GridView RowStyle dependent on a property of the item the row is bound to

[Frinavale]

I'm currently using a GridView and I want to set the CssClass for the Row depending on a property of the object that the row is being bound to.

I tried the following:

<asp:GridView id="searchResultsGrid" runat="server" AllowPaging="true" PageSize="20" AutoGenerateColumns="false">
 
<!-- The following line doesn't work because apparently "Code blocks 
aren't allowed in this context -->
   <RowStyle CssClass="<%#IIF(DataBinder.Eval(Container.DataItem,"NeedsAttention","red","") %>
 
  <Columns>
<!--............-->
  </Columns>
</asp:GridView>

Now I could simply handle theGridView's RowDataBound event and change the css class of the row there...but I'm trying to keep a clear separation between the UI and the page/business logic layers.


I have no idea how to accomplish this and I'm looking forward to hearing any suggestions.

Thanks,

I have discovered that this is impossible.

I cannot do this in declarative markup.

Nearly all of GridView's declarative properties (including GridView.RowStyle) are grid-level settings rather than row-level. Apart from TemplateFields , they are not bound data containers, so they don't have access to the data in their rows.

This means that I have to do this in my .NET code during the the OnRowBound event.

Disappointed,
