                                    <FormTemplate>
                                        <table id="Table1" cellspacing="1" cellpadding="1" border="0">
                                            <tr>
                                                <td>
                                                    Date:
                                                </td>
                                                <td>

Hello John,

One suggestion is setting the SelectedDate property of RadDatePicker from code behind when the grid is in edit mode.

VB.Net:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode AndAlso Not e.Item.OwnerTableView.IsItemInserted Then
        ' if item is about to edit
        Dim editItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
        Dim item As GridDataItem = DirectCast(editItem.ParentItem, GridDataItem)
        Dim datepick As RadDatePicker = DirectCast(editItem.FindControl("dtpCommentDate"), RadDatePicker)
        datepick.SelectedDate = Convert.ToDateTime(item("Date").Text)
    End If
End Sub

Thanks,
Princy.
