1 min read
To update the children collection when any of the TabItem get closed in the Document container, Remove method of DocumentContainer Items collection can be used. The same has been demonstrated in the following code example:
XAML:
<Window x:Class="DocumentContainer_KB.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"> <Grid.RowDefinitions> <RowDefinition Height="40"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <Button x:Name="Button1" Width="100" Height="23" Click="Button1_Click" Content="Remove children" Grid.Row="0"/> <syncfusion:DocumentContainer x:Name="Container" Mode="MDI" Grid.Row="1"> <ContentControl x:Name="Content1" syncfusion:DocumentContainer.Header="Document1"/> <ContentControl x:Name="Content2" syncfusion:DocumentContainer.Header="Document2"/> <ContentControl x:Name="Content3" syncfusion:DocumentContainer.Header="Document3"/> <ContentControl x:Name="Content4" syncfusion:DocumentContainer.Header="Document4"/> </syncfusion:DocumentContainer> </Grid> </Window>
C#
using Syncfusion.Windows.Tools;
namespace DocumentContainer_KB
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Button1_Click(object sender, RoutedEventArgs e)
{
//It is used to remove the item from the collection:
Container.Items.Remove(Content1);
}
}
}
