[Solved] Beginners (?) problem with sorting

To simplify for you, here is (most of) the markup. As you can see it is pretty straight forward and simple, but it doesn't work:

<body>
    <form id="form1" runat="server">
   <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
       <Scripts>
           <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
           <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
       </Scripts>
   </telerik:RadScriptManager>
   <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
   </telerik:RadAjaxManager>
   <telerik:RadSkinManager ID="RadSkinManager1" Runat="server" Skin="WebBlue">
   </telerik:RadSkinManager>
   <telerik:RadFormDecorator ID="RadFormDecorator" runat="server" DecoratedControls="All">
   </telerik:RadFormDecorator>
    <div>
        <telerik:RadGrid ID="DocumentGrid" runat="server" Width="100%" OnNeedDataSource="DocumentGrid_NeedDataSource" AllowPaging="true" AllowSorting="true" OnSortCommand="DocumentGrid_SortCommand">
        </telerik:RadGrid>
    </div>
    </form>
</body>
</html>

And the code behind:

namespace WebApplication1
{
    [Serializable]
    public class Document
    {
        public int Id { get; set; }
        public string ObjectId { get; set; }
        public string ArchiveCode { get; set; }
        public DateTime CreateTime { get; set; }
    }

    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                List<Document> documents = new List<Document>();
                DateTime theTime = DateTime.Now;
                documents.Add(new Document() { Id = 1, ObjectId = "12345", ArchiveCode = "X", CreateTime = theTime });
                documents.Add(new Document() { Id = 2, ObjectId = "12345", ArchiveCode = "Y", CreateTime = theTime.AddDays(1) });
                documents.Add(new Document() { Id = 3, ObjectId = "12346", ArchiveCode = "Y", CreateTime = theTime });

                ViewState["Documents"] = documents;

                DocumentGrid.PageSize = 3;
                DocumentGrid.AutoGenerateColumns = false;
                DocumentGrid.MasterTableView.RetrieveAllDataFields = false;
                DocumentGrid.MasterTableView.AllowMultiColumnSorting = true;

                GridSortExpression sortExpression = new GridSortExpression() { FieldName = "Id", SortOrder = GridSortOrder.Descending };
                DocumentGrid.MasterTableView.SortExpressions.AddSortExpression(sortExpression);
            }
        }

        protected void DocumentGrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
        {
            DocumentGrid.Columns.Clear();
            DocumentGrid.Columns.Add(new GridBoundColumn() { DataField = "Id", HeaderText = "Id", UniqueName = "DocumentIdColumn", SortExpression = "Id" });
            DocumentGrid.Columns.Add(new GridBoundColumn() { DataField = "ObjectId", HeaderText = "ObjectId", UniqueName = "DocumentObjectIdColumn", SortExpression = "ObjectId" });
            DocumentGrid.Columns.Add(new GridBoundColumn() { DataField = "CreateTime", HeaderText = "CreateTime", UniqueName = "DocumentCreateTimeColumn", SortExpression = "CreateTime" });
            DocumentGrid.Columns.Add(new GridBoundColumn() { DataField = "ArchiveCode", HeaderText = "ArchiveCode", UniqueName = "DocumentArchiveCodeColumn", SortExpression = "ArchiveCode" });

            DocumentGrid.DataSource = (List<Document>)ViewState["Documents"];
        }

        protected void DocumentGrid_SortCommand(object source, GridSortCommandEventArgs e)
        {
            GridSortExpression sortExpr = new GridSortExpression();
            switch (e.OldSortOrder)
            {
                case GridSortOrder.None:
                    sortExpr.FieldName = e.SortExpression;
                    sortExpr.SortOrder = GridSortOrder.Descending;

                    e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExpr);
                    break;
                case GridSortOrder.Ascending:
                    sortExpr.FieldName = e.SortExpression;
                    sortExpr.SortOrder = DocumentGrid.MasterTableView.AllowNaturalSort ? GridSortOrder.None : GridSortOrder.Descending;
                    e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExpr);
                    break;
                case GridSortOrder.Descending:
                    sortExpr.FieldName = e.SortExpression;
                    sortExpr.SortOrder = GridSortOrder.Ascending;

                    e.Item.OwnerTableView.SortExpressions.AddSortExpression(sortExpr);
                    break;
            }

            e.Canceled = true;
            DocumentGrid.Rebind();
        }
    }
}

Can someone please tell me what is wrong with this code?

Menu will not load page in specified Target Frame

I am trying to have a RadMenu navigate to a specific page in a specific "frame". Now the frame can be an IFrame or a RadPane, I'm not picky, just needs to work. Is there something obvious here that's preventing it from working?

What's happening is the page is being loaded into a new window.

I am using version 2009.2.821.35

<table width="100%" cellpadding="0" cellspacing="0" border="0">
<

tr>

<td>

<

telerik:RadMenu ID="RadMenu1" runat="server" Skin="Black" Width="1000px" OnItemClick="RadMenu1_ItemClick">

<Items>

<telerik:RadMenuItem runat="server" NavigateUrl="home.aspx" Text="Home" Target="Main">

</telerik:RadMenuItem>

<telerik:RadMenuItem runat="server" NavigateUrl="Portfolio.aspx" Text="Portfolio" Target="Main">

</telerik:RadMenuItem>
</Items>

</

telerik:RadMenu>
</td>
</tr>
<tr>

<td>

</td>

</tr>
</table>

Thanks,

Menu

Rtl rendering problem

Hi,
I'm using the latest official version of ASP.NET Ajax and I use IE8.0.
Please check the following demo :
http://demos.telerik.com/aspnet-ajax/toolbar/examples/functionality/righttoleft/defaultcs.aspx
as you see the controls (RadToolBarDropDown and RadToolBarSplitButton ) has been used to demonstrate the right to left functionality, but they don't render properly.
just change your demo and move the RadToolBarDropDown or RadToolBarSplitButton from the last to the beginning of toolbar and instead of short names like Left,center,Right or Red Blue,Green use longer names.
the if you click on them, you will see that some portion of items the items truncated on the screen.

if you compare it with http://demos.telerik.com/aspnet-ajax/toolbar/examples/functionality/itemtypes/defaultcs.aspx you will find that the starting point of popup menu is wrong, means for this one when you click on RadToolBarDropDown or RadToolBarSplitButton the popup menu starts from left to right ( it aligned from the text portion toward down arrow image which is right) .
For http://demos.telerik.com/aspnet-ajax/toolbar/examples/functionality/righttoleft/defaultcs.aspx example we expect the right behavior ( It should be aligned from the text portion toward the down arrow image) bu as you can see the popup menu always render from left to right ( from down arrow image toward text portion )

Thanks

Grid Drag Drop with datatable using sqldatasource

hi,

I have to reorder items in the radgrid by using drag and drop. A solution provided in exisiting forum thread was using data tables. I can reorder items but this is only temporarily. As all the processing is done in data table. What i want is when my data is updated in data table it should be updated in actual database from where i am getting the data (through sqldatasource). I am using a c# version. Please help in it. I will be very thankful.

Cheers, Ali

Line Graph Connector Lines

Is there a way to selectively draw line graph connector lines? In other words, to draw some lines between data points, and not draw others?

Ajaxrequest only on certain treeview events?

I'm not even sure this is possible, but here it goes...

I have a rad splitter with 3 panes in it (A, B and C). Pane "A" gets a treeview loaded into it dynamically, with handlers assigned to it at runtime, etc during the pageload. Pane "B" has a panel in it that loads user controls based on which node in the treeview you click.

I add at runtime the ajax setting to update the panel in pane "B" when the tree is interacted with, like this:

    
                    RadAjaxManager1.AjaxSettings.AddAjaxSetting(Tree, UPanel) 
        
                    RadAjaxManager1.AjaxSettings.AddAjaxSetting(Tree, Tree)

It's cool and everything works, HOWEVER -

I don't really want to update the Tree every time. I only really want to update it on certain events (like selecting an item from a tree context menu) but not on others (selecting a node), however I do want update the "UPanel" control when I select a node.

How could I implement this? I'm familiar with the RequestStart and RequestEnd handlers of the AjaxManager, but I'm not seeing a clear strategy to get to where I want.

Any suggestions would be appreciated!
