Hi,
I have a form with four Combo whose DataSource and DisplayMember is the
same. The problem is that when I select a value from a combo all other
combo start displaying same value. I have not used any
BindingContextManager on the form. (I am using C#)
* If you are using NET2.0, then set a different BindingSource between them:
ComboBox1.DataSource = new BindingSource(dv,"");
ComboBox2.DataSource = new BindingSource(dv,"");
etc....
* If you are using NET1.1, then there are a few options :
1. Use a different DataView of the same DataTable for each ComboBox:
ComboBox1.DataSource = new DataView( someTable );
ComboBox2.DataSource = new DataView( someTable );
2. Use a different BindingContext, i don't recommend this option because it
_will cause problems_ when you also bind the ComboBox's Text,
SelectedValue, etc to another DataTable.
ComboBox1.BindingContext = new BindingContext();
ComboBox1.DataSource = dv,
ComboBox2.BindingContext = new BindingContext();
ComboBox2.DataSource = dv,
3. Create a simple ListWrapper:
public class ListWrapper : IListSource
{
private IList list;
public ListWrapper( IList List )
{
list = List;
}
public bool ContainsListCollection
{
get { return false; }
}
public IList GetList()
{
return list;
}
}
ComboBox1.DataSource = new ListWrapper( dv );
ComboBox2.DataSource = new ListWrapper( dv );
HTH,
Greetings
