Jquery – ASP.NET postback with jQuery

asp.netjquerymodal-dialogpostbackuser interface

I have a ASP.NET button but recently, I replaced it with a standard HTML button … What I need to do is a postback to an ASP.NET page and ensure a method is called.

The previous button was an ASP.NET button, so I had this event:

Protected Sub btnCancelar_Click(ByVal sender As Object, ByVal e As System.EventArgs) 
    UtilTMP.DisposeObjects()
    Server.Transfer("~\Forms\test.aspx", True)
End

But I was using a button with a JavaScript ALERT and I recently changed to a jQuery UI Modal dialog but it doesn't wait for me to answer the question.. the postback happenes immediatly … so I decided to change to a standard HTML button … but I need to postback to the ASP.NET page and call a method like.

If I just postback it won't call the cleanup

Protected Sub Cleanup()
    UtilTMP.DisposeObjects()
    Server.Transfer("~\Forms\test.aspx", True)
End

See if this helps: http://www.codeproject.com/KB/aspnet/sample.aspx.

Basically, you declare a dummy anchor tag:

<a id="anchorId" runat="server" onclick="return true" onserverclick="foo"></a>

In your code behind, you need to declare a foo method:

protected void foo(object sender, EventArgs e)
{
    // Do something here
}

Then you can invoke this anchor's onclick function with this javascript:

document.getElementById('anchorId').click()
