Hi

Given the code below, when the Grid is rendered, there is no filter icon on the column. Can you tell me what else I need to do to get the filter icon (therefore enabling filtering) to appear on a dynamic column.

    
             Dim UDFCellStyle As Windows.Style = Me.FindResource("UDFCellViewStyle")  
        
                    For Each UDFItem In Me.CMXEvent.UDFItems  
        
                        Dim UDFColumn As New Telerik.Windows.Controls.GridViewDataColumn  
        
                        UDFColumn.CellStyle = UDFCellStyle  
        
                        UDFColumn.HeaderText = UDFItem.UDF.Name  
        
                        UDFColumn.IsFilterable = True 
        
                        UDFColumn.DataContext = UDFItem  
        
                        Me.grdMembers.Columns.Add(UDFColumn)  
        
                    Next

Thanks

Hello Paul,

You should set DataMemberBinding (or UniqueName) for the generated column in order to bind to a specific property of your data source element. If the specified property is a build-in type (like int, string, etc.) you will be able to filter right now. If your property is a custom object, you should implement IEquatable<> and IComparable<> interfaces in your object in order for the grid to be able to perform the operation.

Hope this helps.

All the best,
