Answer 1

Try this code

 Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing

        If DataGridView1.CurrentCell.ColumnIndex = 2 Then

            AddHandler CType(e.Control, TextBox).KeyPress, AddressOf TextBox_keyPress

        ElseIf DataGridView1.CurrentCell.ColumnIndex = 1 Then

            AddHandler CType(e.Control, TextBox).KeyPress, AddressOf TextBox_keyPress1


        End If

    End Sub

    Private Sub TextBox_keyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs)

        If Char.IsDigit(CChar(CStr(e.KeyChar))) = False Then e.Handled = True

    End Sub

    Private Sub TextBox_keyPress1(ByVal sender As Object, ByVal e As KeyPressEventArgs)

        If Not (Char.IsDigit(CChar(CStr(e.KeyChar))) Or e.KeyChar = ".") Then e.Handled = True

    End Sub

TextBox_keyPress Event for only numeric

TextBox_keyPress1 Event for numeric with decimal value
