在datagridview的.keypress事件中判断是否是数字键，不是数字键就禁掉

问题解决了,发出来共享一下.

Public EditCell As DataGridViewTextBoxEditingControl

Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
EditCell = CType(e.Control, DataGridViewTextBoxEditingControl)
EditCell.SelectAll()
AddHandler EditCell.KeyPress, AddressOf Cells_KeyPress
End Sub

Private Sub Cells_KeyPress(ByVal sender As System.Object, ByVal e As KeyPressEventArgs)
If e.KeyChar <> Chr(8) And e.KeyChar <> Chr(13) And (e.KeyChar < Chr(48) Or e.KeyChar > Chr(57)) Then
Beep()
Beep()
e.KeyChar = Chr(0)
End If
End Sub

1。继承datagridview类，
2。控制字符输入

不知道能否使用IsNumeric()函数？

请问，如果要针对某一列进行数据的控制要怎么写代码？假如DataGridView中第一列默认，第二列只能输入数字。
