How do I make TextBlock to resize to accomodate only available space in StackPanel?
StackPanel limited to my Grid layout. I just illustrated issue but in my real project it's little more complex, so ideally solution should be simple :)
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="1" Grid.Row="1"
Orientation="Horizontal">
<Button Content="Test" />
<TextBlock Text="Test test" />
<Button Content="Test 2" />
<TextBlock Width="Auto">
Some text that I want to trim with ellipse
</TextBlock>
</StackPanel>
</Grid>
You would better make the StackPanel another Grid:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="200" />
</Grid.ColumnDefinitions>
<Grid Grid.Column="1" Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="1*"/>
</Grid.ColumnDefinitions>
<Button Grid.Column="0" Content="Test" />
<TextBlock Grid.Column="1" Text="Test test" />
<Button Grid.Column="2" Content="Test 2" />
<TextBlock Grid.Column="3" Text="Some text that I want to trim with ellipse"/>
</Grid>
</Grid>
I changed your 'main' grid some because it looks odd having only one row and column (starting at index=0) and setting the StackPanel to Grid.Row="1" and Grid.Column="1"
Proper answer is to use DockPanel instead of StackPanel. Last item in DockPanel will be sized to fit remaining space which is exactly what I needed.

I have defined the following XAML:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="200" />
<ColumnDefinition MinWidth="200" />
<ColumnDefinition MinWidth="500" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" Margin="2,2,5,2">
<GroupBox Header="Computer">
<DockPanel>
<ComboBox MinWidth="100" Name="cmbComputerNames" IsEditable="True" DockPanel.Dock="Left" HorizontalAlignment="Stretch" Width="auto" />
<Button Content="Connect" Name="bConnect" Width="65" HorizontalAlignment="Right" />
</DockPanel>
</GroupBox>
</StackPanel>
<Button Grid.Column="1" Content="Two" Margin="1,2,5,2" />
<Button Grid.Column="2" Content="Three" Margin="1,2,2,2" />
<GridSplitter Height="100" Width="4" Grid.Column="0"/>
<GridSplitter Height="100" Width="4" Grid.Column="1"/>
</Grid>
So, the left grid column is resizable. I want the "Connect" button to remain right-aligned and with same width. The combobox however, should be left-aligned and the width should grow as the column is resized, so the distance to the connect button remains the same.
Doesn't work:
Can anyone tell me how I can achieve that?
Since this is too long for a comment
Replace DockPanel with Grid and try this:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<GroupBox Header="Some text here">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<ComboBox MinWidth="100"/>
<Button Grid.Column="1" Content="A button" Margin="5"/>
</Grid>
</GroupBox>
<GridSplitter Grid.Column="1" Grid.RowSpan="2" ResizeDirection="Columns" ResizeBehavior="PreviousAndNext" Width="10"/>
<Button Content="some button" Grid.Column="2"/>
</Grid>
#Andy, if you could produce an answer then I will delete mine.
I am trying to get the first label and text box to align to the left side of the screen, and the second label and text box to align to the right side of the screen. What am I missing here? The second set of controls will not align to the right.
Thanks in advance!
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>
<StackPanel Orientation="Horizontal" Grid.Column="0">
<StackPanel Orientation="Horizontal">
<Label Content="Active Profile"></Label>
<TextBox Name="activeProfileName" Width="100" Height="20"></TextBox>
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right" >
<Label Content="Create A New Profile"
HorizontalAlignment="Right"></Label>
<TextBox Name="activeProfileNamey"
Width="100" Height="20"
HorizontalAlignment="Right"></TextBox>
</StackPanel>
</StackPanel>
</Grid>
The outter StackPanel is your problem. Use Grid instead. Your question is actually a duplicate of the Aligning controls on both left and right side in a stack panel in WPF
Here is the code with Grid:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" Orientation="Horizontal">
<Label Content="Active Profile"></Label>
<TextBox Name="activeProfileName" Width="100" Height="20"></TextBox>
</StackPanel>
<StackPanel Grid.Column="2" Orientation="Horizontal" HorizontalAlignment="Right" >
<Label Content="Create A New Profile"
HorizontalAlignment="Right"></Label>
<TextBox Name="activeProfileNamey"
Width="100" Height="20"
HorizontalAlignment="Right"></TextBox>
</StackPanel>
</Grid>
</Grid>
In the WPF grid below, the middle column is not 6. Text B is all the way to the right instead of 6 away from Text A. I have tried * instead of Auto for the other columns but the result is the same.
How do I make the middle column 6? Is there a workaround? Why is it happening? Is it intended behaviour or a bug?
I make my grids this way so that I don't have to set a margin on every element.
<ScrollViewer HorizontalScrollBarVisibility="Auto">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="6" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="6" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<TextBlock Grid.ColumnSpan="3" Grid.Column="0" HorizontalAlignment="Left">xxxxxxxxxxxxxxxxxxxxxxxxxxxx</TextBlock>
<TextBlock Grid.Row="2">Text A</TextBlock>
<Rectangle Fill="YellowGreen" Grid.Column="1" Grid.Row="2" HorizontalAlignment="Stretch" />
<TextBlock Grid.Row="2" Grid.Column="2" Background="LightCoral">Text B</TextBlock>
</Grid>
</ScrollViewer>
Note: My window width is Auto.
Edit:
Using #flq's solution but added a scrollviewer with horizontal scrolling, the problem is back. It's probably the same reason as why the solution doesn't show properly in the designer, something to do with WPF not knowing how to calculate widths without a constraining width.
I cannot confirm that setting the third column to * does not work. With the following XAML:
<Grid HorizontalAlignment="Left">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="6" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="6" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<TextBlock Grid.ColumnSpan="3" Grid.Column="0" HorizontalAlignment="Left">xxxxxxxxxxxxxxxxxxxxxxxxxxxx</TextBlock>
<TextBlock Grid.Row="2">Text A</TextBlock>
<Rectangle Fill="YellowGreen" Grid.Column="1" Grid.Row="2" HorizontalAlignment="Stretch" />
<TextBlock Grid.Row="2" Grid.Column="2" Background="LightCoral">Text B</TextBlock>
</Grid>
I get this:
I think you want to use "*" on the other columns that are not a fixed length
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="6" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
How do I make the middle column 6? Is there a workaround?
Solved by setting a MaxWidth inside the ScrollViewer (I used the largest double value).
Why is it happening? Is it intended behaviour or a bug?
In a ScrollViewer (or the designer), there is no maximum width. Somewhere in the layout calculations it is assigning the column width as 6 + *.
I think ultimately it is a bug because the column width can be calculated without needing a max width (it is specified as a fixed value and does not even need to be calculated).
<ScrollViewer HorizontalScrollBarVisibility="Auto">
<Grid MaxWidth="1.79769E308">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="6" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="6" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<TextBlock Grid.ColumnSpan="4">xxxxxxxxxxxxxxxxxxxxxxxxxxxx</TextBlock>
<TextBlock Grid.Row="2">Text A</TextBlock>
<Rectangle Fill="YellowGreen" Grid.Column="1" Grid.Row="2" />
<TextBlock Grid.Row="2" Grid.Column="2" Background="LightCoral">Text B</TextBlock>
</Grid>
</ScrollViewer>
I have the following XAML which shows a textblock in a grid. The problem is that it just stretches out, it even stretches itself greater than the windows width.
<Grid Background="Gray">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Label Grid.Row="1" Grid.Column="0" Padding="0" FontWeight="Bold" Margin="0,0,5,0">Description:</Label>
<TextBlock Grid.Row="1" Grid.Column="1" Text="{Binding Description}" TextWrapping="Wrap" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" />
</Grid>
You need to restrict the width of the second column to make the text wrap -
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
I have a problem regarding a parent grid with a control in it that overlaps a tabcontrol.
I need the child grid (in the tab control) to resize its columns according to the overlapping control.
Specifically, when the overlapping control is resized (due to resize of the window for example) the child grid inside the tabcontrol needs to resize its columns so that the child controls inside the tabcontrol grid isn't overlapped by the control that overlaps the tabcontrol.
I sincerely hope someone here knows a solution for this problem, I've been fighting with it for days :)
Thanks in advance!
Best regards,
Req
edit: In response to the comments below:
Absolutely - I figured I should have, but seeing that I was/am at work I didn't have the code handy. But I can write up a similar example of the XAML.
<Grid Name="parentGrid" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="1*" />
<RowDefinition Height="1*" />
</Grid.RowDefinitions>
<TabControl Name="tabCtrl" Grid.Column="1" Grid.ColumnSpan="2" Grid.Row="1" Grid.RowSpan="2">
<TabItem Name="tabItem1">
<Grid Name="tabCtrlGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" /> <!-- This is the column I want to resize according to the overlapping image control below -->
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="1*" />
</Grid.RowDefinitions>
<Button Name="someChildControl" Grid.Column="1" Grid.Row="0" />
</Grid>
</TabItem>
</TabControl>
<Image Name="overlappingImg" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="0" Grid.RowSpan="2" /> <!-- whenever the screen/window is resized, the parentGrid resizes, and thus resizing this overlapping image. -->
</Grid>
What needs to happen is that column 0 in the tabCtrlGrid needs to resize its width to fit the width of the overlapping area of the image. That way someChildControl is never overlapped by the image, regardless of how it's resized.
Hopefully that makes it a little more clear :)
How does this look?
<Grid Name="parentGrid" Background="LightGray">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100" />
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="100" />
</Grid.ColumnDefinitions>
<Rectangle HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Fill="Aqua"/>
<TextBlock Text="Tab controller" HorizontalAlignment="Stretch" VerticalAlignment="Bottom"/>
<Rectangle Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Fill="Aqua"/>
<TextBlock Text="Up down nav" Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>
<Grid Grid.ColumnSpan="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Rectangle HorizontalAlignment="Left" VerticalAlignment="Top" Width="130" Height="160" Fill="BlanchedAlmond"/>
<TextBlock Text="CoverArt" HorizontalAlignment="Left" VerticalAlignment="Top" Width="130" Height="160"/>
<Rectangle Grid.Column="1" Fill="LightGray" />
<TextBlock Text="Tab content" Grid.Column="1" />
</Grid>
</Grid>
