Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Represents the method that handles any events that are raised when a user clicks an image-based ASP.NET server control.
public delegate void ImageClickEventHandler(System::Object ^ sender, ImageClickEventArgs ^ e);
public delegate void ImageClickEventHandler(object sender, ImageClickEventArgs e);
type ImageClickEventHandler = delegate of obj * ImageClickEventArgs -> unit
Public Delegate Sub ImageClickEventHandler(sender As Object, e As ImageClickEventArgs)
Parameters
- sender
- Object
The server control that is the source of the event.
An ImageClickEventArgs that contains event data.
Examples
// 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() + ")";
}
' Define the event handler that uses coordinate information through ImageClickEventArgs.
Sub ImageButton_Click(sender As Object, e As ImageClickEventArgs)
Label1.Text = "You clicked the ImageButton control at the coordinates: (" & _
e.X.ToString() & ", " & e.Y.ToString() & ")"
End Sub
Remarks
This delegate defines the required signature for all click events raised when a user clicks an image-based ASP.NET server control. You must use the signature defined by this delegate for any OnServerClick
event handlers that you create for an HtmlInputImage server control or any OnClick
event handlers that you create for an ImageButton Web server control.
If you create a custom image-based ASP.NET server control that users can click, use this delegate to define the events associated with that user action.
