DataGridView中如何在textbox列中限制输入。

DataGridView是.net2.0的一个新增数据控件，功能比DataGrid增强了很多，但是并没有CellKeyPress事件来限制文本列的输入。我利用一个新增的事件EditConTrolShowing解决这个问题。

Private EditingControl As DataGridViewTextBoxEditingControl

Private Sub datagridview1_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles datagridview1.EditingControlShowing

EditingControl = CType(e.Control, DataGridViewTextBoxEditingControl)

AddHandler EditingControl.KeyPress, AddressOf editingcontrol_Keypress

End Sub

Public Sub editingcontrol_Keypress(ByVal sender As System.Object, ByVal e As KeyPressEventArgs)

‘写上处理语句

End Sub

Private Sub datagridview1_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles datagridview1.CellEndEdit

RemoveHandler EditingControl.KeyPress, AddressOf editingcontrol_Keypress

End Sub

这样就可以解决限制输入的问题，以此类推，很多其他问题都可以通过这个方式解决。
