Hello All,

I need to change the control type durring AutoGeneration of a property to a ListBox. In my case, I have an 'int' property which is the primary key in a list table. Since the table changes from time to time, I can't use an Enum type. So how can I change the control type at run-time?

Unable to design RadTreeView in Blend

Hi,

I'm having a problem with setting the RadTreeViewItem's CheckState property through the ItemContainerStyle of the RadTreeView. Specifically, I receive an error message every time I try to edit the xaml in design mode with Blend (versions 3 or 4 RC) and nothing gets rendered on the design surfice. The message is:

"The member 'CheckState' is not recognized or is not accessible."

I managed to reproduce the problem with a stripped-down version of the xaml:

    
            <Window x:Class="WpfApplication18.MainWindow" x:Name="Window" 
        
                    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"   
        
                    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"               
        
                    xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation" 
        
                    mc:Ignorable="d"   
        
                    Width="640" Height="480" 
        
                    xmlns:sys="clr-namespace:System;assembly=mscorlib">  
        
                <Grid>   
        
                    <telerikNavigation:RadTreeView IsOptionElementsEnabled="True">              
        
                        <telerikNavigation:RadTreeView.Items> 
        
                            <sys:String>Item 1</sys:String>               
        
                            <sys:String>Item 2</sys:String>               
        
                            <sys:String>Item 3</sys:String>      
        
                        </telerikNavigation:RadTreeView.Items> 
        
                        <telerikNavigation:RadTreeView.ItemContainerStyle> 
        
                            <Style TargetType="{x:Type telerikNavigation:RadTreeViewItem}">  
        
                                <Setter Property="CheckState" Value="On" />   

                                <Setter Property="OptionType" Value="CheckList" />                   
        
                            </Style> 
        
                        </telerikNavigation:RadTreeView.ItemContainerStyle> 
        
                    </telerikNavigation:RadTreeView>         
        
                </Grid> 
        
            </Window>

It's only the CheckState property that's causing the problem (the OptionType property from the sample works fine).
Sources on the internet suggest tha an internal exception in the property 'setter' might be causing such behavior but that's just a clue.
Do you have any idea how I can get it working in Blend ??

Docking Compass Offset Problem

I have seen the posts about the Compass being displayed incorrectly when DPI is not 100%, so I checked and that is not my problem. This just doesn't seem to me to be a problem that would need to be voted on to get it taken care of. We were almost set to buy the product on Monday, and then I ran into this. Please tell me it will be fixed.

Compass Bug Illustration

Thanks in advance,
Steve

PS - Here's some additional information. Apparently the control does not consider having the Windows 7 taskbar on the left of the screen, so on my main monitor, not only is it offset from the top, but also from the right. Both my monitors are set at 1920x1080.

RadGridView smooth scrolling

Does anyone know of an example of how to do smooth scrolling similiar to the Xceed grid with the RadGridView.

Basically what they do is allow you to sort filter and group without paging and just with the scroll bar. Say you have 1 million records you can scroll through them without hitting the database for all the data. It just gets the 200 at a time, you can set the value as well. All you need to do is give it a Iqueryable and it does the rest.

Can you do this with the RadGridView?
