Hi Phil,
In line express like <%= %cannot be used in server control's
attribute/property, it can only be embeded in plain html fragment. Here is
a blog article mentioned it:
#From the Suggestion Box: Why can't you use code expressions for
properties?
http://weblogs.asp.net/leftslipper/a...de-expressions
-in-properties.aspx
For your scenario, as other member suggested, you can consider define the
javascript function without parameter and manually set the variable in the
javascript function definition like below:
==========
<asp:Control OnClientClick="js_function();" />
.........
<script ....>
function js_function()
{
var param = <%= your server-side code %>
}
</script>
==================
Also, for server control property, it support two kind of inline
expresssion:
1. DataBinding expression <%# %>
You can use it to set attributes such as:
<asp:TextBox ... Text='<%# FunctionName() %>' .../>
the "FunctionName" can be defined in codebehind(public or protected),
however, to make the databind expression get executed, you need to call
"DataBind" method on the control or it s parent control.
Here is former thread I've mentioned something on this:
http://groups.google.com/group/micro...rk.aspnet/brow
se_thread/thread/356a59a676948d03/2eec23b49e63dd96
2. There is a new feature in ASP.NET 2.0 called custom Expression Builder
#Expression Builders in ASP.NET 2.0

#The CodeExpressionBuilder
http://weblogs.asp.net/infinitiesloo...odeExpressionB
uilder.aspx
You can use such expression builde to embed code expression into server
control's tag to as to intialize control property with some programmtic
values.

Subject: How to pass a C# parameter as an argument of a javascript method ?
Date: Thu, 12 Jun 2008 11:06:23 +0200
>
Hi,
I've tried this:
<asp:Button ID="Save" runat="server" Text="OK" OnClick="ServerSave"
OnClientClick="SaveParam (<% Util.MaxTags %>)" />
but if fails... Util is a C# class, MaxTags a static member.
Any idea ?
Philippe
