asp.netdopostback

Is it OK to use __doPostBack()?

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.

Solution

  • 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.
