Question: You work as a Web Developer at Company.com. You are in the process of creating a Web application that uses Microsoft ASP.NET 3.5. A page in the Web application will permit clients to dynamically configure its layout. Clients are able to add user controls to the page dynamically by clicking a Button control on the pag

public partial class PortalPage : System.Web.UI.Page
{
private int _sectionCount = 0;
protected void AddButton_Click(object sender, EventArgs e)
{
Control control = this.Load("Section.ascx");
Controls.Add(control);
_sectionCount++;
}
} 

You receive an instruction from the CIO to make sure that the page retains the dynamically-added user controls as it undergoes post-back requests. You need to ensure that the solution does not permit a configuration change in order to override this functionality. What should you do? (Choose all that apply)

1. You should use the code segment:
   protected override LoadViewState(object savedState)
   {
   _sectionCount = (int)savedState;
   }
2. You should use the code segment:
   protected override object SaveViewState()
   {
   ViewState[“SectionCount”] = _sectionCount;
   }
3. You should use the code segment:
   protected override void LoadControlState(object savedState)
   {
   Pair pair = (Pair)savedState;
   base.LoadControlState(pair.First);
   _sectionCount = (int)pair.Second;
   for (int index = 0; index < _sectionCount; index++)
   {
   Control control = this.LoadControl(“Section.ascx”);
   Controls.Add(control);
   }
   }
4. You should use the code segment:
   protected override object SaveControlState()
   {
   Pair pair = new Pair();
   pair.First = base.SaveControlState();
   pair.Second = _sectionCount;
   return pair;
   }
5. You should use the code segment:
   protected override void OnInit(EventArgs e)
   {
   Page.RegisterRequiresControlState(this);
   base.OnInit(e);
   }

Question: You work as a Web Application Developer. You are in the process of creating an ASP.NET application that uses Microsoft .NET Framework 3.5. You decide to create a custom Web user control for the application. You name this control TestShar

<%@ Master Language="VB" EnableViewState="false" %> 

You receive an instruction from management to make sure that the state of TestShare is accessible on the subsequent pages that reference a master pag

1. You should consider adding Page.RegisterRequiresControlState(Me).
2. You should consider adding Page.UnregisterRequiresControlState(Me).
3. You should consider adding Page.RegisterStartupScript(“TestShare”, “server”).
4. You should consider adding Page.RegisterRequiresPostBack(Me).

Question: You work as a Web Application Developer at Company.com. You make use of Microsoft .NET Framework 3.5 to create an ASP.NET application. Your application contains a class with the code below:

public object GetAllOrders(sqlConnection cnn) {
if (Cache["orders"] == null) {
SqlCommand cmd = new SqlCommand("SELECT * FROM Orders", cnn);
cnn.Open();
Cache.Insert("orders", GetData(cmd));
cnn.Close();
}
return Cache["orders"];
}
public object GetOrderData(SqlCommand ordCmd) {
// insert code here
} 

You notice that the GetAllOrders method is called to provide this list from the Cache object every time a Web form has to access a list of products. To ensure productivity management wants you to make sure that there is always a list of products available in the Cache object. What should you do?

1. Your best choice would be to add the code:
   public object GetOrderData(SqlCommand ordCmd) {
   return ordCmd.ExecuteReader();
   SqlDataReader datareader;
   ordCmd.CommandTimeout = int.MaxValue;
   }
2. Your best choice would be to add the code:
   public object GetOrderData(SqlCommand ordCmd) {
   datareader = ordCmd.ExecuteReader();
   return datareader;
   }
3. Your best choice would be to add the code:
   public object GetOrderData(SqlCommand ordCmd) {
   SqlDataAdapter dadtp = new SqlDataAdapter();
   dadtp.SelectCommand = ordCmd;
   DataSet dset = new DataSet();
   return dset.Tables[0];
   }
4. Your best choice would be to add the code:
   public object GetOrderData(SqlCommand ordCmd) {
   SqlDataAdapter dadtp = new SqlDataAdapter(ordCmd);
   DataSet dset = new DataSet();
   dadtp.Fill(dset);
   return dset;
   }
