RadTreeView Ajax as Master for Master-Detail is slow

Hi Gurus,

I'm using a RadTreeView to pick an item from a list of hierarchical data and I want to display details for that item in a DetailsView control.

I have it woking, but it is VERY slow. After the user clicks on an item it takes quite a long time (relatively) to populate the DetailsView via AJAX.

I tested with a DropDownList control and it is very quick. The DetailsView loads really fast.

I'm thinking maybe I'm doing something wrong with your RadTreeView so maybe you can help me out?

Here are the details...

I set up the RadTreeView with an OnNodeClick event like so...

    
                <telerik:RadTreeView ID="RadTreeView1" Runat="server"   
        
                    DataSourceID="SqlDataSource1" 
        
                    DataFieldID="ServiceLineID" 
        
                    DataFieldParentID="ParentID" 
        
                    DataTextField="ServiceLineName" 
        
                    DataValueField="ServiceLineID" 
        
                    OnNodeClick"RadTreeView1_NodeClick"> 
        
                </telerik:RadTreeView>

I have a Master Page so I'm using a RadAjaxManagerProxy like so...

    
                <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadTreeView1">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="DetailsView1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                        <telerik:AjaxSetting AjaxControlID="DetailsView1">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="DetailsView1" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadTreeView1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManagerProxy>

Any ideas how I can improve ajax performance here? I'd rather not have to cascade drop-down lists for this hierarchical data.

Thanks in advance.

NodeClick not fired

Hello All,

I've found out (the hard way) that NodeClick event is not raised when the page containing the treeview has EnableViewState = false.
Is this a bug? I think it migth be since other events like NodeDataBound and ContextMenuItemClick are raise normally.

Thanks,

Martín

Scheduler fill 100% height

I'm having a problem in a scenario similar to your demo seen here:

http://www.telerik.com/demos/aspnet/prometheus/Scheduler/Examples/BlackPearl/DefaultCS.aspx

where the scheduler does not want to fill up 100% of the height of the specified pane/browser window. It handles width just fine, but will not fill remaining space at the bottom. I have tried just about every solution I could find here on the forums and in the documentation to no avail.

Any help would be greatly appreciated!

Button in appointment to open modalpopup

Just looking to evaluate the scheduler and got a couple of issues:

I've got a standard customer search modalpopup and also a standalone customer search that I use in my application to allocate customers to orders, diary entries, events etc that I would also like to use in the scheduler.

If I put a custom resource of Customer Name and Customer Account on the appointment screen can I then put a button on the appointment that will open up my modalpopup screen, do my search and then return to the values to the appointment?

Alternatively is it possible to have the button on the appointment do a save ,browse to the seperate search screen then once selected a customer return to the scheduler screen and automatically open the appointment on page_load and populate the details?

Paging problem in hierarchial grid

Hi,

I'm using a rad hierarchial grid (Q1 2008), in which i'm using paging. The page size is set as shown in the snippet below:

<telerik:RadGrid runat="server" ID="radLinks" AutoGenerateColumns="false" Width="100%" AllowPaging="true" PageSize="3" >
<PagerStyle Mode="NumericPages" />

But in the child grid, paging shows erratic behavior. Suppose there are 4 records in the child grid. Then sometimes the first page shows only 1 record, the second page shows 1 more, and the last page shows the remaining 2 records. This behavior changes when I run the application each time.

Once I noticed that even though there were 5 records in the child grid, the 1st page displayed the "No records to display" message, while the 2nd and 3rd page displayed the records properly. How do I get rid of this problem?
