Copying of appointments, and missing resources on the server side

Hi everybody!

What I need to do is to be able to copy an appointment in the scheduler, using drag and drop.

I've created a very simple JS function to do that. It should make a copy of the dragged appointment and insert it in the scheduler, and by not calling the eventArgs.set_cancel(true) the initial appointment would be updated to the new timeslot:

    
            function RadScheduler_ClientAppointmentMoveEnd(sender, args) { 
        
                    var Appointment = args.get_appointment(); 
        
                    sender.insertAppointment(Appointment); 
        
                }

The problem is that the resources of the appointment are not sent together with the appointment back to the server, and when I'm trying to access a resource in my custom provider:

    
            public override void Insert(RadScheduler owner, Appointment appointmentToInsert) 
        
            { 
        
            //some other code here 
        
            int TaskID = (int)appointmentToInsert.Resources.GetResourceByType("Task").Key; 
        
            }

I'm getting a NullReferenceException.

On the client side I've checked the properties of the appointment before inserting it and it does indeed hold the resources.
On the server however, the resources seem to disapperar, although the other properties are sent correctly.

How should I solve this problem?

Thanks,
Stefan

get reference to radgrid inside another radgrid

Here is what I have:
I have a radgrid and in one of its column I show another radgrid. Parent(StudentsGrid) and Child(AttendanceGrid). For each student record there can be more than one attendance. I provide a checkbox in attendancegrid so the user can delete a particular attendance. I would like to get the selected attendance records. below is the code that I have until now. I would like to do this on client side not on server side.

pls let me know how to solve this.

function rowSelected() {

var grid = $find("<%= rgStudents.ClientID %>");

var masterTable = grid.get_masterTableView();

var rows = masterTable.get_dataItems();

for (var i = 0; i < rows.length; i++) {
var cell = masterTable.getCellByColumnUniqueName(rows[i], "Attendance");

// how to get the reference to attendance radgrid and loop through its checked items????
}

How to prevent a RadDock being dragged out of a div

I am attempting to prevent a RadDock from being dragged outside of a div containing three RadDockZones. The reason I am trying to do so is that I want RadDocks to be confined to a particular region on the page without being able to drag off that region.

The PortalSite demo shows that the current implementation doesn't prevent you from dragging RadDocks into infinity off the right and bottom hand of your page, allowing the user to scroll well beyond the page. If the dock could be confined to a div area then this could be prevented and could also be useful for other scenarios, though I would accept not being able to drag the docks infinitely off the page as Google IG does.

I assume confining the docks is a question of constantly evaluating the div's position on the OnClientDockPositionChanging event and if the area of the dock is outside the boundary of the current div's positioning, then we'd have to find a way to prevent the position change without exiting the drag, but this would likely greatly affect performance.

DataRowView does not contain a property with the name "Name"

Hi,

I have just updated to the Q1 2008 release of both ASP.NET Ajax and ASP.Net toolset. I am going through a number of pages trying to update existing ASP.NET controls to ASP.NET Ajax controls and have succeeded with most, but the ComboBox is giving me a problem.

I have an Object datasource on a page (called dsProfession) which returns a simple datatable, and the ASP.NET combobox was linked to this OK. When I change to ASP.NET Ajax combobox it does not like me just putting in the columns names from the Object datasource as it seems to want to validate them.

Is there any work around for this other than manually assigning the values when the page is opened?

The definition of the Combobox is:

    
            <telerik:RadComboBox ID="ddlProfession" runat="server"   
        
            AppendDataBoundItems="True" DataSourceID="dsProfession"   
        
            DataTextField="Name" DataValueField="GroupRef"   
        
            MarkFirstMatch="True" Skin="WindowsXP" Width="200px"   
        
            AutoPostBack="True"   
        
            ToolTip="Select a Profession for the fee quote line from the drop down list">  
        
            <Items> 
        
               <telerik:RadComboBoxItem runat="server" Text="NONE" Value="-NONE-" /> 
        
            </Items> 
        
            </telerik:RadComboBox>

and the definition for the Object datasource is:

    
            <asp:ObjectDataSource ID="dsProfession" runat="server"   
        
            SelectMethod="ListGroup" TypeName="dbGroup2  
        
            CacheDuration="1800"   
        
            OldValuesParameterFormatString="original_{0}">  
        
            <SelectParameters> 
        
             <asp:Parameter DefaultValue="false" Name="ShowArchived" Type="Boolean" /> 
        
            </SelectParameters> 
        
            </asp:ObjectDataSource>

[Solved] Text value of RadTimePicker control

Hi!

Just a simple question. How do I get the text value of a RadTimePicker control in the code behind? I have searched for it but can't seem to find it. There is a DateInput.Text property but that doesn't show the text written. I must be able to distinguish between an empty control and an invalid one. So, if someone for example writes "xyz" into the control, where do I find this value?

Thanks!

embedded video not working?

Hi,

I encountered a problem when i tried to embed video with the radeditor: the video wont play. So i tried the same with the demo project here: http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx (used the RadNavigation.avi video) but it does not work there either. both in the dialog as in the editor in preview mode.

Tried several computers, IE 6 ,7 and 8.

Video plays fine when opened manually, so its not a codec problem.

I just selected a video and inserted it, did not change any settings.

Anyone know whats going on and how to fix this?
