Title disappears when Radpane is using Header and Title Template

Hello,
When we use template to decorate the Title/Header and its working fine as long as the pane doesn't gets detached. The moment the radpane gets detached manually, the title/header disappears. Radpane's are loading dynamically through the config file arrangements. The header template is defined in the resource file and leveraged using properties defined.

Your help is highly appreciated!
Thanks in advance!

I can't find where to style the "smallcontent" scrollbar

Hi,

I'm trying to style the scroll bar that allows the user to scroll through the "smallcontent" tiles. There's a scrollview within the LargeContent tile view and that one picks up the general Scrollbar style properly. How can I access the scrollbar (marked as "Not picking up style" in the attached image) style?

I added a screen shot showing the styled scrollbar and the one I can't style.

Thanks,

Joel

how to reverse the y axis values

This is probably simple to do I just can't find it in the help.

I want my y axis values to range from largest to smallest instead of small to large. This should display the bar with the lowest number as the longest bar and the bar in the chart with the highest number as the shortest bar in the chart.

Thank You,
Mark

Prism load view in documenthost (region) problem

Hi everyone,

I'm using PRISM with MEF for modularity with RadDocking Telerik component to display my views into dock.

On my application, I have a Shell with a dockmenu on the left, and a documenthost on the center, here is the Shell.xaml :

<telerik:RadDocking PreviewClose="RadDocking_PreviewClose" x:Name="dock">

<telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer >

<telerik:RadPaneGroup prism:RegionManager.RegionName="{x:Static const:RegionConstants.CentralRegionName}" x:Name="centralGroup" />

</telerik:RadSplitContainer>

</telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer x:Name="leftContainer" InitialPosition="DockedLeft">

<telerik:RadPaneGroup x:Name="MenuGroup">

<telerik:RadPane x:Name="MenuPanel" Header="Menu" CanUserClose="False">

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="*" />

</Grid.RowDefinitions>

<telerik:RadTreeView x:Name="principalMenuTreeView" Grid.Row="1"

VerticalAlignment="Stretch"

IsLineEnabled="True" ScrollViewer.HorizontalScrollBarVisibility="Auto"

SelectionMode="Single" IsEditable="False" IsDragDropEnabled="True">

<telerik:RadTreeViewItem Header="Monitoring" IsExpanded="True">

<telerik:RadTreeViewItem Header="All Customers"

Command="{Binding LoadViewCommand}"

CommandParameter="{x:Static const:ViewConstants.AllCustomersView}" />

</telerik:RadTreeViewItem>

</telerik:RadTreeView>

</Grid>

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking>

I'm using a command in my ShellViewModel to add view in the DocumentHost region, it works correctly :

private void DisplayViewCommand(object viewName)

{

IRegion region = this.regionManager.Regions[RegionConstants.CentralRegionName];

object view = null;

switch (viewName as string)

{

case ViewConstants.AllCustomersView:

view = ServiceLocator.Current.GetInstance<AllCustomersView>();

break;

default:

break;

}

if (region.Views.Contains(view))

{

region.Remove(view);

}

region.Add(view);

region.Activate(view);

}

I overrided the close panel button to remove the view from the Region, it works too (Shell.xaml.cs) :

private void RadDocking_PreviewClose(object sender, StateChangeEventArgs e)

{

if (e.Panes != null && e.Panes.Count() > 0)

{

RadPane toDelete = e.Panes.FirstOrDefault();

IRegion mainRegion = this.regionManager.Regions[RegionConstants.CentralRegionName];

if (mainRegion.Views.Contains(toDelete))

{

mainRegion.Remove(toDelete);

}

e.Handled = true;

}

But, when I drag this pane out of that group (to make it float), and I try to launch the command to load the view again, it prompt me an error in the RadPaneGroupRegionAdapter.cs, on the line "regionTarget.Items.Add(view);" :

Element already has a logical parent. It must be detached from the old parent before it is attached to a new one.

case NotifyCollectionChangedAction.Reset:

regionTarget

.EnumeratePanes()

.ToList()

.ForEach(p => p.RemoveFromParent());

foreach (object view in region.Views)

{

regionTarget.Items.Add(view); /!\ On this line, the exception occurs

}

break;

Maybe I forgot something ?
In advance, thanks for your help.

Regards,
Guillaume

Prism - drag pane out of region

HI

I've cobbled together a custom region adapter from reading lots of threads on here, and everything works fine.

However, I've come up against a problem that I'm sure someone must've seen.

The regions are set on a RadPaneGroup level. You add your view to a specific region and everything's great.

If the user then drags this pane out of that group, then the view is no longer in that region. If they make the view floating, then it's no longer in any defined region - so how so I remove it using the RegionManager?

Any thoughs appreciated!

WPF GridView DisplayOrder

I have a GridView, it supports drag and drop to reorder the rows. It is bound to a custom object. When the user updates the grid and saves it I would like to save the Row's Index to a property on the object called DisplayOrder. Is it possible to bind the RowIndex to the DisplayOrder Property on the object that is the DataContext for the grid?
