Hello,

I would like to catch the grid request i.e. when sorting or grouping via server and execute on some modal dialog when OK clicked. As I understand on requestStart we can perform some actions, but further execution flow will proceed. In my case I would like to display login dialog + some other login selections and if login succeeds, continue with the request. Is it possible?

Thanks

Hello,

You could prevent the request initially by using the event argument preventDefault method and then when OK is clicked and the login succeeds, manually trigger the request with the dataSource read method. You will also need to use a flag or dynamically bind and unbind the requestStart handler so that the request is not prevented when calling read. I created an example that demonstrates the basic logic.
