Hi,

if datasource contains date/time field, it is expanded into Year, Quater, Month, etc. Is it possible to add custom aggregate e.g. Quater of hour (15 mins interval)?

Thanks

Grouping Problem

When radGridView's data is grouped by a column and the column's HeaderText is empty string then a colon sign (:) is shown on the groups of rows in grid. How can I hide this colon sign? For more details see the attached image please.

Here is shortened code:

1.grid.Columns["Code"].HeaderText = "";

2.grid.GroupDescriptors.Add(new Telerik.WinControls.Data.GroupDescriptor("Code"));

Issue with Filters when added programmatically

I have a requirement to add a default filter to the my GridView. Therefore I do this simply using the following code:

FilterDescriptor filterDescriptor = new FilterDescriptor();
filterDescriptor.PropertyName = "DistributionStatus";
filterDescriptor.Value = "Active";
filterDescriptor.Operator = FilterOperator.IsNotEqualTo;
filterDescriptor.IsFilterEditor = true;

This is simply code taken from the documentation and modified.

This applies the restriction that I require, but when I open up the filter on screen as a user, I do not see all the values available in the column, so I am unable to remove this filter... Please see attached file (1.png) for an example.

If however, I add a random filter that does not affect the results (2.png), I now see all my available options (3.png). Can anyone suggest if this is a bug? or maybe a setting I need to update or a forced refresh of some kind?
