Missing __doPostback - help!

[James Radke]

Hello,

I have a webform that I am modifying. After the modifications we have three
visible buttons which perform a submit; and one invisible button. What I
would like to do is to submit the invisible button from within a javascript
function.

I am used to doing this by calling the __doPostback function within the
javascript; however since this page only has buttons on it, ASP.NET never
generates the __soPostback function to the web page that is transmitted to
the client - so , is there any way for me to call the submit of the
invisible button from the javascript?

Thanks!

Hi James,

How about adding a Linkbutton with no text as a way of tricking ASP.NET into
rendering the __doPostback code?

<asp:LinkButton id="LinkButton1" runat="server"></asp:LinkButton></P>

Also, you might want to see if there's anything of use in this article:
