Most effective method for storing and retrieving data on the client side

In my ASP web application, I am facing a challenge with listboxes as changes in item selection happen frequently and quickly. This results in slow performance when trying to retrieve the necessary information through postbacks.

So, I am trying to figure out the optimal way to store data on the client side. Should I consider using postback, ajax, or another approach

The data that needs to be stored can be in a single string format for each item, but I need to account for all items in the Listbox and the number of items is variable.

I would appreciate your insights on the best approach for managing this information effectively.

Answer №1

The level of complexity in your implementation will ultimately dictate the best approach to take. While Postback offers a quick solution, it may lack efficiency and speed. Utilizing AJAX in various ways can significantly enhance performance, with multiple options available for implementation. The decision on how extensively to integrate AJAX will rely on the balance between development time and user benefit/usage frequency.

For a more targeted recommendation, I would advise incorporating AJAX to fetch the data. However, the choice between fetching data each time it's needed or loading it once on initialization will be influenced by the specific application and context.

Answer №2

Just like g.foley mentioned, the solution is highly dependent on the specific context and further details are needed for a proper answer.
In my experience, I once stored a JavaScript object and only sent it upon submitting a form. Perhaps this method might work for you as well.

Answer №3

Based on the context of your question, it seems like you may not necessarily need real-time information from the server every time a selection is made on the listboxes. One approach could be to store the data in JavaScript variables and then send it back to the server through AJAX right before the user navigates to another page or closes the browser. This can help reduce the constant back-and-forth communication with the server. However, it's important to note that Chrome might have issues with asynchronous AJAX calls on unload or beforeUnload, so you may need to make the call synchronous. IE may also have some problems, which could result in a loss of connection to the server, affecting the number of simultaneous connections available.

If my assumption is incorrect and you do require real-time data from the server when selections are made, then your best option would be to utilize AJAX calls to fetch the information promptly (excluding WebSockets).
