Argument Exception on closing

[Edward]

I get the following error when I am closing the form.  The only operation I have done is to assign a datatable to the grid's datasource.

Hello Edward ,

Thank you for contacting us.

I am glad to inform you that recently we released a service pack of the Q3 release. The Q3 SP1 addresses the issue. We would highly appreciate your feedback on this release.

Do not hesitate to write us if you need further assistance.

Sincerely yours,
Jack

I installed the SP1 and still receive the same error.  The error only occurs after I set the DataSource to a data table.  Normal DataGridView works fine.  I tried to set the data source back to null before disposing, but still receiving that error. 

[Jack]

Hello Edward ,

I could not reproduce this issue. Maybe it is related to the data source or other specific conditions. Could you send me your application with the related data source. I will investigate the issue and will try to find a solution for you.

Let me know, if you need further assistance.

Kind regards,
Jack

I am recieving the same exception, but only when I have the Grid on a panel that I have not viewed. It appears it has something to do with the Grid not being visible, have you found a solution?

[Jack]

Hello jdgoulden,

Thank you for the additional details on this issue.

Unfortunately, we are still unable to reproduce it. I am afraid I would need to review your application and check the sequence of events that cause the issue. We have still not found the reasons for this situation and would like to investigate it further.

Thank you in advance.

Hello,  I have the same problem. Has anyone found out how to solve this problem  in the last few weeks ?

I am using the Q1_2008 and have the same error (and stacktrace) as Edward.

If no solution exists I will try to create a small project to reproduce this error.

Hello Falk Wegener,

We're still researching the cause for the issue. A sample application would be of a great help. Most probably, the issue is related to disposing the grid and its elements in specific cases with a user control or panels which are not visible and contain RadGridView.

However we're not absolutely sure and are still working on this issue. If you send us a sample application, it will help us to fix it sooner.

Also, I would suggest to try to workaround this issue by calling the Dispose method of RadGridView when the form that contains the grid is closed (disposed).

Please try this and tell us if this solves the problem.

Hello Kiril,

Thanks for your help, disposing the radgridview(s) manually works. No more exceptions.

This Exception happens when i exit my application. although it seems only to occur in 1 possible scenario (being startup -  login - logout - login exit)  rather than all exit scenario (EG. : startup - login - exit).


I have taken the time to manually implement the IDispossable interface in each form containing either a GridView directly or a Usercontrol (containing a GridView). and commentied out the override Dispose method from the Form.Designer.cs.

I cannot send you any code due to Company policy.

Hello Y,

So far we are not able to reproduce the issue. It is also not reported yet for any subsequent releases (since Q1 2008).
Please open a support ticket and share more information about your case. Any piece of information could be helpful. We also strongly recommend you to consider upgrading to the latest version.

Issue Solved by using custom event fired at the exit method.
the event is subscribed by all forms & user controls containing a GridView.

I had to do this because implementing the IDisposable was inadequate (or i didn't use it as it should be, never executed code in the inherited Dispose()).

	//@ constructor of each form||usercontrol         Dispatcher.Instance.TearDownEvent += new Dispatcher.TearDownForms(Instance_TearDownEvent);         void Instance_TearDownEvent()
	{
	grd1.DataSource = null;
	grd2.DataSource = null;
	grd3.DataSource = null;
	grd1.Dispose();
	grd2.Dispose();
	grd3.Dispose();
	this.Dispose(true);
	}         //@exit method do this:         {             if(TearDownEvent != null)             {                 this.TearDownEvent();             }             Application.Exit();         }
