In WPF XAML I cannot seem to get the grid columns to take up the remaining space before a GridSplitter element. It's strange as the vertical one is working and seems to have the exact same set up. I have tried a number of things including using Width="*" and HorizontalAlignment="Stretch" on the column definitions and the left panel Grid itself, but nothing seems to allow it to stretch to the first GridSplitter.
Here is an example of what is happening when using the GridSplitter elements to manually resize:
And here is my XAML:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" MinWidth="200"></ColumnDefinition>
<ColumnDefinition Width="4"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<!-- Left Panel -->
<Grid Grid.Column="0" Background="LightSlateGray">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition Height="4"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<!-- Left Panel | Top -->
<Grid Grid.Row="0">
<TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Padding="10 10 10 10">Test</TextBlock>
</Grid>
<!-- Left Panel Grid Splitter -->
<GridSplitter Grid.Row="1" Height="4" HorizontalAlignment="Stretch" Background="LightGray" ></GridSplitter>
<!-- Left Panel | Bottom -->
<Grid Grid.Row="2">
<TextBlock HorizontalAlignment="Center" VerticalAlignment="Center">Test</TextBlock>
</Grid>
</Grid>
<!-- Horizontal Grid Splitter -->
<GridSplitter Grid.Column="1" Height="Auto" Width="4" VerticalAlignment="Stretch" Background="LightGray" ></GridSplitter>
<!-- Right Panel -->
<Grid Grid.Column="2">
<TextBlock HorizontalAlignment="Center" VerticalAlignment="Center">Test</TextBlock>
</Grid>
</Grid>
All I really want is for the first Grid.Column that holds the left panel to resize itself and it's content to cover the remaining space between the left of the window, and the GridSplitter.
Any help would be really appreciated!
Thanks
Your "Horizontal Grid Splitter" needs HorizontalAlignment="Center". Actually any value other than Right - which appears to be the default for GridSplitter - works fine.
You would have the same issue in your inner (vertical) splitter if you set VerticalAlignment to Bottom, but this apparently is not the default value.
WPF layout never ceases to keep us on our toes.

I have the following Grid with a TextBox in it:
<UserControl ...>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="30px"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="1px"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBox Grid.Column="1" Grid.RowSpan="3" AcceptsReturn="True"
TextWrapping="Wrap" HorizontalScrollBarVisibility="Hidden"
VerticalScrollBarVisibility="Visible" HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"/>
<!-- content in other cells of the Grid's first column -->
</Grid>
</UserControl>
I want the TextBox to fill all space that is available on the control (width and height-wise) and should the user enter more text than fits into it I want its vertical scrollbar to become active, without resizing the TextBox. What happens instead is that the size of the TextBox changes to accomodate the content and the whole grid grows with it.
How do I achieve what I need?
Edit: Here's an illustration of what happens.
The above screenshot is of the situation when the content fits comfortably into the TextBox. The below screenshot is of the situation when there is not enough room to fit all content - the TextBox is then resized to fit it and this resizes also the grid that it is placed in, making it look broken.
Edit 2: The project that demonstrates this behavior is here.
I have managed to solve this by adding an invisible Border in the same cells of the Grid as the TextBox, then setting TextBox' Width and Height to ActualWidth and ActualHeight of that Border respectively:
<Border x:Name="b" Grid.Column="1" Grid.RowSpan="3"
HorizontalAlignment="Stretch"/>
<TextBox AcceptsReturn="True" TextWrapping="Wrap" Grid.Column="1"
Grid.RowSpan="3" Width="{Binding ActualWidth, ElementName=b}"
Height="{Binding ActualHeight, ElementName=b}"
HorizontalScrollBarVisibility="Hidden"
VerticalScrollBarVisibility="Visible" HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"/>
This then caused the TextBox to stay of fixed Height regardless of its content, but there was another problem with its Width: it grew when the interface was expanded, but didn't shrink afterwards, because of the underlying ScrollViewer. The trick was to set that ScrollViewer's HorizontalScrollBarVisibility to Disabled, instead of Hidden as I had done previously.
I pushed changes of the example project to GitHub, so the solution is now available here.
The TextBox doesn't fill the Grid. You can confirm this yourself by specifying a Background for the Grid:
<UserControl>
<Grid Background="Yellow">
...
This is because the height of the Grid is 30 px + whatever the height of the TextBox is + 1 px. For the contents of the row 2 or 3 to fill the Grid, you need to change the Height of at least one of the RowDefinitions to *:
<UserControl>
<Grid Background="Yellow">
<Grid.RowDefinitions>
<RowDefinition Height="30px"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
<RowDefinition Height="1px"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBox Grid.Column="1" Grid.RowSpan="3" AcceptsReturn="True"
TextWrapping="Wrap" HorizontalScrollBarVisibility="Hidden"
VerticalScrollBarVisibility="Visible" HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"/>
</Grid>
</UserControl>
I want to have main window split in three parts like the one on the picture. there's supposed to be a line (red one) or left border of the rectangle number 2, that, when it's dragged with mouse, it resizes both rectangle 1 and 2. it's like the behaviour of playlist in windows media player. any ideas on how to obtain this? Also, it would be great if someone proposes a solution to how this playlist make collapsed if the red line is dragged to the right.
Define a <Grid> with columns and rows like so:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="300"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="600"/>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="300"/>
</Grid.ColumnDefinitions>
...
and then the gridsplitter (still inside the grid):
<GridSplitter Grid.Row="0" Grid.Column="1" ResizeDirection="Columns" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>
Note that the gridsplitter will need it's own column.
It is a GridSplitter, here is how to use one:
<GridSplitter Grid.Row="1"
Height="5"
Width="Auto"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Background="Gray"
ResizeDirection="Rows" />
You need to assign a Row or Column to it from your Grid, and specify its ResizeDirection. This one is horizontal, but you get the idea for a vertical one.
HTH,
Bab.
i have a basic grid in my WPF application:
<Grid>
<Grid Height="260" HorizontalAlignment="Left" Margin="24,25,0,0" Name="grid1" VerticalAlignment="Top" Width="452">
<Border BorderBrush="Red" BorderThickness="6"></Border>
</Grid>
</Grid>
the grid is in the middle of the window.
When i maximize the window i want the grid to auto resize itself to the size of the window and stay with the same margin that i specified.
How do i do that ?
Do i have to calculate and resize the whole thing in the resize event?
i get from this:
to This (i dont want this):
i want the grid to resize to the same portions as it was , but for a full screen.
Remove Width and Height.
<Grid>
<Grid Margin="24,25">
<Border BorderBrush="Red" BorderThickness="6"></Border>
</Grid>
</Grid>
e: Added a second grid to make it identical to OP
You could host the Grid inside of another Grid with something like:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="25" />
<RowDefinition />
<RowDefinition Height="25" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="25" />
<ColumnDefinition />
<ColumnDefinition Width="25" />
</Grid.ColumnDefinitions>
<!-- Main Grid -->
<Grid Grid.Row="1" Grid.Column="1">
<!-- Main Content -->
</Grid>
</Grid>
That would allow you to put all your content inside of the Main Grid, while maintaining a constant margin of 25 around all edges.
I have a WPF Line of business application. Most of it is hosted in user controls in tabs.
I'm having an issue finding out how to layout this so it would fit any resolution (with scrolling if necessary).
Here's the issue described in code because i really can't figure out how to put this to text, if it's not clear please let me know i'll try to draw something up.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition> <!--What i actually want to say here isn't "take all remaining space" but "take all remaining space without scrolling,
and then scroll based on everything as if this was auto and no longer *-->
<ColumnDefinition Width="Auto"></ColumnDefinition><!--But what happens for now is that since this is auto , it will not scroll at all untill the * column has fully scrolled-->
</Grid.ColumnDefinitions>
<StackPanel>
<StackPanel Orientation="Horizontal">
<Label></Label>
<TextBox></TextBox>
</StackPanel>
</StackPanel>
<StackPanel Grid.Column="1">
<StackPanel Orientation="Horizontal">
<button> <!-- I want the button's container to be in an auto column , don't
want it to take size away from the fields unless needed but don't
want it to stay visible at the expense of the fields either -->
</StackPanel>
</StackPanel>
<TelerikGrid:RadGridView Grid.Row="1" Grid.ColumnSpan="2">
<TelerikGrid:RadGridView.Columns>
<TelerikGrid:GridViewDataColumn Width="*"/> <!-- This makes my grid take a bajillon kilometers because it itself is in a Grid's column of * size itself in a scrollviewer -->
</TelerikGrid:RadGridView.Columns>
</TelerikGrid:RadGridView>
</Grid>
Hard to tell given I cannot load your GridView control in a Window.
I recommend nesting a layout manager Grid for your controls inside your Grid to create a separation between your controls and the GridView. You also should consider combining all the controls in one StackPanel or other layout manager.
Regardless, this layout gives you separation between the controls and the GridView regardless of your choice of layout manager with no need to specify a column span.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition />
</Grid.ColumnDefinitions>
<!-- Place a layout Grid inside your Grid to deal with controls -->
<Grid Grid.Column="0" Grid.Row="0">
<Grid.RowDefinitions>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<!-- Removed your nested stack panel -->
<StackPanel Grid.Column="0" Grid.Row="0" Orientation="Horizontal">
<Label></Label>
<TextBox></TextBox>
</StackPanel>
<StackPanel Grid.Column="1" Grid.Row="0" Orientation="Horizontal">
<Button />
</StackPanel>
</Grid>
<!-- Add a spilter bar here -->
<!-- No need to span 2 columns anymore... -->
<TelerikGrid:RadGridView Grid.Column="0" Grid.Row="1" >
<TelerikGrid:RadGridView.Columns>
<TelerikGrid:GridViewDataColumn Width="*"/>
</TelerikGrid:RadGridView.Columns>
</TelerikGrid:RadGridView>
<!-- Add a status bar here -->
</Grid>
I have the XAML shown below (for example). If you drag the grid splitter as far as it goes to the left, and keep dragging the mouse, the right-hand column will grow in size outside the bounds of the window - obviously not what I want.
The problem is that I can't set a hard MaxWidth on the right-hand column because the user can resize the window, thus increasing the available space for that column.
So far I think I need to bind the MaxWidth of the right-hand column to something like the window's client area minus the MinWidth of the left plus the width of the splitter column. But I'd like to avoid that if possible. Thoughts?
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Width="450"
Height="300">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" MinWidth="100" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="200" MinWidth="200" />
</Grid.ColumnDefinitions>
<Grid Grid.Column="0">
<Button>Monkey</Button>
</Grid>
<GridSplitter Grid.Column="1" Width="7" ResizeBehavior="PreviousAndNext" />
<Grid Grid.Column="2" Margin="4">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<GroupBox Grid.Row="0" Header="Spaghetti" Margin="0, 0, 0, 5">
<ComboBox HorizontalAlignment="Stretch" VerticalAlignment="Stretch">Noodles</ComboBox>
</GroupBox>
<Expander Grid.Row="1" Header="Batman" IsExpanded="True" Margin="0, 0, 0, 5">
<Button HorizontalAlignment="Stretch" VerticalAlignment="Stretch">Batman!</Button>
</Expander>
</Grid>
</Grid>
</Window>
I'm having the same problem. Maybe this will be a partial answer. I bound the MaxWidth of the column I'm expanding to the ActualWidth of its grid. The goal being that the splitter never exceed the size of its grid. The binding works correctly but it's not achieving the goal because once my grid splitter gets to the edge of the grid, the grid starts resizing larger as I drag the splitter. If we can make the grid not resize with the splitter, this should work.
