I have a WPF listbox whose items are defined by a Data Template that consists of a horizontally aligned grid which holds a label and button. When the button is clicked, I would like to pass the label text as a parameter. For the CommandParameter, is there a Binding that I can specify to get the text value of the label?
<ListBox.ItemTemplate>
<DataTemplate >
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="114*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1000"/>
<ColumnDefinition Width="100*"/>
<ColumnDefinition Width="200*"/>
</Grid.ColumnDefinitions>
<Label x:Name="JobFileNameLabel" Grid.Column="0" Content="{Binding JobFileName}" HorizontalAlignment="Left" VerticalAlignment="Center" FontSize="36" FontWeight="Bold" Padding="0"/>
<Button Command="{Binding DataContext.PrintJobBtnClickedCommand,RelativeSource={RelativeSource AncestorType=ListBox}}" Grid.Column="1" Content="Print" HorizontalAlignment="Center" Margin="25,19,23,25" VerticalAlignment="Center" Width="150" Height="70" RenderTransformOrigin="0.203,-0.173" FontSize="36" FontWeight="Bold" Padding="0"/>

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.
<Grid>
<Grid.ColumnDefinitions>
<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>
</StackPanel>
</Grid>

Is this working for you ?

<GroupBox x:Name="AlarmGroup" Header="Alarms" Margin="10" DockPanel.Dock="Top" />
</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>
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 ?

In my List view I use a grid to arrange the controls of list view item
here is the code
<ListView.ItemTemplate>
<DataTemplate>
<Border>
<!--<Label Width="Auto" HorizontalAlignment="Stretch" Height="3" Background="LightGray"></Label>-->
<Grid HorizontalAlignment="Stretch" MinWidth="220" >
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="65*"/>
<ColumnDefinition Width="10" />
<ColumnDefinition Width="25*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" HorizontalAlignment="Left" FontWeight="Bold" Text="{Binding Path=Name}"/>
<TextBlock Grid.Row="0" Grid.Column="2" HorizontalAlignment="Right" Text="{Binding PlanDate.DateValue,StringFormat=d}"></TextBlock>
<TextBlock Grid.Row="1" Grid.Column="0" HorizontalAlignment="Left" Text="{Binding Owner}"></TextBlock>
<TextBlock Grid.Row="1" Grid.Column="2" HorizontalAlignment="Right" Text="{Binding ForecastDate.DateValue,StringFormat=d}"></TextBlock>
</Grid>
<!--<Label Width="Auto" HorizontalAlignment="Stretch" Height="3" Background="LightGray"></Label>-->
</Border>
</DataTemplate>
</ListView.ItemTemplate>
Here the text blocks in grid coloumn 2 horizontal alignment is set to right .. still the texblocks are not been placed at the right . Am i doing some mistake here? Please advise
Try adding HorizontalContentAlignment="Stretch" to your ListView (the default value is Left and that's why you see it's not stretched).
You can remove HorizontalAlignment="Stretch" MinWidth="220" in your inner Grid.
I can't figure out why the contents of my TextBox is affecting my grid column widths. I have setup a grid with 3 columns with widths defined as 50, *, 50, as shown below
Now, when in use, the center column will grow/shrink as the text in the TextBox changes, see the 2 examples below. The actual TextBox is not changing size, so I can't understand why in the world the grid is changing. The Grid is inside of a Border inside a UserControl. The UserControl is used as a DataTemplate in a ListBox.
Edit: I've discovered that this issue is related to the UserControl being in a ListBox, see example image below (UserControl in ListBox (circled in red) vs. UserControl Placed on Form (circed in blue). The grid behaves as expected when the UserControl is placed directly on the form. Code for the form is given below.
UserControl XAML:
<Grid ShowGridLines="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="50"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock Text="Name:" Margin="2" />
<TextBox Grid.Column="1" Margin="2" Text="{Binding Name, UpdateSourceTrigger=PropertyChanged}" Grid.ColumnSpan="2" />
<TextBlock Text="Shift:" Grid.Row="1" Margin="2" />
<TextBox Grid.Column="1" Grid.Row="1" Margin="2" Text="{Binding TimeShift, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, FallbackValue=0}" HorizontalContentAlignment="Right" />
<TextBlock Text="s" Grid.Row="1" Grid.Column="2" Margin="2" />
</Grid>

OK, I figured it out, Bruno V you got me thinking it must have something to do with the ListBox. I needed to add this to my ListBox:
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
Not sure why that works, but it does.
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>
Here is is running:
I have an issue I cannot figure out. I hope I can explain things enough.
Basically, I have a usercontrol that I'm looking to use as a sort of in window modal dialog.
<Grid>
<Rectangle Opacity=".75" Fill="White"/>
<Border Width="425" BorderBrush="LightGray" BorderThickness="2" CornerRadius="20,0,20,0" Padding="3">

<TextBox Grid.Row="0" Grid.Column="1" Grid.ColumnSpan="2" Text="{Binding FirstName}" Margin="3"/>
<!-- Last Name -->
<Label Grid.Row="0" Grid.Column="3" Content="Last Name:"/>
<TextBox Grid.Row="0" Grid.Column="4" Grid.ColumnSpan="2" Text="{Binding LastName}" Margin="3"/>
<!-- Address -->
<Label Grid.Row="1" Grid.Column="0" Content="Address:"/>
<TextBox Grid.Row="1" Grid.Column="1" Grid.ColumnSpan="5" Text="{Binding Address}" HorizontalAlignment="Stretch" Margin="3"/>
<!-- City -->
<Label Grid.Row="2" Grid.Column="0" Content="City:"/>
<TextBox Grid.Row="2" Grid.Column="1" Text="{Binding City}" Margin="3"/>
<!-- State -->
<Label Grid.Row="2" Grid.Column="2" Content="State:"/>
<ComboBox Grid.Row="2" Grid.Column="3" ItemsSource="{Binding States}" SelectedValue="{Binding State}" Margin="3"/>
<!-- Zip Code -->
<Label Grid.Row="2" Grid.Column="4" Content="Zip Code:"/>
<TextBox Grid.Row="2" Grid.Column="5" Text="{Binding ZipCode}" Margin="3"/>
<Button Grid.Row="4" Grid.Column="0" Grid.ColumnSpan="6" Width="100" HorizontalAlignment="Center" Content="Save" Command="{Binding SaveCustomerCommand}"/>
</Grid>
</Border>
</Grid>
I also have a resourcedictionary containing a datatemplate to connect this usercontrol to it's viewmodel.
<DataTemplate DataType="{x:Type vm:CreateCustomerViewModel}">
<view:CreateCustomerView/>
</DataTemplate>
Finally, in the main window viewmodel, I create an instance of the control's viewmodel, and in the main window view, I am using an itemscontrol and binding it's itemssource property to the instance of the control's viewmodel.
<ItemsControl Height="600" Grid.Row="0" ItemsSource="{Binding CreateCustomerViewModel}" Grid.RowSpan="2" />
Now, my issue is using the itemscontrol in the main window, I've tried a few different ways, but I cannot get the control to be the height of the window. I'm not sure if I shouldn't be using an itemscontrol, or what I'm doing wrong. Any help is very much appreciated.
ItemsControl is for collections. By default it uses a StackPanel to contain its child elements, which disallows stretching in the stack direction (Vertical by default). For a single item use ContentControl (the base of things like Button and Label) instead:
<ContentControl Height="600" Grid.Row="0" Content="{Binding CreateCustomerViewModel}" Grid.RowSpan="2" />
You could try the following:
Put your ItemsControl in a Grid.
Declare your ItemsControl with VerticalContentAlignment="Stretch".
It shouldn't make any difference because it's the default setting, but declare your ItemsControl with VerticalAlignment="Stretch" and try removing the Height="600".
