    How to fire a server side function from client side

    Hi all

    I am having a problem here

    Is it possible to fire a server side function from client side?

    ie. I have a function on codebehind

    Sub DoSomething(o as object)

    'do something to o

    End sub

    and on button press I dynamically create few linkbuttons (or something
    else if needed) and for each linkbuttons I would need to launch the
    DoSomething function from codebehind?

    I have read that with javascript __doPostback it would be possible but
    have no idea how to.

    Something like mybutton.attrib utes.add("oncli ck",
    javascript:__do postback('','') ;) ?

    Thanks

      What you describe is called "server-side events". All you need is to setup
      OnClick events for your buttons.

          The problem is the dynamic controls. They get no events when clicked
          on. If I could create them in page_init I could add event handel
          but at the init I have no idea what buttons will be created

              It is very rear when you really need to create controls in code. The proper
              way is to put them in an item template of a databound control and databind
              the control in run-time. Then you can setup all the events in the template.

                  True! I just realised that I might have been able to use repeater on
                  this to make the same thing I am trying to do now

                  Thank you all for your answers. I was too focused on getting the
                  serverside event fired from javascript to see that there
                  might be a better solution.

                      another way of doing this - is to use
                      Page.ClientScri pt.RegisterClie ntScriptBlock() and
                      Page.ClientScri pt.GetCallbackE ventReference() ....
