    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.

    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 
    What is the error?

    sorry abt that...

    what i actually meant was it was not showing Error message.(The problem is
    that the validator is NOT emitting error mesaage as expected.)

    but now i got it working...
