HtmlInputImage.ServerClick Event

Occurs on the server when the user clicks an HtmlInputImage control.

Namespace: System.Web.UI.HtmlControls
Assembly: System.Web (in system.web.dll)

public event ImageClickEventHandler ServerClick
/** @event */
public void add_ServerClick (ImageClickEventHandler value)

/** @event */
public void remove_ServerClick (ImageClickEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The ServerClick event is raised when the user clicks an HtmlInputImage control.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to specify and code a handler for the ServerClick event to determine the coordinates where the user clicks the HtmlInputImage control.

<%@ Page Language="C#" AutoEventWireup="True" %>

<script runat="server">
      
  protected void  ImageBtn_Click(object sender, ImageClickEventArgs e)
  {

    // Write the click coordinates to the Span1 element.
    Span1.InnerText = "You clicked at (" + e.X.ToString() +
                      ", " + e.Y.ToString() + ").";
  }
  
</script>

<html> 
<body>

   <form runat="server">

      <h3>Click the Image </h3>

      <input type="image"
             alt="Image Alternate Text"
             src="Image1.jpg" 
             OnServerClick="ImageBtn_Click"
             runat="server" id="Image1"/>

      <br />
      <br />

      <span id="Span1" 
            runat="server"/>

   </form>

</body>
</html>
   

<%@ Page Language="C#" AutoEventWireup="True" %>

<script runat="server">
      
  void ImageBtn_Click(Object sender, ImageClickEventArgs e)
  {

    // Display the coordinates of the position where the image 
    // was clicked. 
    Span1.InnerText = "You clicked at (" + e.X.ToString() +
					  ", " + e.Y.ToString() + ").";

  }

  void Page_Load(Object sender, EventArgs e)
  {

    // Create an EventHandler delegate for the method you want to 
    // handle the event, and then add it to the list of methods called
    // when the event is raised.
    Image1.ServerClick += new ImageClickEventHandler(this.ImageBtn_Click);

  }

</script>
