Format Date Group Header

[Justin]

Hi,

I am grouping a ListView in DetailsView on a databound DateTime column. I can format the CellElement.Text for the column using the cell formatting event:

Private Sub radListView3_CellFormatting(sender As Object, e As Telerik.WinControls.UI.ListViewCellFormattingEventArgs) Handles RadListView3.CellFormatting
    If e.CellElement.Data.HeaderText = Me.RadListView3.Columns("NoteDate").HeaderText And TypeOf (e.CellElement) Is DetailListViewDataCellElement Then
        e.CellElement.Text = [String].Format("{0:D}", (DirectCast(e.CellElement, DetailListViewDataCellElement)).Row(e.CellElement.Data))
    End If
End Sub

But how can I format the group header to display the long date format as well?

Hi Justin,

Thank you for writing.

You can format the headers of the groups through by accessing them via the Groups collection or by using the VisualItemFormatting event of the RadListView:

Me.radListView1.Groups(0).Text = "My text"

Private Sub radListView1_VisualItemFormatting(sender As Object, e As ListViewVisualItemEventArgs) Handles RadListView1.VisualItemFormatting

    Dim item As DetailListViewGroupVisualItem = TryCast(e.VisualItem, DetailListViewGroupVisualItem  )
    If item IsNot Nothing Then
        item.Text = "My text"
    End If
End Sub

I hope this helps.
