I am new to .NET and I am struggling with something quite simple.
Basically I have an ASPX page that calls a ASCX file. The ASCX file has a form field and a calendar button. The calendar button launches a popup window which passes back the selected date to the parent window,form field. The problem is: the form field name always changes because it's in a control. In the ASCX page I call the asp:textbox - txtSetupDate. If I view source after the page has been rendered in IE the form field name is name="_ctl0:txtSetupDate"
How can I overcome this????
