WPF DataGrid Scrollbar
I'm trying to make a WPF开发者_如何学Python DataGrid show scrollbars when necessary. You can see the basic XAML code of my user control below:
<Grid x:Name="Data" Grid.Column="0" VerticalAlignment="Stretch" Height="Auto" HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Expander Header="Route Setup" Grid.Row="0" VerticalAlignment="Top" Background="White">
</Expander>
<Expander Header="Select Locations" Grid.Row="1" VerticalAlignment="Top" Background="White">
</Expander>
<DataGrid Grid.Row="2" ItemsSource="{Binding Locations, Mode=TwoWay}" Height="Auto" AutoGenerateColumns="False" ScrollViewer.CanContentScroll="True"
ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.HorizontalScrollBarVisibility="Auto">
</DataGrid>
This isn't working, I don't see any scroolbars when the DataGrid grows beyond the available space. I've already tried to use a scrollview around my DataGrid but that doesn't change anything.
Update
It might be important to know that the usercontrol is loaded into the LeftRegion
of a shell that has the following markup:
<Grid x:Name="LayoutRoot">
<Grid.ColumnDefinitions >
<ColumnDefinition Width="*" MinWidth="400" MaxWidth="600"/>
<ColumnDefinition Width="9" />
<ColumnDefinition Width="*" MinWidth="300" />
</Grid.ColumnDefinitions>
<GridSplitter x:Name="MainSplitter" HorizontalAlignment="Stretch"
VerticalAlignment="Stretch" Grid.Column="1"
Margin="0" Width="9" Style="{DynamicResource gridSplitterVerticalStyle}"/>
<ItemsControl Name="LeftRegion" Grid.Column="0" Background="Azure" Height="Auto" VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" cal:RegionManager.RegionName="LeftRegion">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Grid/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
<ItemsControl Name="RightRegion" Height="Auto" Background="DarkGreen" VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" Grid.Column="2" cal:RegionManager.RegionName="RightRegion">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Grid/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</Grid>

In your grid named "Data", remove the Height="Auto"
from the third RowDefinition
. At least one row must have the "*" height (which is the default) to take the remaining available space.
Solved it. I needed to remove Height="Auto"
from the thrird RowDefinition
.
