Nested grid control template override

[Wesley]

I'm building keyboard navigation for our grids that relies heavily on the ordering of items in the visual tree. The problem I'm having is that the GridViewToggleButton for a GridViewRow with a nested grid comes after the nested grid in the visual tree.

 

I've been searching through Telerik.GridView.xaml of the appropriate theme to try to find the control template where I could change the ordering of controls, but I have been unable to find the control template responsible.

 

Can you tell me which control template I need to edit for a row inside a grouping that has a nested grid inside?

Hello Wesley,

Thank you for the provided images.

Looking at the radgridviewvisualtree.png I can see that you are using Hierarchical GridView for the child table. The GridViewToggleButton button which you want to move is located in the template of the GridViewRow. What I can suggest you is to extract the default template of the GridViewRow and modify its template to fir better in your scenario. I need to point out that if you are using different themes you will need to modify the GridViewRow default template for every theme as the structure of the control is different. You can take a look at the Editing Control Templates help article which describes how you can get the default template of the controls. In your case, the GridViewRow template is located in the Themes.Implicit/WPF40/OfficeBlack (or your theme)/Themes/ Telerik.Windows.Controls.GridView.xaml.

Give this approach a try and let me know if I was able to help you.
