True, False. Is there any server-side event I can catch when the user simply submits the form in a situation like the one I described? (basically, imagine an input field with a submit button that is an image and NOT a "regular" Button). The onclick@server is not ran. The Grid is being binded to a SqlDataReader, not a DataSet, so I have to rebind when the user navigates in the pages. j >Kirk > >-----Original Message----- >From: Joćo Pedro Martins [mailto:[EMAIL PROTECTED]] >Sent: Wednesday, 1 May 2002 7:13 a.m. >To: [EMAIL PROTECTED] >Subject: [DOTNET] Submit by pressing Return - event? > > >Hello, > >question: > >I have a normal runat=server form.
