Applying Filter to GridView

Hi,

I am applying a filter programmatically to a Telerik GridView so that only those records which match the selection
should be shown. My predicate seems to be filtering the results correctly but my source collection is never filtered. Here is my
sample code:

//Setting Data Context here

internal void BuildReportObjectCollection()

{

List<ReportObjectEntity> reportObjectCollection =

Presenter.buildReportObjectCollection();

SingleObjectList.DataContext = reportObjectCollection;

}

//Use the list of Guids to filter my collection using
//the predicate here

public void Show(List<Guid> reportObjectList)

{

selectdReportObjectCollection = reportObjectList;

if (selectdReportObjectCollection != null)

{

if (SingleObjectList.ItemsSource != null)

{

// filter

collectionView =

CollectionViewSource.GetDefaultView(SingleObjectList.DataContext);

collectionView.Filter =

new Predicate<object>(FilterForSelectedReportObjectList);

}

public

bool FilterForSelectedReportObjectList(object item)

{

ReportObjectEntity reportObject = item as ReportObjectEntity;

if (reportObject != null && this.selectdReportObjectCollection.Contains(reportObject.ReportObjectID))

{

return true;

}

else

{

return false;

}

}

//The XAML is pretty standard for the GridView, ItemsSource = {Binding}

Does anyone know what is the issue here?

Thanks,

GridView

databinding to ChartArea

Hi,

how can I bind data to ChartArea? It doesnt have SeriesMapping property.

I have a chart that have 3 chart areas. I want to bind the same collection (Observable collection of ViewModels) to these areas, but each area will display different property from ViewModel. Or is making 3 Charts instead of 3 ChartAreas a better approach? (but then i would loose the fancy background).

Second question.. can I save ChartArea to picture or this is possilbe only for charts?

Thanks

Tab tooltip

I am dynamically generating Tab like:
RadTabItem itemToAdd = new RadTabItem()
                    {
                        Header = pnl,
                       ToolTip="RevKey : " + _revKey,
                        Content = newAudit,
                        Padding = new Thickness(10, 5, 10, 5),
                     };

here newaudit is some usercontrol which have agains tabs inside.
So,problem is that I am assigning tooltip="revKey=......" to Top control(itemToAdd ) tab and it show the tooltip to newAudit control tab's also as well as for newaudit tab content (textbox,combox).

Horizontal Scrolling - Filtering Icons dissappear

When i have a few columns at the start of my grid, and i horizontally scroll to the last column, after i've scrolled back to the start, the Filtering icons have vanished from the column headers of the columns that were scrolled out of view.

Before and after shots attached. In between these two screenshots, all i have done is scrolled to the right, and then returned back.

I'm using the WPF Q3 Beta 2, not sure if this issue existed before then.

Mapping needed between the Silverlight and WPF controls

Hi,
I am new to Telerik WPF Controls,
I need to convert some Silverlight stuff to WPF.
I heard that "All the classes or controls in Silverlight has equal classes or controls in WPF".
But when i am trying to do it,i was not able to find some similar controls for WPF.

I will be greatfull if i get a mapping between the Silverlight and WPF controls.

For Eg.
(1) In silverlight,<HierarchicalDataTemplate> is in assembly=Telerik.Windows.Controls
but for WPF it is not there, may be due to <HierarchicalDataTemplate>
is present directly in WPF.

(2) in silverlight the folowing code is used what will be the equivalent code in WPF?.

xmlns:radDock="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Docking"

<radDock:RadDocking.DocumentHost>
    <radDock:RadSplitContainer>
        <radDock:RadPaneGroup x:Name="DocumentHostRadPaneGroup">
        </radDock:RadPaneGroup>
    </radDock:RadSplitContainer>
</radDock:RadDocking.DocumentHost>

Drag/drop from a listbox in one window to a target in a another (owner) window

I have a tool window (based on System.Windows.Window) which floats on top of my main window. The tool window has a listbox with items I want to drag to various parts of the main window.

I can initiate a drag operation, but as soon as the mouse gets to the border of the tool window, the drag image gets stuck while the mouse moves on. My targets never receive any QueryDrop events.

This project is being developed using Prism. On the Silverlight side, I have a similar tool list hosted in a RadWindow, and drag/drop works great. I've also tried using RadWindow on the WPF side, but I still have the same problem.

This is the trial version of Telerik.Windows.Controls.dll - Version 2009.2.724.1020

Thanks for you help!
