RadComboBox SelectedValue Assignment Null

Not sure if this is a bug.

I have RadComboBox binded to some objects in RadGridView, In the event code I tried to change the RadComboBox SelectedValue to a valid value, it assigns it to null. I can get by using SelectedItem but that's not quite the same.

Creating grid columns dynamically with MVVM pattern

Hi,

How do we add columns dynamically to a grid with item source bound to a collection? Actually, I want to build a grid to display data in matrix format (The accounts(column wise) is to be mapped against components(row wise)). The number of accounts may grow each time; so are the columns. I have restriction of not allowed to use dataset/datatable.

Regards,

check/uncheck checkbox from code effects parent node checkbox functionality

Hi,

I need an urgent help in tree-view control. I am not able to attach the sample project which has the problem i am facing.
when i am binding a boolean property to checkstate using code behind and converter as suggested the parent node is behaving in a crazy manner.
If i check 2 out of 3 children under a parent node then parent node is showing state of checkbox as intermediate. But if i check the 3rd child also the state of parent node remains intermediate which should get changed to on(checked) or if i uncheck one of the child node then the parent node state changes to off(unchecked) which should remain in intermediate.
I think there is some bug in the control. but if there is some trick which can fix this will help me a lot. I tried to create a support ticket also but its showing some server error.
Thanks for any help.

thanks,
Anil
