Error in AppointmentControl.Initialize()

Hi,

I have been working around with the scheduler and now I have somehow provoked the error underneith.
To provoke the error I drag-resize an appointment in week or day view. The Update method in my custom SchedulerProvider is run without a problem and after that the page just displays the error.

Any Idea what I am doing wrong to make it fail in the Telerik.Web.UI.AppointmentControl.Initialize() method?

Server Error in '/' Application.

[Solved] ScriptManager and StyleSheetManager

Quick question.

What are the defaults for OutputCompression, EnableScriptCombine and EnableStyleSheetCombine for these controls and how does debug=false in the config affect the default if at all?

Thanks

[Solved] Making Columns visible onclick event

I have a RadGrid that has two columns that are invisible to begin with.
When I click a button outside the Grid I want the columns to become visible.
I know that there is a property in the grid (e.g. this.RadGrid1.Columns[0].Visible = true;), but the columns still won't show after setting them to visible in the button click event.
The interesting thing is that if I click the "Refresh" button within the Grid after having clicked the external button the columns show up.
I tried this.RadGrid1.Rebind(), but that doesn't do it either. It seems like only the "Refresh" in the Grid itself makes the columns visible.

How do I get the columns to become visible on the button click outside the grid?

This has got to be something fairly obvious, but I just don't see it.

Any help is appreciated.

[Solved] Timeline View One Hour Slot Duration Opens All Day Appointment

I have run into an issue with the timeline view. I set the properties as follows.

                    <TimelineView         
              ColumnHeaderDateFormat="hh:mm"          
              GroupingDirection="Vertical"         
              HeaderDateFormat="hh:mm"         
              NumberOfSlots="33"         
              SlotDuration="01:00:00"         
              StartTime="08:00:00"         
            />         

When I open the Advance Form from one of the empty time slots, it sets the appointment to all day. Does anyone know a way around this? I have tried this using both versions 2008.3.1314.35 and 2009.2.701.35.

[Solved] Deleting recurring appointment through contextmenu

Hello!

I was just wondering why I get a "Deleting a recurring appointment"-box when I use the little X-icon for deleting the recurring appointment in Scheduler / RadScheduler Context Menu , but not when I delete the appointment through the contextmenu? Would it be possible to also display this messagebox?

Thanks in advance,

NestedViewTemplate and MasterTableView relation

Hello guys, i'm pretty new to ASP and telerik's controls.
I have a RagGrid control, that's contains table with data.
When pressing on entity expand's my nested view with 2 tabs, like in "Hierarchy with Templates" demo.
So, i need to establish relation between selected row in MasterTable and my tabs in nestedView.

    
            ...  
        
            <MasterTableView DataSourceID="NewsDataSource" DataKeyNames="ID" ...> 
        
                  <NestedViewTemplate> 
        
                         <ParentTableRelation> 
        
                                <telerik:GridRelationFields DetailKeyField="Author_ID" MasterKeyField="Author_ID" /> 
        
                         </ParentTableRelation> 
        
                                <asp:Panel runat="server" ID="InnerContainer" ...> 
        
                                    <telerik:RadTabStrip runat="server" ID="TabStip1" MultiPageID="Multipage1" SelectedIndex="0">  
        
                                        <Tabs> 
        
                                            <telerik:RadTab runat="server" Text="Author Information" PageViewID="PageView2">  
        
                                            </telerik:RadTab> 
        
                                       ...  
        
                                        </Tabs> 
        
                                    </telerik:RadTabStrip> 
        
                                    <telerik:RadMultiPage runat="server" ID="Multipage1" SelectedIndex="0" RenderSelectedPageOnly="false">  
        
                                       <telerik:RadPageView runat="server" ID="PageView2" Width="460px">  
        
                                       <asp:DetailsView   
        
                                                    ID="DetailsView1" AllowPaging="True" GridLines="None" Width="100%" 
        
                                                    DataSourceID="NestedAuthorInfoDataSOurce" runat="server" DataKeyNames="ID">  
        
                                                    <Fields> 
        
                                     Some fields there  
        
                                                    </Fields> 
        
                                       </asp:DetailsView> 
        
                                                <asp:LinqDataSource ID="NestedAuthorInfoDataSOurce"   
        
                                                    runat="server" ContextTypeName="NewsApp.NewsDataClassesDataContext"   
        
                                                    TableName="authors">  
        
                                                    Where="ID == @Author_ID">  
        
                                                       <WhereParameters> 
        
                                                               <asp:Parameter Name="Author_ID"  Type="Int32" /> 
        
                                                       </WhereParameters> 
        
                                                </asp:LinqDataSource> 
        
                                      </telerik:RadPageView> 

                                   </telerik:RadMultiPage>

                    </NestedViewTemplate>

             MasterViewColumns, MasterviewDatasource, etc...

As i assume ParentTableRelation maps selected Author_ID field from MasterView to NastedView, so i can use Where as shown above.
But i got System.Web.Query.Dynamic.ParseException: Operator "==" incomplete with types "Int32" and "Object" (sound like this, i got this exception on my native language).
Author_ID in news table and ID in author table are both integer and not allows null.

Is it possible to customize the TemplateManager?

I want to extend it to allow the user to save templates. I've seen the example on how to save a template, but I'd like to be able to utilize the same UI for loading/saving templates.

RadEditor 'bottom height' fully expands even when no modules are being used!!

Greetings,

I'm trying to set the height of the bottom toolbar so that it is only the thickness of the default buttons at the bottom. Something like this:
___________________
Design HTML Preview
___________________

However, even when there are no modules declared and the Module Manager button is removed from the editor, I still get something like this:
______________________________________________________________
Design HTML Preview

_______________________________________________________________

What can be done to correct this??

Thanks!
