[Solved] Persisting current page and selection on Grid?

[David]

I'd like a grid to have the same page and row selected when they come back to the page that they had when they left. I figured I could keep the page and row ID in a cookie and restore them when the grid loads again, but there's a few problems.

For one, I can't find a method to get the current page, only set the page. Also there's no distinct event for changing a page, just row data binding.

Also I don't see a client side method on the grid to set the selected row.

Is what I'm trying to do possible?

Hi David,

You can use the pageTo() JavaScript method to set the current page on the client-side.

We currently do not support setting the current page from the server side. The good news is that we recently implemented this feature and you will be able to set the current page from the paging configuration. Let me know if you need this functionality and I will send you our latest internal build.

Indeed there is no client-side method to select a row. You can use jQuery to add the required CSS class:

$('#Grid').find('tbody tr:eq(1)').addClass('t-state-selected')

I hope this helps,

I found the pageTo() method. I was actually looking for a way to get the current page and react to the user switching pages. (In order to save the current page and bring it back later)

I will look into the jQuery statement.

Hi David,

 The current page can be retrieved from the currentPage field:

var currentPage = grid.currentPage;

Thanks. Didn't find that in the documentation. Is there an event that lets you know when a user has switched pages? I would also need this event in order to persist the current page.

(By the way, sorry for not posting this in the Grid forum)

Hi David,

 The OnDataBinding event is raised whenever the grid needs to bind - paging, sorting, filtering etc.
