WebImagePanViewer Client Object
The LEADTOOLS WebImagePanViewer control includes a client-side Javascript class to update the server control without posting the entire page back to the server. Most of the WebImagePanViewer server properties can be accessed through the Javascript class. You can access the LEADTOOLS WebImagePanViewer control on the client-side by using the ASP.NET generated ClientID on the WebForm.
Client Naming
The client-side version of the control uses the same naming convention as the server control version for easier coding. All LEADTOOLS public class definitions in the WebImageViewer.js and Utilities.js files contain the prefix "ltwf" to avoid conflicts with any other components on the page.
Client Public Methods/Properties
All server side object properties can be accessed on the client by using two methods: "GetServerPropertyName", and "SetServerPropertyName", where "ServerPropertyName" is replaced with the name of the property to be accessed or set.
The following table lists the Server properties and the mapped client methods:
