XMLDataSource, don't want to show root node

I am binding a PanelBar to a XMLDataSource, which works great. Except all XML starts with "root node". Although I do not want the root node shown, I want the "root items" to be the children of the root node. I've tried playing around with it and searching this forum. Anyone have any ideas?

Thanks!

Error Creating Control

I just downloaded the Q1 2009. I uninstalled my eval and installed the Q1 2009. I moved the appropriate DLLs to my project and referenced them. My website runs fine but the design view is having problems finding RadComboboxes, RadSliders, RadGrids and RadDatePickers. The RadTextboxes render fine. I made sure to reference the new Telerik.Web.Design but to no avail. I thought maybe there was some disconnect because of the split of design.dll (and still do) so I drag and dropped a control to see if this would right the wrong but the dropped control also had the error creating control.

The error reads: "Could not load file or assembly 'Telerik.Web.UI, Version=2009.1.311.35, Culture=...' or one of its dependencies..." Which tells me that it's looking in the wrong DLL it should be looking in Telerik.Web.Design. I don't know how to tell it where to look though. Are the RadTextBoxes still rendered (Design) from the Telerik.Web.UI?

Thanks,
Doug

Derived Columns

If I have a data source delivering columns A, B and C and I want to have the grid display two columns, the first with the contents of A and the second with some function of B & C (assume not achievable via plain SQL), do I have to create invisible gridboundcolumns for B & C and a new gridboundcolumn D and then set D = fn(B,C) etc in the grid's ItemDataBound event? Is this better than referencing the underlying data set in that event? Can anyone point me at some examples of this?

Thanks,
M

Bug in Online Documtation Viewer: Can't Expand Deep Topics

Hi,

I don't know if this is a problem specific to the RadGrid documentation or a problem with the viewer in general but I can't get to a topic 5 levels deep.

Start with this page:
http://www.telerik.com/help/aspnet-ajax/grdbindablepropertytypes.html

And then try to open "Understanding Databinding" then try opening "Telerik RadGrid Binding basics" I'm unable to pull this page up on IE and FF.

Let me know if you need any more info to reproduce the problem.

Thanks,
Jeff

TimeLineView doesn't draw events

I'm following the online example of RadScheduler Timelineview http://demos.telerik.com/aspnet-ajax/scheduler/examples/timelineview/defaultcs.aspx

I'm using the version RadControls for ASPNET AJAX Q1 2009

I've created two sqldatasources, one for the events and other for the resources.

The sqldatasurces have been tested and I get the data OK. To ensure it I bind then to a grid and a dropdownlist and everything seems to be OK.

                            <asp:SqlDataSource ID="SqlOcupacion" runat="server" ConnectionString="<%$ ConnectionStrings:iTurnosConnectionString1 %>" SelectCommand="sp_InternacionTurnos_ShowOS" SelectCommandType="StoredProcedure">         
                        <SelectParameters>         
                            <asp:SessionParameter Name="pIdObraSocial" SessionField="pIdObraSocial" Type="Int32" />         
                            <asp:SessionParameter Name="pfdesde" SessionField="pfdesde" Type="DateTime" />         
                            <asp:SessionParameter Name="pfhasta" SessionField="pfhasta" Type="DateTime" />         
                        </SelectParameters>         
                    </asp:SqlDataSource>                
                    <asp:SqlDataSource ID="SqlRecursos" runat="server" ConnectionString="<%$ ConnectionStrings:iTurnosConnectionString1 %>" SelectCommand="sp_InternacionRecursos_Show" SelectCommandType="StoredProcedure">         
                        <SelectParameters>         
                            <asp:SessionParameter DefaultValue="" Name="IdInstitucion" SessionField="IdInstitucion"         
                                Type="Int32" />         
                            <asp:SessionParameter DefaultValue="" Name="IdInternacionEspecialidad" SessionField="IdInternacionEspecialidad"         
                                Type="Int32" />         
                            <asp:Parameter DefaultValue="1" Name="IdInternacionRecurso" Type="Int32" />         
                        </SelectParameters>         
                    </asp:SqlDataSource>           

The sqldatasources use as parameters SessionFields. I set then in the Page_Load event of my page.

Here is the code of my RadScheduler

                                <telerik:RadScheduler runat="server" ID="SchOcupacionCamas" SelectedView="TimelineView"         
                            GroupBy="Camas" GroupingDirection="Vertical" SelectedDate="2008-05-27" DayStartTime="00:00:00"         
                            DayEndTime="23:59:00"  DataSourceID="SqlOcupacion"         
                            DataKeyField="IdInternacionTurno" DataSubjectField="Descripcion" DataStartField="FechaDesde" DataEndField="FechaHasta"         
                            OverflowBehavior="Expand" ShowViewTabs="false" TimelineView-NumberOfSlots="4"          
                            ColumnWidth="250px" Width="100%" Height="433px" WorkDayEndTime="00:00:00" WorkDayStartTime="00:00:00">         
                            <ResourceTypes>         
                                    <telerik:ResourceType KeyField="IdInternacionRecurso" Name="Camas" TextField="Descripcion" ForeignKeyField="IdInternacionRecurso"         
                                    DataSourceID="SqlRecursos" />         
                            </ResourceTypes>         
                            <TimelineView GroupBy="Camas" NumberOfSlots="4" ReadOnly="True" />         
                        </telerik:RadScheduler>         

The scheduler draw the resources in the first columns but it dont paint the events. The SQLProfiler makes me sure I'm getting the correct set off data.

Here a snapshot of the retrieved data for the SqlOcupacion Data Source

SqlOcupacion

Here a snapshot of the retrieved data for the SqlRecursosDataSource

Thanks!!!

Maximum Size Export To Excel

I have a grid and it contains about 1 million line items... I am very happy with the speed of processing when I sort, filter, etc... I have the data cached in a session variable.. and that makes everything run fast.

However, when I try to export to excel, I am getting an

Exception of type 'System.OutOfMemoryException' was thrown.

The actual number of rows is around 800,000.. here is a snapshot of the schema for the grid...

Table Schema

What can I do to improve performance? What can I do to make the grid export to excel...

and if there are too many items, what is the maximum size I can export?

I am loading the grid using nettiers... I am on 3.5, controls are the latest build, and running sql 2005

Thanks!

AccessKey - Handle [CONTROL] + [CLICK] Event

I have a RadTreeView control that allows users to make multiple selections. I'd like to handle the [CONTROL] + [CLICK] event either server or client side to enable other controls when multiple items are selected in the TreeView. Is this possible?

Cannot type in other fields if Editor is not visible

I have a page that has a RadEditor and an update button wrapped in a RadAjaxPanel. When the update button is clicked the page performs a partial postback and the text in the RadEditor is saved and the RadEditor's visibility is set to false. If the RadEditor content area has focus when the update button is clicked, then no other controls can receive focus.

Please let me know if there is a workaround so that the no longer visible RadEditor does not hijack the browser's focus. Note: I am using IE8, tried it in both IE7 and IE8 compatibility modes. FireFox does not have the issue.

If you'd like, I can post a simple aspx page that reproduces the issue. Thanks in advance.
