Hi, I have a form with for example two textboxes bound via BiningSource to my DataTable. Now everything works fine but if I try to change something manually in BindingSource.Current, the changes aren't saved in the database, for example: in buttonSave_Click(): ((DataRowView)myBindingSource.Current)["Description"] += "foo bar"; myBindi...
When using a bindingNavigator and bindingSource and clicking a move button or add button or delete button, the bindingSource completes its action code before the click handler of the button (i.e. user code) This prevents a save action on the row change. I'd like to find a bindingSource hook, something like 'beforeRowChange'. I can subc...

Hmmm - I'm using BindingSource.Find to return to the user's position after refreshing a DataGridView. I use BindingSource.Find and a RowID as the DataColumn I'm searching on. Unfortunately, Oracle can return two RowIDs that differ only in their case. BindingSource.Find returns the first match regardless of case. Looking at the MSDN ...
Hi, I'm using a BindingSource as data source for a DataGridView. The user can filter entries. Internally I use the BindingSource.Filter property of course. All works well. Then I get input from a scanner and need to select the first entry in the list that matches the scanned barcode. Whether filtered or not, the displayed list may con...

In the program we are working on, the user data is collected in UserControls which is data bound to a business entity using BindingSources.

Hello, BindingSource.AddingNew is never called when I leave the cell of my datagrid. The DataGrid has as datasource the BindingSource which again has a "List" of "Customer". What does the BindingSource need to create a new Customer object and add it to the underlying ICustomerList ? Of course a interface has no constructor... but m...

I have not been able to determine if changes made to the database are immediately seen by the binding source and then rows added/changed on the DataGridView. Environment is: VS 2008, VB.NET, database is SQLite. ...
I have noticed the following behavior, which I believe is 'wrong'. I have a BindingSource that I am using to populate a datagrid, and I am using a DataView as the BindingSource.DataSource, something like this: MyDataView = New DataView(MyTable, Filter, SortCol, _ DataViewRowState.CurrentRows) at this point in time the view is properl...
I would like to get the Type of item that a BindingSource is hooked up to or configured for. The BindingSource.DataSource property can be set to an object, list, or type. If it is a Type, it obviously does not have a bound item yet, but I would still like to get the Type. For a List, I need the item Type, not the list type. I current...
I think I understand well enough what the BindingSource class does - i.e. provide a layer of indirection between a data source and a UI control. It implements the IBindingList interface and therefore also provides support for sorting. And I've used it frequently enough, without too many problems. But I'm wondering if I use it more often ...
Hello. I'm trying to bind a ListBox's SelectedItem data to a property.

I tried to find another question like this one, since it certainly seems like something that may have been asked before; but I couldn't find it. Basically, I've got a DataGridView, which is bound to a BindingList<T>. I understand that in general, data binding is very nice and saves a lot of (our -- developers') time. However, there is a...
