How to fire ASP.Net button click even from JavaScript

P1ST0LPETE asked
Last Modified: 2012-05-09
Ok, so I have a hidden asp.net button on my page that looks like this:

<asp:Button ID="btHiddenButton" runat="server" OnClick="HiddenButton_Click" />

Then I am trying to programmatically launch the button click event with JavaScript like this:

function BlastChillTypeChange(dropdownlist)

        //Fire the hidden button to initiate server side code:
        __doPostBack('btHiddenButton', 'OnClick');

I know the javascript function is being triggered due to the alert(), but my breakpoints in my asp.net code behind are never hit, indicating that I'm not calling the postback correctly.

What am I doing wrong?
