Remarks

This example demonstrates how to change default keys used to close an appointment in-place editor. Create a custom in-place editor and override its TextBox_KeyDown method. This sample code specifies that the Ctrl+S shortcut saves changes and closes the editor, while the Ctrl+Z shortcut discards changes and closes the editor.

Form1.cs

private void schedulerControl_InplaceEditorShowing(object sender, DevExpress.XtraScheduler.InplaceEditorEventArgs e)
{
    e.InplaceEditorEx = new MyInplaceEditor(e.SchedulerInplaceEditorEventArgs, e.Appointment);
}

MyInplaceEditor.cs

public class MyInplaceEditor : DevExpress.XtraScheduler.Native.SchedulerInplaceEditorEx
{
    public MyInplaceEditor(DevExpress.XtraScheduler.SchedulerInplaceEditorEventArgs inplaceEditorArgs, Appointment apt)
        : base(inplaceEditorArgs, apt)
    {
    }
    protected override void TextBox_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
    {
        if (e.Control && e.KeyCode == System.Windows.Forms.Keys.S)
        {
            OnCommitChanges();
            e.Handled = true;
        }
        else if (e.Control && e.KeyCode == System.Windows.Forms.Keys.Z)
        {
            OnRollbackChanges();
            e.Handled = true;
        }
        else
            //base.TextBox_KeyDown(sender, e);
            e.Handled = true;
    }
