I am getting this error after I reset the values of the controls including RadComboBox.
Here's the scenario:

1. I have asp.net controls including dropdownlist, textbox and 2 RadComboBox
2. First RadComboBox = source depends on asp.net dropdownlist selected value
3. Second RadComboBox = source depends on First RadComboBox selected value
4. ASP.NET dropdownlist and First RadComboBox are set to autopostback=true and have selectedindexchanged events
5. Has an asp.net button "Reset" to reset/clear the values for the controls

Error occurs when I select an item on ASP.NET dropdownlist after OnClick event of reset button
Below is the error I got on our log file since when in debug mode, I just get a blank page


Notes:

• I already remove the partial postback (radajaxmanager)
• I retain the event for asp.net dropdownlist and radcombobox event but commented all codes inside it so it will just postback and no code will be executed

OnClick event has below code: (I also tried commenting the part of the 2 RadComboBox which are: ddlFailureCategory and ddlFailureSubCategory but still get error)


Kindly give an advice on how to interpret the error I got since in debug mode, I didn't get an exception.

Thanks.

The docs for this make no mention of tests for IE10.

is this an oversight in the Docs or in the Library?

Hello,

When I enter data in the Rad Text Box (after a postback operation), the entered data does not remain for the next postback. I mean... The data entered in the Text box does not remain in the viewstate. I am facing this problem only when I use Rad Text Box. This is not page specific. But this does not happen everytime. The occurrence is more often but not always.

Please let me know if you need any further information regarding this problem.

Thanks

Hi,

Is it possible to limit the resize capability of the Editor so that users may only resize it vertically rather than both vertically and horizontally? Currently we are having to disable all Resize capabilities to prevent the users from breaking the page.

Hope you can help

Hi

We just updated to the most recent 2013 Q1 upgrade of ASP.NET tools, and all of the sudden the RadDropDownLists are not working properly with the RequiredValidators,  The validators keep showing messages even though there's content on the dropdowns.  The latest browsers versions of Chrome and IE have this problem.  

Curiously, with IE version 8 this problem does not occur!

I'd appreciate any help or bug fix for this as it is a critical problem


Thanks in advance

I have a RadGrid that I am create on Page_Init. I have EnableViewState and EnableColumnsViewState both set to true. I apply a filter on the grid, the system runs the NeedDataSource and the correct records are applied. The filter value is still in the textbox. I then apply a second filter to a different column. The system runs the NeedDataSource and records that only apply to the second filter show. The first filter is not applied and the value in the textbox of the first filter is erased. I don't believe this is the desired behaviour. What am I doing wrong?

I have a RadGrid that I am creating programmatically in the Page_Init. I have set the EnableViewState to True for both the RadGrid and the RadGrid.MasterTableView.

Once the grid displays, the user applies a filter. The radgrid is automatically re-bound. My problem is the ItemCommand is fired after the NeedDataSource. I don't believe this is the correct behaviour from what I have read. I would like to gather my filtering options before the NeedDataSource is fired.

Let me know what I am doing wrong.

Hi,

I have a problem where the DataBinding event of my RadGrid is not called after a Filter on any column. The event is only called on the very first binding of the grid or if I call a Rebind(). 

I can see that on filter, it correctly call ItemCommand -> NeedDataSource -> DataBound, but not DataBinding before DataBound.

Is that a normal behavior or this is an issue? 

Thanks.

I have a radgrid with the grid tied to one datasource and a grid attachment column tied to another one.  The purpose is to just click on the link for the column and have it open the appropriate web plug-in for that attachment.

When I debug the grid in IE 9, I get an exception thrown out of the RadScript Manager.  Line: 6
Error: Could not complete the operation due to error c00ce514. 

From what I can tell, it doesn't even hit the database for the second datasource to retrieve the image when running in IE.

When I run the same code in Firefox, everything behaves as expected.  When I have googled the error, it talks about temporarily turning off Ajax.  My gut feeling is that the Javascript code I have in place is being ignored in IE.  I have set breakpoints in that Javascript code just to make sure it is getting executed and the objects are not null / nothing. 

Any idea what could be going on?  Here is a snippet of the code...
