, as a child of a parent BO.
The parent can have many notes records, like an activity list.
The interface shows old notes as Read Only (formated in a label) and allows appending a new note from a textBox. The formatting requires (so far as I can see) non-binding controls.
I want to have the child save participate in the parent save transaction. But it's tricky.
1)----------------------------------------
To add, I'm doing:
public static void AppendNote(mmBindingList<NoteEntity> eNotes,
string s)
{
if (!mmUtils.Empty(s))
{
NoteEntity note = eNotes.AddNew();
note.someString = s;
eNotes.EndNew(eNotes.Count);
}
} But when I go to save, the BO DataSet isn't changed.
This (below) works, but is there a better way to do it?public static void AppendNote(mmBindingList<NoteEntity> eNotes,
NoteBusinessObject oNote,
string s)
{
if (!mmUtils.Empty(s))
{
NoteEntity note = eNotes.AddNew();
note.SetDataRow(oNote.NewRow()); // NEW code to set row *******
note.someString = s;
eNotes.EndNew(eList.Count)
}
} 2)----------------------------------------
The save code, if NOT mmSaveDataResult.RulesPassed, has to roll back the note.
public class NoteUI
{
public static int AppendNote(mmBindingList<NoteEntity> eNotes,
NoteBusinessObject oNote,
string s)
{
int count = 0;
if (!mmUtils.Empty(s))
{
NoteEntity note = eNotes.AddNew();
note.SetDataRow(oNote.NewRow()); // NEW code *******
note.someString = s;
eNotes.EndNew(eList.Count);
count = eList.Count;
}
return count;
}
}
private void DoBasicSave()
{
int noteCount = NoteUI.AppendNote(eNotes, oNote, this.txtComments.Text);
mmSaveDataResult saveResult = this.Save(this.oParent, this.dsParent);
if (saveResult == mmSaveDataResult.RulesPassed)
{
Response.Redirect("default.aspx");
}
else
{
if (noteCount > 0)
{
eNotes.RemoveAt(noteCount);
}
}
}I would imagine this is a somewhat common problem. Anyone have a better way to do it?
(I'm not going to use a GridView...)
Thanks!
