Sorting Problem

[Andy Green]

Hi

I have a RadGrid, datbound in code behind using a dataclass to get the data.

I want to implement sorting and paging, but when I turn it on I get the following error in the _ItemCommand.
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I guess I need to check here that I'm actually looking at a row, If I'm correct how do I do that. If I'm wrong what do I need to do.

This is the start of my code:

   Protected Sub rgUsers_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgUsers.ItemCommand


        Dim User_ID As Guid = e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("UserId")
        Dim CommandName As String = e.CommandName

        Select Case CommandName
            Case "EditUser"

Hello Andy,

This is most probably caused by an improper population of the control with data. The best approach in this case, is to use the NeedDataSource event handler or declarative datasource. When using declarative data sources or the NeedDataSource event, RadGrid can automatically accommodate the appropriate database operations without the need for you explicitly handle any sorting, paging, grouping, and so on.

I hope it gets you started properly.

Best wishes,
