Cannot dynamically assign a BackColor to a datalist

I need to dynamically assign a datalist attribute upon a helper
function receiving data from a querystring. If a user picks a certain
region, i need the datalist to display its back color, or any of its
other objects , as a certain color or css style





....doesnot work as a Parser error renders: Content (' BackColor=') does not match any properties within a
'System.Web.UI.WebControls.DataList', make sure it is well-formed

Re: Cannot dynamically assign a BackColor to a datalist

Do it programatically. You can access the property directly from code as
follows:
assume the name of the datalist is dl

dl.HeaderStyle.BackColor = Color.Red;

Hope this helps,

Re: Cannot dynamically assign a BackColor to a datalist

Thanks for your response. There is no code behind in these scripts/
programs I am using. Inside the Datalist form block, I have:

width="350px" ItemStyle-BackColor="#ccffcc" cellspacing="3">


Providers for
<%= sregionZ %>: <%= Zonecustom() %> HeaderTemplate>
href="re.aspx?zone=<%#Server.UrlEncode(Request.QueryString("zone")) &
"&cregion=" & Server.UrlEncode(Request.QueryString("cregion")) &
"&category=" & (Eval("Category").ToString())%>">
<%# Eval("Category")%>



as you see, I can provide dynamic variables from helper functions in
the headers of my page to stuff inside the Header Template & the
ItemTemplate, but I need to dynamically also change the HeaderStyle
BackColor property here


TIA

Hi,

I suggest you wrap your HeaderTemplate content in a div and
dynamically assign a style to that element. Something like:
