Bindingsource not updating
Second reason is that the Application Bar control can’t get focus, nor can it’s Application Bar Icon Button or Application Bar Menu Item controls, so when you tap on them, the click event will be invoked without the Text Box control ever loosing focus!
To fix this behavior we need to force an update on the binding source when the click event get’s invoked, and here’s some code on how to achieve this: We start by using Focus Manager.
With WPF this is done easily by setting the Update Source Trigger property to Property Changed in the Binding definition, unfortunately this is not available for Silverlight.
A workaround that I found for this was to add a Key Up event to the required Text Box and update the binding in code behind.
Note: if you want to manipulate the database directly with code, you could avoid Binding Source as well as the other mentioned objects. NETDownload a file from a website in Visual Basic .

Typically you attach the Binding Source to a data source and then you bind controls to the Binding Source.
When the Binding Source changes its position in the data source, it automatically updates the bound controls. NETWrite Or Insert Records to Access (2007) Database Table - Visual Basic .
Thus, the property in the code has to raise a property Change event in order to notify the //create the Text Field var text Field Module = require("ui/text-field"); var target Text Field = new text Field Module.Text Field(); //create the Label import label Module = require("ui/label"); var target Label = new label Module.Label(); After that, the target objects bind to the source object.For example, say that your Data Grid View is initially filled with some data.
When you request sorting of a column, the Data Grid View control will communicate that intention to the Binding Source, which in turn communicates that intention to the data source. NET 2005 and C#, i have binded two text boxes with data Table named dt. Data Source = dt;it also Works fine; NOW, when it comes to updating. NET 2003 C# it worked perfectly, and the same code does not work in VS. I am trying for several days now, but could'nt fix this problem.
