Databinding checkbox

[Stefano Coluccia]

Hi, I'm working with compact framework on winform and a xml dataset,
the databind on textbox work fine but doen't work on checkbox that is
show the check/uncheck correctly but it doesn't save the value, what
can I do?

My sample source:
eSupCorp.DataBindings.Add("Text",oDataView,"SUPCOR PO"); // TextBox
eTatuaggi.DataBindings.Add"Checked",oDataView,"TAT UAGGI"); // Checkbox

Ho provato a salvare {"False","True"}, {"F","T"} ho provato ad
aggiungere: Format e parse ma niente da fare

private void BoolToStringa(object sender, ConvertEventArgs cevent)
{
if(cevent.DesiredType != typeof(bool)) return;
string sCheck = (string) cevent.Value;
if (sCheck.CompareTo("S") == 0)
cevent.Value = true;
else
cevent.Value = false;
}
private void StringaToBool(object sender, ConvertEventArgs e)
{
if ((e.Value is bool) && (e.DesiredType == typeof( string)))
{
bool isTrue= (bool)e.Value;
if (isTrue)
e.Value= "S";
else
e.Value= "N";
}
}

Binding bCheckBox = new Binding("Checked",oDV,"NomeCampo");
bCheckBox.Format+=new ConvertEventHandler(BoolToStringa);
bCheckBox.Parse+= new ConvertEventHandler(StringaToBool);
((CheckBoxEx)oComp).DataBindings.Add(bCheckBox);
