As the text boxes are "Date" fields, and not "Numeric" fields, you need to use Custom validator (To validate the text box values using a custom javascript code).

You can have a look Here[^] to see how to implement a Custom Validator.

Inside the custom validator javascript function, you should get the date values from the two date fields, compare them and then set args.IsValid = true or false.

Good luck.

With out validation also you can do this.

C#

protected void TextBox2_TextChanged(object sender, EventArgs e)
{
DateTime a = DateTime.Parse(TextBox1.Text);
DateTime b = DateTime.Parse(TextBox2.Text);

if (a > b)
{
Response.Write(("<script>alert('Check date range')</script>");
TextBox2.Text="";
}

But that a is server side check. He needs to validate it on the client.
Moreover you have written the code on TextBox_TextChanged event. So every time a user changes the text, the page will post back, which would be very annoying. This is not the best practice.
