I am going through the process of designing my first Silverlight application based upon the PivotViewer control from Silverlight 4. I am having problems organizing the bar at the top as per my design:
(source: richard-slater.co.uk)I have found ways of left aligning the Logo and Title, a way of right aligning the buttons with various combinations of panels however there are two major problems with it.
- The XAML looks really really ugly, nesting panels seems to work but doesn't seem like good practice.
- I can't seem to find a way of handling resizing the window down without either clipping or overlapping.
I have acheived the best results with the following code:
<StackPanel x:Name="LayoutHeader" Margin="4" Height="50" Grid.Column="0" Grid.Row="0" Orientation="Horizontal">
<Image x:Name="LogoImage" Height="50" W开发者_JAVA技巧idth="50" Source="/EVEMonPivot;component/EVEMonLogoBlue.png" Grid.Column="0" Grid.Row="0" />
<TextBlock x:Name="TitleText" Height="50" Text="EVEMon Pivot" FontSize="40" Grid.Column="1" Grid.Row="0" VerticalAlignment="Center" FontWeight="Bold" Padding="10,0,0,0" />
</StackPanel>
<StackPanel x:Name="NavHeader" Margin="4" Height="50" Grid.Column="0" Grid.Row="0" Orientation="Horizontal" HorizontalAlignment="Right">
<Button x:Name="StackExButton" Style="{StaticResource NavButton}" Click="StackExButton_Click">EVE Online StackExchange</Button>
<Button x:Name="BugsButton" Style="{StaticResource NavButton}">Bugs & Suggestions</Button>
</StackPanel>
I intend to move some of the properties into styles, however it still feels messy.
The above code can also result in the following in small windows:
(source: richard-slater.co.uk)Is there a better way?
If you don't like nesting panels, a Grid might be a better option. With your four elements, have a five column grid like this:
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Image x:Name="LogoImage"
Height="50"
Width="50"
Source="/EVEMonPivot;component/EVEMonLogoBlue.png"
Grid.Column="0" />
<TextBlock x:Name="TitleText"
Height="50"
Text="EVEMon Pivot"
FontSize="40"
Grid.Column="1"
Grid.Row="0"
VerticalAlignment="Center"
FontWeight="Bold"
Padding="10,0,0,0" />
<Button x:Name="StackExButton"
Grid.Column="4"
Style="{StaticResource NavButton}"
Click="StackExButton_Click">EVE Online StackExchange</Button>
<Button x:Name="BugsButton"
Grid.Column="5"
Style="{StaticResource NavButton}">Bugs & Suggestions</Button>
</Grid>
This sets four columns to Auto-size, so they adjust to the size of your UI elements, and the centre column is Star-sized so it fills the rest of the space between them.
While you can use a star-sized grid column to enforce a collapsible region between the controls, you're still left to account for what happens when there simply isn't enough room (eg. 600 pixels of display in a 400-pixel wide area.) What I think you need is a ScrollViewer, which is a ContentControl that lets you determine when scroll bars appear.
In the markup below I am doing 2 things: First, I am using the Silverlight toolkit's DockPanel to isolate the left and right sections of the display (a very similar thing can be accomplished with a 3-column Grid with Cols 0 and 2 set to "Auto" and Col 1 set to "*", but the specific use of Left and Right in the DockPanel may make the intent more readable.) Second, the whole thing is being wrapped in a ScrollViewer with the HorizontalScrollBarVisibility set to "Auto" - when the contents is too big to fit, put up a scrollbar.
