I have a recursively defined user control that needs the following properties:
there are two columns
the first contains a single border around some text
the second column contains a stack of these same type of controls (the recursive part)
if the box in the first column is shorter than the total height of the stacked boxes in the second column, the box should expand to make both columns the same height.
If the total height of the second column is shorter than the box in the first column, then the last item in the second column's stack should expand so they are the same height.
so for example, it might look like this:
Ok, so far what I have done is create a horizontal stack panel where the first item is a dock-panel containing a border and text... the second column is a vertical stack panel bound to a sublist, creating the recursive user control... like this..
<StackPanel Orientation="Horizontal" Background="AliceBlue">
<local:TMRequirementView Requirement="{Binding Baseline}" />
<StackPanel Orientation="Vertical">
<ItemsControl ItemsSource="{Binding Requirements}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<local:TMGridView Baseline="{Binding}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
Where the requirement looks like this:
<DockPanel>
<Border MinHeight="50"
BorderBrush="Black" BorderThickness="2">
<TextBlock Text="{Binding Description}"
TextWrapping="Wrap" Background="Transparent" Height="Auto" />
</Border>
</DockPanel>
Now this works great if the stacked column is taller, but it doesn't work if the first column is taller, and I get gaps. Any idea how to handle this mutual height dependency?
Update:
So by adding a border around the right columns stack panel, I was able to see that the stackpanel actually did receive the min-height changes. However, even though there was room to expand, the children of the stack panel didn't automatically update. If I fix the minheight of the stack panel before hand to something large, the children fill up. What I need to figure out is how to update the chidren's height based on changes to the stack panel's min-height.
I think the Grid in this layout does what you describe. I put it in a DockPanel so that you can see how it resizes. Try typing stuff into the text boxes and watch how it behaves:
<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<DockPanel>
<Grid DockPanel.Dock="Top">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBox AcceptsReturn="True" Grid.Row="0" Grid.Column="0" Grid.RowSpan="3"></TextBox>
<TextBox AcceptsReturn="True" Grid.Row="0" Grid.Column="1"></TextBox>
<TextBox AcceptsReturn="True" Grid.Row="1" Grid.Column="1"></TextBox>
<TextBox AcceptsReturn="True" Grid.Row="2" Grid.Column="1"></TextBox>
</Grid>
<TextBlock/>
</DockPanel>
</Page>
All three rows of the Grid will have the height of a TextBox at a minimum (when you replace the TextBoxes with other elements, you'll need to set minimum heights to keep them from vanishing if they're empty). Since the third row is star-sized, it will size itself to all remaining vertical space left after the first two rows are arranged. So if there's a bunch of content in the first column, the third row in the second column gets taller.
Edit
Actually, there's no reason to even screw around with a Grid in this case: What you're describing is really the behavior of the DockPanel:
<DockPanel>
<DockPanel DockPanel.Dock="Top">
<DockPanel.Resources>
<Style TargetType="Label">
<Setter Property="DockPanel.Dock" Value="Top"/>
<Setter Property="Background" Value="Lavender"/>
<Setter Property="Margin" Value="1"/>
</Style>
</DockPanel.Resources>
<DockPanel LastChildFill="True">
<Label>Foo</Label>
</DockPanel>
<DockPanel LastChildFill="True">
<Label>Foo</Label>
<Label>Bar</Label>
<Label>Baz</Label>
<Label>Bat</Label>
</DockPanel>
</DockPanel>
<Label/>
</DockPanel>

I'm trying to create a side collapsible panel that include StackPanel
For that Tried use Expander like following
<Expander Width="auto" ExpandDirection="Left" HorizontalAlignment="Right">
<Expander.Header>
<Border BorderBrush="Black" BorderThickness="1">
<StackPanel>
<Grid>
</Grid>
</StackPanel>
</Border>
</Expander.Header>
</Expander>
But this is not working properly, can't do the function that I expected.
As Maciek Świszczowski said, you need to properly align your expander and put the contents inside the context section of the expander. Also, assuming you want it to fill the entire left section, I would recommend you use a Grid to hold it all, like so:
Example:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Expander ExpandDirection="Right" HorizontalAlignment="Left">
<Border BorderBrush="Black" BorderThickness="1">
</Border>
</Expander>
</Grid>
Here's what it looks like (I put a blue background and some text in the expander, and just a red stack panel in the second column in order to make it really clear).
Expanded:
Collapsed:
I have a 3 Level Nested ListView binded to the same 3 Level Nested Collection. MainItems are added at the 3rd level.
Unmodified, there are scrollbars on ALL the levels. On item added, I edit the Containing Grid of the ListViewItem to adjust the height dynamically.
I have succeeded on removing the 3rd Level Scroll Bar. However, I want to remove the 2nd Level also, which I can't seem to do.
When I try to adjust the height of the 1st Level ListViewItem, the scrollbars on the 1st Level just disappears but the height is not adjusted at all.
What I want to do is ONLY have the ScrollBar on the 1st Level and scroll from there.
Basically, something like this:
This is my current code:
<Grid x:Name="ParentGrid">
<ListView x:Name="Level1ListView"
ItemsSource="{Binding Path=Level1}">
<ListView.ItemTemplate>
<DataTemplate>
<Grid x:Name="GridLevel1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<ToolKit_Controls:LayoutTransformControl Grid.Column="0">
<ToolKit_Controls:LayoutTransformControl.Transform>
<RotateTransform x:Name="rotateTransform" Angle="270"/>
</ToolKit_Controls:LayoutTransformControl.Transform>
<TextBlock Text="{Binding Path=Level1NameString}" FontSize="32" HorizontalAlignment="Center" />
</ToolKit_Controls:LayoutTransformControl>
<ListView x:Name="Level2ListView"
ItemsSource="{Binding Path=Level2}"
Grid.Column="1"
>
<ListView.ItemTemplate>
<DataTemplate>
<Grid x:Name="GridLevel2">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Border BorderBrush="White" BorderThickness="1" Grid.Row="0"/>
<TextBlock Text='{Binding Path=Level2Name}' Foreground="Black" FontSize="18"
Grid.Row="0"/>
<Grid x:Name="GridLevel3" Width="300" Height="100" Grid.Row="1">
<ListView x:Name="ListView_Level3" IsSwipeEnabled="False"
ManipulationMode="None"
ItemsSource="{Binding Path=Level3DisplayCollection}"
Grid.Column="1">
<ListView.ItemContainerTransitions>
<TransitionCollection>
<EntranceThemeTransition IsStaggeringEnabled="False" />
</TransitionCollection>
</ListView.ItemContainerTransitions>
</ListView>
</Grid>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid Orientation="Horizontal" MaximumRowsOrColumns="1" ></WrapGrid>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
</ListView>
And the important code which changes the height on item added:
var GridLevel1 = TypedAssociatedObject.GetAncestors().Where(a => a.Named("GridLevel1")).FirstOrDefault() as Grid;
//GridLevel1.Height = GridLevel1.ActualHeight + 50;
var GridLevel2 = TypedAssociatedObject.GetAncestors().Where(a => a.Named("GridLevel2")).FirstOrDefault() as Grid;
GridLevel2.Height = GridLevel2.ActualHeight + 50;
var GridLevel3 = TypedAssociatedObject.GetAncestors().Where(a => a.Named("GridLevel3")).FirstOrDefault() as Grid;
GridLevel3.Height = GridLevel3.ActualHeight + 50;
Level 1 is commented out because when I add it, although the 2nd Scroll Bar is removed the ListViewItem height doesn't change, resulting in the UI being wrong and not showing everything. You also notice that the 1st level scrollbar remains the same size:
What I want is to extend the height of Header 1 so that everything still shows and the 1st Level Scrollbar on the right is the one that extends / grows.
Can anyone help point out what I am doing wrong?
Thank you!
Edit: This is a Windows store app.
Set the ItemsPanel to StackPanel in your inner list views. This way you would not need to adjust the height of each item.
Also to hide the scrollbars use ScrollViewer.VerticalScrollBarVisibility="Hidden" on your inner list views.
Have you considered using grouping?
NOTE: This is one of the first time I'm using WPF.
I am trying to align a certain control, let's say a button for now, in the bottom right corner. But when I debug my application, it misses 8 pixels to the bottom and right. I will attach 2 pictures to show you what happens.
How do I keep the button in place?
My XAML code:
<Window x:Class="Plugin_Manager.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Plugin Manager" Height="350" Width="525" Loaded="Window_Loaded_1">
<Grid x:Name="GridMain">
<Button Content="Refresh" Margin="432,288,0,0" VerticalAlignment="Top" HorizontalAlignment="Left" Width="75"/>
<ListView HorizontalAlignment="Left" Height="273" Margin="10,10,0,0" VerticalAlignment="Top" Width="497">
<ListView.View>
<GridView>
<GridViewColumn/>
</GridView>
</ListView.View>
</ListView>
</Grid>
If you choose to use Grid layout you should try to avoid placing objects via Margin. Margin should be used to create buffer around an object, not move it to a specific point in the window. Use the layout manager's power to your advantage!
Here is a Grid example that does what you are looking for.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<ListView Grid.Row="0" />
<Button Grid.Row="1" HorizontalAlignment="Right" Content="Push Me" />
</Grid>
I would also read up on Layout Manager in WPF. There are several; each having its own advantages & disadvantages.
Here is a DockPanel version.
<DockPanel>
<Button DockPanel.Dock="Bottom" HorizontalAlignment="Right" Content="Push Me" />
<ListView />
</DockPanel>
To create your buffer between the button and the window chrome you could do a few different things:
<Grid Margin="10"> will apply a 10 pixel space between all content and the window chrome on all side.
<Grid Margin="0,0,10,10"> would indent all content, but only on the right & bottom.
<Grid Margin="10,0,10,10"> indents all around, except the top (I commonly do this one, with a different margin value).
<Button Margin="0,0,10,10"> would indent only the button from the chrome (this is the direct answer to your comment question).
Replace the Grid above with DockPanel for the second example, or whatever other Layout Manager you are using.
A usability side note: Your confirmation buttons (I'm assuming your button will be an Ok/Cancel type button) should not be indented differently from the rest of your content. All controls that butt up against the right margin should do so at the same point (i.e., you can draw a vertical line down the right side of them all).
So, using your question's example: your button should not be indented 10 pixels to the right while your list box is not. Keeping things lined up will improve the overall look to your application.
(this ends my "usability and look-and-feel is important" side note) :)
<Button VerticalAlignment="Bottom" HorizontalAlignment="Right" Margin="5"/>
Some code example will help. Try using the alignment in xaml for your button as shown below. Ensure that the margins on the button are 0.
<Button Margin="0" HorizontalAlignment="Right" VerticalAlignment="Bottom"/>
Looking at the sample code, it is your margins and the alignment you have that are probably causing that.
Just some pointers that may help. Instead of using large margins to align the controls, I find it much easier to work with Column and Row definitions on the grid. This way you can align your controls using the grid and they will size properly as you resize your window. I attached an example in hopes it helps in your new adventures with WPF!
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="150"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0" Text="Version Date" Margin="3" VerticalAlignment="Center"/>
<TextBlock Grid.Column="0" Grid.Row="1" Text="{Binding DateSubmitted}" Margin="3"/>
<TextBlock Grid.Column="1" Grid.Row="0" Text="Report" Margin="3" VerticalAlignment="Center"/>
<TextBlock Grid.Column="1" Grid.Row="1" Text="{Binding ReportName}" Margin="3"/>
</Grid>
In WPF, Is there a simple way to stop TabItems in a TabControl from being repositioned when the selected TabItem changes? So that clicking on a TabItem would simply display its contents, but not reposition the TabItems as it usually does (by moving the selected TabItem to the bottom row of tabs if it wasn't there already).
Edit: To clarify, I do want the tabs to be displayed in multiple rows, I just don't want the tab headers to be repositioned when a TabItem from a row other than the bottom row is selected. I'd like the collection of headers to remain completely static, but for the contents of that TabItem to still be displayed when its header is clicked.
Thanks!
I know its late but I had to figure this out today so here goes.
Basically you need to create your own control template for the tab control and use a different panel to contain your tab items.
Here is a simplified example using a WrapPanel.
<Style TargetType="TabControl" x:Key="MyTabControl">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabControl">
<Grid SnapsToDevicePixels="true" KeyboardNavigation.TabNavigation="Local" HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<WrapPanel x:Name="HeaderPanel" HorizontalAlignment="Center" VerticalAlignment="Top" IsItemsHost="true"
Grid.Row="0" KeyboardNavigation.TabIndex="1" />
<ContentPresenter Grid.Row="1" x:Name="PART_SelectedContentHost" ContentSource="SelectedContent" Margin="10" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
You then use this as follows
<TabControl Style="{StaticResource MyTabControl}" ....
You can download the control template samples here
If you have Blend you can Edit a copy of the template for your tab control to remove this behavior I believe.
I have a xaml code:
<Grid>
<WrapPanel>
<TextBox ></TextBox>
<Button Content="GetIt" />
</WrapPanel>
</Grid>
How i can to get all available space for textBox?
i want to do something like that:
|[____________________][GetIt]|
There are a number of ways this can be achieved, including this one:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBox />
<Button Grid.Column="1">GetIt</Button>
</Grid>
Try this:
<Grid>
<TextBox HorizontalAlignment="Stretch" Margin="2,2,102,2"></TextBox>
<Button HorizontalAlignment="Right" Width="100" Content="GetIt" />
</Grid>
Just make the button the desired width and the text box will fill up the rest.
Thanks for the catch; corrected above to properly handle margin on right. This does, however, require you to update the margin when the button width changes. Two columns is a better solution if you plan to change the spacing often. Using the margin is cleaner if you have several controls in the grid and don't want to create nested grids to handle this kind of split.
The simplest way is to use a DockPanel instead of a Grid (the default for LastChildFill is true but I also added it here for clarity):
<DockPanel LastChildFill="True">
<Button Content="GetIt" DockPanel.Dock="Right" />
<TextBox ></TextBox>
</DockPanel>
Here's a way to achieve the layout that you're looking for:
<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Page.Resources>
<Style TargetType="TextBox">
<Setter Property="Margin" Value="2"/>
</Style>
</Page.Resources>
<DockPanel>
<DockPanel DockPanel.Dock="Top">
<!-- Because the Button is fixed in size, you can divide the row it's
in using a DockPanel: the Button is docked to the right edge, and the
TextBox fills up the remaining available space. -->
<Button Margin="2" Padding="2" DockPanel.Dock="Right">GetIt</Button>
<TextBox />
</DockPanel>
<!-- Because the TextBoxes *aren't* fixed in size, you can't use docking,
as it won't size them. So put them in a Grid and use star sizing to
divide the grid's vertical space into two equal parts. The Grid will
fill up the remainder of the (outer) DockPanel. -->
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBox Grid.Row="0">Another TextBox</TextBox>
<TextBox Grid.Row="1">Yet another TextBox</TextBox>
</Grid>
</DockPanel>
