Hi Dave,
When using the TwoWay binding mode, data binding does update the data in
the XmlDataProvider if the bound TextBox's text is changed. But data
binding doesn't save the changes back to the local xml file.
To save changes back to the local xml file, you can get the XmlDocument
object representing the xml file and call the Save method to save the
changes to the xml file. You can do this work in the TextChanged event
handler of the TextBox. For example:
private void textBox1_TextChanged(object sender, TextChangedEventArgs e)
{
XmlDataProvider provider =
(XmlDataProvider)this.FindResource("datarootDS");
provider.Document.Save(@"C:\demo\test.xml");
}
Hope this helps.
If you have any question, please feel free to let me know.
Sincerely,
Linda Liu
