Executes the callback method after all processing is completed and before updating the client.
The Post() method is similar to the BeginInvoke() method used by desktop applications. It allows you to execute a block of code out of sync with the current execution flow.
Prints the specified window.
The window is printed without the caption or the borders, if present.
Prints the entire browser window.
Causes the application to reload on the browser.
Removes the filter from the list of registered event filters.
Requests the browser to enable fullscreen mode if supported.
Executes the callback in context.
Instructs the client to start polling the server for UI changes at the specified interval when a WebSocket connection is not available.
Calling this method when is true has no effect. Use client side polling when you know that your code will start a background task that needs to update the client asynchronously (push updates) and your server or clients don't support WebSocket connections. Once the background tasks are completed call to reduce the incoming requests from the client.
Throws:
The interval specified is less than 1.
Starts a new task within the current application context and returns immediately. See also .
Returns: . An awaitable .
The task runs in the background but it's still capable of updating the client asynchronously when working with WebSocket by calling the method to push the UI updates to the client browser. If you want to support background updates for clients or servers that can't use the WebSocket connection, you can either add a component to the parent container to force period requests to the server, or you can use the and methods.
Starts a new task with a return value within the current application context and returns immediately. See also .
Returns: .
The task runs in the background but it's still capable of updating the client asynchronously when working with WebSocket by calling the method to push the UI updates to the client browser. The generics overload of allows the task to return a value. You can use this with the async/await pattern and asynchronously wait for the task to complete. If you want to support background updates for clients or servers that can't use the WebSocket connection, you can either add a component to the parent container to force period requests to the server, or you can use the and methods.
Note that you don't have to specify the type in the angular brackets, the compiler will automatically detect the type from the return value of the asynchronous function.
Starts a bound to the current session context.
Returns: . An instance of .
You must save a reference to the returned or the Garbage Collector will stop and dispose the timer. To alter the invocation period user Timer.Changer(), or stop the timer simply use Timer.Dispose(). See .
Executes the optional callback in context and pushes all the pending updates to the client when in WebSocket mode.
Use this method when you need to update the client asynchronously from an out-of-bound thread (different thread, not originating from a client request). You can call this method at the end of the code that updates the UI:
Or you can use the optional action function to enclose the code that updates the UI in a block and ensure that the client is updated when the code block exits:
Fired when the active window changes.
Fired when the application is about to shut down.
Fired when the application is reloaded in the browser because the user hit refresh or changed the URL.
Fired when the application is started, after the Main method is called.
Fired when the browser fires the "beforeinstallprompt" event. Corresponds to .
Fired at the beginning of every request.
Fired when the user resizes the browser.
Fired when the user activates the browser tab.
Fired when the user deactivates the browser tab.
Fired when the changes.
Fired at the end of every request.
Fired when the focused control changes.
Fired when the hash part of the URL changes on the client side.
Fired when the current thread has completed processing all the events and before the response is sent back to the client.
Fired when the active responsive profile is changed.
Fired when the value changes.
Fired when the session is about to time out.
The default behavior built-in Wisej is to display a dialog asking the user to prolong the session. Set Handled to true to stop the default behavior.
Fired when the current theme is changed.
Fired when a thread exception is thrown.
Read the applications's system information. Use StartupPath, ProductName, ProductVersion, etc.
Listen to the application's global events. See SessionTimeout , BeginRequest, ApplicationStart, ApplicationExitApplicationRefresh, BrowserSizeChangedResponsiveProfileChanged, CultureChanged, and many more.
Manage all live components in the session. Through the Application class you can find, iterate, inspect all live components of any type. See OpenForms for all the currently created (visible or invisible) instances of Form. OpenPages returns all the created Page objects. FindComponent and FindComponents provide an easy way to find any component in the session or to iterate the list of components that match a custom expression.
Start background tasks in context. StartTask provides a powerful way to start a background task on the server that can keep interacting with the client browser while running independently.
Manage the application's theme. Use LoadTheme to load a Wisej theme into the application. Or use the Theme object to read all sorts of information from the current ClientTheme.
Terminate the application without waiting for the session to timeout. Use Exit to terminate the current session and free all the related memory.
