Keeping WPF grids from getting out of parent bounds
- by Jonathan Perry
In my UI, I have a big grid with two columns and one row. in the right column, I have a grid with three rows where in the top row I have a user control, and in the two bottom rows I have two Expander objects, each containing an ItemsControl with a list that gets populated in runtime. Sometimes, that list gets really long and "spills" from the screen towards the bottom.
What I want to do is to allow the user to see both expanders, be able to expand or collapse them while keeping them both in sight. I tried wrapping them in WrapPanels or StackPanel but to no avail.
Here's some code to help explain my problem:
<Grid Grid.Row="1" x:Name="grid1">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Expander Grid.Row="0" Header="Expander 1" x:Name="expander1" FontSize="14" IsExpanded="True">
<Expander.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FFC4C4C4" Offset="0" />
<GradientStop Color="White" Offset="1" />
</LinearGradientBrush>
</Expander.Background>
<ContentPresenter Content="{Binding ViewModel.OpenAlerts, ElementName=m_viewControl}" ClipToBounds="True"/>
</Expander>
<Expander Grid.Row="1" x:Name="expander2" Header="Expander 2" FontSize="14" IsExpanded="True">
<Expander.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FFC4C4C4" Offset="0" />
<GradientStop Color="White" Offset="1" />
</LinearGradientBrush>
</Expander.Background>
<ContentPresenter Content="{Binding ViewModel.ClosedAlerts, ElementName=m_viewControl}" ClipToBounds="True"/>
</Expander>
</Grid>
Any assistance or tips will be highly appreciated!
Thanks,
John.
