How to make the grid cell ignore all keys pressed, except numbers in WinForms GridControl?

Platform: WinForms |
Control: GridControl
Tags: keyhandling

CurrentCellKeyPress event

This can be achieved by handling the CurrentCellKeyPress event of the WinForms GridControl and when the key is not a digit, then set the e.Handled to “True”.


//set the cells of the 3rd column into integer type.
this.gridControl1.ColStyles[2].CellValueType = typeof(int);
//using  CurrentCellKeyPress
void gridControl1_CurrentCellKeyPress(object sender, KeyPressEventArgs e)
    GridCurrentCell cc = this.gridControl1.CurrentCell;
    //condition for ignore key other than numbers
    if (this.gridControl1[cc.RowIndex, cc.ColIndex].CellValueType == typeof(int) && !char.IsDigit(e.KeyChar))
         e.Handled = true; //ignore it
        MessageBox.Show("Invalid entry");


'set the cells 3rd column into integer type
Me.gridControl1.ColStyles[2].CellValueType = GetType(Integer)
'using  CurrentCellKeyPress
Private Sub gridControl1_CurrentCellKeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs)
    Dim cc As GridCurrentCell = Me.gridControl1.CurrentCell
    'condition for ignore key other than numbers
    If Me.gridControl1(cc.RowIndex, cc.ColIndex).CellValueType Is GetType(Integer) AndAlso (Not Char.IsDigit(e.KeyChar)) Then
        e.Handled = True 'ignore it
        MessageBox.Show("Invalid entry")
    End If
End Sub
