2009.Q3 still some efforts needed improving usage of RadGrid Export

[CSurieux]

Hello,

RadGrid is a good tool ...but could be improved.

I discovered the finally integrated buttons to export to Excel, Word,pdf,csv...perfect.
But I am still disapointed we still have to add manually javascript to the page:

<script type="text/javascript">
            function onRequestStart(sender, args)
            {
                if (args.get_eventTarget().indexOf("ExportToExcelButton") >= 0 ||
                    args.get_eventTarget().indexOf("ExportToWordButton") >= 0 ||
                    args.get_eventTarget().indexOf("ExportToPdfButton") >= 0 ||
                    args.get_eventTarget().indexOf("ExportToCsvButton") >= 0)
                {

                    args.set_enableAjax(false);
                }
            }
        </script>

This should be done by control !

And we should have a way to add from codebehind several javascript functions which would be called OnRequestStart.


Thanks Telerik for this tool but thanks doing some more efforts.

Hello Christian,

Thank you for sharing your opinion.

Although such option would be useful, it is a bit tricky to be implemented. As far as I know, there is no feasible approach that would have been suitable for both Telerik and ASP.NET controls.

At this point, I can only suggest you simplify your code a bit:

<script type="text/javascript">
   function onRequestStart(sender, args)
   {
      if (args.get_eventTarget().indexOf("ExportTo") != -1)
         args.set_enableAjax(false);
   }
</script>

Thank you Daniel ,

Even if your answer is a kind of dummy RTFM.
You know I have in my code dozen of small pieces of javascript to maintain.
And I prefer maintaining C# than javascript for many good reasons.

If I only consider the Ajax OnrequestStart, it is already used:
1) to center a loading panel,
2) to avoid Radgrid Export buttons doing callback
3) To avoid some Radprogress to fire when a callback is unnecessary....
etc.

My pages are loaded dynamically via user controls under a limited number of pages/masterpages containers, so it is uneasy to change the OnRequestStart for each special module need, and I must include all possibilities in an ever growing OnRequestStart.
Having a kind of general container for javascript to trigger on Ajax request start, and allowing to fill it dynamically on each request would be better.
Are you sure that nothing could be done to improve this.

Best regards.

Hello Christian,

I believe I understand your position well. There are various ways you could reuse the code, thus avoiding unnecessary repetitions. The attached demo implements one of the possible approaches - there is only a single line in the main file (Default2.aspx) - all javascript reside in external file, thus ensuring the code is easy to maintain.
I hope this helps.
