Preventing a ToolWindow from fading away when closing

Hi everyone,

I am developing a WPF application at my company.
I use controls from RadControls For WPF Trial Version assemblies including the RadDocking control.
The StyleManager.ApplicationTheme property is set to an instance of SummerTheme.

When the user closes a floating Pane then the containing ToolWindow fades away and disappears as shown on the attached pictures 1.png to 3.png.
I want the ToolWindow to disappear without fading away.
What do I need to do ?

Thank you in advance for your help

RadWindow and BringIntoView

Hello,
I have an application with the following properties:

The application can have multiple main windows.
Each main window contains a RadRibbonView and so inherites from RadRibbonWindow.
In addition, I need to create another main window that doesn't contain a RadRibbonView, and so I used a RadWindow to implement it.

I can create this new window, show it in the taskbar and interact with it.
The problem appears when the window is in background and the user clicks on the button to display it. Normally the window should be bring at the top of all windows. I have tried to call BringIntoView, but it doesn't work. In a standard WPF window, I can call Activate to do the job, but this method is not implemented in RadWindow.

How can I implement this feature?

RadWindow should remove the glowing border when Aero is turned off

When Aero is turned off (theme switched to basic) all the other windows (including standard WPF windows) no longer have the glowing border but Telerik RadWindow still does.

Telerik RadWindow should remove the glowing border as well so this is something that should be addressed by Telerik in my opinion but in the meantime is there a workaround to detect when Aero is turned off and manually remove the RadWindow borders?

Screenshot attached.

RadPane header not multibindable

Hi all,

I'm trying to bind a RadPane its header property to a multibinding with a specific converter on it.
That doesn't seem to work, could someone please explain why?

<code>
<telerik:RadPane>
<telerik:RadPane.Header>
<MultiBinding Converter="{StaticResource StringFormatConverter}" ConverterParameter="{}{0} ({1})">
<Binding Path="{loc:Res Id=SomeHeaderId, Default='Signal explorer', ResourceSet={StaticResource LocalResourceSet}}" />
<Binding Path="{Binding SomeViewModel.SomeProperty}" />
</MultiBinding>
</telerik:RadPane.Header>
</telerik:RadPane>
</code>

Thnx in advance!

Kind regards,
Dwight

DistinctFilter binding

Sorry if this has been discussed, I searched but did not find anything. I have the below code in the code behind of my View, but would like to move it to the viewmodel and use binding to set it. I know how to set everything up except for binding the DistinctFilter. Is this possible? If you need more information, I'll try to provide as much as I can.

private void ChartSelectionBehavior_SelectionChanged(object sender, Telerik.Windows.Controls.ChartView.ChartSelectionChangedEventArgs e)

{

grid.FilterDescriptors.SuspendNotifications();

IColumnFilterDescriptor filter = grid.Columns["Status"].ColumnFilterDescriptor;

filter.SuspendNotifications();

foreach (var point in e.AddedPoints)

{

var value = ((PieChartData)point.DataItem).Label;

filter.DistinctFilter.AddDistinctValue(value);

}

foreach (var point in e.RemovedPoints)

{

var value = ((PieChartData)point.DataItem).Label;

filter.DistinctFilter.RemoveDistinctValue(value);

}

filter.ResumeNotifications();

grid.FilterDescriptors.ResumeNotifications();

}

Grouping on a column with a converter with a Virtual item source

Hey, I'm currently having an issue with grouping not working with a column converter, when bound to a VirtualQueryableCollectionView.
When grouping a column with a converter in its databinding (by dragging the column header over the grouping panel), the values displayed are not the converted values, but the underlying values on my model. What is odd, is that the converted values are displayed in the grid, and all the column filtering (with the distinct value filters) are all working as expected. That is, they are having their values run through a converter.

Here is a sample of our code:

Xaml:

<telerik:RadGridView ItemsSource="{Binding QueryableRiskEvents}" AutoGenerateColumns="False" IsReadOnly="True" ">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding risk_id}" Header="ID"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding equipment_code}" Header="Equipment"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding risk_description}" Header="Description"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding start_date}" Header="Start"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding end_date}" Header="End"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding risk_status, Converter={StaticResource StatIntToString}}" Header="Status"/>

C# (on our viewmodel):

public VirtualQueryableCollectionView QueryableRiskEvents

{

get

{

var query = Repository.Entities.RiskEvents.OrderBy(r => r.start_date);

_queryableRiskEvents = new VirtualQueryableCollectionView(query, typeof(RiskEvent))

{

LoadSize = 10,

};

return _queryableRiskEvents;

}

C# (the converter):

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

return "hello";

}

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

return value;

}

With this simplified example, grouping by our Status column shows the underlying integers, rather than multiple "hello" strings.

I have tried just binding the ItemSource to the IQueryable directly (without wrapping it in the VirtualQueryableCollectionView), and the same problem occurs. However, the grouping works perfectly if bound to an IEnumerable source (but fetches all db results at once).

I'd greatly appreciate any tips on how we can get the expected behaviour working (as it already does with the filtering).

How to disable Animation when RadPanes slide out?

I have RadPaneGroup on the right side of my application window. The PaneGroup contains several RadPanes, that are not pinned by default.

When the user clicks one of these panes the pane appears instantly without enervating animation. Then the user pins the pane. When he unpins it again, the pane slides back to its PaneGroup and "disappears".

The problem is, that when sliding back, there is some animation I cannot impede. I don't want any animation when inning and unpinning my panes, because this lets the application appear slow to the user.

I tried:

<telerik:RadPane Title="Editor" IsPinned="False" CanUserClose="False" Name="EditorPane" telerikAnimation:AnimationManager.IsAnimationEnabled="False">

<controls:Editor x:Name="Editor"/>

</telerik:RadPane>

But still there is some animation when unpinning the pane.

How get I rid of the animation???
