ImageClickEventArgs Class

This class passes the location where a user clicked an HtmlInputImage server control or an ImageButton Web server control. Clicking an HtmlInputImage server control causes a ServerClick event to occur, while clicking an ImageButton server control causes a Click event to occur. You can then use event handlers to programmatically respond to the event based on the value of these coordinates.

Note
The origin coordinates (0,0) are located at the upper left corner of the image.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The following code example demonstrates an ASP.NET page that uses the information provided by this class to display the coordinates of a user's click on an image.

// Define the event handler that uses coordinate information through ImageClickEventArgs.
void ImageButton_Click(object sender, ImageClickEventArgs e) 
{
   Label1.Text = "You clicked the ImageButton control at the coordinates: (" + 
                 e.X.ToString() + ", " + e.Y.ToString() + ")";
}
