confirm page change on kendo grid

[Logan]

I am allowing my users to select rows in a kendo grid via a checkbox in the first column and right now the selections are lost if/when they change pages.  I was hoping there would be a way i could show a confirm dialog when when they click the page, but before the page changes and either
1) allow them to perform an action on the selected rows
2) lose the selections
3) stop the page change from occurring

I am having trouble actually stopping the page change from happening.  Are there any samples on how to do this?

Thanks,
-Logan

Hello Logan,


You could use the requestStart event of the dataSource to detect the page change.
E.g.

.DataSource(dataSource => dataSource
   .Ajax()
   .Events(e => e.RequestStart("requestStart"))

var prevPage = 1;

function requestStart(e) {
    if (this.page() !== prevPage) {
        //paging is performed
        if (<custom condition to prevent the paging>) {
            e.preventDefault();
        } else {
            //perform paging and store the current page number
            prevPage = this.page();
        }
    }
}

I hope this information helps. Have a great day!
