The following code example demonstrates using the Reset Bindings method to notify a bound control about an update in the data source.
using namespace System; using namespace System:: Collections:: Generic; using namespace System:: Component Model; using namespace System:: Data; using namespace System:: Drawing; using namespace System:: Text; using namespace System:: Xml; using namespace System:: Windows:: Forms; using namespace System:: IO; namespace System_Windows_Forms_Update Binding int main() Imports System Imports System.
When you use data-bound controls, you sometimes have to respond to changes in the data source when the data source does not raise list-changed events. Private label1 As Label Private label2 As Label Private text Box1 As Text Box Private text Box2 As Text Box Private With Events button1 As Button Private binding Source1 As Binding Source Private states As Array List Public Sub New() ' Basic form setup.
When you use the Binding Source component to bind your data source to a Windows Forms control, you can notify the control that your data source has changed by calling the Reset Bindings method.
If I use a , and then use some property of that model in the composed view's template, then the view changes properly when that property changes.
There doesn't seem to be a shorthand version of doing this.
Sometimes you need to maintain the selected row that you want to take an action on.
If you make a refresh of data in the Data Grid View the selected row will be lost, especially when you refresh data in a separate thread.

The initial data is rendered, but subsequent changes to underlaying data do not result in re-rendering of the composed component. @Eisenberg Effect, @jdanyow any idea what is going on here?
Under the hood, all component views are handled by View Strategy implementations. I also have cases where I wan to be able to easily (and.. ) very slightly modify that data: so maybe I want to simply add a '%' to the end of the data, maybe I want to do a quick calculation (), which lead me to support passing in a function.
The goal here is that I could use a composed view, or just a template, but a separate file for such a simple view seems overkill.
So, for the function example in the above plunker, if I pass in function everything will work as expected because the binding system starts watching that particular property.
