Hello,

First of all i would like to say that I'm glad to hear that you are interested in Telerik Controls, and i would like to welcome you to the forums.

First thing's first, there is a VS2010 solution included and it is called CSVS2010.sln.
Please test it with this one, and please set the target platform to X86 is it is not set already.

If you still have this problem please provide more details in which cases this occurs on exactly the steps required to replicate it.

Hope this helps, if you have any other questions or comments, please let me know,

Hi Emanuel,

The samples that i downloaded from http://www.telerik.com/documents/Telerik_RadControls_for_WinForms_Courseware.zip
not including such solution.
Can you send me the relevant link for download?

Regards,
Stas

Hello,

Please download the Free Trial from here and after you install the trial version you will have a Demos application, and under the install folder you have the source for the examples in the Demos application, usually under :

c:\Program Files\Telerik\RadControls for WinForms Q3 2010\Examples\ExamplesCSVS2010.sln

Hope this helps, if you have any other questions or comments, please let me know,

Hi,

I found this solution, thank you.
I want to see working example for custom cell.
All examples that i saw is not working completly.
The last one i saw was http://www.telerik.com/support/kb/winforms/gridview/adding-custom-elements-inside-a-cell-when-it-is-in-edit-mode.aspx,
but Button_Click event is not working. Do you have any idea why?

Regards,
Stas

No response...

Hello Stas,

Just a quick follow up.

The project in the KB article will work properly when using our upcoming service pack. I attached a sample project which demonstrates a workaround for the issue using the Q3 2010 version of RadGridView.

I hope it helps. Please write back if you have additional questions.

Best regards,
Alexander
