ToolWindowPane with Editor and GridControl

Hello,

I have a ToolWindowPane with a toolbar, an embedded Editor (IWpfTextViewHost) and a Gridcontrol.
In the editor the user edits an SQL statement and after pressing a toolbar button the grid is filled with the query data.

When the user presses Del-Key in GridControl the Delete action takes place in the Editor :(

I think the problem is related to the IOleCommandTarget implementation routing all commands to the editor.
I think it should depend on focus, but I don't now to to achieve this ...

Here is my current implementation

        int IOleCommandTarget.Exec(ref Guid pguidCmdGroup, uint nCmdID, uint nCmdexecopt,
                                   IntPtr pvaIn, IntPtr pvaOut)
        {

            var hr = (int)Microsoft.VisualStudio.OLE.Interop.Constants.OLECMDERR_E_NOTSUPPORTED;
            if (pguidCmdGroup == GuidList.guidiNEXTCmdSet) // handling of own comands
            {
               ... code removed here
            }
            else
            if (viewModel != null && viewModel.ViewAdapter != null)
            {
                var cmdTarget = (IOleCommandTarget)viewModel.ViewAdapter;
                hr = cmdTarget.Exec(ref pguidCmdGroup, nCmdID, nCmdexecopt, pvaIn, pvaOut);
            }
            return hr;
        }

viewModel.ViewAdapter is a IVsTextView related to a IWpfTextViewHost

How can I query if TextView has focus or my GridControl has focus and route it to GridControl ?
