    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



    <HeaderStyle BackColor="<%= ssponcont %>"</HeaderStyle>

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

      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,

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

          <asp:DataList id="dlstCats" runat="server" RepeatColumns=" 4"
          width="350px" ItemStyle-BackColor="#ccf fcc" cellspacing="3" >

          <HeaderStyle BackColor="#008 000"</HeaderStyle>
          <HeaderTemplate <font class="body11-
          wh">Providers for
          <%= sregionZ %>: <%= Zonecustom() %></font</
          HeaderTemplate>
          <ItemTemplate>< font class="body9bol d-re"<a
          href="re.aspx?z one=<%#Server.U rlEncode(Reques t.QueryString(" zone")) &
          "&amp;cregi on=" & Server.UrlEncod e(Request.Query String("cregion ")) &
          "&amp;category= " & (Eval("Category ").ToString())% >">
          <%# Eval("Category" )%>
          </a></font></ItemTemplate>
          </asp:DataList>

          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

              Re: Cannot dynamically assign a BackColor to a datalist

              Hi,

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

              <HeaderTemplate >
              <div style='backgrou nd-color:<%= ssponcont %>' >
              <font class="body11-wh">Providers for <%= sregionZ %>: <%=
              Zonecustom() %></font>
              <div>
              </HeaderTemplate>

              ============
