Passing dataset or datatable between two pages u

Question

I've a popup to enter the data and once the data is added, I need to show data in parent page Gridview. But that data don't need to be stored until I click the save button below the Gridview in the parent page. It will still be displayed and maintained on the screen - (like it has active/inactive button).

When I click the save below the gridview, it will be stored in the database all at once. I need to do this using javascript. How can I do that?

I'm working on asp.net web project.

Answer 1

You can save your data temporarily using localStorage instead of your database for instance:

localStorage.setItem('myDataName', 'myDataValue') // Save data

And:

localStorage.getItem('myDataName') // Get data

This works for strings. If you want to save objects or arrays of objects, you must convert them to strings like this:

localStorage.setItem('myDataName', JSON.stringify(myObject)) // Save object

Answer 2

Take a look at LocalStorage

The localStorage property allows you to access a local Storage object. localStorage is similar to sessionStorage. The only difference is that, while data stored in localStorage has no expiration time, data stored in sessionStorage gets cleared when the browsing session ends—that is, when the browser is closed.

It should be noted that data stored in either localStorage or sessionStorage is specific to the protocol of the page.

Store Data

localStorage.setItem('Key', 'YOUR_DATA');

Read Data

var YOUR_DATA = localStorage.getItem('Key');

You can also store objects by stringifying it.

localStorage.setItem('Key', JSON.stringify(YOUR_DATA_OBJ));

when reading parse to object

var YOUR_DATA_OBJ = JSON.parse(localStorage.getItem('Key'));
