OpenDropDownOnFocus no longer working in 2010 Q2 SP2

[Daniel]

Hi

Previously in the Q1 SP2 controls we had a combo box with:

OpenDropDownOnFocus="True"
IsEditable="True"
IsReadOnly="True"

Which gave us a combo where the user could type in, but only match existing items and when it received focus it popped open.

Now, when IsEditable is True the OpenDropDownOnFocus does not work.

We've tested this in a clean project outside our RadGrid and the bug still remains

Hello Daniel,

I tried this with our latest release 2010.2.924  but was not able to reproduce it. Could you send us a small project or code snippet that would help us find what is wrong. Also are you using Silverlight 3 or 4 .

Best wishes,
Boyan

Silverlight version 4.

We are using the same version of the Telerik controls as you have said.

Here's the sample code

Hello Daniel,

I just tested this in a simple project using the latest binaries (Q3 2010 Beta) and the combobox opens on focus. Please download it and give it a try.
