I'm trying to add onclientclick javascript code to an Image Button from VB code behind.   if I add it in directly in the aspx, it works OK.   Like this:  

<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="../Images/DateSelector.gif"
                onclientclick="imageClick();

but if I add from server in code behind like below, it does not work; the javascript imageClick() is never executed when the button is clicked;  what am I doing wrong?

ImageButton1.Attributes.Add("onclientclick", "imageClick();")

I had something like this with PHP and adding ;return false; at the end fixed it for me on a jquery issue. Now, I have no clue about VB but worth a try.

ImageButton1.Attributes.Add("onclientclick", "imageClick();return false;") 

Open in new window

Ah, yes.  Your answer rung a bell with me.  Ya have to use onClick with return false.  This is equivalent to onclickclient.   The return false tells the client to NOT pass the click event along to the server;  return true will pass it along to the server.

ImageButton1.Attributes.Add("onclick", "imageClick();return false;")
