SortBehavior disabled when I set gridDataBoundGrid.DataSource = one object

[Administrator]

I set this.gridDataBoundGrid1.DataSource = Source, where Source is defined as List and is an object list contains information such 'UserID', 'FullName' etc. After I doing this, the grid can be built up normally with correct information. However, the "this.gridDataBoundGrid1.SortBehavior = Syncfusion.Windows.Forms.Grid.GridSortBehavior.DoubleClick" is not working any more.

Could anybody tell me why and how I can sort it out? Thanks.

Hi Preston,

By default sorting is done in a GridDataBoundGrid through the IBindingList.Sort method on the underlying datasource for the grid. This means that the sorting is done on the actual values that are in the datasource (and not the foreign key value which ,is gotten from another datasource). If the dataSource is a DataTable, then this means that the sort is effectively being done by setting the DataView.Sort property on the dataTable.DefaultView.

If your DataGrid is bound to some IList collection and you want your DataGrid to support sorting , you will have to implement the IBindingList.AllowSorting property and the IBindingList.ApplySort method (in addition to the other interface members).


Let me know if you need further assitance.

Can you explain this a bit further. I have a gridDataBoundGrid which is bound to a BindingList. I need to be able to sort!
