How to center/stretch textbox or stackpanel inside dockpanel? - wpf

I'm already tired. I've tried all the ways. I need my text to be in the middle.
Before that, I centered the text by creating a separate DockPanel for it. Now I can’t do this because my interface structure is collapsing

There is no point to use DockPanel if you don't set DockPanel.Dock attached property. Move the TextBlock below of the StackPanel and then set DockPanel.Dock="Right" at that StackPanel.

Two groupboxes in dockpanel, how to set resizing (strech & fixed) correctly?

I have a very basic layout, but still not able to get the behaviour I want. Stupid me...
My grid has two columns, dynamic sized column left and fixed sized column right. This is working. Inside the right column I have stackpanel containing two buttons, they follow the window resizing correctly.
Inside the left column I have dockpanel containing two groupboxes, the lower has fixed height and is docked to the bottom. This groupbox follows the window resizing correctly, just like I want.
But I'm not able to get the upper groupbox to fill the upper section of the dockpanel. I can only set its height as fixed or when setting it "Auto" it gets strange height of 23...? I want it to fill the area and follow window resizing. I tried using stackpanel also in this column, but no success.

<ColumnDefinition/>
<ColumnDefinition Width="220"/>
</Grid.ColumnDefinitions>
<DockPanel x:Name="GroupPanel" Grid.Column="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<GroupBox x:Name="AlarmGroup" Header="Alarms" Margin="10" DockPanel.Dock="Top" />
<GroupBox x:Name="LogGroup" Header="Log" Height="188" Margin="10" VerticalAlignment="Bottom" />
</DockPanel>
<StackPanel x:Name="ButtonPanel" Width="190" Grid.Column="1">
<Button x:Name="StartButton" DockPanel.Dock="Right" Width="150" Height="40" VerticalAlignment="Top" Margin="0,20,10,0">Start</Button>
<Button x:Name="StopButton" DockPanel.Dock="Right" Width="150" Height="40" VerticalAlignment="Top" Margin="0,10,10,0">Stop</Button>
</StackPanel>
</Grid>
By default, DockPanel fills its remaining space with its last child.
You've set the AlarmGroup GroupBox as the first child, so it takes up only the space it needs; it's default. The second child has a fixed height, so it does not take up the remainder of the space.
To achieve the layout you are looking for, move LogGroup to be the first child of GroupPanel and set its DockPanel.Dock property to Bottom.
Example
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="220"/>
</Grid.ColumnDefinitions>
<DockPanel x:Name="GroupPanel">
<GroupBox x:Name="LogGroup" Header="Log"
DockPanel.Dock="Bottom"
Height="188" Margin="10"/>
<GroupBox x:Name="AlarmGroup" Header="Alarms"
DockPanel.Dock="Top"
Margin="10"/>
</DockPanel>
<StackPanel x:Name="ButtonPanel"
Width="190"
Grid.Column="1">
<Button x:Name="StartButton"
Width="150" Height="40"
VerticalAlignment="Top"
Margin="0,20,10,0">Start</Button>
<Button x:Name="StopButton"
Width="150" Height="40"
VerticalAlignment="Top"
Margin="0,10,10,0">Stop</Button>

In a DockPanel there is a property LastChildFill set to true by default which means that the last coltrol you put will take all the space. I also changed VerticalAligment="Bottom" to DockPanel.Dock="Bottom"
Depending on the screen size, Log and Alarm screens get smaller equally. I tried to do it by dividing it into partitions in a Grid. Is it enough for you ?

How to align to a control in the same screen?

In XAML, we typically have <Grid> layout which contains different elements. How do I align a control in one cell of grid to a control in a different cell like below?
(This used to be rather common in traditional applications where controls maybe in different group boxes etc but we still want to align them horizontally in one plane)
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0">
<TextBox x:Name="name" Height="50"/>
<Label Content="John"/>
</StackPanel>
<StackPanel Grid.Column ="2">
<RadioButton Content="Option1"/>
</StackPanel>
</Grid>
The result is below which is ugly:
In this case, I just want to option1 to aligned centered with the TextBox (which does have custom height).
I can use margins to bring it to the desired position but that's kind of hard coded and not too WPFish.
Should I use binding to tie them directly? Is there a better way? Another way I can think of is to keep making grids within grids but seems like that will over complicate for this simple thing?
Try putting them both in another Grid or a horizontal StackPanel, and put that in one of the parent Grid cells.
The following did the trick, basically wrap the <RadioButton> around in <Border>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0">
<TextBox x:Name="name" Height="50"/>
<Label Content="John"/>
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Top">
<Border BorderBrush="{x:Null}" Height="50">
<RadioButton Content="Option1" Margin="10,0,0,0" VerticalAlignment="Center"/>
</Border>
</StackPanel>
</Grid>
This answer helped.
Now the result is:
Three variants.
The first - I will supplement #zar: I use size binding instead of explicitly assigning a value to the size.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0">
<TextBox x:Name="name" Height="50"/>
<Label Content="John"/>
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Top">
<Border BorderBrush="{x:Null}" Height="{Binding ActualHeight, ElementName=name, Mode=OneWay}">
<RadioButton Content="Option1" Margin="10,0,0,0" VerticalAlignment="Center"/>
</Border>
</StackPanel>
</Grid>
Second - I am implementing #Mark Feldman proposal: Delete StaskPanel and add lines to the grid.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<TextBox x:Name="name" Height="50"/>
<Label Content="John"
Grid.Row="1"/>
<RadioButton Content="Option1" Margin="10,0,0,0" VerticalAlignment="Center"
Grid.Column="1"/>
</Grid>
The third - analogous to the first, but without the Border.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0">
<TextBox x:Name="name" Height="50"/>
<Label Content="John"/>
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Top">
<RadioButton Content="Option1" Margin="10,0,0,0" VerticalAlignment="Center" VerticalContentAlignment="Center"
Height="{Binding ActualHeight, ElementName=name, Mode=OneWay}"/>
</StackPanel>
</Grid>

Change keyboard focus to a specific control

I have a usercontrol which has several elements at different logical level. By default, keyboard focus goes to logical control at highest level, but I want to focus to switch to some other control which is deep down in logical tree (but all the controls are loaded when this user control is loaded).
The XAML is shown below, when the OverlayContent (a dialog) goes away, I want focus to move to "EigthLevelTB" a TextBox, but by default control goes to "ThridLevelGB". User can tab and navigate to "EigthLevelTB", but they want default focus to be here rather than tabbing.
I have tried setting focus on this EigthLevelTB in UserControl.Loaded, FocuableChanged events, etc. Also I tried setting KeyboardNavigation.TabIndex="0", but nothing is working for me.
Please suggest what could be going wrong here?

Make ComboBox stretch to available space with maxwidth and right-aligned parent

I'm having a problem achieving the layout i want.
This is my code:
<DockPanel DockPanel.Dock="Bottom" HorizontalAlignment="Right" LastChildFill="True">
<Label DockPanel.Dock="Left" Content="Add new:"/>
<Button DockPanel.Dock="Right" Content="Add" VerticalAlignment="Center"/>
<ComboBox VerticalAlignment="Center" MaxWidth="150" HorizontalAlignment="Stretch">
<System:String>Item1</System:String>
<System:String>Item2</System:String>
<System:String>Item3</System:String>
</ComboBox>
</DockPanel>
What I want is to have the three elements aligned to the right, in the order Label, ComboBox, Button. The Label and the button should take as much space as needed, but I want the ComboBox to take as much space as possible up to 150 px.
It kind of works when the DockPanel is not set to HorizontalAlignment=Right.
Any tips/solutions?
Thanks.
Use the RightToLeft setting, like this:
<Grid x:Name="LayoutRoot">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid FlowDirection="RightToLeft">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
<ColumnDefinition MaxWidth="150"></ColumnDefinition>
<ColumnDefinition Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label FlowDirection="LeftToRight" Grid.Column="2" Content="Add new:"/>
<ComboBox FlowDirection="LeftToRight" Grid.Column="1" VerticalAlignment="Center" MaxWidth="150" HorizontalAlignment="Stretch">
<ComboBoxItem>Test</ComboBoxItem>
<ComboBoxItem>Test</ComboBoxItem>
<ComboBoxItem>Test</ComboBoxItem>
</ComboBox>
<Button FlowDirection="LeftToRight" Grid.Column="0" DockPanel.Dock="Right" Content="Add" VerticalAlignment="Center"/>
</Grid>
</Grid>

Grid Splitter problem in WPF

I want a layout like VS 2008. In which I want two columns and second columns is again split into two.
I done that in the xaml mentioned below, but the GridSplitter is not visible vertically ( which split two columns).
I want both the GridSplitters to be resizable. One GridSplitter resizes the Left Hand Pane and Right Hand Pane and another GridSplitter resizes the subgrid's top pane and right pane..
The Second GridSplitter is working through this XAML but I am not able to produce XAML code that Splits the Right hand Pane and Left hand pane..
Pleas Help!!

Change your vertical Splitter to
<GridSplitter Grid.Column="0" Width="5" ResizeDirection="Auto"
Grid.RowSpan="1"
HorizontalAlignment="Right"
VerticalAlignment="Stretch"/>
This will be much better way to use GridSplitter
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="5"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<StackPanel Background="Aqua" Grid.Column="0" >
<TextBlock FontSize="35" Foreground="#58290A"
TextWrapping="Wrap">Left Hand Side</TextBlock>
</StackPanel>
<GridSplitter Grid.Column="1" HorizontalAlignment="Stretch"/>
<Grid Grid.Column="2">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="5" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<ListBox Grid.Row="0" Background="Red">
<ListBoxItem>Hello</ListBoxItem>
<ListBoxItem>World</ListBoxItem>
</ListBox>
<GridSplitter Grid.Row="1" Background="Gray" HorizontalAlignment="Stretch"/>
<ListBox Grid.Row="2" Background="Violet">
<ListBoxItem>Hello</ListBoxItem>
<ListBoxItem>World</ListBoxItem>
</ListBox>
</Grid>
</Grid>
The GridSplitters should probably be on their own row/column in the grid, not sharing a cell with the other controls.
Your gridsplitter is behind the other controls that's why you can't see it. You can either move it to the bottom in your XAML file (so it is added last) or use the Panel.ZIndex attached property. Additionally you have to set the width for the splitter correctly correctly:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<StackPanel Background="Aqua" Grid.Column="0" >
<TextBlock FontSize="35" Foreground="#58290A"
TextWrapping="Wrap">Left Hand Side</TextBlock>
</StackPanel>
<Grid Grid.Column="1">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<ListBox Grid.Row="0" Background="Red">
<ListBoxItem>Hello</ListBoxItem>
<ListBoxItem>World</ListBoxItem>
</ListBox>
<GridSplitter Grid.Row="1" Height="5" Background="Gray"
VerticalAlignment="Top" HorizontalAlignment="Stretch" />
<ListBox Grid.Row="1" Background="Violet" Margin="0,5,0,0">
<ListBoxItem>Hello</ListBoxItem>
<ListBoxItem>World</ListBoxItem>
</ListBox>
</Grid>
<GridSplitter Grid.Column="0" ResizeDirection="Columns"
Grid.RowSpan="1" Width="5"
HorizontalAlignment="Right"/>
</Grid>
I have acheived the functionality, the XAML is mentioned below:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<StackPanel Background="Aqua" Grid.Column="0" >
<TextBlock FontSize="35" Foreground="#58290A"
