HotSpotCollection.RemoveAt Method
Assembly: System.Web (in system.web.dll)
The following code example demonstrates how to programmatically add two CircleHotSpot objects to an ImageMap control. After the two CircleHotSpot objects are added to the HotSpotCollection collection, the RemoveAt method is used to delete the object located at the first index in the collection. For this example to work correctly, you must supply your own image for the ImageUrl property and update the path to the image appropriately so that the application can locate it.
<%@ page language="C#" %> <script runat="server"> void Page_Load (Object sender, EventArgs e) { // Programmatically create a CircleHotSpot object. CircleHotSpot Circle1 = new CircleHotSpot(); Circle1.HotSpotMode = HotSpotMode.Navigate; Circle1.NavigateUrl = "http://www.tailspintoys.com"; Circle1.X = 145; Circle1.Y = 120; Circle1.Radius = 75; Circle1.AlternateText = "Shop for toys"; // Programmatically create a second CircleHotSpot object. CircleHotSpot Circle2 = new CircleHotSpot(); Circle2.HotSpotMode = HotSpotMode.Navigate; Circle2.NavigateUrl = "http://www.cohowinery.com"; Circle2.X = 145; Circle2.Y = 290; Circle2.Radius = 75; Circle2.AlternateText = "Shop for wine"; // Add the HotSpot objects to the ImageMap's // HotSpotCollection. Shop.HotSpots.Add(Circle1); Shop.HotSpots.Add(Circle2); // Use the RemoveAt method to delete the HotSpot // object at the first index in HotSpotCollection. Shop.HotSpots.RemoveAt(0); } </script> <html> <head id="Head1" runat="server"> <title>HotSpotCollection.RemoveAt Example</title> </head> <body> <form id="Form1" runat="server"> <h3>HotSpotCollection.RemoveAt Example</h3> <h4>Shopping Choices:</h4> <asp:imagemap id="Shop" imageurl="Images/ShopChoice.jpg" alternatetext="Shopping choices" runat="Server"> </asp:imagemap> </form> </body> </html>
