You don't need javascript or the OnClientClick features at all. As Cerebrus mentioned, the CustomValidator option will work just as easy. Better yet, the RequiredValidator may even be easier, if you're just making sure something is in your textbox, as it will check if it is empty. If it is empty, it'll let you know. if not, it will process your code.
Read on both the CustomValidator and the RequiredFieldValidator here: http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/validation/default.aspx On Aug 17, 10:20 pm, Suraj <[email protected]> wrote: > Hi, > > I have a search button I my aspx page.
