New to Telerik UI for ASP.NET AJAXStart a free 30-day trial

Examples

It is possible to increase the flexibility of the RadWindowManager and RadWindow by configuring them dynamically in the code-behind, based on external conditions on the page. The code below shows:

  • Looping through the Windows collection of a RadWindowManager

  • Setting properties to RadWindowManager and RadWindow objects

  • Creating a new RadWindow dynamically and adding it to the RadWindowManager Windows collection or as a separate control in the form (for ASP.NET AJAX feature only)

  • Retrieving a window from the RadWindowManager Windows collection and configuring it.

C#
private void Page_Load(object sender, System.EventArgs e)
{
	//Set properties present only in RadWindowManager
	//Set skin
	WindowManager.Skin = "Monochrome";
	//Set the same height to all windows
	WindowManager.Height = Unit.Pixel(250);
	int offsetLeft = 0;
	//Loop through all windows in the WindowManager.Windows collection
	foreach (Telerik.Web.UI.RadWindow win in WindowManager.Windows)
	{
		//Set whether the first window will be visible on page load
		win.VisibleOnPageLoad = true;
		//Set the behavior (whether the window will allow to be minimized, maximized and/or pinned)
		win.Behaviors = Telerik.Web.UI.WindowBehaviors.Maximize | Telerik.Web.UI.WindowBehaviors.Close;

		//Set OffsetElementId - the id (ClientID if a runat=server is used) of a html element, which, when clicked, will automatically open/show the Telerik RadWindow
		win.OffsetElementID = "OffsetElement";
		//Top and Left can be used in conjunction with the OffsetElementId (if no OffsetElementId is specified, the top left corner of the browser window is used
		win.Top = 15;
		win.Left = offsetLeft;
		offsetLeft += 100;
	}

	//Create a new window add it dynamically
	//The window will inherit the default settings of parent WindowManager
	Telerik.Web.UI.RadWindow newWindow = new Telerik.Web.UI.RadWindow();
	newWindow.NavigateUrl = "http://www.sitefinity.com";
	//Set OpenerElementId - the id (ClientID if a runat=server is used) of a html element, which, when clicked, will automatically open/show the Telerik RadWindow
	newWindow.OpenerElementID = OpenerButton.ClientID;
	//Set OffsetElementID - the id (ClientID if a runat=server is used) of a html element, whose left and top position will be used as 0,0 of the Telerik RadWindow object when it is first shown
	newWindow.OffsetElementID = OpenerButton.ClientID;
	//Top and Left can be used in conjunction with the OffsetElementId (if no OffsetElementId is specified, the top left corner of the browser window is used
	newWindow.Top = Unit.Pixel(22);
	newWindow.Left = Unit.Pixel(0);
	//OPTION 1
	//Add the newly created RadWindow to the RadWindowManager's collection
	//WindowManager.Windows.Add(newWindow);
	//OPTION 2
	//since in the for ASP.NET AJAX version you can have a RadWindow outside of a RadWindowManager
	//as a separate control, you can add the newly created RadWindow directly to the form's Controls collection
	form1.Controls.Add(newWindow);

	//Get a reference to the first window in the list
	Telerik.Web.UI.RadWindow firstWindow = WindowManager.Windows[0];
	//Set its navigate URl to be different
	firstWindow.NavigateUrl = "https://www.telerik.com/products/sharepoint/overview.aspx";
