How to bind DropDownOpened event of a Rad Combo box to a command in the viewmodel

[Srini]

Hi,

How can i route the DropDownOpened event raised by the RadComboBox to a handler in the viewmodel?

Thanks.

Hello Srini,

 
Thank you for contacting us.

I would suggest you to implement attached behavior for the RadComboBox using attached property. In the PropertyCallBack of the attached property you could handle the DropDownEvent and execute the command (in your ViewModel). Attached you can find the sample. 

I hope this helps.
