grid events

[ramaMember]

We have a grid where we support inline editing for some of the columns. we dont sent the updates as they change but we track all of them and with a click of a button we send all the changes. because of this we want to give a warning dialog if there are unsaved changes and the user tries to sort or page away from the current page. overriding the sort on source we show a warning if there are unsaved changes. but if i put the logiv in pager method on source, it is not getting called whne i select the next page. How do i get the event of changing the page so that i can warn the user if there are unsaved changes,

Hi,

For triggering page changes, use the “pagechanged” event.

$("#jqxGrid").on("pagechanged", function (event) 
{
    var args = event.args;
    var pagenum = args.pagenum;
    var pagesize = args.pagesize;
});

This doesnt help. I receive the event but the page changes to the next page. What I need is a way to be notified before the event happens.
This is what I need>

1) The user can make several changes to values on the grid. I have a button which when clicked saves all the changes at once on the server.
2) If the user tries to navigate to the next page with out saving his changes, I want to show a warning window. If they say discard changes, I want to go the page they want to navigate to. If they say no, don’t go to the next page.
3) I was able to do it with sorting by implementing source.sort function.

Hi,

“pagechanged” is raised when a page is changed. That is the expected behavior. If you want to implement a different logic, then you should override the default paging as demonstrated in our “pager renderer” sample.
