I have 2 textblocks in a parent container and I want ellipse to be shown after second textblock content when container size is reduced.
You can use a grid:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="This is the first TextBlock. " />
<TextBlock Grid.Column="1" Text="This is the second TextBlock. " TextTrimming="CharacterEllipsis" />
</Grid>

When I put a Textbox in a grid column like below
<StackPanel>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" MinWidth="115"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="90"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="hello"/>
<TextBox Grid.Column="1" />
<Button Grid.Column="2" Content="push me"/>
</Grid>
</StackPanel>
I get proper result, i.e. textbox width is get from parent grid
But when I type a long text, the textbox starts exceeding its column and it stops extending after several extra letters
To .Net 4.6.2, I get same result but changing to .Net 4.7.2 the problem is solved i.e. the textbox width is not changing.
My software is compiled .Net 4.0, is there a solution to solve this for lower .net than 4.7.2?
Tried Pavel's first idea: removing stackpanel and adding another grid row in, still not working in .net 4.6.2
Tried Pavel's second idea: making the width of first column "Auto" instead of "1*". This works, the textbox doesn't extend (.net 4.6.2), however I really wanted the first and second column be responsive to resize.
You can solve this be removing the StackPanel and adding RowDefinition to Grid. You can also set TextWrapping="Wrap" for TextBox for wrapping a long text
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="90"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Text="hello" MinWidth="115"/>
<TextBox Grid.Column="1" TextWrapping="Wrap"/>
<Button Grid.Column="2" Content="push me"/>
</Grid>
StackPanel Y dimension is constrained to content, it will be automatically expanded to its content, more details can be found at panels overview
To me this is a bug that Textbox text size can change its parent width (grid width). This is happening in VS2019 .Net 4->4.6.2 but not in and after .Net 4.7.2.
For anybody faces this problem, I found below workaround by defining an invisible grid which contains textblocks. I get the widths of columns and give them to controls placed in a StackPanel.
<some container>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" MinWidth="115"/>
<ColumnDefinition Width="3*" />
<ColumnDefinition MinWidth="90"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="0"/>
</Grid.RowDefinitions>
<TextBlock x:Name="C0" Grid.Column="0" />
<TextBlock x:Name="C1" Grid.Column="1" Margin="5"/>
<TextBlock x:Name="C2" Grid.Column="2" />
</Grid>
<StackPanel Orientation="Horizontal">
<TextBlock Width="{Binding ElementName=C0, Path=ActualWidth }" Text="hello" />
<TextBox Width="{Binding ElementName=C1, Path=ActualWidth }" Margin="5" />
<Button Width="{Binding ElementName=C2, Path=ActualWidth }" Content="push me"/>
</StackPanel>
</some container>
The margin should be the same for column in grid and control in StackPanel (see second column).
I want text in column 3 wrap and have no horizontal scrollbar. Why doesn't this work?
<ItemsControl x:Name="listMessages" ItemsSource="{Binding Messages}" Grid.IsSharedSizeScope="True">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="Column1"/>
<ColumnDefinition Width="Auto" SharedSizeGroup="Column2"/>
<ColumnDefinition Width="*" SharedSizeGroup="Column3"/>
<ColumnDefinition Width="Auto" SharedSizeGroup="Column4"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Text1" />
<TextBlock Grid.Column="1" Text="Text2" />
<TextBlock Grid.Column="2" Text="Very long text that should wrap to the next line, but it doesn't work" TextWrapping="Wrap"/>
<TextBlock Grid.Column="3" Text="Text4" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
Items take more width than is available to ItemsControl. Same problem is with ListBox.
I tried to add ScrollViewer.HorizontalScrollbarVisibility=Disabled both on ItemsControl and Grid, but this doesn't help.
The text will be wrapped if you don't set the SharedSizeGroup property:
<ColumnDefinition Width="*"/>
Text wrapping and shared size groups don't go well together. You may want to specify a fixed MaxWidth for the ColumnDefinition or the TextBlock.
I have a 5 column grid in WPF which displays some dynamic data. Columns 1,2 and 4 are fixed width as they are effectively labels, but 2 and 5 can be of different lengths.
Column 3 should wrap to make sure all content is shown but can expand to a maximum width of 390. But column 5 should remain on a single line. When I resize the window, everything must remain on screen without a horizontal scrollbar. The middle (3rd) column should shrink down to keep the 4th and 5th columns on screen.
Current behaviour: Column 3 will wrap when the contents expand beyond 390, but resizing the window will not cause this column to resize, but will cause column 5 then 4 disappear off screen.
Here's the code so far:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto" />
</Grid.ColumnDefinitions>
<Grid x:Name="ListItemControl"
Grid.Column="0"
MinHeight="50"
Width="auto"
VerticalAlignment="Top">
<Border Background="LightBlue"
Margin="1,0,1,1" />
<Grid VerticalAlignment="Center"
Margin="20,0,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="40" />
<ColumnDefinition Width="130" />
<ColumnDefinition Width="*"
SharedSizeGroup="col2" />
<ColumnDefinition Width="150" />
<ColumnDefinition Width="auto"
SharedSizeGroup="col4" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition MinHeight="50" />
</Grid.RowDefinitions>
<TextBlock Grid.Column="0"
Grid.Row="0"
Margin="0,10,0,10"
Text="Due" />
<TextBlock Grid.Column="1"
Grid.Row="0"
Margin="0,10,10,10"
Text="Some Date" />
<TextBlock Grid.Column="2"
Grid.Row="0"
Margin="0,10,30,10"
Text="There is some potentially long text here. This is a placeholder and should wrap."
TextWrapping="Wrap"
MaxWidth="390" />
<TextBlock Grid.Column="3"
Grid.Row="0"
Margin="0,10,10,10"
Text="Who's responsible" />
<TextBlock Grid.Column="4"
Grid.Row="0"
Margin="0,10,10,10"
Text="Name - could be a very long name" />
</Grid>
</Grid>
</Grid>
Any help greatly appreciated!
Your ListItemControl Grid is inside another Grid with a single column, dont know the reason. Remove that parent Grid and you are done.
In WPF, I simply want to have a 'container' which has 3 textblocks. I would like these 3 textblocks to be sized so they each take up 1/3 of the parent's width. I noticed that the stackpanel sizes the last child automatically, but is there a way to size each child automatically?
Use a Grid or a UniformGrid
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Text="1" Grid.Column="0"/>
<TextBlock Text="2" Grid.Column="1"/>
<TextBlock Text="3" Grid.Column="2"/>
</Grid>
The grid is very common and in every WPF-App used a lot. However also the UniformGrid is very handy but not so well known.
Ok this is what I wish to do.
I have a resizeable window which has 3 controls in same row in flowing order: textBlock, textBox and button.
textBlock and button have dynamic texts. So theirs size depends upon text inside.
Now what I wish to do is that textBox in the middle is always filling up all empty space between textBlock and button.
How do I do that?
I tried with the following code but it doesn't work because of fixed width in 1. and 3. column.
<Grid Margin="0,0,5,0" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="40"/>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="40"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" HorizontalAlignment="Left" Text="Text1"/>
<TextBox Grid.Column="1"/>
<Button Grid.Column="2" Content="Button1" HorizontalAlignment="Center"/>
</Grid>
You can use Auto for the two outer column widths instead of specifying the width
<Grid Margin="0,0,5,0" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Text1" />
<TextBox Grid.Column="1"/>
<Button Grid.Column="2" Content="Button1" />
</Grid>
You probably don't need the HorizontalAlignment in the columns either
