I have the code below to page a gridview but the query.skip doesn't work.

query.take works but qery.skip doesn't work

It always returns the first 5 rows of the datatable

Thanks,




Gridview

<asp:GridView Width="100%" ID="gvwData" CssClass="datatable" PageSize="5" runat="server"
            PagerSettings-Visible="true" >
</asp:GridView>


Code behind

Imports System.Linq.Dynamic

    Sub bindGrid()
        'bind grid data
        With Me.gvwData
            .Width = WebControls.Unit.Percentage(100)
            .EnableViewState = False
            .AutoGenerateColumns = False
            .DataSource = Me.GetFilteredData()
            .DataBind()
        End With
    End Sub

    Private Function GetFilteredData() As DataTable
        Dim dtFilterData As New DataTable
        'dynamic query against datatable 
        'select everything from currentdataset
        Dim query = From dv In Me.CurrentDataTable Select dv
        If Me.PageSize = -1 Then
            dtFilterData = query.CopyToDataTable
        Else
            'Skip the first (Me.CurrentPageIndex * Me.PageSize) records and take the next (pagezise)
            ' dtFilterData = query.Take(Me.PageSize).CopyToDataTable
            dtFilterData = query.Skip(Me.CurrentPageIndex * Me.PageSize).Take(Me.PageSize).CopyToDataTable
        End If
        Return dtFilterData
    End Function

did you have primary in datatable?

and
Me.CurrentPageIndex  was changed?

and did you debug your code and watch dtFilterData?

Never mind.. it was me all the time.

In my itemdatabound subroutine I kept using  Me.CurrentDataTable, which was the original datatable,  instead of dtFilterData.

Of course I was always displaying the same rows.. duh...

Thanks any way.
