RegularExpressionValidator.IsValid Returns TRUE!?

[Larry Lawhead]

My problem is that IsValid returns TRUE when, based on Validation
Expression, result should be FALSE.

Properties (departing from defaults):
Enable Client Script: False (Just incase it matters)
Validation Expression: [0-9\.,]*

Code Example:

private void cbxAvailable_CheckedChanged(object sender, System.EventArgs e)
{
if(valWeight.IsValid == false)
{
valWeight.ErrorMessage = "Use numbers only.";
tbxProdWeight.Text = "";
}
}

I created a prototype using the same property settings that works just fine.
Here is the code from that example:

private void Button2_Click(object sender, System.EventArgs e)
{
if(RegularExpressionValidator1.IsValid)
{
Label1.Text = TextBox1.Text;
TextBox1.Text = "";
}
else if (RegularExpressionValidator1.IsValid == false)
{
Label1.Text = "";
TextBox1.Text = "";
}
}

I must be overlooking something quit simple here. Any suggestions?

Thanks!

This usually happens when the control is being called
before the validate() function has been called for the
page and therefore your validator has been evaluated
as yet.

Try calling RegularExpressionValidator1.Validate()
before checking the IsValid property.
