Grouping the same Member several times.

[Martin Egger]

Hi everyone

Quick question:

Is there a way to group the same Member several times? Take a look at the following code:

                        <telerik:GridViewDataColumn Header="Jahr" DataMemberBinding="{Binding datum}" DataFormatString="{}{0:yyyy}" />
                        <telerik:GridViewDataColumn Header="Monat" DataMemberBinding="{Binding datum}" DataFormatString="{}{0:MMM}" />
                        <telerik:GridViewDataColumn Header="Tag" DataMemberBinding="{Binding datum}" DataFormatString="{}{0:dd}" />

I would like to group by Year (Jahr) and Month (Monat). Because the Member is always "datum" (date), I only can group one at a time.
Is there  a way to achieve this within or outside the RadGridView?

Hello Martin Egger,

The cleanest way to create such functionality is to define get-only property wrappers in our data model, that return the pert of the date needed. E.g.

public int Year
{
   get {return this.Date;}
}

That way there will be group descriptor for each data property.

All the best,

Hi

Thx alot. Had some problems fingering out where to implement the code. After some research it worked by creating a partial class of that particular entity.

Works fine!

 public partial class Eingang
    {
        public DateTime Jahr
        {
            get { return _datum; }
        }

        public DateTime Monat
        {
            get { return _datum; }
        }

    }
