How to restrict the resizing of the float window width in WPF DockingManager?

1 min read

In WPF DockingManager, you can restrict the resizing of the width of the float window by using the CanResizeWidthInFloatState property. This is a boolean property that restricts the resizing of the width of float window for the corresponding floating child depending upon the values. When the CanResizeWidthInFloatState property is set as True, the width of the float window can be resized and when the CanResizeWidthInFloatState Property is False, the width of the float window unable to resize. Refer to the following code examples.

XAML

//This code shows how the CanResizeWidthInFloatState property is set as true for the corresponding floating child in the DockingManager
<Window x:Class="DockingManager_floatwindowsample.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:syncfusion="http://schemas.syncfusion.com/wpf"
        Title="MainWindow" Height="350" Width="525">
    <Grid x:Name="Grid1">
       <syncfusion:DockingManager x:Name="Dock1"  UseDocumentContainer="True"  >
         <ContentControl syncfusion:DockingManager.Header="Dock1"
                         syncfusion:DockingManager.CanResizeWidthInFloatState="True"
                         syncfusion:DockingManager.State="Float">               
         </ContentControl>
         <ContentControl syncfusion:DockingManager.Header="Dock2"
                          syncfusion:DockingManager.State="Dock">
         </ContentControl>
         <ContentControl syncfusion:DockingManager.Header="Dock3"
                          syncfusion:DockingManager.State="Dock">
         </ContentControl>
         <ContentControl syncfusion:DockingManager.Header="Dock4"
                          syncfusion:DockingManager.State="Document">
       </ContentControl>
         <ContentControl syncfusion:DockingManager.Header="Dock5"
                          syncfusion:DockingManager.State="Document"
         </ContentControl>
       </syncfusion:DockingManager>
    </Grid>
</Window>

//This code shows how the CanResizeWidthInFloatState property is set as true for the corresponding floating child in the DockingManager
using Syncfusion.Windows.Tools.Controls;
namespace DockingManager_floatwindowsample
{
     /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            DockingManager Docking = new DockingManager();
            Docking.UseDocumentContainer = true;
            ContentControl content1 = new ContentControl();
            DockingManager.SetHeader(content1, "Dock1");
            DockingManager.SetState(content1, DockState.Float);
            DockingManager.SetCanResizeWidthInFloatState(content1, true);
            ContentControl content2 = new ContentControl();
            DockingManager.SetHeader(content2, "Dock2");
            DockingManager.SetState(content2, DockState.Dock);
            ContentControl content3 = new ContentControl();
            DockingManager.SetHeader(content3, "Dock3");
            DockingManager.SetState(content3, DockState.Dock);
            ContentControl content4 = new ContentControl();
            DockingManager.SetHeader(content4, "Dock4");
            DockingManager.SetState(content4, DockState.Document);     
            Docking.Children.Add(content1);
            Docking.Children.Add(content2);
            Docking.Children.Add(content3);
            Docking.Children.Add(content4);
            Grid1.Children.Add(Docking);
            }}

Output:

The following output displays how the width of the float window is resized to some extent:
