  • The problem is not the grid but the datatemplate. Why you must do that? – Gianluca Conte Sep 14 '18 at 10:23
  • You should get popup1.Child and use VisualTreeHelper to findChild. you can get my code from https://github.com/Ilya-Grigoryan/SynchDataGridScroll.git and see the VisualTreeHelperEx.cs, with this extension you can find any child that you want to. – Ilya Grigoryan Sep 14 '18 at 10:55

No, We can not access controls inside a data template using its names. but,

  1. to assign data source to the grid view, you can do it in the loaded event of grid by type casting sender to gridview.
  2. to get the selected data of grid, you can use the selectionchanged event of grid by type casting sender to gridviewitem.
