Witam,

Pszepraszam za muj tragiczny Polski, jestem z Australia.

Poczebuje pomoc z DataBinding i ChangeEventHandler.

Mam windows form project z dataset i textbox, databinding ustawilem w
programie, nie pszes IDE.  Uzywam ChangeEventHandler zeby zmusic textbox do
numerowej notacji "#,##0.0"

ChangeEventHandler nie reaguje na pierwszy record, ale nastempujonce dziala
ok.  Dziwne?  Dlaczego?


.... Databinding
private void DataBindControls()
{
  textBox1.DataBindings.Add("Text", this.myDataSet, "MYTABLE.MYCOLUMN");
  textBox1.DataBindings["Text"].Format += new
ConvertEventHandler(ToNumberString);
}

.... ConvertEventHandler
private void ToNumberString(object sender, ConvertEventArgs e)
{
  // Format number.
  if (e.Value.ToString() == string.Empty)
    e.Value = DBNull.Value;  // Don't format nulls.
  else
    e.Value = ((double)e.Value).ToString("#,##0.0#####");
}


Jeszce raz pszepraszam za muj Polski, powinenem byc wyslany do wienzienia za
blendy co tutaj napisalem.

Pozdrawiam,
Peter Zyczynski
