Hi,

This width should depend upon the parent elements width or it should depend upon the ViewModel property that is binding to this textblock.

According to any of them it should able to take the value and wrap the text and fit within the browser but should not stretch beyond the browser size or monitor size.

Thanks,
Abdul

Then a Canvas isn't necessarily the proper parent element - it rarely is except for drawings and shapes etc. There's better panel elements for layout if you don't need pixel-level positioning.

If you must use a canvas then you could handle the canvas' SizeChanged event and in your handler code resize and/or reposition the textblock based on the values of the canvas' ActualWidth/ActualHeight properties.

Hi I have a class library with code that is compatible with both Silverlight and standard .net libraries. (the minor incompatibilities can be solved with #if)
How I can compile the code for both of these platforms? I mean - how do I set up Visual Studio to have two output configurations - one for .net, one for silverlight, so that my bin folder will contain two compiled .dlls?
The project was initially created as Widnows Class Library and now I don't even know how to tell the VS to use Silverlight libraries to begin with Frown | :-(

To answer my own question, the following links have some useful info (different approaches):
http://www.wintellect.com/CS/blogs/krome/archive/2011/05/24/sharing-code-between-silverlight-and-wpf-using-build-targets.aspx[^]
http://msdn.microsoft.com/en-us/magazine/ee321573.aspx[^]
The latter brought to my attention the possibility of file linking between projects, which I completelly forgot is possible.

Let user adjust control size

I want to create a control and use its size as data input from user. So adjust the control size by user's mouse is required, just like what we do to the window? Is there any existing property we can set to do this in WPF Confused | :confused:

Here[^] is an excellent article on how to move and reshape controls in your app.

Good Luck!

WPF Hyperlink Question

Kevin Marois24-Oct-11 9:51

24-Oct-11 9:51

I have styled a list so that the list items appear as hyperlinks. Here's my xaml:

<UserControl.Resources>

    <converters:ProjectTypeImageValueConverter x:Key="projectTypeConverter"/>

    <!--This is the template for the Recent projects list items-->
    <DataTemplate DataType="{x:Type local:RecentProjectModel}">
        <StackPanel Orientation="Horizontal"
                    Margin="2">
            <Image Source="{Binding ProjectType, Converter={StaticResource projectTypeConverter}}"
                    Margin="0,0,5,0"/>
            <TextBlock Width="150">
                <Hyperlink Foreground="RoyalBlue">
                    <TextBlock Text="{Binding Caption}"/>
                </Hyperlink>
            </TextBlock>
        </StackPanel>
    </DataTemplate>
        
</UserControl.Resources>

and

<ListBox x:Name="lstRecent"
            Grid.Row="1"
            Grid.Column="0"
            ItemsSource="{Binding RecentProjects}"
            SelectedItem="{Binding SelectedRecentProject}"
            BorderThickness="0"
            Margin="3"
            MinWidth="235"/>

When I click the link, the SelectedRecentProject is not set. If I click the image of the list item, it is set. How do I set the SelectedRecentProject when the link is clicked?

Thanks

Wow, I had to write a quick sample app for this one. The Hyperlink / TextBlock combo is eating the mouse down. You'll notice that the selection changed event never gets fired. You can set IsHitTestVisible="False" on the TextBlock (but you will lose the hand cursor)... or you need to derive a "HyperlinkEx" class from Hyperlink and set the focus to the parent yourself, or you can change controls to something else Smile | :)

. If you are OK with losing the hand cursor when they mouse over the link, the the IsHitTestVisible="False" is the quickest fix.

EDIT: actually, you probably need to do the derived class thing on TextBlock since Hyperlink isn't a UI element. Just derive a class from TextBlock and override PreviewMouseLeftButtonDown and chase up the visual tree til you hit the ListBoxItem. I whipped this out in a few seconds and it works without losing the hand cursor. I'll leave the clean up / error checking to you Smile | :)

.

public class TextBlockEx : TextBlock
{
public TextBlockEx()

: base()
{
this.PreviewMouseLeftButtonDown += new MouseButtonEventHandler(HyperlinkEx_PreviewMouseLeftButtonDown);
//this.MouseLeftButtonDown += new MouseButtonEventHandler(HyperlinkEx_MouseLeftButtonDown);
}

void HyperlinkEx_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
object v = this;

while (v != null)
{
if (v is ListBoxItem)
{
((ListBoxItem)v).IsSelected = true;
((ListBoxItem)v).Focus();
break;
}
v = VisualTreeHelper.GetParent((DependencyObject)v);
}

e.Handled = true;
}
}

ya, that did it. I'll deal with the cursor some other time. It's not that big of a deal right now.

I edited the message as you responded... I've got the "TextBlockEx" working for you... just needs a bit of clean up Smile | :)

and doesn't lose the mouse cursor Smile | :)

I have this data template

HTML

<UserControl.Resources>
        
    <!--This is the template for the Recent projects list items-->
    <DataTemplate DataType="{x:Type local:RecentProjectModel}">
        <StackPanel Orientation="Horizontal">
            <Image Source="/...;component/Media/Graphics/abtech_triangle_blue_small.png"
                    Margin="0,0,5,0"/>
            <TextBlock Width="150">
                <Hyperlink>
                    <TextBlock Text="{Binding Caption}"/>
                </Hyperlink>
            </TextBlock>
        </StackPanel>
    </DataTemplate>
        
</UserControl.Resources>

I would like to change the image based off the value of a property called ProjectType on the RecentProjectModel class.

How do I do this?

Thanks

Just bind to ProjectType and use a value converter, or have your VM expose an ImageSource property and bind to that directly. Is your binding to Caption working? I seem to recall there are some issues when using binding inside of a data template, but I can't recall off the top of my head.

Kevin Marois24-Oct-11 8:30

24-Oct-11 8:30

Yes the caption is working.

Never used a converter before. Got an exmaple?

This has a simple example on both the C# side and the XAML side:

http://msdn.microsoft.com/en-us/library/system.windows.data.ivalueconverter.aspx[^]

Its just a method that WPF will pass in a ProjectType to and you will decide based on that what ImageSource you want to return... actually, I think just returning the URL string will work too.
