I am new to Visual Studio, C#,...
So please bear with me if my Q is naive.

I downloaded WPF control from your website.
Is there a sample program that I can run to test the grid. The example.cs that I see in each control folder is not it (I think).

Please help :(

Hi.
I found something that might not be a bug, but took me some time to find the error in my code, because no error was thrown.

If the UniqueName of OrderId in the XAML below is changed from "OrderID" to "orderid" for instance, the expand-icon will appear on the row for a hierarchy, but when clicked no rows appears below. So it seems as if UniqueName is "half case sensitive".

I do not know if this should be corrected, or if this is proper behavior of the control, but I think that either the expand icon is shown and there is data below, OR no expand icon and no data below.

These are great controls, by the way.
Thanks.

After setting the itemsource of the radcarousel with items. I can't use set the selecteditem with an item I know it's the itemsource collection.

I am using the RadCarouselPanel inside a ListBox and have always set ItemsPerPage to be around 20.  When I decided to lower this to 5 or 10, I get "index was outside the bounds of the array" when clicking on the item in my ListBox.  If I set back to 20, it works again.

This is the stacktrace for the exception:

Hello,

I have problem with binding of multi column tree view with DataSet.
Actually the problem is - when i bind the multi-column treeview in XAML with ObjectDataProvider, treeview shows the data for the 1st treeview item, however, for the rest of all child item it does not show the data.
 
<ObjectDataProvider x:Key="objectData" MethodName="CreateDataSet"
                                ObjectType="{x:Type local:DataModel}"/>

<HierarchicalDataTemplate x:Key="DetailTemplate"
                                      ItemsSource="{Binding Detail-to-Info}"
                                      ItemTemplate="{StaticResource CellTemplate_Name}">               
                    <TextBlock Text="{Binding Detail}"/>
            </HierarchicalDataTemplate>

<HierarchicalDataTemplate x:Key="MasterTemplate"
                                      ItemsSource="{Binding Master-to-Detail}"
                                      ItemTemplate="{StaticResource DetailTemplate}">
                <DockPanel>
                    <ToggleButton x:Name="Expander"
                      Style="{StaticResource ExpandCollapseToggleStyle}"
                      Margin="{Binding Level,Converter={StaticResource LevelToIndentConverter},RelativeSource={RelativeSource AncestorType={x:Type telerik:RadTreeViewItem}}}"
                      IsChecked="{Binding Path=IsExpanded, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadTreeViewItem}}}"
                      ClickMode="Press"/>
                    <TextBlock Text="{Binding Name}" FontWeight="Bold"/>
                </DockPanel>
                <DataTemplate.Triggers>
                    <DataTrigger Binding="{Binding Path=HasItems,RelativeSource={RelativeSource AncestorType={x:Type telerik:RadTreeViewItem}}}"
                     Value="False">
                        <Setter TargetName="Expander" Property="Visibility"    Value="Hidden"/>
                    </DataTrigger>
                </DataTemplate.Triggers>
            </HierarchicalDataTemplate>


<local:RadTreeListView x:Name="treeTest" DataContext="{StaticResource objectData}"
                               ItemsSource="{Binding MasterTable}"
                               ItemTemplate="{StaticResource MasterTemplate}">
            <local:RadTreeListView.Columns>
                <GridViewColumn Header="Component" CellTemplate="{StaticResource MasterTemplate}" />
                <GridViewColumn Header="State on Master" />
                <GridViewColumn Header="State on Backup" />
            </local:RadTreeListView.Columns>
        </local:RadTreeListView>




Please look into it and let me know, where i lacking to achieve the goal.

In my RadCarouselPanel, I want to pick an item, check to see if that's the top most item,, and then if so, do something.  I've tried the SelectionChanged and MouseDown events of my ListBox, but IsSelectedTopItem is always false.

Hi,

I am using RadGrid for WPF. I am binding a Collection Class with out using dataset..

Can anybody help me to do...

Problem Iam Facing : When i define parent filed "GridViewDataColumn", I not able to define child filed "GridViewDataColum"

 

Can I specify spacing between my items?  It would be great if there was something like a PathStop where I can tell the carousel where to display an item.  I can set different ItemsPerPage which do somewhat what I want, but it ultimately doesn't work because I want custom placement of items along my path.

Following your examples, I am trying to set PathStops.  No matter what I do to the PathFraction and Values, I still get the default behavior (center item is biggest, items fade out to the left and right).  I tried setting IsScalingEnabled="True" IsOpacityEnabled="True" on my RadCarouselPanel, but it has no effect.  I also tried setting TopItemPathFraction in the Properties window and I get an unhandled exception "Object reference not set to an instance of an object.".  I also found OverridesDefaultStyle, but that doesn't do anything for me.  Can you help?  

Also, do you have a list of all the properties and what they mean?
