Silverlight virgin here. How do I make the usercontrol surrounding my grid automatically resize to accomodate the grid width inside? Currently the usercontrol is displaying at about 300 or 400 pixels when the browser window is much wider. It renders both vertical and horizontal scroll bars around the data grid which is ugly. I want to set the control width to "100%", but this does not appear to be supported. What am I missing?
Here's my xaml so far:
<UserControl x:Class="RichMedia.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data">
<Grid x:Name="LayoutRoot" Background="White">
<data:DataGrid Name="dataGrid1" AutoGenerateColumns="False"
HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
DataContext="{Binding}" />
</Grid>
</UserControl>
EDIT: I should add that I am using the default containers in Visual Studio 2010 created when adding a silverlight app to an existing Web Application Project.
