{
    if (Convert.ToDateTime(txtFromDate.Text) < DateTime.Today)
    {
        _lblErroFromDate.Visible = true;
        _lblErroFromDate.Text = "Please enter valid date !";

You forgot to set AutoPostBack="true".

The TextChanged event wont be fired until the page posts back to the server.

TextBox controls don't post back the page to the server by default when their events occure. You can change this behavior by setting the AutoPostBack property value to true.

I think setting AutoPostBack property to true will solve the problem.
