Populating DataList

[Hamayun Khan]

Hi I want to populate the Datalist control from some data using code below

<asp:DataList Width="100%" ID="DataList2" runat="server" DataSourceID="SqlDataSource2" RepeatDirection=horizontal RepeatLayout="table" RepeatColumns="3" >
  <ItemTemplate>                                            
   <asp:LinkButton runat="server" OnCommand="lnkButtonCommand" CommandArgument='<%# Eval("Region") %>' CommandName="Region">
<%# Eval("Region") %> ' Pass This value to some function If The function retrun false don't create linkbutton just movenext.
</asp:LinkButton>                                            
     </ItemTemplate>                                            
  </asp:DataList>               
 <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:dbase_DataConnectionString6 %>" SelectCommand="SELECT  [Region],[RegionID] FROM [tblregion]"></asp:SqlDataSource>

I want to pass Eval("Region") to some function. if the function return false Then i want not to create this button and check for the next value.
Thanks
