Hello. I have a special classes: tbTechObject and tbTech. tbTechObject contains tbTech. When I use "full test search" it doesn`t work for column with tbTechObject items (telerik:GridViewComboBoxColumn "ТСИ"). "full test search" work only for string columns. What have I do to "full test search" searches in column with my custom type elements? Thanks.

In order to enable searching for a GridViewComboBoxColumn, you need to set the IsLightWeightModeEnabled property of the column to True. Can you please give the suggestion a try?

I performed some testing of the searching mechanism and was not able to replicate such malfunction. Attached to my reply you can find a short video demonstrating this. Am I missing something? If you are using the control in the same manner, can you please clarify what assemblies version are you using?

Thanks for reply!
I use Telerik.2017.R2/Telerik_UI_for_WPF_2017_2_503_Dev. VS 2017 .net 4.0.
I attached my video demonstrating.

I tested the 2017.2.503 assemblies and the searching is again working as expected on my end. My best guess for the behavior you are experiencing is that it might be due to the implementation of the Equals and GetHashCode methods. You can easily verify this by testing the search mechanism without overriding these methods. Can you please give it a try?

Hello!
I ve tried it without overriding gethashcode and equals, but it does n't work again...
Sorry to hear that you are still experiencing this issue with the text search mechanism.
Though I cannot reproduce it on my end, I can suggest you updating to our latest R1 2018 release. Recently, we made a couple of fixes regarding the search functionality that might be related to behavior you are experiencing as well.

I cannot seem to get the full text searching working for ColumnBox columns or number column. It works ONLY for string columns.
How can we get this working for ALL columns?
As discussed in this thread, in order the search mechanism to be able to work with a GridViewComboBoxColumn, the IsLightweightModeEnabled property of the column needs to be set to True. Can you please confirm that you have set the property on your end? As to searching over a numeric column, you can observe that the control supports it in the Search as You Type WPF Demo. Can you please take a look at it?
