Calling a javascript function with parameter bound to repeater

Question

I'm trying to call a javascript function.

function callSubClass(SubClassName) {
  ...
}

But I am trying to call it inside a repeater where the parameter "SubClassName" is a string bound to my repeater.

<asp:Repeater ID="rptSubClass" runat="server">
  <ItemTemplate>
    <asp:LinkButton Text='<%# Eval("SubClassName") %>' runat="server" ID="linkHomeItem" OnClick='<%# callSubClass(Eval("SubClassName")); return false; %>'/>
    <br />
  </ItemTemplate>
</asp:Repeater>

But every time I run it I get a compiler error saying:

CS1040: Preprocessor directives must appear as the first non-whitespace character on a line Error

Now I know the error is on the OnClick='stuff' but I've tried all I could think of to make it work. Here's a list of what I tried so far.

OnClick='<%# callSubClass(Eval("SubClassName")); return false; %>'
OnClick='callSubClass(<%# Eval("SubClassName") %>); return false;'
OnClick='"callSubClass("+<%# Eval("SubClassName") %>+"); return false;"'

What am I doing wrong? Thanks for any help provided.

Try Like this...Instead of Onclick use OnClientClick to run javascript code.....

OnClientClick='<%# @"callSubClass("""+Eval("SubClassName").ToString()+@""");return false;" %>'
