Sorting for dynamically adding lbl field in GridView

[ISA Cody]

How to enable the sorting for dynamically setting the lbl field text in a GridView. Below is the code for the GridView and .cs code where i am setting the value for the dynamic label field. The question is, I am not able to apply the sorting expression for this particular asp:template similar to other templates.\[code\] <asp:GridView ID="gvAlertsStatus" runat="server" AllowSorting="true" OnSorting="gvAlertsStatus_Sorting" AutoGenerateColumns="false" OnRowDataBound="gvAlertsStatus_RowDataBound"> <Columns><asp:TemplateField HeaderText="Owner" SortExpression="UsrName" ItemStyle-Width="120px" > <ItemTemplate><%#Eval("UsrName") %></ItemTemplate> </asp:TemplateField><asp:TemplateField HeaderText="Last Result" SortExpression="lblLastResult" ItemStyle-Width="40px" ItemStyle-HorizontalAlign="Center" > <ItemTemplate><asp:Label runat="server" ID="lblLastResult" Font-Bold="true"></asp:Label></ItemTemplate> </asp:TemplateField><asp:TemplateField HeaderText="Active" SortExpression="Active" ItemStyle-Width="60px" > <ItemTemplate><asp:Label runat="server" ID="lblActive" Text='<%#Eval("Active") %>' ></asp:Label></ItemTemplate> </asp:TemplateField> </Columns></asp:GridView>\[/code\].aspx.cs code\[code\]public void gvAlertsStatus_RowDataBound(object sender, GridViewRowEventArgs e){ if (e.Row.RowIndex >= 0) { Label lblLastResult = (Label)e.Row.FindControl("lblLastResult"); // Get the dates DateTime dtSuccess = (eScan.Lib.Shared.Utils.IsDate(lblSuccess.Text)) ? DateTime.Parse(lblSuccess.Text) : DateTime.MinValue; DateTime dtFailure = (eScan.Lib.Shared.Utils.IsDate(lblFailure.Text)) ? DateTime.Parse(lblFailure.Text) : DateTime.MinValue; DateTime dtDelay = (eScan.Lib.Shared.Utils.IsDate(lblDelay.Text)) ? DateTime.Parse(lblDelay.Text) : DateTime.MinValue; DateTime dtLastRun = (dtSuccess > dtFailure) ? dtSuccess : dtFailure; // Set up the Last Result label lblLastResult.Text = (dtSuccess > dtFailure) ? "Success" : "Fail"; }}protected void gvAlertsStatus_Sorting(object sender, GridViewSortEventArgs e){ // Set up the sort direction SortDirection sd = SortDirection.Ascending; // If the same column is clicked, then alternate sort direction if (e.SortExpression.Equals(ViewState["SortExp"])) sd = ((SortDirection)ViewState["SortDir"] == SortDirection.Descending) ? SortDirection.Ascending : SortDirection.Descending; // Save the states ViewState["SortExp"] = e.SortExpression; ViewState["SortDir"] = sd; // Sort the view and rebind that DataView dv = (DataView)gvAlertsStatus.DataSource; dv.Sort = e.SortExpression + " " + ((sd == SortDirection.Descending) ? "DESC" : "ASC"); gvAlertsStatus.DataSource = dv; gvAlertsStatus.DataBind();}\[/code\]
