You should be able to. I've done it with VB so you should be able to do it in C#. Here's an example:
In my html I have:
<div id="Hello" onmouseover="<%# (GetMouseOverJavascriptFn()) %>" onmouseout="<%# (GetMouseOutJavascriptFn()) %>" runat="server">
In my code behind I have:
Protected Function GetMouseOverJavascriptFn() As String
return = "document.getElementById('elemId').style.visibilit y='visible'"
End Function
Protected Function GetMouseOutJavascriptFn() As String
return = "document.getElementById('elemId').style.visibilit y='hidden'"
End Function
This is the only context in which I've done it. So the key is you put your function in
<%# functionName %>
However, the thing to remember is that VB/C# are server-side so you cannot call them as you would a JavaScript function. The functions in the example above get run the first time the page is generated. Once the page is running on the client machine, the only way you can call VB/C# functions is through a postback to the server.
