    Adding a datatemplate to a listbox seems to break the automatic "startswith" search. I was hoping that overriding ToString() might help, but it doesn't seem to. 

    Can anybody point me in the right direction?




    class ItemVM
            public StyleDefinition Style { get; set; }
            public string TagText { get; set; }

            public override string ToString()
                return Style.Description;

                            <TextBlock Text="{Binding Style.DisplayName}" />
                            <TextBlock Text="{Binding TagText}" HorizontalAlignment="Right"/>

    Hello Michael,

    Thank you for the provided code snippet. 

    We had an issue related to the StartsWith TextSearchMode which is logged in our feedback portal. The fix for that issue is available with our latest internal build version: 2018.1.205 and will also be available with R1 2018 SP2 Release. You can download the latest internal build from the Download section of your Telerik account under Latest Internal Builds.

    I tested the described behavior with the 2018.1.205 version build and it is working as expected. I am attaching a sample project demonstrating this for your reference. I also included the dll from that build in the libs folder for your convenience.

    Please note that between typing different letters, you have to wait 800 ms before the typed text is reset. You can change that by setting the TextSearch.AutoCompleteTimeout property in the MainWindow of your application like so:
    Telerik.Windows.Controls.TextSearch.AutoCompleteTimeout = TimeSpan.FromSeconds(2);

    I hope this helps.
