Change the RegularExpressionValidator's ValidationExpression at cl
 
I have a radio button list, a textbox representing SIN or EIN based on my radio button list selection so I put 2 regularexpressionvalidator to evaluate the value of textbox.

EIN must be (for simplicity) with this format (2 digits) like 12 (ValidationExpression="\d{3}-\d{2}")

and SIN must be (for simplicity) with this format (3digits-2digits) like 123-45 (ValidationExpression="\d{3}-\d{2}")

It works well. The problem is: When I change the redio buttons selection, I do not want page to be refreshed. What is the right way?

I have used Microsoft validation controls in all pages so I want to generate the same format error message if I need to bypass the validations controls.

I put all the aspx.cs and asp code at the end of this email.

Please help. Thanks for your help.

Regards

This is the ASPX.CS file

private void RadioButtonList1_SelectedIndexChanged(object sender, System.EventArgs e)

{


if(RadioButtonList1.SelectedValue.Equals("1")) //THIS IS EIN

{


ExpSSN.Enabled = false;

ExpSSN.Visible = false;



ExpEIN.Enabled = true;

ExpEIN.Visible = true;

}

if(RadioButtonList1.SelectedValue.Equals("2")) //THIS IS SSN

{


ExpEIN.Enabled = false;

ExpEIN.Visible = false;


ExpSSN.Enabled = true;

ExpSSN.Visible = true;

}



}

private void Button1_Click(object sender, System.EventArgs e)

{

Response.Redirect("rblist.aspx");

}

This is the ASPX file
