Hi,

 we have the licensed version of radcontrol. we had used the developer dll versions in our project which we have saved inside the bin folder. This project is used by different users. when we compile the project we get trial version splash screen. Please take this request with utmost urgency.

Regards

Hi,

I would like to replace tabs (Parameters, Patterns) to expandable nodes, so it should look like that:

- |

  + Parameters

         Name       Value    Service

      -     ...            .....       ...... 

      -     ...            .....       ...... 

  + Patterns

         Definition  Value

      -     ...            .....

      -     ...            .....    

Can someone please give me some tips to do it?

Regards,

Michal

Hello.

Please, could you give me an adwace how to use RadWaitingBarElement in RadGridView and run this element. I have try used it in cell_formating, but it do not work.

(it is trial Version: 2010.1 504 , C#, vs 2008 express)

Thank you for advice or source code.

I have a custom object that I am using for databinding. I tried to post the sample as a zip file to repeat the problem I am seeing. Maybe I did my custom objects wrong, I really dont know. However, my problem is this, when binding to Hierarchy data if you select a row and expand the child data is shown, however if you select the next row and expand it, then the first child result loses its binding, and you have no data. I am considering purchasing your product for a project, and need your advice...is this a bug? or is my code incorrect? I have custom objects, and I am not using DataSets or DataTables...nor do I want to use those, so those examples really dont help.
