Random COM Exception

[lielael]

Hello, 

I get this exception some times when i open panels in docking control that host a grid with dinamic cells. 

Is it solved in last version?

error HRESULT E_FAIL de una llamada a un componente COM.

Hi lielael,

We are not aware of the issue and unfortunately we were not able to reproduce it in a simple project.
Therefore it would be great if you can send us a project where it can be reproduced so we can debug the exception and get to the bottom of it.
Also it would be helpful if you can tell us what version of the controls you are using so we can try to reproduce the issue with that specific version?

Hi Georgi, 

The version of the assembly is 2013.1.220.1050.

I supose that the problem can be produced by the RadDataPager control , because its the only one that contains RadRadioButton in the dynamic grid cells and panel. 

I can try to create a sample project but as i said, the exception its random.

Regards, 

David

Hi lielael,

As there might be something specific to your scenario and as the issue happens only sometime it would be really hard for us to reproduce it without a project.
Once we have the project and some guidelines on how to reproduce it we can record some tests and try to reproduce it this way, hopefully it will eliminates the random effect of the issue.

So I am looking forward to your project as it will be of great help.
