Working with RadWindow

This topic will explain you how to work with the RadWindow in details.

Create a RadWindow

In order to use the RadWindow in your application you have to add a reference to the Telerik.Windows.Controls.Navigation assembly in your project.

After the reference is available, you can declare a RadWindow. Here is an example.

RadWindow radWindow = new RadWindow(); 
radWindow.Width = 400; 
radWindow.Height = 300; 
Dim radWindow As New RadWindow() 
radWindow.Width = 400 
radWindow.Height = 300 

Show the RadWindow

When you want to display the RadWindow you have two options - to display it as a window or as a modal dialog window.

To learn more about modal windows read here.

Call the Show() method of the RadWindow instance to open it as a normal window.


Call the ShowDialog() method of the RadWindow instance to open it as a modal dialog window.

Add content to the RadWindow

To add a content to the RadWindow you can use either the Content or the ContentTemplate properties.

If you have a window-specific content, use the Content property.

As the Content property is of type object you can set it to any control you like. If you want to have a more complex content that consists of more than one control, be sure to wrap them inside a layout control and pass the layout control as content.You can also set the content of the RadWindow to a UserControl.

The only scenario, where you can add content to the RadWindow at design-time, is when the RadWindow represents an entire user control. To learn more about that read here.

Grid grid = new Grid(); 
grid.Background = new SolidColorBrush(Color.FromArgb(255, 240, 255, 255)); 
radWindow.Content = grid; 
Dim grid As New Grid() 
grid.Background = New SolidColorBrush(Color.FromArgb(255, 240, 255, 255)) 
radWindow.Content = grid 

If you want to share a common layout structure for the content of multiple windows, define an appropriate DataTemplate and set it to the ContentTemplate property of the RadWindow.

    <DataTemplate x:Key="WindowContentTemplate"> 
        <Grid Background="Azure" /> 

radWindow.ContentTemplate = this.Resources["WindowContentTemplate"] as DataTemplate; 
radWindow.ContentTemplate = TryCast(Me.Resources("WindowContentTemplate"), DataTemplate)

Program the RadWindow

The RadWindow exposes a few methods, that allow you to programmatically control its behavior. Here is a list of them:

  • BringToFront: Attempts to bring the RadWindow over any other RadWindows except topmost.

  • Close: Closes the RadWindow.

Modify the appearance of the RadWindow

To modify the default appearance of the RadWindow you can use the following properties:

  • BorderBrush: Changes the outer border of the RadWindow and the outer border of its content area.

  • Background: Changes the background of the content area.

  • CaptionHeight: Gets or sets the height of the extent of the top of the window threatened as the caption.

  • CornerRadius: Gets or sets a value that represents the degree to which the corners of the window are rounded.

Also you can create a style and apply it to the RadWindow or modify the default template of the RadWindow to change its overall look. To learn more read the Styles and Templates section.
