How to Suppress KeyDown Event in Windows Forms GridControl

15 Jun 20217 minutes to read

To suppress the TableControlCurrentCellKeyDown event, enable the SuppressKeyPress property in this event. To get the Keys data, override the ProcessCmdKey() method.

1. Suppress the KeyDown event as given in the following code:

        void gridGroupingControl1_TableControlCurrentCellKeyDown(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlKeyEventArgs e)
   
                {
   
                    e.Inner.SuppressKeyPress = true;
   
                }

        Private Sub gridGroupingControl1_TableControlCurrentCellKeyDown(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlKeyEventArgs)
   
                    e.Inner.SuppressKeyPress = True
   
                End Sub

2. Handle the ProcessCmdKey() method to get the keys data as given in the following code:

        protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
   
                {
   
                    Keys keyCode = keyData & Keys.KeyCode;
   
                    switch (keyCode)
   
                    {
   
                        case Keys.Down: Console.WriteLine("down");                 
   
                            break;
   
                        case Keys.Up: Console.WriteLine("Up");
   
                            break;
   
                        case Keys.Right: Console.WriteLine("Right");
   
                            break;
   
                        case Keys.Left: Console.WriteLine("Left");
   
                            break;
   
                        case Keys.PageUp: Console.WriteLine("PageUp");
   
                            break;
   
                        case Keys.PageDown: Console.WriteLine("PageDown");
   
                            break;
   
                    }            
   
                    return base.ProcessCmdKey(ref msg, keyData);
   
                }

        Protected Overrides Function ProcessCmdKey(ByRef msg As Message, ByVal keyData As Keys) As Boolean
   
                    Dim keyCode As Keys = keyData And Keys.KeyCode
   
                    Select Case keyCode
   
                        Case Keys.Down
   
                            Console.WriteLine("down")
   
                            Exit Select
   
                        Case Keys.Up
   
                            Console.WriteLine("Up")
   
                            Exit Select
   
                        Case Keys.Right
   
                            Console.WriteLine("Right")
   
                            Exit Select
   
                        Case Keys.Left
   
                            Console.WriteLine("Left")
   
                            Exit Select
   
                        Case Keys.PageUp
   
                            Console.WriteLine("PageUp")
   
                            Exit Select
   
                        Case Keys.PageDown
   
                            Console.WriteLine("PageDown")
   
                            Exit Select
   
                    End Select
   
                    Return MyBase.ProcessCmdKey(msg, keyData)
   
                End Function
