[RESOLVED] GridView's sort function

[thatzlim]

Hi, I'm trying to do this:

I am working on web app project. I'm using visual studio 2005, .net framework 2.0.

On Business Logic Layer (BLL), I stored the sql query result in UserCollection (UserCollection is a collection of User object which inherits the generic Collection class, User object is a class defined by me). Then passing this UserCollection to Presentation Layer.

On Presentation Layer, I bind this UserCollection to a GridView. I enabled Sorting on GridView. I defined the SortExpression for the column that I want to sort via GridView's SmartTag.

My question is, when I run the application, clicking on the GridView's column header, it will not sort the result. Why is it so? How can I make it able to sort?

Kindly advice in details. Thank you!!!

Could you post your grid view code, the aspx code. It might help solve your problem

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim bllUser As New UserBLL
        Dim colUser As UserCollection = bllUser.GetUser()

        grdUser.DataSource = colUser
        grdUser.DataBind()
End Sub

<asp:GridView ID="grdUser" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" CssClass="cssGridView"  GridLines="None">
<Columns>
<asp:BoundField DataField="UserID" HeaderText="UserID" Visible="False" />
<asp:BoundField DataField="UserName" HeaderText="UserName" />
<asp:BoundField DataField="FirstName" HeaderText="FirstName" SortExpression="FirstName" />
<asp:BoundField DataField="LastName" HeaderText="LastName" SortExpression="LastName" />
<asp:BoundField DataField="DisplayName" HeaderText="DisplayName" SortExpression="DisplayName" />
</Columns>
</asp:GridView>
