I cannot get a DateTimeEditorProvider to properly display just hour:minute in Edit Mode.
I added a date/time column to Products table in the Northwind database.
I modified the ReadOnly sample and added a date/time column. 
I added a DateTimeEditorProvider and assigned it to the new date/time column.
I need the Edit format to display hours:minutes. 
However in each of my attempts, it will display the month/day as hour:minute.
Here is my code:
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
    <div>
        <ig:WebDataGrid ID="WebDataGrid1" runat="server" Height="500px" Width="800px" DataKeyFields="ProductID"
            DataSourceID="AccessDataSource1" AutoCRUD="false" AutoGenerateColumns="false">
            <EditorProviders>
                <ig:DateTimeEditorProvider ID="WebDateTimeEdit1" runat="server"
                    EditorControl-DisplayModeFormat="{0:g}"
                    EditorControl-EditModeFormat="t">
                </ig:DateTimeEditorProvider>
            </EditorProviders>
            <Columns>
                <ig:BoundDataField DataFieldName="ProductID" Key="ProductID" Width="100px" Header-Text="Product ID"></ig:BoundDataField>
                <ig:BoundDataField DataFieldName="ProductName" Key="ProductName" Width="100px" Header-Text="Product Name"></ig:BoundDataField>

                    DataFormatString="{0:g}" DataType="System.DateTime"
                    Header-Text="Discontinued Date">
                </ig:BoundDataField>
            </Columns>

                            </ColumnSettings>
                            <EditModeActions MouseClick="Single" />
                        </ig:CellEditing>
                    </Behaviors>
                </ig:EditingCore>
            </Behaviors>
        </ig:WebDataGrid>
    </div>
