<avalonDock:DockingManager>
    <avalonDock:LayoutRoot>
        <avalonDock:LayoutPanel>
            <avalonDock:LayoutDocumentPane>
                <avalonDock:LayoutDocument Title="个人信息">
                    <avalonDock:LayoutDocument.Content>
                        <Grid>
                            <TextBlock Text="{Binding Name}" />
                        </Grid>
                    </avalonDock:LayoutDocument.Content>
                </avalonDock:LayoutDocument>
            </avalonDock:LayoutDocumentPane>
        </avalonDock:LayoutPanel>
    </avalonDock:LayoutRoot>
</avalonDock:DockingManager>

public class Person
{
    public string Name { get; set; }
}

// 在代码中设置数据上下文
Person person = new Person();
person.Name = "John Doe";
dockLayout.DataContext = person;
