I am using a Telerik Radgrid ,I have a web form which loads the grid with data by querying against a stored procedure ,the grid is loaded with almost 10 fields but I want to store just the first field (example: UserId) in session and use it on the same page.
Can any one tell me what should I do to retrieve first field from the output(which is dataset)??

Below is my code:
Protected Sub RadViewAllGrid_NeedDataSource(ByVal source As Object, ByVal e As Telerik.WebControls.GridNeedDataSourceEventArgs) Handles RadViewAllGrid.NeedDataSource
        RadViewAllGrid.DataSource = dataaccess.GetEnrollment
    End Sub
 
Dataacess:
 
Public Function GetEnrollment() As DataTable
            Dim dm As DataManager = Nothing
            Dim ds As DataSet = Nothing
            Dim params As List(Of DataParameter) = Nothing
            Dim errMsg As String = String.Empty
 
            Try
                dm = New DataManager(ConnectionString)
                params = New List(Of DataParameter)
                ds = dm.ExecuteQuery(DataProviderType.SqlClient, EnrollUtility.SP_CHECKUSERIDBYADMIN, ReturnType.DataSetType, CommandType.StoredProcedure, Nothing)
 
 
                Return ds.Tables(0)
 
            Catch ex As Exception
                Throw ex
            Finally
                If Not dm Is Nothing Then dm.Dispose()
            End Try
 
        End Function

I am sorry the output is a datatable......
To be more clear, for eg my datatable has 3-4 columns but I need to get all the values of column 1(Userid)  and store it in a session variable and pass this session variable to another procedure to update data relevant to that particular ID. How do I do it?

Do you want to get all the values in the first column (say 20 records) or you want those records which are selected by the user from UI?

What I think you want is that you have this grid in the page where user selects few records and want to do an update on those records.Correct.If that is the case,here is a good article(may be you have seen it).

http://www.telerik.com/help/aspnet-ajax/grdretrieveprimarykeyfieldvaluesforitems.html

In the given example where you use response.write,instead of that keep adding the values as a session string with comma separator.

Say the user click record 1,4,7 then the session variable would be
Session["idselected"]=Session["idselected"].tostring()+",",e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("ID")
