Hi

I've been following this example for binding to object data.

However I can't specify the <DataTemplate>.

Instead I get the message "Property 'VisualTree' does not support values of type 'DataTemplate'".

What am I doing wrong?

Get list of displayed items

Hello

My WPF RadGridView is bound to a list of business objects using its ItemsSource property. So far we were using the grid's Records property to get all objects that are being displayed after filtering and in the current sort order. In the latest version of the WPF control suite (Q2 2009) mostly everything related to RadGridView.Records (Record and DataRecord class) is marked as obsolete. So how to get the list of displayed items now?

I've already tried CollectionViewSource.GetDefaultView(myGrid.ItemsSource) but this gets the whole list not only the list after filtering.

Thanks for any help

Is the Filtered event not raised on purpose when the Clear Filter button is clicked?

Thanks.

Sorting with custom GridViewRow Template

I have a "hidden" column (made visible for debugging) called "Index" that I am sorting by... When I first load the grid, the grid is loaded in the correct way - but probably because my list of objects is already sorted. I implemented some custom commands attached to buttons inside the GridViewRow Template for moving objects UP or DOWN in the grid. When the Move Up or Move Down buttons are pressed, the items are removed from the list, inserted at the right location and the list's Index properties are corrected for the new order...

BUT The first time I press Move Up or Move Down, the index changes (I see the indexes in the data records change), but the grid doesn't refresh the items. The NEXT time I press either button, the grid resorts but not in a nice way... Items are always in the wrong order.

For example:

Start with these objects in the grid
1 - AAA
2 - BBB
3 - CCC

Move Down for object AAA: Remove object AAA, insert at new spot in list, reindex. Grid shows:
2- AAA
1 - BBB
3 - CCC

Move Down for object AAA: Remove object AAA, insert at new spot in list, reindex. Grid shows:
2 - CCC
1 - AAA
3 - BBB

I may have to put a small sample together but I'm hoping not. Here is how I have my grid defined:

    
                        <telerik:RadGridView x:Name="SettingsGrid" ItemsSource="{Binding ElementName=UC, Path=CurrentTeamProjectList}" ScrollMode="RealTime"  
        
                                                 AutoGenerateColumns="False" ShowGroupPanel="False" IsFilteringAllowed="False" ColumnsWidthMode="Fill" ShowColumnHeaders="False" 
        
                                                 CanUserFreezeColumns="False" CanUserReorderColumns="False" CanUserSortColumns="False" VerticalGridlinesVisibility="Hidden" 
        
                                                 Margin="4,2,4,2" Loaded="SettingsGrid_Loaded"> 
        
                            <telerik:RadGridView.Columns> 
        
                                <telerik:GridViewDataColumn UniqueName="Index" IsReadOnly="True" DataType="{x:Type System:Int32}"/> 
        
                                <telerik:GridViewDataColumn UniqueName="Name" IsReadOnly="True" DataType="{x:Type System:String}"/> 
        
                                <telerik:GridViewDataColumn UniqueName="Boolean1" DataType="{x:Type System:Boolean}"/> 
        
                                <telerik:GridViewDataColumn UniqueName="Boolean2" DataType="{x:Type System:Boolean}"/> 
        
                                <telerik:GridViewDataColumn UniqueName="NumSeconds" DataType="{x:Type System:Int32}"/> 
        
                            </telerik:RadGridView.Columns> 
        
                            <telerik:RadGridView.SortDescriptions> 
        
                                <cm:SortDescription PropertyName="Index" Direction="Ascending" /> 
        
                            </telerik:RadGridView.SortDescriptions> 
        
                        </telerik:RadGridView>

I tried adding a SortDescription object to the SortDescriptions collection in the grid loaded event, but that did the same thing.

Thoughts?

Vertical Scrolling with custom GridViewRow.Template

Hi,

I have implemented a custom GridViewRow Template but the vertical scrolling of the grid is gone... I'm not sure if I turned it off though since there doesn't seem to be any property like "VerticalScrollBarVisibility" to set?

Here is a sample of how I am defining my grid:

    
                        <telerik:RadGridView x:Name="SettingsGrid" ItemsSource="{Binding ElementName=UC, Path=CurrentSettingList}" ScrollMode="RealTime"  
        
                                                 AutoGenerateColumns="False" ShowGroupPanel="False" IsFilteringAllowed="False" ColumnsWidthMode="Fill" ShowColumnHeaders="False" 
        
                                                 CanUserFreezeColumns="False" CanUserReorderColumns="False" CanUserSortColumns="False" VerticalGridlinesVisibility="Hidden" 
        
                                                 Margin="4,2,4,2" Loaded="SettingsGrid_Loaded">

RadGridView for WPF: Changing ContextMenu per Cell Clicked

Hi,
I want to be able to display a different context menu depending on which column cell the user right-clicks on as described on this article for the RadGridView for WinForms:
http://www.telerik.com/support/kb/winforms/gridview/radgridview-custom-context-menu-dependent-on-element-clicked.aspx

I need to be able to do the same in WPF. Is it possible?
Thanks,
Laura

No items until user action

Hello,
I tried to recreating the 'First Look' sample with different objects. The code below is taken from the sample. I have only changed one line there.

    
            public Example() 
        
                    { 
        
                        InitializeComponent(); 
        
                        this.sampleRadCarousel.ItemsSource = DAL.GetCustomers(); 
        
                        this.sampleRadCarousel.Loaded += new RoutedEventHandler(sampleRadCarousel_Loaded); 
        
                    } 
        
                    void sampleRadCarousel_Loaded(object sender, RoutedEventArgs e) 
        
                    { 
        
                        Path path = CreateLinePath(); 
        
                        Telerik.Windows.Controls.RadCarouselPanel panel = this.sampleRadCarousel.FindCarouselPanel(); 
        
                        panel.ItemsPerPage = 7; 
        
                        panel.Path = path; 
        
                    }

The issue I am having is that the carousel does not display items until I move the mouse wheel or move the items in a different way.

The moduleCarousel.FindCarouselPanel().BringDataItemIntoView(customer); does not help. Is there a way to refresh or something ?

Tooltip stays on screen

I have a line chart bound to a collection, the X-Axis has DateTime values. The collection gets a new item added every few seconds, and the chart correctly updates. But if I have a tooltip displaying when the chart updates, that tooltip becomes fixed to the screen, permanently visible, even if I move the application window away, until I close the application.

I'm using the 2009 Q2 controls.

Differences between Free WPF and Paid?

I recently downloaded the free version of the WPF controls. Is there any significant difference between the free version and the version that you can purchase from Telerik?
