The MVC version of TX Text Control provides a JavaScript API to load and save documents locally:
- Javascript: TXTextControl.loadDocument method
╰ TX Text Control .NET Server for ASP.NET
╰ JavaScript API
╰ TXTextControl Object
╰ loadDocument Method
Loads text in a certain format. - Javascript: TXTextControl.saveDocument method ╰ TX Text Control .NET Server for ASP.NET
╰ JavaScript API
╰ TXTextControl Object
╰ saveDocument Method
Saves the current document in a certain format and sends the result back asynchronously by calling a given callback function.
These client-side methods are very useful when managing your data including documents client-side. In case you would like to store your documents server-side, you would need to save it locally in order to send it to the server again. For a saving process, the document is being sent twice using HTTP.
Because the document is already server-side (it gets synchronized with the document synchronization service), you can use a little trick to save the document directly server-side without the overhead of sending it back and forth.
The following code stores Text Control settings including the ConnectionID that can be used server-side to connect to the proper instance:
The following function calls a Web API endpoint with the given ConnectionID:
In the controller code, the ConnectionID is used to retrieve the associated instance of the WebSocketHandler:
Then the LoadText method can be used to load the document directly server-side which updates the view in the HTML5 canvas automatically.
The following diagram shows the workflow for this scenario:
