This should be easy buy I am missing something.   I am trying to bind a Querystring to a controls property and I can't get the syntax right.    If I bind by Index value it will work - like this.

<uc:FindParts runat="server" id="findParts" Nonexact="<%# Request.QueryString(0)%>" />

Open in new window


If I bind by name string I get a "server tag is not well formed.

<uc:FindParts runat="server" id="findParts" Nonexact="<%# Request.QueryString("test")%>" />

Open in new window


What am I missing?

Try it as a function:
Nonexact="<%# MyFunc() %>"


.VB

Public Function MyFunc(obj test) as String
      return Request.QueryString("test").ToString()
end Function

The issue fixed by replacing the  double quotes with single quotes.

  <uc:FindParts runat="server" id="findParts" InventoryNumbers='<%# IIf(Request.QueryString("Inv") = "", "", Request.QueryString("Inv"))%>' NonExact='<%# IIf(Request.QueryString("E") = "", True, Request.QueryString("E"))%>' Type='<%# IIf(Request.QueryString("T") = "All", "", Request.QueryString("T"))%>'/>

But you also need to databind the page in the load to grab the querystrings.

  Page.DataBind()
