ComboBox IsEditable Binding

[Hussein]

Hi,

I'm trying to bind IsEditable property of the RadCombobox using the following

The combobox is converted to edit mode actually but I cant type anything with the keyboard on the combobox to search

its binding to be true with MouseDoubleClick Event but it doesn't work

any advice...

thanks;

IsEditable="{Binding AccChartMain_IsEditableCommand,Mode=TwoWay}"
