Dynamically changing the regular expression of Regular Expression validator

[VSK]

Hi all,

I have a .ascx file with

dropdownbox (SSN, EmpName)
textbox
submit button
regular expression validator( controltovalidate is the above textbox)

Now i want to change the Regular Expression of the validator based on the
dropdownlist item selected.
So i have written the following code in .ascx.cs file

private void ValidateSearchText()
{

if(drpSearchField.SelectedItem.Text == "EmpName")

{

genericRegExpression.ValidationExpression = @"^[A-Za-z\-]+$";

genericRegExpression.ErrorMessage="Please enter only characters for
LastName" ;

}else{

...........................

}

}

This method will be called when the button is clicked.

The problem is that the validator is emitting error mesaage as expected.

Has anyone tried this. Please suggest on this.

Thanks

VSK

More experienced folks could hlp you more on this, but
I'd say try dynamically creating the RegularExpressionValidator, and add it
to the Controls collection.

What do you mean

The problem is that the validator is emitting error mesaage as expected. What is the error?
