, with and without our css file, no difference.


If I specify a width on the grid and the mastertableview, the grid isn't centered on the screen.
If I remove the width on the grid it is centered.
If I set UseStaticHeaders="False" the command template is the same width as the mastertableview and centered.
If I set UseStaticHeaders="True" the command tamplate width is 100% of the screen and the mastertableview is centered.

We've never been able to use HorizontalAlign="Center" becuase we've never seen it work as expected, so we've been wrapping out grids in a <table> to center them. 

Is there something I'm missing?

hello,

I have a radgrid with But when i tested Filtering Function, the error occurred:
 
I dont know this error, please help me fix this.
thanks,

I have some issue putting a datapager to a list box. Following below is my code

So the workaround for Upload & AJAX is to do a full postback when the appropriate button is clicked.  So I have this upload, the user browses for the file they're uploading and then click submit.  But instead of just doing a full postback, the webpage never fires any server-side events and returns a bunch of nonsense (see: attached image).

I feel like this is an AJAX response?  But it does do a full-postback it seems...and it doesn't seem to fire any of my events...

I'm trying to write a workaround for the bug in your RadTabStrip control that prevents tabs from being hidden and displayed on demand.

So instead of building the tabstrip with some tabs hidden, I now add only the tab items I want displayed initially, then use javascript to add further tab items later.

Here's a snippet of the js code...

this runs ok and adds a tab to the page, but the attribute is never set, and when I look at the page source it has never been rendered. The items rendered using server side code with the same settings work fine.

Is there something else I should be doing, or is this another bug?
