Hi, I'm having some problems when trying to insert/edit data using entity framework and telerik. Lets see 3 cases:

1) using an entity very simple without foreign keys: the operations works fine
2) an entity with foreign keys: the edit operation works, but insert causes a 'null reference' error in InitInsert
3) an child entity: only display data works, both editing and inserting don't works.

I've tried using EntityDataSource and direct binding using linq as source of data, but without success.

Do you have some example using entity framework?

The next code works fine with previous version (Q2):

    
            aspx in master page:  
        
            < <telerik:RadWindowManager ID="rwm_master" runat="server" Skin="Vista">  
        
                    <Windows> 
        
                        <telerik:RadWindow ID="wndOcupado" runat="server" Title="Aviso" BorderWidth="1" Modal="true" 
        
                            Animation="None" Behavior="none" VisibleStatusbar="false" VisibleTitlebar="false"

             function Ocupado(blnEstado)  
        
            {  
        
                var oManager = GetRadWindowManager();  
        
                var wnd = oManager.getWindowByName('wndOcupado');  
        
                if (wnd)  
        
                {  
        
                    if (blnEstado)  
        
                        wnd.show();  
        
                    else      
        
                        wnd.hide();  // <----Problem
        
                }  
        
            }  
        
            function OnRequestStart(sender, args)  
        
             {  
        
              Ocupado(true);  
        
             };  
        
             function OnResponseEnd(sender, args)  
        
             {  
        
                Ocupado(false);  
        
             };

After install Q3 the modal window disappears but the previous window is locked (gray color).

"insufficient memory" error when changing opacity in image editor

We have recently upgraded to latest ASP.NET Ajax components because we had noticed some errors in the editor component. In the last version (SP1), the opacity slider worked reverse as expected. A lighter image was saved as a darker one.

In this version, when i try to make a lighter image (less opacity), the slider works OK, but when i try to save the image, i obtain a popup window saying "insuficent memory", crashing the application.

¿Any ideas?

Thanks in advance

Can someone please point me in the right direction so i may know how to pass additional information in the context parameter in the webmethod.

ipone page transition simulation

Iphone page transition simulation
over at componentone the have setup a cool iphone site that does the cool iphone page simulation really well. See http://www.componentone.com/i/#navmark-

My first thought was to use a tabstrip/multipage combination, but after seeing thourgh the examples I'm not so sure.

I was wondering if anyone had done a similar "thing" using telerik's asp.net components!

RadEditor occupying 100% height of a container

Hi,

Is there any way to make RadEditor occupy 100% height of a RadSplitter pane and resize with it (or with the browser window)?

I have RadSplitter (with 3 panes - header pane and footer pane with fixed height and middle pane with RadEditor) set to occupy 100% height/width of a browser window. I want RadEditor to stretch/shrink (fill 100% of the middle pane) when user resizes the window (or RadWindow in which the page is loaded).

Currently, when I set RadEditor to 100% height, the content disappears - I can see only the toolbars.

Could you please provide me any useful solution (and maybe some simple example) to this situation?

Regards,
Piotr

ShowMoreResults/EnableVirtualScrolling issue

Showmoreresults button(The arrow below the dropdown) is displaying value twice in a combobox.
The same issue is present in the following example as well.

http://demos.telerik.com/ASPNET/Prometheus/Combobox/Examples/PopulatingWithData/AutoCompleteSql/DefaultCS.aspx
If we select some value for example 'Berglunds snabbköp' from the dropdown. After clicking on Select button one value is present in the dropdown which is correct. Now if Showmoreresults button is clicked it will display the above value twice in dropdown.

Could you please tell some way of resoving this issue?

Also the EnableVirtualScrolling="true" is not working first time. After clicking on the Showmoreresults button or on writing something in the textbox eventually scroll starts working i.e. is populating data.
Any help would be highly appreciated.
