Hello User101,

I am glad you were able to find the assembly that contains the filter-related items for the XamComboEditor.

Regarding getting the selected item to look exactly like the populated item, I am assuming this means that you have an ItemTemplate in your XamComboEditor and you are looking to have the selected item respect that ItemTemplate. Please let me know if this assumption is incorrect, as the following is based on it.

If your ItemTemplate is just text, I would recommend creating a separate property in your ViewModel that allows you to set the DisplayMemberPath to it. This will allow the selected item to look like the displayed item without any template-modification.

If it has other elements, such as images, I would recommend that you navigate to the generic.xaml file commonly found at C:\Program Files (x86)\Infragistics\<your version here>\WPF\DefaultStyles\XamComboEditor and pull in the default style for XamComboEditor. Inside this template, there exists a SpecializedTextBox element that I would recommend that you replace with a ContentPresenter. You can bind this ContentPresenter's Content property to the SelectedItem property of the XamComboEditor and bind the ContentTemplate property to the ItemTemplate property of your XamComboEditor.

I have attached a sample project to demonstrate the above. I hope this helps.

One limitation of this is that this solution may prevent your user from actually entering "edit mode" as the editable SpecializedTextBox in this case will have been replaced. The drop-down can still be opened, and the editor edited that way, but the auto-complete and "edit mode" will be gone with this route.

Please let me know if you have any other questions or concerns on this matter.

Sincerely,
Andrew
