Having some problems with my MVVM Application.
So the scenario is the following:
In my MainWindow.xaml, I have a ContentControl placed in a Grid Column, its content is bind to the CurrentViewModel which will be rendered to the appropriate View (in this case, Overview.xaml).
<ContentControl Grid.Row="1" Grid.Column="1" Content="{Binding CurrentViewModel}">
Within this particular view (Overview.xaml) there are multiple UserControls placed within a StackPanel.
<ScrollViewer CanContentScroll="True" VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Visible">
<StackPanel CanVerticallyScroll="True" CanHorizontallyScroll="True">
<views:DiagramView DataContext="{Binding Path=DiagramViewModel, Source={StaticResource Locator}}" />
<views:IncomeCollectionView DataContext="{Binding Path=IncomesViewModel, Source={StaticResource Locator}}" />
<views:ExpenseCollectionView DataContext="{Binding Path=ExpensesViewModel, Source={StaticResource Locator}}" />
<views:CheckCollectionView DataContext="{Binding Path=ChecksViewModel, Source={StaticResource Locator}}" />
<views:BalanceCollectionView DataContext="{Binding Path=BalancesViewModel, Source={StaticResource Locator}}" />
<views:VacationCollectionView DataContext="{Binding Path=VacationsViewModel, Source={StaticResource Locator}}" />
<views:KHCollectionView DataContext="{Binding Path=KhViewModel, Source={StaticResource Locator}}" />
<views:OctaviaCollectionView DataContext="{Binding Path=OctaviaViewModel, Source={StaticResource Locator}}" />
</StackPanel>
</ScrollViewer>
Each UserControl within this StackPanel has a very similar look (obviously there are more stuff in the XAML). There is no constant value regarding Width or Height within my application.
<ListView ItemsSource="{Binding Source={StaticResource groupedCollection}}" SelectedItem="{Binding CurrentItem}">
<ListView.GroupStyle>
<GroupStyle>
<GroupStyle.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding Items[0].CurrentCategory}" />
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
</ListView.GroupStyle>
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="12" Rows="1" />
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemContainerStyle>
<Style>
<Setter Property="Grid.Column" Value="{Binding GeneratedColumn}"/>
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding EncryptedAmount}" />
<StackPanel Orientation="Horizontal">
<TextBlock Text="Got paid on " />
<TextBlock Text="{Binding Date}" />
</StackPanel>
<Button Content="details"
Command="{Binding Path=DataContext.ShowDialogCommand,
RelativeSource={RelativeSource AncestorType={x:Type UserControl}}}"
CommandParameter="QuickEdit"/>
<Button Content="remove" Command="{Binding RemoveCommand}" CommandParameter="Income removed." />
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
The problem is that I can't seem to make the vertical scrollviewer work. It is displayed because I make it visible, but it's disabled. Obviously the StackPanel is gonna grow indefintely, but isn't there a way for it to calculate how much space is needed? Because most of the content is just cut off right now.
So I tried to put scrollviewer in every possible place, but they're all disabled.
<Style TargetType="{x:Type ContentControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ContentControl">
<ScrollViewer>
<ContentPresenter Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/>
</ScrollViewer>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
So then I tried dropping the StackPanel implementation and tried it with a Grid.
Nope, it doesn't work either.
Obviously I'm missing some basis solution here, but just can't figure it out.
Any ideas would be appreciated, seems like a very common scenario to be honest.

and where it is used:
why is the listview not resizing itself after resizing the window itself?
<ScrollViewer CanContentScroll="True" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible">
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>

</Grid>
</ScrollViewer>
I tried dropping the StackPanel implementation and tried it with a Grid. Nope, it doesn't work either.
That's almost correct, apart from the last sentence. Using a Grid is half of the answer, because the StackPanel has no functionality to resize its items... you just need to inform the ScrollViewer when to scroll. Take this example:
<ScrollViewer>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="50" />
<RowDefinition Height="50" />
<RowDefinition Height="50" />
<RowDefinition Height="50" />
<RowDefinition Height="50" />
<RowDefinition Height="50" />
<RowDefinition Height="50" />
</Grid.RowDefinitions>
<Rectangle Fill="Cyan" />
<Rectangle Grid.Row="1" Fill="Green" />
<Rectangle Grid.Row="2" Fill="Red" />
<Rectangle Grid.Row="3" Fill="Blue" />
<Rectangle Grid.Row="4" Fill="Orange" />
<Rectangle Grid.Row="5" Fill="Purple" />
<Rectangle Grid.Row="6" Fill="Yellow" />
</Grid>
</ScrollViewer>
This XAML will make the ScrollViewer ScrollBar appear (once the Window.Height is small enough), but if you remove the RowDefinition.Height values (thereby giving each row a proportion of the whole Grid.Height), you'll see your previous situation where no ScrollBar appears.
Now, none of us want to hard code constant values into our UIs, but you can do this using the Auto setting on the RowDefinition.Height properties instead. Unlike these Rectangles, your controls will all have some Height, so your solution is to set each of your Grid.RowDefinitions like this:
<RowDefinition Height="Auto" />
This will provide your controls with as much space as they need within the Grid and therefore (hopefully) they will have more Height together than the ScrollViewer and therefore the ScrollViewer will display its vertical ScrollBar.

Property definition which I want to bind with checkbox but it's not propagating into a user control. If I just set true and false then it works but if I bind then it doesn't work.
Any help would be highly appreciated
I believe the problem here is
<UserControl.DataContext>
<vm:DashboardViewModel/>
</UserControl.DataContext>
because that basically means using a new instance of DashboardViewModel for this particular view, so I would assume that in your code somewhere you are using a different instance of this view model in which changing the value of Status does not really matter.
If the reason is what I think it is and you want to enhance your user comfort while developing XAML files and using this to help the compiler to know the types you can use the d:DataContext something like:
d:DataContext={x:Type vm:DashboardViewModel}
GridSplitter getting stuck after dragging some pixels,and have to reselect the splitter and drag again.
I am using RadTreeView in one column, and ListBox in second column, in which user can select Item from ListBox and Drag it into RadTreeView.
Please find below screenshot for the UI.
I tried to find solution on SO, but not getting any useful answer.

If your StackPanel needs to receive keyboard inputs, it must first receive the keyboard focus.
Then, from MSDN, in order for a StackPanel to receive keyboard focus, it must be focusable (Focusable = true) and visible (IsVisible = true). By default, panels are not focusable, so you need to manually set it to focusable.
<ListBox>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Focusable="True"
MouseDown="mouseDownPanel" KeyDown="keydownonpanel">
</StackPanel>
</DataTemplate>

Heres the GridViews xaml
<GridView Grid.Row="1"
Margin="30"
ItemsSource="{Binding TextControlList}" SelectionMode="None"
HorizontalContentAlignment="Stretch" />
To adjust it, modify the item of HorizontalContentAlignment as Stretch, within the 'ItemContainerStyle' (NOT within the gridview itself).
In list/gridview control, you can modify the way of item placement via this ItemContainerStyle.
<GridView x:Name="yourGridView" .... >
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
</Style>
</GridView.ItemContainerStyle>
</GridView>
Try to use a ListView instead of a GridView
I've been trying to understand Scrollviewers, and thought I'd take a look at Microsoft's template for a Grid App for 8.1, whose content extends off the screen. What's odd is that there doesn't seem to even be a Scrollviewer in the XAML page. Can anyone tell me what is enabling the scrolling?

If we go check out the default GridView template and look for the ItemsPresenter we see it's embedded in a ScrollViewer at the template level. Since now we know there's one there, if we look up towards the top in the Setter declarations we've got some Properties available to us to interact with that ScrollViewer from the GridView itself by seeing;
<Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/>
<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Disabled"/>
<Setter Property="ScrollViewer.HorizontalScrollMode" Value="Enabled" />
<Setter Property="ScrollViewer.IsHorizontalRailEnabled" Value="False" />
<Setter Property="ScrollViewer.VerticalScrollMode" Value="Disabled" />
<Setter Property="ScrollViewer.IsVerticalRailEnabled" Value="False" />
<Setter Property="ScrollViewer.ZoomMode" Value="Disabled" />
<Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="False" />
<Setter Property="ScrollViewer.BringIntoViewOnFocusChange" Value="True" />
So if we wanted that GridView to not scroll anymore we could tell it not to like;
<GridView ScrollViewer.HorizontalScrollBarVisibility="Disabled"/>
since it's set to "Auto" at the template level by default.
That's the thing about templates, sometimes it just takes digging one level deeper. Hope this helps, cheers.
