I have some ASP.NET Forms. In the Form I am using Client-side script to open a dialog box en get a return value. e.g. I have a customer ID field and with a button a dialog box opens where u can find the right customer. This Customer ID is filled in on the main form (still using Jscript). However, on this main form I need to add some additional information about the customer (Phone-number and such). How do I fire a postback so I can evaluate the CustomerID without having to press another button to get the Postback???<BR><BR>Thx a million,<BR><BR>Henri
