Please, let's focus on the horizontal size (width).
I have horizontal StackPanel which auto-resizes to occupy entires space (it "expands"). Within it I have Grid (with 3 columns) and a scrollbar. The scrollbar width should be fixed, but Grid should expand. How can I force it to do it?
Current code:
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
<Grid Name="grid1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
<ColumnDefinition Width="2"></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<StackPanel Orientation="Vertical" Grid.Column="0" HorizontalAlignment="Stretch">
<Label Content="Label" HorizontalAlignment="Center" Name="label1" VerticalAlignment="Bottom" />
</StackPanel>
<GridSplitter DragCompleted="OnDragCompleted" ShowsPreview="True" Name="gridsplitter1" Background="Red" Grid.Column="1" Grid.Row="0" Height="Auto" Width="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
<StackPanel Orientation="Vertical" Grid.Column="2" HorizontalAlignment="Stretch">
<Label Content="Label" HorizontalAlignment="Center" Name="label2" VerticalAlignment="Bottom" />
</StackPanel>
</Grid>
<ScrollBar Name="scrollBarV" Orientation="Vertical" />
</StackPanel>
No matter what I do, width=auto, horizontalalignment=strech, every time each column of the grid occupies only the required space (sufficient for showing its content), not entire space available.
A horizontal StackPanel will always give its children their desired width, so it will never force the Grid to be larger than it wants to be. You will need to use a different kind of panel. One option is to use a DockPanel, and dock the ScrollBar to the right and let the Grid fill in the rest:
<DockPanel HorizontalAlignment="Stretch">
<ScrollBar DockPanel.Dock="Right" Name="scrollBarV" Orientation="Vertical" />
<Grid Name="grid1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
...
</Grid>
</DockPanel>
Another option is to use a Grid with the second column using Auto to size to the ScrollBar exactly and the first column left at the default of 1* to use the rest of the space:
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid Name="grid1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
...
</Grid>
<ScrollBar Grid.Column="1" Name="scrollBarV" Orientation="Vertical" />
</Grid>
Try
<ColumnDefinition Width="*"></ColumnDefinition>
Columns and rows that are defined within a Grid can take advantage of Star sizing to distribute remaining space proportionally. When Star is selected as the height or width of a row or column, that column or row receives a weighted proportion of the remaining available space. This is in contrast to Auto, which distributes space evenly based on the size of the content that is within a column or row. This value is expressed as * or 2* when you use Extensible Application Markup Language (XAML)

I have this built and I add text boxes to it programmatically and update after each addition but the scrollViewer never becomes scrollable just grayed out arrows. I'm only adding textBoxes to one of the stackPanels, could that be it? If so is there some work around for that? I'd appreciate any help, I've spent much too long on this silly problem.
<ScrollViewer x:Name="scrollViewerMain" VerticalScrollBarVisibility ="Visible" HorizontalAlignment="Center" Height="368" Width="410" VerticalAlignment="Top" Margin="150,309,150,-35.5">
<Grid HorizontalAlignment="Left" Height="368" VerticalAlignment="Center" Width="410" ScrollViewer.CanContentScroll="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<StackPanel x:Name="stackPanelPlayerNames" Grid.Column="0" Height="368"/>
<StackPanel x:Name="stackPanelWins" Grid.Column="4" Height="368"/>
<StackPanel x:Name="stackPanelHours" Grid.Column="5" Height="368"/>
<StackPanel x:Name="stackPanelKills" Grid.Column="1" Height="368"/>
<StackPanel x:Name="stackPanelDeaths" Grid.Column="2" Height="368"/>
<StackPanel x:Name="stackPanelRatio" Grid.Column="3" Height="368"/>
</Grid>
</ScrollViewer>
Your Grid should not have a fixed height. If your Grid (inside your ScrollViewer) is ALWAYS 368 pixels tall, and that your ScrollViewer is bigger than 368 pixels tall, then there is always no overflow.
I'm trying to create a MenuItem which contains both a Label and a TextBox. I would like the Textbox's width to stretch to the entire width of the column.
For some reason, the TextBox's width is always small (probably at the length of the text).
Here's my code:
<Grid x:Name="GridLinesRatioGrid" Width="Auto">
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".8*"/>
<ColumnDefinition Width=".2*"/>
</Grid.ColumnDefinitions>
<Label x:Name="GridLinesRatioLabel" Content="Grid Lines Ratio" Foreground="DarkRed" Focusable="False" Grid.Column="0" HorizontalAlignment="Left"/>
<TextBox x:Name="GridLinesRatioTextBox" Foreground="DarkRed" Height="20" HorizontalAlignment="Stretch" Grid.Column="1"/>
</Grid>
What am I missing here?
I have image and 3 textblock. I want place image left and 3 TextBlock in rows right. I've tried this:
<Grid x:Name="Grid">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Image Grid.RowSpan="3"
Source="image.jpg" Stretch="Uniform" HorizontalAlignment="Left" VerticalAlignment="Top"/>
<TextBlock Grid.Column="1"
Text="11"
FontSize="25"/>
<TextBlock Grid.Column="1"
Grid.Row="1"
Text="22"/>
<TextBlock Grid.Column="1"
Grid.Row="2"
Text="33" FontSize="14"/>
</Grid>
But I have large space between rows when image is big. How I can do this?
If you want the image to remain its size... simply get rid of the grid rows and throw the TextBlocks into a vertical StackPanel.
If you want to resize your image so that it has the same height as the 3 TextBlocks... you can bind the Height of the Image to the ActualHeight of whatever container you put the TextBlocks in, like this:
<Grid x:Name="Grid">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Image Height="{Binding ActualHeight, ElementName=myStackPanel}" Source="image.jpg" Stretch="Uniform" HorizontalAlignment="Left" VerticalAlignment="Top"/>
<StackPanel Grid.Column="1">
<StackPanel Name="myStackPanel">
<TextBlock Text="11" FontSize="25"/>
<TextBlock Text="22"/>
<TextBlock Text="33" FontSize="14"/>
</StackPanel>
</StackPanel>
</Grid>
I would try to make a grid with 1 row and 2 columns.
In the first column i would place the image.
In the second column i would place a stack panel with vertical flow.
Then add the textblocks to the stackpanel.
I have an explorer type window that I am trying to display in WPF.
<Grid ScrollViewer.VerticalScrollBarVisibility="Disabled">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="350" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<telerik:RadTreeView Grid.Column="0" Name="ExplorerTree"
ScrollViewer.VerticalScrollBarVisibility="Visible"/>
<GridSplitter Grid.Column="1" Grid.Row="1" Width="1" Grid.RowSpan="1" HorizontalAlignment="Center" VerticalAlignment="Stretch"/>
<telerik:RadListBox Grid.Column="2" Grid.Row="1" ScrollViewer.VerticalScrollBarVisibility="Visible" />
</Grid>
However, when I expand an object within the tree view, the scroll bar appears on the grid causing the entire window to scroll rather than just the contents of the tree view. What do I need to change to make the contents of the tree view scroll instead? I don't want to set it to a specific height as I would like the height of the tree view to adjust with the height of the parent in which it is displayed.
If you just stop trying to set ScrollViewer properties altogether you should get the desired result as both RadTreeView and RadListBox will display a ScrollViewer automatically as needed (unless you have something else in the rest of your XAML that interferes with their normal behavior). I used both these controls extensively without setting any ScrollViewer properties in XAML and that's what they do automatically although you might have to set their VerticalAlignment to stretch... not sure about that.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="350" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<telerik:RadTreeView Grid.Column="0" Name="ExplorerTree"
VerticalAlignment="Stretch"/>
<GridSplitter Grid.Column="1" Grid.Row="1" Width="1" Grid.RowSpan="1"
HorizontalAlignment="Center" VerticalAlignment="Stretch"/>
<telerik:RadListBox Grid.Column="2" Grid.Row="1" VerticalAlignment="Stretch" />
</Grid>
Here is my Siverlight Grid script, I want Media Element mediaPlayer to occupy left half of the whole Grid space, and want Media Element cameraPlayer to occupy right half of the whole Grid space. But my following code does not work quite well (I have set related Grid column/row value), two Media Elements play overlap.
Any ideas what is wrong?
<Grid x:Name="LayoutRoot2" Margin="0" Background="#FF0D0A0A" Cursor="Hand" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<MediaElement HorizontalAlignment="Stretch" Margin="10,10,10,10" x:Name="mediaPlayer" AutoPlay="false" Grid.Column="0" Grid.Row="0"/>
<MediaElement HorizontalAlignment="Stretch" x:Name="cameraPlayer" AutoPlay="false" Grid.Column="1" Grid.Row="0"/>
</Grid>
thanks in advance,
George
You need to define your column definitions on your grid.
<Grid x:Name="LayoutRoot2" Margin="0" Background="#FF0D0A0A" Cursor="Hand" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition
Width="specify width" />
<ColumnDefinition
Width="specify width" />
</Grid.ColumnDefinitions>
<MediaElement HorizontalAlignment="Stretch" Margin="10,10,10,10" x:Name="mediaPlayer" AutoPlay="false" Grid.Column="0" Grid.Row="0"/>
<MediaElement HorizontalAlignment="Stretch" x:Name="cameraPlayer" AutoPlay="false" Grid.Column="1" Grid.Row="0"/>
</Grid>
you'll need to specify the width that you want your column to be.
