Question

Is it OK to use __doPostBack() or it is not recommended because it is generated from ASP.Net and we are not sure if they changed it in a next version of ASP.Net.

Answer 1

I would advice against it, since it’s internal stuff of ASP.NET and was never meant to be used directly.

Instead, what I’m doing when I need to “manually” trigger PostBack is adding hidden “server side” button with the proper OnClick:

<asp:Button id="btnDummy" runat="server" OnClick="Foo" style="display: none;" />

Then the JS is:

document.getElementById("<%=btnDummy.ClientID%>").click();

This way I don’t care how post back happens, I just trigger the natural flow of events.
