Hello,
I bugfixing an application where the following issue happens:
There is a RadViewGrid WPF control implemented. When the filter icon on a column is clicked opens a popup filter window. If I click on any of the filtering operators or the logical operators (I want to change them) the popup filter window immediately closes. I can't open the operator combobox to select any other than the default.
When I click the filter icon on the column again, so opening the popup window again, then I see, that the previously selected operator is stay in selected state (I mean it highlighted). It seems if it has been stucked.
The data which populate the RadViewGrid is coming from a test class (in-memory data) exactly as it is written in your documentation:
http://docs.telerik.com/devtools/wpf/controls/radgridview/populating-with-data/in-memory-date

I made a brand new WPF project to test the filter icon. The solution has only a RadViewGrid control, and I populated it with in-memory data. In this test project the filter window works perfectly, I can open the filtering or logical operator combobox, and select another operator. This means, the Telerik assembIies I use are ok.

Unfortunately I stuck with this issue and need help. Did you expereince any similar issue? What can prevent the filtering/logical operator comboboxes to open and force the filtering popup window to close?

Thank you for any help in advance!

Hello Attila,

As I am not able to reproduce such an issue on my side, may I ask you to open a new Support Ticket and attach a sample project illustrating your exact setup? You can take a look on the Isolating a problem in a sample project blog post for a further reference. By providing us with such a project we will be able to investigate it more precisely, as it seems to be specific for your implementation.

In addition you can find our SDK Examples useful.

Kind Regards,
