How to override browser default shortcuts (Ctrl+S, Ctrl+P, Ctrl+X, Ctrl+V) in Wisej?

Hello,

I’m building a designer-style app in Wisej, and I want to override the browser defaults for Ctrl+S and Ctrl+P (so they don’t trigger “Save page” or “Print”) and also make Ctrl+X / Ctrl+V work reliably inside my grid.

For example, in my app I want:

• Ctrl+S → call SaveDraft()

• Ctrl+P → call Publish()

• Ctrl+N → new mask

• F5 → refresh preview

• Ctrl+C / Ctrl+X / Ctrl+V / Delete / Insert / Ctrl+D → manipulate rows in my DataGridView (_gridFelder).

I tried two approaches:

1. Overriding ProcessCmdKey:

   protected override bool ProcessCmdKey(Keys keyData)
   {
   if (keyData == (Keys.Control | Keys.S)) { SaveDraft(); return true; }
   if (keyData == (Keys.Control | Keys.P)) { Publish(); return true; }

   if (_gridFelder?.Focused == true)
   {
   if (keyData == (Keys.Control | Keys.C)) { CopyRow(); return true; }
   if (keyData == (Keys.Control | Keys.X)) { CutRow(); return true; }
   if (keyData == (Keys.Control | Keys.V)) { PasteRow(); return true; }
   if (keyData == Keys.Delete)             { DeleteRow(); return true; }
   if (keyData == Keys.Insert)             { AddRowBelow(); return true; }
   }

   return base.ProcessCmdKey(keyData);
   }

2. Using a KeyDown handler:

private void Designer_KeyDown(object sender, KeyEventArgs e)
{
if (e.Control && e.KeyCode == Keys.S) { SaveDraft(); e.Handled = true; }
else if (e.Control && e.KeyCode == Keys.P) { Publish(); e.Handled = true; }
else if (e.KeyCode == Keys.F5) { RefreshPreview(); e.Handled = true; }
else if (e.Control && e.KeyCode == Keys.N) { NewMask(); e.Handled = true; }
else if (e.Control && e.KeyCode == Keys.C && _gridFelder.Focused) { CopyRow(); e.Handled = true; }
else if (e.Control && e.KeyCode == Keys.X && _gridFelder.Focused) { CutRow(); e.Handled = true; }
else if (e.Control && e.KeyCode == Keys.V && _gridFelder.Focused) { PasteRow(); e.Handled = true; }
else if (e.KeyCode == Keys.Delete && _gridFelder.Focused) { DeleteRow(); e.Handled = true; }
else if (e.KeyCode == Keys.Insert && _gridFelder.Focused) { AddRowBelow(); e.Handled = true; }
else if (e.Control && e.KeyCode == Keys.D && _gridFelder.Focused) { DuplicateRow(); e.Handled = true; }
}

Problem:

• Browser still intercepts Ctrl+S and Ctrl+P (save/print dialog).

• Ctrl+X and Ctrl+V don’t trigger at all.

? What’s the correct way in Wisej to fully disable browser default shortcuts and route them to app logic (especially in a DataGridView)?

Thanks in advance!
