I have a column with which get's edited using the ListViewDateTimeEditor.

The question is, how do I format the value that gets submitted to the ListView.

To be clear, I have already formatted the ListViewDateTimeEditor to use the following: 

Dim Editor As New ListViewDateTimeEditor
TryCast(Editor.EditorElement, BaseDateTimeEditorElement).Format = DateTimePickerFormat.Custom
TryCast(Editor.EditorElement, BaseDateTimeEditorElement).CustomFormat = "MM/dd/yyyy"
e.Editor = Editor

 

Even with this formatting, it still submits the full DateTime to the ListView when finished editing.  How do I make it output only the formatted Date value, without the Time?

Not sure if it's the proper way, but I figured out at least one way to do it.

I captured and processed it in the ListView's ItemEdited event.

Private Sub lvEquip_ItemEdited(sender As Object, e As ListViewItemEditedEventArgs) Handles lvEquip.ItemEdited
    If e.VisualItem.Data.ListView.CurrentColumn.Name = "Col23" Then
        Dim DT As DateTime
        DateTime.TryParse(e.VisualItem.Data("Col23"), DT)
        e.VisualItem.Data("Col23") = DT.ToShortDateString
    End If
End Sub

Hi Brandon,

Your appraoch is ok if you are storing the data as a string. If you are storing a DateTime object you can use the CellFormatting event and change the text of the cell which would not affect the actual value:
Private Sub RadListView1_CellFormatting(ByVal sender As Object, ByVal e As ListViewCellFormattingEventArgs)
    Dim cell As DetailListViewDataCellElement = TryCast(e.CellElement, DetailListViewDataCellElement)
    If cell IsNot Nothing AndAlso cell.Data.Name = "Date" Then
        Dim value As Date = CDate(cell.Row("Date"))
 
        cell.Text = value.ToShortDateString()
    End If
End Sub

I hope this will be useful. Let me know if you have additional questions.

Regards,
