  • Reference

Definition

Namespace:
System.Web.UI.WebControls
Assembly:
System.Web.dll

Inserts a specified HotSpot object into the HotSpotCollection collection at the specified index location.

public:
 void Insert(int index, System::Web::UI::WebControls::HotSpot ^ spot);
public void Insert (int index, System.Web.UI.WebControls.HotSpot spot);
member this.Insert : int * System.Web.UI.WebControls.HotSpot -> unit
Public Sub Insert (index As Integer, spot As HotSpot)

Parameters

index
Int32

The array index at which to add the HotSpot object.

spot
HotSpot

The HotSpot object to add to the collection.

Examples

The following code example demonstrates how to programmatically add two CircleHotSpot objects to an ImageMap control. The HotSpots property is used to access the HotSpotCollection collection. The Add method adds Circle2 to the collection. The Insert method adds Circle1 to the collection at the first element, in front of Circle2. 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.
