Sorting in RadGrid

[hamda]

Hi all,

I'm trying to do sorting to a radgrid but it gives me this error: The datasource 'datasourcename' doesn't support sorting with IEnumerable data. I want to do sorting the moment the page loaded.

Regards,

Hello Hamda,

The behavior you are observing is not directly related to our RadGrid control. Unfortunately it is the default behavior of ObjectDataSource, which, as the exception's message shows, cannot handle sorting on IEnumerable, but only on DataView, DataTable, and DataSet. However RadGrid does provide option to work-around this limitation of ObjectDataSource control, which you can enable by setting MasterTableView's OverrideDataSourceControlSorting to true.

Thanks Pavlina! it solved half my problem. Is there a possible way to sort a radgrid column by 'the most recent', I want my column to show the last added item as the first item in the grid. Please help.

Thanks,
Hamda

Hello Hamda,

You can skip this default sort behavior and provide your own custom sort order for a column by setting the AllowCustomSorting property of the corresponding table view. With custom sorting enabled, RadGrid displays the sorting icons but does not actually sort the data. Instead, you can perform the custom sorting inside the SortCommand event handler.
