How to programmatically set SELECTEDITEM

[Eric]

Hi..
I'm trying to set  the SELECTEDITEM and/or the SELECTED VALUE of combobox in code

this.cmb.SelectedItem = Customers.Name;

But it doesn't work  any ideas?  It's always null

<radcombox  x:name="cmb"  SelectedValuepath="Name"
SelectedItem = "{Binding Name, Mode=TwoWay}"

thanks

Make sure the length of the selected item matches the value in the list.
