Interview Questions And Answers

ASP.NET UpdatePanel controls enable you to build rich, client-centric Web applications. By using UpdatePanel controls, you can refresh selected parts of the page instead of refreshing the whole page with a postback. This is referred to as performing a partial-page update. An ASP.NET Web page that contains a ScriptManager control and one or more UpdatePanel controls can automatically participate in partial-page updates, without custom client script.

Answer: A view is created by joining one or more tables. When you update record(s) in a view, it updates the records in the underlying tables that make up the view.

So, yes, you can update the data in a view providing you have the proper privileges to the underlying tables.

1) When you want to pass value/object to another page you can use this session object.

2) When you want to save (temporary) some data for that particular user , you can use this session object. Eg., Passing login information of the user from one page to another

There are three locations where a session can be stored :

1)InProc : If you set this mode, then session is stored in Web Server worker process(aspnet_wp.exe). This is by default and the performance is fast because it resides in the same worker process.

2)StateServer : If you set this mode, then session is stored in a separate process in the server called aspnet_state.exe.

3) SqlServer : If you set this mode, then session is Stored in SQL Server.

MediaPlayer player = new MediaPlayer();

player.Open(new Uri("music.wma", UriKind.Relative));

player.Play();

The following code shows how to use SoundPlayer to play

Shape's Fill and Stroke properties have the same role as GeometryDrawing's Brush and Pen properties: Fill is for the inner area, and Stroke is for the outline. Internally, a Pen is indeed used to create the outline of the Shape. But rather than exposing the Pen directly, Shape defines Stroke as a Brush and exposes eight additional properties to tweak the settings of the internal Penwrapping the Stroke Brush: StrokeStartLineCap,StrokeEndLineCap, StrokeThickness, and so on.
This unfortunate inconsistency was created because setting the Pen-related properties directly on the Shape is simpler than using a separate Pen object, especially for the common case in which all you're setting is the Brush and the Thickness.
