pass more than one parm

hey all,
i'm in a template column of a gridview. i have a hyperlink in the Item
Template and i'm trying to do a custom binding expression to it. So far i
have the following:

Eval("FILE_ID", "~/ViewFile.aspx?Id={0}")

Is there a way to pass more than one parm? If so, could someone please show
me the syntax?

thanks,

rod,

Inside your binding syntax, you'll have to call another formating function
that takes multiple arguments. Try this:

<ItemTemplate>
<asp:HyperLink ID="lnkTest" runat="server"
NavigateUrl='<%# String.Format("~/Temp.aspx?id={0}&id2={1}", Eval("id1"),
Eval("id2")) %>' Text="Link 1"></asp:HyperLink>
</ItemTemplate>

If your binding is more complicated than what string.Format() can handle
then declare a function in your codebehind and call that function inside your
templated column. Something like:

inside your codebehind declare a function...

public string FormatURL(string arg1, string arg2)
{
return string.Format("~/Temp.aspx?id={0}&id1={1}", arg1, arg2);
}

<ItemTemplate>
<asp:HyperLink ID="lnkAnotherTest" runat="server"
NavigateUrl='<%# FormatURL(Eval("id1").ToString(), Eval("id2")).ToString()
%>' Text="Link 2">
</asp:HyperLink>
</ItemTemplate>

Hope this helps,
