I have my own rtf editor (derived from RichTextBox) that I use as in-place editor in grid.

I have my cell renderer derived from GridGenericControlCellRenderer that works fine, I can edit and save my data in my custom editor.

But when I press left or right key the Grid handles this and changes the cell instead of passing this command key to in-place editor and move the cursor.

I tried to override ProcessKeyEventArgs and pass message to my editor, but it doesn't work for some reason.

How to pass control keys to in-pace editor?

an example of the code

class myEditorRenderer: GridGenericControlCellRenderer
protected override bool ProcessKeyEventArgs(ref Message m)
if (activeEditor != null && activeEditor.Visible && activeEditor.Focused)
return activeEditor.RaiseKeyEventArgs(ref m);
return base.ProcessKeyEventArgs(ref m);

class myEditor : RichEditBox
public bool RaiseKeyEventArgs(ref Message m)
return this.ProcessKeyEventArgs(ref m);

Hi Yuri,

Thank you for your interest in Syncfusion Products.

Please refer this KnowledgeBase article that helps to handle the process command key in derived cell renderers.

Let me know if it helps.

Lingaraj S.
