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";
