GridView Sorting

Hi,
I guess i am missing something bc sorting does not work.

                                                <asp:GridView ID="gridUserInfo" AllowPaging="True" AllowSorting="True"  runat="server"
                                                AutoGenerateColumns="False" CellPadding="4" DataKeyNames="UserID"
                                                ForeColor="#333333" GridLines="None"
                                                OnPageIndexChanging="gridUserInfo_PageIndexChanging" OnSorting ="gridUserInfo_OnSorting" >
                                                    <PagerSettings PageButtonCount="15" Position="TopAndBottom" />
                                                    <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
                                                    <Columns>
                                                        <asp:TemplateField SortExpression="UserID"  HeaderText="Select">

Here is a piece of code I used in the past:

Private Sub DataGrid1_SortCommand(ByVal source As System.Object, ByVal e As System.Web.UI.WebControls.DataGridSortCommandEventArgs) Handles DataGrid1.SortCommand
        viewstate.Add("sortfield", e.SortExpression)
        If viewstate("sortdirection") Is Nothing Then
            viewstate.Add("sortdirection", "ASC")
        Else
            If viewstate("sortdirection") = "ASC" Then
                viewstate("sortdirection") = "DESC"
            Else
                viewstate("sortdirection") = "ASC"
            End If
        End If
        Session("lastColSorted") = e.SortExpression.ToString & " " & viewstate("sortdirection").ToString()
        tblView.Sort = e.SortExpression.ToString & " " & viewstate("sortdirection").ToString()
        DataGrid1.DataBind()
    End Sub



Good luck!

It was not working for me. Is sorting for datagrid and gridview the same?

Sorry I forgot to put in the page_load:
Public tblView as DataView
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here

        YourDataAdapter.Fill(DataSet1)
        tblView = Dataset1.YourTableName
        If Not Page.IsPostBack Then
            Session("lastColSorted") = "YourColumnName DESC" 'This is just for a default sort
        End If
        tblView.Sort = Session("lastColSorted")
        DataGrid1.DataBind()
    End Sub



Good Luck
