but it does not work

why ???

what can i do

Answer 1

According to the c# code, each item in the DataSource if of DataGridColumn type and one of its properties is Header, just like you’ve set in DisplayMemberPath.

In the SelectedItem you should have direct access to one of those objects (if any of them is selected), so so it’s still of DataGridColumn type. Just try to use this line in xaml:

<TextBox Name="txtGridHeader" Margin="2" Text="{Binding ElementName=Columnslst, Path=SelectedItem.Header}" ></TextBox>

Let me know if it worked for you.
