Say I have a bunch of objects of type Foo and I create a System.Data.DataTable where I add a couple columns like: // START CODE SNIPPET table.Columns.Add("FooColumn1", typeof(Foo)); table.Columns.Add("FooColumn2", typeof(Foo)); // and then add a few rows: for ( int i=0; i < 50; i++ ) { table.Rows.Add(table.NewRow()); for ( int j=0; j < table.Columns.Count; j++ ) { Foo foo = new Foo(); foo.SomeProperty = rand.Next().ToString(); table.Rows[i][j] = field; } } // now assign the datasource gridGroupingControl1.DataSource = table; //END CODE SNIPPET the problem is that I get jillions of exceptions thrown like this: catched at Syncfusion.Grouping.FieldDescriptor.GetValue(Record record) in :line 0 How can I handle the processing myself so that I can tell it how to display a Foo in a cell (assume that there is some processing I need to do for each Foo such as call a custom method or perform some string manipulation)... Thanks - Daniel

Hi Daniel, I created a sample for the scenario you described and I found a bug in the FieldDescriptor class. I have that fixed now. If you submit a direct-trac incident we can send you a private patch. With that fix you can display custom types. Just make sure not to use public field in that type. Instead use public properties. I attached the sample form I created. With the fix, you can then add columns to the table descriptor in the form "ColumnName.PropertyName". Form1_9412.zip Stefan
