Controls moving haphazardly when resizing window

I have created a wpf application. The XAML code for the application is below.
The window looks great when its run, however when I try to resize the window the controls moves haphazardly. I want the controls to stay in place like a proper windows application. Also I am new to WPF. Any suggestion would be appreciated.
I have inserted a image of original and resized window.

The direct cause for the wandering TextBoxes and ComboBox is that their VerticalAlignment is set to Center and they are offset back to the top of the row with the use of gigantic bottom marigins.
They are also within the third row of a Grid, and all of the rows' Height is set in a way that makes them scale to the parent container (window) size. The star '*' in Height="8*", Height="17*" etc. results in rows filling the leftover space in their parent aiming for the specified proportions.
The main culprit behind all of this is most likely use of the designer to drag and drop everything into its place, rather than mindful utilization of the various panels/containers that are avaliable in WPF.
At the very least, you should create the initial panel setup by writing the code yourself. It will result in much cleaner and more maintainable code. I recommend using the designer only as a feedback tool in the beginning of your journey with WPF.
This is probably the layout you're looking for:

Also, I would recommend reading the following article about Panels and Containers in WPF https://www.codeproject.com/Articles/140613/WPF-Tutorial-Layout-Panels-Containers-Layout-Trans
Edit: Other than that I advise to avoid setting hard Width and Height for the containers and most of the controls. Also do not fear to nest containers into one another to achieve the desired result. It's much easier to create and work with nested containers than with a mega Grid.

The main problem is in your row/column definitions. By using starred values, you instruct the application to scale the width/height relative to the other columns/rows.
In other words, to make the controls stay where they are when resizing, remove the stars from the ColumnDefinitions / RowDefinitions.

GridSplitter getting stuck after dragging some pixels

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.
Please find below code for the same, Let me know if you require more information for the same.

WPF Window resize "eats" controls width

I have an issue im struggling a day now. Im trying to center some controls into a Grid layout. I have 2 columns and i want half of the controls centered ad the 1st column and other half to the second column
When the window resize some of them get "eaten" on the edges , and i wasent able to identify the issue
Can anyone spot the issue?
<Grid Margin="0,2,0,-2">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
//.......
<ComboBox x:Name="optMenuLeft" Margin="0,271,0,0" VerticalAlignment="Top" Height="26" HorizontalAlignment="Center" Width="170" Grid.RowSpan="2" />
<Label Content="Menu" Margin="141,271,390,0" VerticalAlignment="Top" HorizontalContentAlignment="Right" HorizontalAlignment="Center" Width="69" Grid.RowSpan="2" />
<ComboBox x:Name="optBedOccupancyLeft" VerticalAlignment="Top" Height="26" Grid.RowSpan="2" HorizontalAlignment="Center" Width="170" Margin="0,240,0,0"/>
<Label Content="Bed Occupancy" Margin="0,240,270,0" VerticalAlignment="Top" HorizontalContentAlignment="Right" Grid.RowSpan="2" HorizontalAlignment="Center" Width="94"/>
//.......
<ComboBox Name="optMenuRight" Margin="255,271,175,0" Grid.Column="1" VerticalAlignment="Top" Height="26" HorizontalAlignment="Center" Width="170"/>
<Label Content="Menu" Margin="176,271,353,0" Grid.Column="1" VerticalAlignment="Top" HorizontalContentAlignment="Right" HorizontalAlignment="Center" Width="71"/>
<ComboBox Name="optBedOccupancyRight" Margin="255,240,175,0" Grid.Column="1" VerticalAlignment="Top" Height="26" HorizontalAlignment="Center" Width="170" Grid.RowSpan="2"/>
<Label Content="Bed Occupancy" Grid.Column="1" Margin="0,240,200,0" VerticalAlignment="Top" HorizontalContentAlignment="Right" Grid.RowSpan="2" HorizontalAlignment="Center" Width="94"/>
//.....

The simplest way is to use grids inside grid. The outer grid will split the window into two columns. The inner grids will split the columns into four cells (2x2). Just center the inner grids and it will work like a charm.
<Grid x:Name="LayoutRoot">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid x:Name="LeftColumn" VerticalAlignment="Center" HorizontalAlignment="Center">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<Label Content="Bed Occupancy" />
<ComboBox x:Name="optBedOccupancyLeft" Grid.Column="1" />
<Label Content="Menu" Grid.Row="1"/>
<ComboBox x:Name="optMenuLeft" Grid.Column="1" Grid.Row="1" />
</Grid>
<Grid x:Name="RightColumn" VerticalAlignment="Center" HorizontalAlignment="Center>
<!-- the same as left column -->
</Grid>
</Grid>
Btw, notice, that when you want split some are to equal columns (or rows or both), you can use UniformGrid:
<UniformGrid x:Name="LayoutRoot" Rows="1">
<Grid x:Name="LeftColumn" />
<Grid x:Name="RightColumn" />
</UniformGrid>

There is also more advanced approach that I often use:
Use UniformGrid to define columns. The xaml is smaller and cleaner.
Use HeaderedContentControl to define labels and inputs
Use Grid's SharedSizeScope feature, to make width of label equal: https://msdn.microsoft.com/en-us/library/system.windows.controls.grid.issharedsizescope%28v=vs.110%29.aspx
<UniformGrid x:Name="LayoutRoot" Rows="1">
<StackPanel x:Name="LeftColumn" Grid.IsSharedSizeScope="True"
HorizontalAlignment="Center" VerticalAlignment="Center">
<HeaderedContentControl Header="Bed Occupancy" Style="{StaticResource LabelValueContentControl}">
<ComboBox x:Name="optBedOccupancyLeft" />
</HeaderedContentControl>
<HeaderedContentControl Header="Menu" Style="{StaticResource LabelValueContentControl}" >
<ComboBox x:Name="optMenuLeft" />
</HeaderedContentControl>
</StackPanel>
<StackPanel x:Name="RightColumn" Grid.IsSharedSizeScope="True">
<!-- the same as left column -->
</StackPanel>
</UniformGrid>
The LabelCalueControlStyle is take advantage of shared column size
<Style x:Key="LabelValueContentControl" TargetType="HeaderedContentControl">
<Setter Property="Padding" Value="5" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="HeaderedContentControl">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="LabelValueContentControl.Label" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<ContentPresenter ContentSource="Header"
Margin="{TemplateBinding Padding}"
HorizontalAlignment="Right" />
<ContentPresenter Grid.Column="1" Margin="{TemplateBinding Padding}" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>

WPF datagrid event handle in the edit mode

i found a very decent auto-complete textbox control, it works perfect as i need. but there is only one issue that am trying to resolve that for a month.
it works well in the normal form as auto-complete control, but not working inside the grid.
the issue is when the auto complete pops up we need to double click the item to select. But inside the grid we do double click to enter the Edit mode, int the edit template when the control pops up, on the first click the grid is closing the edit mode, so the control cant handle the doubleclick, any way to byepass the event to control instead of closing the grid edit mode
i have attached a very neat and Ready to run sample to illustrate this issue, it will be helpful if some experts look into it.
Thanks

have no idea why the TextBlock doesn't act the same as the "Name Picker" control but why wont you just replace the Datagrid's TextBlock with the "Name Picker"?

How to make the scrollviewer work in this scenario?

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.
Cheers

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.
