    I have a DataGrid that is bound to a the Values in a ObservableDictionary (my own class) instead of the traditional ObservableCollection. Because of this, I cannot use the build in delete mechanism of the GridView.  I therefore need to implement my own custom delete behavior on the current selected row when the Delete button is pressed.

    My problem is that I cannot get an event when the delete button is pressed.  Neither the Deleted, Deleting or KeyDown events for the DataGrid is firing.  The CanUserDeleteRows property is set to true.

    How can I get an event to fire when the Delete key is pressed?

    Hello Stefan,

    You can try defining your own custom keyboard command provider as shown here.

    Hope this helps.

    All the best,

    Hello,

    I'm new here and hope I'm posting in the right thread.
    I'm implentig an WPF Application using Telerik UI. I have also a DataGrid that is bound to the Values in a ObservableDictionary (self implemented).
    Actually a blank line is always present. The default message "click to add a new row" is removed by me. The position also defined by

    myGridView.NewRowPosition = Telerik.Windows.Controls.GridView.GridViewNewRowPosition.Bottom;

    The blank line must be appear if the user explicitly clicks an add button.
    If I use the ObservableCollection it works as desired. How could I achieve this behavior by using ObservableDictionary?

    Thanks a lot in advance!

    Hi,

    Would you please open a new support ticket on the problem and send us a demo project illustrating the issue when you use your custom ObservableDictionary collection?
