Bindingsource not updating

It also has a datagrid1 and a bunch of other controls and they're all bound to the table1bindingsource.There is no binding navigation on this form A, the user is allow to navigate using the datagrid1, edit the data using the controls. , the actual databinding mechanics are much nicer in . For one the new controls manage typed values much nicer with some basic inputmasking to match the type.There's a Value property which looks like this: I'm probably missing something obvious, but after searching around for an hour today and running into lots of small pieces I still haven't found a resource that explains how the Binding Source actually hooks up the values.I'm not entirely convinced that this disconneced state is any advantage since all my clients have Hi all, I'm quite new to vb 2005 and need some help: I have 2 forms say form A and form B, form A has a dataset1, table1adapter & table1bindingsource (backend database is access).

However, the values are null, because the current value of the bindingsource is null at that point... Nullable(Of Date Time) Get Return _startdate End Get Set(By Val value As System. NET section with ID#240723 with much more detail if you're interested. If I visited the tab w/ the datepickers first all was working was driving me up the wall for a good couple of hours, thanks again for posting this. I need to develop an user control (MTbl Stadr) with a datagridview, the problem si that Idon't know how to do for the MTbl Stadr control be able to asign a datasource in design time... Instead of setting properties, you handle events that call your own business logic.Then somewhere the Data Table would be updated i.e.say you contacted some Web Service or whatever else you want, to get the new Data Table.You can also change the Data Source of Binding Source and the binding will work fine.Hi all, I'm quite new to vb 2005 and need some help: I have 2 forms say form A and form B, form A has a dataset1, table1adapter & table1bindingsource (backend database is access).However, looks like I have another related problem now though: I can't seem to find an event to hook to do the dynamic calculations where the Entity object is already updated.I'm using the Validated and in this event the Entity is not updated.Again it's only the User Control that exhibits this behavior - the stock controls work fine here.With the flock of Borland engineers that have gone to MS over the years I am a little surprised that Winforms databinding is so lame. I am using a User Control, which is supposed to load another dataset automatically when a Bindable Property is updated...Specifically what triggers the On Validation or On Property Changed operations that presumably update the control and underlying data sources. The correct url is: To Market/Data Binding/Data Binding Hmmm... I've already been implementing a Value Changed event unbeknownst to the fact that this is supposed to provide the change notifications. Implementing INotify Property Change does the trick though.INotify Property Change seems to update the control values.
