Hi,
I have used Self Referencing Hierarchy successfully with Telerik.Web.UI.dll Version: 2008.2.723.20.
As my organization moved to dot net 3.5, I have tried using Telerik.Web.UI.dll Version:2008.2.1001.35. But I kept getting an error with the following line in Page_Load:
RadGrid1.MasterTableView.FilterExpression = "ParentID = 0";
Error says:
No property or field 'ParentID' exists in type 'DataRowView'
If I don't set the FilterExpression, Self Hierarchy doesn't work. Can someone help me with this ASAP as this is an urgent requirement?
Regards,
Nanda Kishore

Hi Nanda,
With the .NET 3.5 build of RadGrid for ASP.NET AJAX and LINQ filter expressions enabled (EnableLinqExpressions = true), the filter expressions set for the grid either internally by its filtering mechanism or manually in code should conform to the LINQ expression syntax instead of the old T-SQL syntax. Only thus they will be evaluated properly by the control.
Thus the filtering expression should look similar to the following:
