hei,
assume that i have this code:
<StackPanel>
<Canvas x:Name="canvas" Height="400" Width="235">
<Image x:Name="image" Source="/SplashScreenImage.jpg" Stretch="Fill">
<Image.RenderTransform>
<CompositeTransform ScaleX="0.5" ScaleY="0.5"/>
</Image.RenderTransform>
</Image>
<TextBlock Canvas.ZIndex="1" Text="TextBlock" Canvas.Left="61" Canvas.Top="150"/>
</Canvas>
<TextBlock HorizontalAlignment="Center" >Test</TextBlock>
</StackPanel>
What i want to do is the canvas's width and height properties linked to image. something like this:
<Canvas x:Name="canvas" Height="{image Height}" Width="{image Width"}>
since I have been previously using Qt Quick and this is quite easy, they call it property binding. I am wondering if this is possible in XAML as well ?
Thanks.
I think I found the solution, example:
<StackPanel>
<TextBox Margin="10" x:Name="txtData" />
<TextBlock Margin="10"
Text="{Binding ElementName=txtData,
Path=Text}" />
</StackPanel>

I need to place images side by side and need to place one small image icon below the each image.please help me how to design ?any samples please let me know..
How to place userimage inside one small image dynamically based on condition..please help me..
I made simple prototype for you. I can't make whole screen for you. Here are the basic things as I got from your comments and screenshot. Please see XAML and screenshot below:
<ListBox Name="lstImages" VerticalAlignment="Top">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="Padding" Value="0,0,0,-15" />
<Setter Property="Margin" Value="2"/>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel>
</toolkit:WrapPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<Image Height="100" Width="110" Source="{Binding BigImageSource}" VerticalAlignment="Top"/>
<Image Height="10" Width="10" Source="{Binding SmallImageSource}" VerticalAlignment="Top" HorizontalAlignment="Right" Margin="0,-35,10,0"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Use this
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Image Source="Your image" Grid.Row="0"/>
<Image Source="Your small icon" Grid.Row="1"/>
</Grid>
<Grid Grid.Column="1">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Image Source="Your image" Grid.Row="0"/>
<Image Source="Your small icon" Grid.Row="1"/>
</Grid>
</Grid>
<StackPanel>
<StackPanel Orientation="Horizontal">
<Image Source="Firstimage" />
<Image Source="Secondimage" />
</Stackpanel>
<StackPanel Orientation="Horizontal">
<Image Source="Firsticon" />
<Image Source="Secondicon" />
</Stackpanel>
</StackPanel>
But here you have to make some changes to the icon stackpanel like setting some margin, inorder to make it aligned to the actual images.
This is just an alternative, you can also use Grid's as answered by nucleons
If you want to show your images in listbox then wrap this way in wrap panel and you can set direction of wrappanel as well. Wrappanel is found in silverlight toolkit of windows phone 7.
<ListBox Name="lstImages">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="Padding" Value="-15" />
<Setter Property="Margin" Value="0"/>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel>
</toolkit:WrapPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<stackpanel>
<Image Source="Your image" />
<Image Source="Small image" />
</stackpanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
and bind this listbox with your collection of data.
I have created a page where there's alot of input from the user. So the User should be able to scroll down to be able to press a Upload button. To scroll down on the page I have used a ScrollViewer outside a grid. I am able to scroll but the page keeps scrolling back after scrolling down.
Here is my code:
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanelButtom" Grid.Row="1" >
<ScrollViewer >
<Grid x:Name="ContentPanel" Background="black">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="154" />
<ColumnDefinition Width="326" />
</Grid.ColumnDefinitions>
<Image Height="109" HorizontalAlignment="Left" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="167" Margin="23,19,0,0" Source="{Binding Path=ImageSoruce, Mode=TwoWay}" Grid.ColumnSpan="2" />
<TextBox Height="71" HorizontalAlignment="Left" Margin="12,161,0,0" Name="nameInput" Text="{Binding Path=Name, Mode=TwoWay}" VerticalAlignment="Top" Width="430" Grid.ColumnSpan="2" />
<TextBlock Height="56" HorizontalAlignment="Left" Margin="23,134,0,0" Name="nameLabel" Text="Name" VerticalAlignment="Top" Width="130" FontSize="25" />
<TextBlock FontSize="25" Height="60" HorizontalAlignment="Left" Margin="23,238,0,0" Name="descriptionLabel" Text="Description" VerticalAlignment="Top" Width="130" />
<TextBox Height="72" HorizontalAlignment="Left" Margin="12,265,0,0" Name="descriptionInput" Text="{Binding Path=Description, Mode=TwoWay}" VerticalAlignment="Top" Width="430" IsEnabled="True" Grid.ColumnSpan="2" />
<TextBlock FontSize="25" Height="60" HorizontalAlignment="Left" Margin="23,343,0,0" Name="locationLabel" Text="Location" VerticalAlignment="Top" Width="130" />
<TextBlock Height="46" HorizontalAlignment="Left" Margin="24,384,0,0" Name="locationInput" Text="{Binding Path=Location, Mode=TwoWay}" VerticalAlignment="Top" Width="401" Loaded="locationInput_Loaded" Grid.ColumnSpan="2" />
<toolkit:ListPicker SelectionMode="Multiple" FullModeHeader="CATEFORIES" x:Name="ListPickerCategories" CacheMode="BitmapCache" HorizontalAlignment="Left" Margin="25,492,0,0" VerticalAlignment="Top" Width="401" Grid.ColumnSpan="2" ItemsSource="{Binding Categories}" Height="78"></toolkit:ListPicker>
<TextBlock FontSize="25" Height="60" HorizontalAlignment="Left" Margin="24,436,0,0" Name="textBlock1" Text="Categories" VerticalAlignment="Top" Width="130" />
<Button Content="Upload" Height="86" HorizontalAlignment="Left" Margin="26,604,0,0" Name="UploadButton" VerticalAlignment="Top" Width="411" Click="UploadButton_Click" Grid.ColumnSpan="2" />
</Grid>
</ScrollViewer>
</Grid>
What can be the cause of this problem and how do I solve it?
Use StackPanels to put elements one below the other. Remove all your margins, height, width and other absolute positioning stuff
<Grid x:Name="ContentPanelButtom" Grid.Row="1" >
<ScrollViewer>
<StackPanel>
<!-- elements here -->
</StackPanel>
</ScrollViewer>
</Grid>
I had the same issue. but at last i solved it, i just used the Height property to do this. Please do the following steps
First create a ScrollViewer
Indide the ScrollViewer create a container(eg: Grid/StackPanel/Border etc...) and put every controlls inside it.
Set fixed Height for ScrollViewer and the Container (Note: Height of container should be greater than ScrollViewer's Height)
See the below Code
<ScrollViewer Height="500">
<Grid Name="Container" Height="700">
<TextBox/>
<TextBox/>
<TextBox/>
</Grid>
</ScrollViewer>
Now you can scroll the container Grid Even the KeyBoard shown or even focus on a TextBox.
<ListBox Margin="0,2,0,0" SelectionChanged="OnSelectionChanged" ScrollViewer.VerticalScrollBarVisibility="Disabled" x:Name="lstUcpPanel" ItemContainerStyle="{StaticResource myContainerStyle}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<toolkit:WrapPanel Width="Auto" Height="Auto" Margin="-7,-8,-7,0" ItemWidth="246" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderThickness="1" Margin="3.5,1,0,0" BorderBrush="Transparent">
<StackPanel Orientation="Vertical" Background="LightGray">
<Image Height="115" Width="115" Margin="2" Source="{Binding categoryImageName}" ></Image>
<TextBlock Text="{Binding name}" TextWrapping="Wrap" Foreground="Black" HorizontalAlignment="Center"></TextBlock>
</StackPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I am using the above code for showing a data as in following format:
but when the [name] is long like "Settings flkjadsflka fdsaflksdj flhasdjhfl asd", then the design becomes like this:
What i want to know is that is there anyway i can show the items in a uniform format without any distortion with uniform height of the item.
Set the stretch property on your image to Stretch="Fill"
<Image Height="115" Width="115" Margin="2" Source="{Binding categoryImageName}" Stretch="Fill" ></Image>
How about giving the items in the WrapPanel a fixed Height?
<toolkit:WrapPanel ItemHeight="80" ... />
Another day another problem, this time I think with a simple issue into XAML formatting.
I have a ListPicker in a StackPanel on a XAML page in a WP7 app. Whenever I tap the ListPicker, it expands, but it appears to expand behind the item below it. If I have enough items in the list it opens in full screen mode which works fine.
Any suggestions, pointers would be appreciated;

I have been through the examples on the windowsphonegeek.com site, but I still can't make it work!
The issue is that you're setting the Height of the ListPicker to 100. Remove that, and just leave as auto. This is an issue b/c when you restrict the height, the listpicker has nowhere to expand (thus, showing the behavior you're seeing)
I guess height is creating an issue, just make sure that height of listpicker is greater than stackpanel.
I'm trying to scroll a large textblock horizontally. I tried couple of the following way. None of the works for me. Can anyone tell me how to do it?
Try 1:-
<Canvas x:Name="myCanvas" Height="590" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Width="700">
<ScrollViewer x:Name="sv" Canvas.Left="1" Canvas.Top="520" HorizontalScrollBarVisibility="Auto">
<TextBlock Canvas.Left="2" Canvas.Top="522" Height="62" Name="textBlock1" Text="TextBlockTextBlockTextBlockTextBlockTextBlockTextBlock111111222222" Width="590" />
</ScrollViewer>
</Canvas>
Try 2:-
<Canvas x:Name="myCanvas" Height="590" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Width="700">
<StackPanel Orientation="Horizontal" Canvas.Left="1" Canvas.Top="520" Height="100" Name="stackPanel1" Width="635">
<ScrollViewer x:Name="sv" Margin="1,1,1,1" HorizontalScrollBarVisibility="Auto">
<TextBlock Canvas.Left="2" Canvas.Top="522" Height="62" Name="textBlock1" Text="TextBlockTextBlockTextBlockTextBlockTextBlockTextBlock111111222222" Width="590" />
</ScrollViewer>
</StackPanel>
Try 3:-
<Grid Canvas.Left="1" Canvas.Top="500" Height="200" Name="grid1" Width="640">
<StackPanel Orientation="Horizontal" Canvas.Left="1" Canvas.Top="500" Height="100" Name="stackPanel1" Width="635">
<ScrollViewer x:Name="sv" Margin="1,1,1,1" HorizontalScrollBarVisibility="Auto">
<TextBlock Canvas.Left="2" Canvas.Top="500" Height="62" Name="textBlock1" Text="TextBlockTextBlockTextBlockTextBlockTextBlockTextBlock111111222222" Width="590" />
</ScrollViewer>
</StackPanel>
</Grid>
<Grid x:Name="LayoutRoot" Background="Transparent">
<ScrollViewer HorizontalScrollBarVisibility="Visible">
<TextBlock Width="1000" Height="500" TextWrapping="Wrap" Text="asasdgasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdf" />
</ScrollViewer>
</Grid>
If I understood correctly this should solve your problem.
