文本框应仅允许整数。 在vb.net中不是十进制

Question

I want to allow only whole values and not decimal to the textbox in vb.net. Can anyone help me how to check validation on that.

Answer 1

Only allow numeric input:

    Private Sub TextBoxKeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox.KeyPress
            e.Handled = True
            If IsNumeric(e.KeyChar) Then e.Handled = False
        End Sub
