Adjusting Panels in WPF programatically ?

Hi,

I am working on WPF controls, I have a halt at adjusting one of the controls programatically.
I have 2 radiobuttons (rdbtn1, rdbtn2) and a dockpanel(2 controls) with a stackpanel(with textbox and button)a another stackpanel(with 2 textboxes).

so the panels are placed at (40,10,0,0) and (40,150,0,0) with panel1 above and panel2 below it.

actually the problem is selecting one of radiobuttons .
if i select rdbtn2, the panel1 shuld be invisible and the panel2 should stretch (not shift, which mean if the panel2 height is 200 and it should stretch its starting point in vertical to 10 and its lower limit should be same , making total height of 140 + 200 )to the panel1 starting location .

so, only panel2 shuld be visible. how to do this programatically in C#?

Please help..

Thank you,
Ramm

I would put them in a stackpanel or a grid, and try to set them up so their size is determined by the available space, so that when you collapse one, the other would fill the space.

Global Styles - Update

Okay, I found out what's eating my (non-keyed) global style. I had this in my app.xaml (my global textbox style is in Styles.xaml):

<ResourceDictionary Source="/PresentationFramework.Aero;V3.0.0.0;31bf3856ad364e35;component/themes/aero.normalcolor.xaml" >
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/WpfTest;component/Dictionaries/Resources.xaml" />
        <ResourceDictionary Source="/WpfTest;component/Dictionaries/Styles.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

When I changed it to this, all of a sudden my style started to work as expected:

<ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/WpfTest;component/Dictionaries/Resources.xaml" />
        <ResourceDictionary Source="/WpfTest;component/Dictionaries/Styles.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

0) Why does this work like this? Is it a bug or "as designed"?

1) The reason I was adding the aero.normalcolor resource dictionary was to force XP to use the aero theme. How do I force the aero look and still be able to use my own global style overrides? Can I do this and get the same results?

<ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/PresentationFramework.Aero;V3.0.0.0;31bf3856ad364e35;component/themes/aero.normalcolor.xaml" />
        <ResourceDictionary Source="/WpfTest;component/Dictionaries/Resources.xaml" />
        <ResourceDictionary Source="/WpfTest;component/Dictionaries/Styles.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

How to display a document in silverlight?

Sadly, I found out that SL 3 doesn't support the FlowDocument.
I need to load a xaml file from the server into the client browser. No problem doing that using the webservice. The problem is how to display the file in a page and allow for printing.

NOTE: The xaml file is actually a simple table having 2 columns and several rows with simple text attributes

Use Themes?

We have a number of button images used in our app. As expected, management isn't sure that it's happy with the current images, so I am trying to come up with several different sets that can easily be swapped into the application. What's the best way to go about doing this? Is "use themes" the answer? If so, can someone steer me to relevant discussions/examples?

I'm not sure how theming work, never did it myself.
Although this codeplex library can help perhaps?
http://wpfthemes.codeplex.com/[^]

In my case I use object template in the App resource if I want to change the look of the object.

But your case is a it different.
You don't specially want to change the look of button in general (or so it seems) but of individual button in particular...

Maybe their image content or whatever could be:
<Button Content="{StaticResource buttonFooContent}">

And then in you app resource you can define
<SomeUI x:Key="buttonFooContent" x:Shared="true" />

and you can change the content anytime in the App resource file and everyone will get it!
How about that?! Smile | :)

Use XAML file as vector image

Jack Valmadre30-Jul-09 12:01

Jack Valmadre

30-Jul-09 12:01

Hi,

I have a few vector images in XAML format that I'd like to display in my application. So far I've been able to do this using:

private XmlReader reader_;
private UIElement control_;
...
reader_ = XmlReader.Create(filename_);
control_ = (UIElement)XamlReader.Load(reader_);

Then having a Control property:

public UIElement Control
{
    get
    {
        return control_;
    }
}

And binding to this as below:

<DataTemplate DataType="{x:Type local:Tile}">
  ...
    <Viewbox>
      <Label Content="{Binding Control}" />
    </Viewbox>
  ...

This works, but when I try and display the control in multiple controls in the same window, only one will appear. I was able to fix it by doing this:

public UIElement Control
{
    get
    {
        XmlReader reader = XmlReader.Create(filename_);
        return (UIElement)XamlReader.Load(reader);
    }
}

But I'd really like to avoid parsing the XAML and reloading the control every time I use it! This is my first WPF project. Can someone recommend a better way of doing this?

Cheers!

Jack

How to define windows property in resourcedictionary

vidster30-Jul-09 3:23

Re: How to define windows property in resourcedictionary

30-Jul-09 3:23

I'm just looking into using WPF and have a simple problem.

I just want to style a treeview control, but when I add the styling to my resource dictionary, I get error :

"The attached property 'Window.Resources' is not defined on 'ResourceDictionary' or one of its base classes."

The xml is :

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<Window.Resources>

<Style TargetType="{x:Type TreeViewItem}">

..........

</Style>

</Window.Resources>

</ResourceDictionary>

Window.Resources is needed to define a resource in your Window XAML (in the same way as UserControl.Resources is used in a UserControl, and so on). You don't need this in a resource dictionary, so you need to remove the lines

:<Window.Resources>

and

</Window.Resources>

I want to keep styling seperate. I have defined the resourcedictionary in the Application XAML, so it should work?

That's right. Just remember that it's an application resource, so you don't have to wrap it in a container Resources section such as a Window.Resources.

Re: How to define windows property in resourcedictionary

30-Jul-09 23:21

Yes, but I'm not setting the style in the Application XAML, I just want to point it to my resource dictionary (Styles.XAML) :

<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>

Pete O'Hanlon31-Jul-09 1:08

31-Jul-09 1:08

I think you misunderstand me. Because you have created this in a ResourceDictionary, you don't need the Window.Resources part - that's what I mean by application resources. The way you are merging your resource dictionary in is spot on.
