Too many characters in character literal - what does it mean, and how to fix?

[zman77]

Hello,

I have a bunch of Image Buttons in my code. When I leave them as they are, I can build my project without problems. However, when I add OnClick to an image button, I get the error:
Too many characters in character literal

For example, the following builds with no problems:

<asp:imagebutton id="myImgBtn" style="Z-INDEX: 102; LEFT: 82px; POSITION: absolute; TOP: 8px" runat="server" ImageUrl="images/myBtns/order.gif" BorderStyle="None" ToolTip="Order"></asp:imagebutton>
 

That same line, with OnClick added, does not build, and I get the above mentioned error:

<asp:imagebutton id="myImgBtn" style="Z-INDEX: 102; LEFT: 82px; POSITION: absolute; TOP: 8px" runat="server" ImageUrl="images/myBtns/order.gif" BorderStyle="None" ToolTip="Order" OnClick="dcsMultiTrack('DCS.dcsuri','/ordering/orderbtn', 'WT.ti','Order')"></asp:imagebutton>
 

How can I fix this? I'm trying to add the OnClick code in order to keep stats of button presses (we use webtrends).
Why exactly is that error happening?

I googled for a solution, and found that I could add an attribute to the button in my C# code. However, I was wondering if I can do this straight in asp without resorting to changing the C# code. Oh, this happens with Visual Studio 2005. My machine has the following .Net frameworks: 1.1, 2.0, 2.0 SP2, 3.0 SP2, 3.5 SP1 (also 2.0 SDK and 1.1 SDK)

Thanks for any help.

Are you trying to use a Javascript when you click the imagebutton?

OnClick is a server side event. If you want your client side scripting to catch the event, you want to use OnClientClick.
