DataBinding problem

[Martin]

Hello,

i written a collection which holds instances of a specifc class. i added a
binding like that

textBox1.DataBindings.Add("Text", ((MyClass)oMyCollection[1],
"Description");

If the content of the textbox changed, the values are saved in the object of
the collection where the controls is bound to. my problem is that other
controls don't refresh their data. so if i change the value of a property in
my instance. the control still holds the old value. i tried the following:

this.BindingContext[((MyClass)oMyCollection[1],
"Description"].EndCurrentEdit();

but it wasn't the solution. any ideas?

You are binding to a single object which isn't a problem. But then your
"object" must have a <PropertyName>Changed event for each property, like:

public class MyClass
{
private string name;

public event EventHandler NameChanged;

public string Name
{
get
{
return name;
}
set
{
if ( name != value )
{
name = value;
if ( NameChanged != null )
NameChanged( this, EventArgs.Empty );
}
}
}
}
