Hi,
I have a RadGridView showing up data using a GridViewDataColumn.CellTemplate with just one column and I want the Windows Narrator to narrate the correct info of the DataRows. Using Inspect.exe I realised that the GridViewCell's LocalizedControlType property is Custom. I tried to create an AutomationPeer for all the RadGridView child hierarchy elements to override the GridViewCellAutomationPeer's properties like LocalizedControlType, Name etc, but Narrator narrates nothing and the Inspect.exe does not focus on the GridViewCell as expected.
So, how can I modify the AutomationPeer elements of a RadGridView or just configure it for customising the Windows Narrator and other accessibility issues?
thanks,,

I am afraid that this would not be a trivial task. In order to override the default automation peer of a control, you need to inherit it and override the OnCreateAutomationPeer method, returning the custom peer there. However, it will be very difficult to force RadGridView to use custom cells.
A possible solution would be to make those changes in the source code and the create a custom build that includes them.
Another option that might help you achieve such results is to use GridViewColumn's CellTemplate to generate custom display elements in the cells. then you can overrider those display elements' UI automation logic.
Can you please specify what goal you are trying to achieve, so that we can think of other possible options?

Hi,
Basically Windows Narrator is narrating "Custom" + more useless data, so I want to override this and set ItemType to "data item" and to bind "Name" and/or other automation peer properties...
thanks!

We will need a bit more time to research the possibilities to customize the behavior without introducing a breaking change. I will write back in this thread as soon as we have any relevant info.
