Database update, treeview is not updating

Posted By:      Posted Date: October 01, 2010    Points: 0   Category :ASP.Net

I have a treeview that i fill from a database, when i add a new row to a database, the treeview is not updating.
Even the reload of an internet explorer doesn't help, It does updates only after i press stop debugging button and turn it on again.
Here is the code:

    private void MenusBuilder()
        //Parent menu extraction
        DataSet1.TreeItemRow[] cr = GetTreeItemRows();

        StringBuilder sb = new StringBuilder();
        sb.AppendLine(@"<?xml version=""1.0"" encoding=""utf-8"" ?>");
        sb.AppendLine(@"<div id=""menu"">");

        string XmlSiteCreator = CreateXmlDataSource(cr, sb);

        XmlDataSource1.Data = XmlSiteCreator; //Tree Menu
        TreeView1.DataSourceID = XmlDataSource1.ID;

    public static DataSet1.TreeItemRow[] GetTreeItemRows()
        using (DataSet1TableAdapters.TreeItemTableAdapter tita = new DataSet1TableAdapters.TreeItemTableAdapter())
            DataSet1.TreeItemDataTable tidt = tita.GetData();
            DataSet1.TreeItemRow[] pmr = (from f in tidt select f).ToArray();
            return pmr;

(XmlSiteCreator returns the right xml f

Help with updating database with values from Repeater control using c#


Hello, I'm new to ASP.NET 3.5 with C#. I really need some help.

I used a Repeater control to create a simple (editable) list where, when a user logs in, they can edit their list of expenses.  The ASP page works fine.

 My issue is with the code-behind.  I am really confused with how to extract the values from the repeater control. The FindControl method does not seem to be working.  Also, the code I am using resets my 'Amount' values back to 0.00. (0.00 is the amount the user sees when they first encounter the page).

 Here's a portion of the code on the ASP page:

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1"





<td><asp:Label ID="lblExpId" runat="server"  Text='<%# Bind("ExpId") %>'></asp:Label> </td>

 <td><asp:Textbox ID="lblExpense" runat="server" Width= "190px" Text='<%# Bind("ExpenseName") %>'></asp:Textbox> </td>

 <td><asp:Textbox ID="txtAmount" runat="server" Width= "100px"

Gridview's in Update Panel not updating

I have 2 gridviews in an update panel that for some reason will not update.  There is no data entry, paging, sorting going on, the data is just there to be displayed.  I'm using a timer that initiates every 5 minutes to trigger the updatepanel.  I also have an updatepanel on an additional page where I am also using a trigger to fire the updatepanel with 2 charts and 1 oneline/column gridview.  The 2 charts update just like they are supposed to however the gridview does not. Here is the code for the 2 Gridview aspx page:</head> <body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:Timer ID="Timer1" runat="server" Interval="300000" Enabled="True"> </asp:Timer> <br /> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" /> </Triggers> <ContentTemplate> <table class="style1"> <tr>
