How to make the grid cell ignore all keys pressed, except numbers in WinForms GridControl?
1 min read
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”.
C#
//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");
}
}
VB
'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
