Text not visible in DropDown

[jmdion]

My AutoCompleteBox seems to work correctly except that the text does not display properly in the DropDown (pls. see screen capture attached).

I am new to WPF controls and I am wondering if this is because the application is a VSTO add-in. This is the container hierarchy:

• AutoCompleteBox is in a WPF UserControl
• WPF UserControl is in an ElementHost
• ElementHost is in a WinForms UserControl
• WinForms UserControl is in a Microsoft.Office.Tools.CustomTaskPane

Hello Jean,

The issue occurs because Expression Blend is losing ItemsSource property of the RadListBox element when the template has been generated. Please add ItemsSource="{TemplateBinding FilteredItems}" to the RadListBox named PART_ListBox inside the control template of AutoCompleteBox and the drop down content will be shown.

I hope it helps.

Hello Maria,

I cannot follow your suggestion because I am not using Blend.

I think this may be a general WPF problem, not specific to the Telerik control. I will do some experiments with Microsoft controls and I will report back.

Thanks.

I would like to close or remove this thread. I have started an online course on WPF and it will be a few weeks before I re-try to solve the original problem.

Thanks again.

Problem solved!

The members of my data type were fields while they should have been properties.

In the debugging output I had this:

System.Windows.Data Error: 40 : BindingExpression path error: 'Name' property not found on 'object' ''Company'

I changed the members to properties and now the values are visible in the dropdown.
