Question

I have a C#.NET web app and would like to save my underlying Model anytime the user navigates off a View. I am using the .Net Entity Framework witha DbContext object. How would I implement a Save on Navigation?

All….thanks for the comments. It was educational. Using the info provided regarding forms and posts, I used buttons to do poast and investigated their valuse to decide what action to perform.

On the Views that had navigation links, I swapped in the input buttons and used CSS to make them look and act like hyperlinks.

and

        <input style="width:40px;" 
            class="navigate_save_header" 
            type="submit" name="NavSave" 
            value="Delete SubTask"
        /> 

The Task Controller has “NavSave” as a parameter into the Edit [POST]….and the value is either “Create SubTask” or “Delete SubTask”. In the controller, I check if “NavSave” is null or not….if not, I then examine the value. If “Create SubTask”, I save the Task Model and navigate to the Subtask Create[GET] method. If “DeleteSubTask”, I save the Task Model and navigate to the Subtask Delete[GET] method. In order to do this, I also have a hidden field containing the SubTask id….so when I Navigate to the Delete[Get] method, I know which SubTask to delete.
