Thank, Zhivko. This works.

Hello,

Thank you for your feedback.

I have been looking into your code snippet and it seems that currently the XamComboEditor you are using  does not support built-in the  functionality that you are looking for. What I can suggest in order to be able to achieve your requirement is to handle the GotFocus event of XamComboEditor and by using our Utilities class you can get the SpecializedTextBox element from the visual tree. That element displays the SelectedItem’s text in the XamComboEditor. Then you can call its SelectAll method and the text  will be selected when the XamComboEditor gets focus. I have created a sample project in order to show you how you can implement this approach.

Please see the attached project and feel free to let me know if it helps you. 

Thank you for your response, Zhivko. I could reproduce the issue with minor changes. Note that I am using Infragistics.Controls.Editors.XamComboEditor whereas you were using Infragistics.Windows.Editors.XamComboEditor. This is the code after my changes:

MainWindow.xaml:
