I'm more interested in doing it in the XAML. I only tried that because I wanted to illustrate what I had tried.

Just to make sure - your resources start with the <ResourceDictionary> tag right?

Hi All,

I am developing a WYSIWYG editor using Silverlight 4.0 RichText box. I am able to insert images in the RichText box editor, but not able to add shapes (Line, Eclipse, Rectangle etc.)

Can anyone provide me a pointer to do so?

Thanks.

What have you tried so far?

Did you try
myrichTextBox.Selection.Insert(container);
where container is an layout control (say, a stackpanel) containing a shape.

Thanks Abhinav for your reply. I tried inserting a shape using UIControl.

My requirement is to add shapes like rectangle, ellipse with the same functionality (resize, backcolor, shadow etc) as provided by Word or Visio.

I will try the option suggested by you and will let you know.

Thanks.

Resizing GridSplitter

Hi,

I am a beginner in WPF and following Sams WPF in 24 hrs. There is an exercise to do a FontViewer application using grid which displays the list of system fonts and let the user choose any font and view the corresponding font applied on a sample text. I tried using a GRIDSPLITTER which is not resizing at all. Here is the code.

<Window x:Class="FontViewerGrid.Window1"

        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="190.667*" />
            <ColumnDefinition Width="387.333*" />
        </Grid.ColumnDefinitions>

Also, it looks like you had two splitters. I took one out. If you want a splitter for rows too, give that splitter it's own row. This shows just the column splitter:

      <ColumnDefinition Width="387.333*" />
  </Grid.ColumnDefinitions>

Creating a resize effect

WebMaster14-May-10 7:26

14-May-10 7:26

Hello,

I want to have a Grid with zero "width" (alas you can't see it) being resized as an effect when I click enter in my program. (Kind of like this: http://www.bestbefore.ro[^] --> click on one of the links and see how the "lines" resize)
However, I have no clue as how to do it. No sample code whatsoever. I would like it to be done via code, or atleast be able to start the effect through code.

Here is my project and source code: http://www.sendspace.com/file/k2vus0[^]
I realize it's a kind of lame project name, but it's a school task. (And I'm not used to WPF, so the "I'm the expert" doesn't really apply :P)

Thanks,
Theo

What you want is a storyboard, which basically allows you to animate by transitioning a property from one value to another. For example, you can make a storyboard that transitions from the color red to the color blue, gradually. There is also the DoubleAnimation you can use in a storyboard, which allows you to transition from, say, the value 0 to the value 1.5, gradually. You'd want to use this DoubleAnimation storyboard to modify a width.

If you want to do more complex grid animations (e.g., by resizing specific columns), you're gonna want to read this article. In fact, you might want to start by reading that article. It gives a good introduction to storyboards and animations.

Hello,

Thanks for the links. However now I am stuck. This code doesn't do anything - my lines just keeps not being visible.

double left = horizontalLineContainer.Margin.Left;
double top = horizontalLineContainer.Margin.Top;
double right = horizontalLineContainer.Margin.Right;
double bottom = horizontalLineContainer.Margin.Bottom;
horizontalLineContainer.Margin = new Thickness(left, top, left, bottom);
ThicknessAnimation animation = new ThicknessAnimation();
animation.Duration = new TimeSpan(0, 0, 2);
animation.From = horizontalLineContainer.Margin;
animation.To = new Thickness(left, top, right, bottom);
Storyboard.SetTarget(animation, horizontalLineContainer);
Storyboard.SetTargetProperty(animation, new PropertyPath(Grid.MarginProperty));
Storyboard storyboard = new Storyboard();
storyboard.Children.Add(animation);
storyboard.Begin();

Thanks,
Theo

OK, so I got it to display. It seems it does the animation, but it's extremely fast, no matter what TimeSpan I enter, be it 2 or 20000 seconds. Here's my code:

double left = horizontalLineContainer.Margin.Left;
double top = horizontalLineContainer.Margin.Top;
double right = horizontalLineContainer.Margin.Right;
double bottom = horizontalLineContainer.Margin.Bottom;
horizontalLineContainer.Margin = new Thickness(left, top, left, bottom);
horizontalLineContainer.Visibility = Visibility.Visible;
ThicknessAnimation animation = new ThicknessAnimation();
animation.Duration = new TimeSpan(0, 0, 20000);
animation.From = horizontalLineContainer.Margin;
animation.To = new Thickness(left, top, right, bottom);
Storyboard.SetTargetName(animation, horizontalLineContainer.Name);
Storyboard.SetTargetProperty(animation, new PropertyPath(Grid.MarginProperty));
Storyboard storyboard = new Storyboard();
storyboard.Children.Add(animation);
storyboard.Begin(horizontalLineContainer);

NOTE: I would like to say that this is very urgent, as this is a school task due monday. Any help is appreciated.

Thanks,
Theo

I don't see how that works at all. The "From" and "To" are identical.
