Scheduler resurces availability

[Oleg]

Hi All.
Could you please help me to find the best way to check availability of GroupBy resources for Scheduler. I have Employee resource (LinqDataSource) and need to cancel GroupBy parameter for scheduler if there is no emploees in the list. All I tried get an error cant change GroupBy during binding process. (or something like this)

Thanks.

Hi Oleg,

You may try to set the GroupBy property in the Load event instead aspx file like in the code bellow:

private void Page_Load(object sender, EventArgs e)
        {
            if ("some rule")
            {
                RadScheduler1.GroupBy = "Room";
            }
        }

Hope this will help.

Hi Oleg,
I was tackling this one just yesterday.
In addition to what Plamen has suggested, I also had to set the GroupBy on the view settings.
I think this is because I am setting DayView-GroupBy declaratively on the scheduler tag.

* Edit - checking the appointment count does not work for me because it returns the appointment count of the scheduler from the requesting page, and not the appointment count from the resulting page!

So if it doesn't work for you right away, you might need to follow suit and put something like this in your PageLoad:

protected void Page_Load(object sender, EventArgs e)
    {
        // Supress grouping in day view if no appointments present
        if (rsScheduler.Appointments.Count == 0)
        {
            rsScheduler.DayView.GroupBy = "";
        }
        else
        {
            rsScheduler.DayView.GroupBy = "Venue";
        }
    }

Hi All.
Thanks for your answers but this didn't bring me closer to solve my issue. Cause I cant catch the event when I can check number of rows in my Employee resource data sorce (LinqDataSource) and set GroupBy according to result.
I tried :

protected void LinqDataSource3_OnSelected(object sender, LinqDataSourceStatusEventArgs  e)
        {
            if (e.TotalRowCount > 0)
            {
                RadScheduler1.GroupBy = "Resources";
            }
            else
            {
                RadScheduler1.GroupBy = "";
            }
        }

But TotalRowCount here is -1 ... for some reason. In Simon example he counts appointments but what I need is count number of existing employees to group appointments by them. I have no problems when there are some employees in the data source, but when nothing is there scheduler displayed incorrectly.
Page_Load comes  to early, so I can do this check in there.
Any advice? Thanks, Oleg.

Hello Oleg,

You can refer to this KB article where is shown how the RadScheduler_DataBound can be handled.

Hope this will help.
