How can I make the maximize-button invisible in a ProWindow?

[DirkTillmanns]

I set the intended property ShowMaxRestoreButton to false (regardless of whether in XAML or constructor). As you can see in the screenshot, ProWindow seems to manipulate this property during the initialization of the dialog. My WindowsStyle is ToolWindow. Maximize shouldn't be displayed even without being explicitly set. Everything works correctly in System.Windows.Window. ProWindow inherits from this.

Does somebody has any idea?

Forgot, I work with ArcGIS Pro 3.3.0

Hi,

Adding ResizeMode="NoResize" to ProWindow xaml will hide maximize and minimize buttons and disable windows resizing.

<controls:ProWindow x:Class="************"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:controls="clr-namespace:ArcGIS.Desktop.Framework.Controls;assembly=ArcGIS.Desktop.Framework"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        ResizeMode="NoResize"

Hi,

That's not a solution. I want to allow a resize. But a maximize doesn't make sense in my dialog.

I think there are bugs in the Pro SDK here. Pro manipulates "System.Windows.Window", which it derives from, certainly unintentionally. For example, a "ToolWindow" has no maximize button by default in "Window". But in "ProWindow" it does.

I just ran into this problem myself today.  Here's a workaround that worked for me:  As others mentioned, you'll still need to disable resizing in the XAML, but in this version it'll just be temporary.  You'll also need to set the window's Loaded event to execute a method named Window_Loaded.

ResizeMode="NoResize"
ShowMaxRestoreButton="False"
Loaded="Window_Loaded"

Next, go to your code-behind, and implement this method:

private void Window_Loaded(object sender, RoutedEventArgs e) =>
    this.ResizeMode = ResizeMode.CanResize;

So the window will get initialized without the Max button being visible, then Window_Loaded will execute, and re-enable resizing later.  The button should not reappear afterward.
