How can we maintain the page scroll position after postback?

  1. Set PositionOnPostback as true in Page directive

  2. Set MaintainScrollPositionOnPostback as true in Page directive

  3. Set ViewState as true in Page directive

  4. Not Possible
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The MaintainScrollPositionOnPostback attribute in the Page directive preserves the scroll position across postbacks by storing it in a hidden field. This prevents the page from jumping back to the top after a server-side event. PositionOnPostback is not a valid attribute, and ViewState handles state management, not scroll position.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The statement is false because while Android applications do have multiple screens, each screen is typically implemented by a single Activity, not multiple activities. An Activity represents a single screen with a user interface. You can have multiple activities in an app, but one activity per screen is the standard pattern.

In your application, you need to display certain data in list form, but it needs to be general purpose, does not have to be data bound, and can dynamically create rows. What type of list control is best suited for the scenario above?

  1. Repeater

  2. DataGrid

  3. DataList

  4. Table

  5. TableList
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Table is the best choice for a general-purpose, non-data-bound list that needs dynamic row creation. Repeater and DataList are data-bound controls, and DataGrid requires a data source. Table (option D) provides maximum flexibility for manual row creation without data binding requirements.

  1. ItemCommand

  2. ButtonClicked

  3. OnClick

Reveal answer Fill a bubble to check yourself
A Correct answer

The DataGrid control raises the ItemCommand event when any button within the grid is clicked, including custom buttons. This server-side event is specifically designed to handle button clicks in DataGrid rows. OnClick is a client-side JavaScript event, ButtonClicked is not a standard DataGrid event, and EditCommand only fires for Edit buttons specifically.

Please select the wrong statement with reference to SPLATT

  1. For each LOB, we have a project under the SPIAcceptanceTests.sln

  2. The xml scripts are written using Visual Studio 2005.

  3. SPLATT can be used for Mainframe testing

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The wrong statement is C because SPLATT is designed for SPL (Service Level) testing, not Mainframe testing. Options A and B describe correct aspects of SPLATT: it has projects for each LOB and uses XML scripts in Visual Studio.

C Correct answer
Explanation

The question asks for the WRONG statement about SPLATT. Options A and B describe true facts about SPLATT (it has projects under SPIAcceptanceTests.sln for each LOB, and uses XML scripts in Visual Studio 2005). Option C says 'SPLATT can be used for Mainframe testing' - if this is FALSE (making it the wrong statement), then SPLATT cannot be used for mainframe testing, which is plausible if SPLATT is specifically for distributed systems testing. Option D 'All of the above' cannot be correct if we're looking for a single wrong statement.
