如何在WPF应用程序中打开同一窗口中的表单

Question

I am learning c# WPF application.
I have a menu which has a dropdown list. In the dropdown there are 3 other items.
Now on clicking an item i want to display the form in the same window.

What i did is that i have created a new wpf form and navigated it from the previous page.
But now i want to open it in the same page itself.

Please help

XAML:

<Grid>
    <DockPanel Height="43" HorizontalAlignment="Stretch" Name="dockPanel1"
               VerticalAlignment="Top">
        <Menu Height="47" Name="menu1" Width="Auto" DockPanel.Dock="Top"
                VerticalAlignment="Top" HorizontalAlignment="Stretch" >
            <MenuItem Header="_Entry Form" >
                <MenuItem Header="_Student Details" Name="studentDetails" Click="studentDetails_Click_1"/>
                <MenuItem Header="_Faculty Details" Name="facultyDetails" />
                <Separator/>
                <MenuItem Header="E_xit" Name="exit" />
            </MenuItem>
        </Menu>
    </DockPanel>

CS

 private void studentDetails_Click_1(object sender, RoutedEventArgs e)
    {
        // to navigate to a new page
        Student std = new Student();
        this.Close();
        std.Show();


    }

Now i donot want to navigate just display the student page in the same window

Firstly, you'll need to add XAML that represents the Student class, probably a bunch of TextBoxes , wrapped in some kind of container, like a Border , Grid , or StackPanel , and set the Visibility property of the container to Collapsed .

When the button is then clicked, you can populate the text boxes (or other UI elements) with the appropriate Student parameters, then set the container's Visibility property to Visible .

I would really recommend you check out the Model-View-ViewModel (MVVM) pattern, though. There is a bit of a learning curve, but it's well worth the investment.
