ListView Expands Height But Doesn't Contract It - WPF Discussion Boards

Re: Styling an AdornerLayer

5-Sep-09 2:39

Hi
I want to know if it is possible to make an AdonerLayer look exactly like a BalloonTip, if yes, has anyone done this before and would you be so kind as to post the style that you created? It's not that important for me to get this working, so I don't want to spend too much time on styling elements.

Thanks in advance

You can find more styling information on balloon tips in this article[^] from my fellow WPF Disciple Philipp Sumi.

3D model as Splash

ListView Expands Height But Doesn't Contract It

5-Sep-09 2:27

Hi
I have a 3D model that I want to use as my SplashScreen. I can easily put the model on a form, then make the form transparent so that you see only the 3d model, but what I want to do is display this form as my SplashScreen. Do you think using a transparent form with a 3D model is the way to go or is there another, possibly better way of achieving this? If not, could you give me some hints on how to use a WPF window as a SplashScreen?

I'd just use the SplashScreen that was introduced in 3.5 SP1. Here's[^] more information.

It seems that the WPF ListView expands when the content height increases, but it does not contract when the content height decreases. Here is a simple example that demonstrates the issue:

XML

<Window x:Class="TestShrinkListView.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300">
    <Border BorderThickness="2" BorderBrush="Red" VerticalAlignment="Top">
        <ListView Height="Auto" VerticalAlignment="Top">
            <ListViewItem>
                <TextBox AcceptsReturn="True">Type some text here.</TextBox>
            </ListViewItem>
        </ListView>
    </Border>
</Window>

If you run that and press ENTER a few times, you'll make the TextBox increase it's height, and the ListView will expand to accommodate the new height. However, if you delete a few lines from the TextBox, the ListView remains at the same enlarged height.

Is there an easy way to make the ListView decrease its height when the content shrinks (e.g., a height property), or am I going to have to get clever with some special coding?

If I have to get clever, one thing I did notice is that removing a ListViewItem from the ListView causes the ListView to contract to the proper size. I suppose I could look into how that exactly happens, but I would really prefer a cleaner solution.

If you have any ideas, please run them by me. I'd love to hear your opinion. Thanks!

I have today off, but after a full night's sleep, my mind is less clouded than it was yesterday when I ran out of programmer-fu. The problem we ran into yesterday is now bugging me to find a resolution.

We have a web service on an internal IIS server that is not on the company domain. This server has a number of WCF web services running on it so we can test our client application.

The endpoint defined in the application's app.config uses the server's IP address in the URL. However, when we try to connect via the application to the web service, the IP is changed (internally) to the machines name.

Does anybody know why it does it that?

Yeah, that's one of the many "difficulties" we face. We're writing the application from hell:

- WPF
- WCF
- nHibernate
- RDB

As you can see, the further you get down the list, the more likely it is that you will exclaim, "WTF!?".

So, let me guess. At the end of the list, there should be InstallShield - that you're using to create setup?

No, the install shield part has been outsourced to another country; communication with them is done using Lotus Notes.
And on the top of it, John forgot to mention the legacy VB6 library used in a part of his code that has also to be maintained.

That's the problem with big frameworks. You get them to work but most of the times you don't fully understand why and how they are working. This produces, in the best scenario, a slow application, in the worst an application with many subtle reliability defects.

Using a resource in multiple places

Hi
I have a rather simple question. If I declare a ModelVisual3D as a resource in XAML, how can I use this resource in multiple places without getting the error " Specified Visual is already a child of another Visual or the root of a CompositionTarget" ?

In your resource file, use the Shared attribute so your resource gets cloned each time you use it.

For example:

<ModelVisual3D x:Shared="False" ...>
   ...
</ModelVisual3D>

Etienne_1234-Sep-09 1:01

I can't access this attribute at all?? I tried "Shared, x:Shared, isShared" and none of them exist. Do I have to reference something specific first?

This only works if your item is defined in a ResourceDictionary.
