1. You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
You create a Web page that contains the following two XML fragments. (Line numbers are included for reference only.)
01 <script runat="server">
02
03 </script>
04 <asp:ListView ID="ListView1" runat="server"
05  DataSourceID="SqlDataSource1"
06 ?
07 ?>
08 <ItemTemplate>
09   <td>
10     <asp:Label ID="LineTotalLabel" runat="server"
11      Text='<%# Eval("LineTotal") %>' />
12   </td>
13 </ItemTemplate>
The SqlDataSource1 object retrieves the data from a Microsoft SQL Server 2005 database table. The database table has a column named LineTotal.
You need to ensure that when the size of the LineTotal column value is greater than seven characters, the column is displayed in red color.
What should you do?
A. Insert the following code segment at line 06.
OnItemDataBound="FmtClr"
Insert the following code segment at line 02.
protected void FmtClr
(object sender, ListViewItemEventArgs e)
{
  Label LineTotal = (Label)
  e.Item.FindControl("LineTotalLabel");
  if ( LineTotal.Text.Length > 7)
  { LineTotal.ForeColor = Color.Red; }
  else
  {LineTotal.ForeColor = Color.Black; }
}
B. Insert the following code segment at line 06.
OnItemDataBound="FmtClr"
Insert the following code segment at line 02.
protected void FmtClr
(object sender, ListViewItemEventArgs e)
{
  Label LineTotal = (Label)
  e.Item.FindControl("LineTotal");
  if ( LineTotal.Text.Length > 7)
  {LineTotal.ForeColor = Color.Red; }
  else
  {LineTotal.ForeColor = Color.Black; } ?
}
C. Insert the following code segment at line 06.
OnDataBinding="FmtClr"
Insert the following code segment at line 02.
protected void FmtClr(object sender, EventArgs e)
{
  Label LineTotal = new Label();
  LineTotal.ID = "LineTotal";
  if ( LineTotal.Text.Length > 7)
  {LineTotal.ForeColor = Color.Red; }
  else
  { LineTotal.ForeColor = Color.Black; }
}
D. Insert the following code segment at line 06.
OnDataBound="FmtClr"
Insert the following code segment at line 02.
protected void FmtClr(object sender, EventArgs e)
{
  Label LineTotal = new Label();
  LineTotal.ID = "LineTotalLabel";
  if ( LineTotal.Text.Length > 7)
  {LineTotal.ForeColor = Color.Red; }
  else
  {LineTotal.ForeColor = Color.Black; }
}
Answer: A

2. You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
You create a Web form and add the following code fragment.
<asp:Repeater ID="rptData" runat="server"
 DataSourceID="SqlDataSource1"
 ItemDataBound="rptData_ItemDataBound">
  <ItemTemplate>
    <asp:Label ID="lblQuantity" runat="server"
     Text='<%# Eval("QuantityOnHand") %>' />
  </ItemTemplate>
</asp:Repeater>
The SqlDataSource1 DataSource control retrieves the Quantity column values from a table named Products.
You write the following code segment to create the rptData_ItemDataBound event handler. (Line numbers are included for reference only.)
01 protected void rptData_ItemDataBound(object sender,
02 ?RepeaterItemEventArgs e)
03 {
04  
05   if(lbl != null)
06   if(int.Parse(lbl.Text) < 10)
07   lbl.ForeColor = Color.Red;
08 }
You need to retrieve a reference to the lblQuantity Label control into a variable named lbl.
Which code segment should you insert at line 04?
A. Label lbl = Page.FindControl("lblQuantity") as Label;
B. Label lbl = e.Item.FindControl("lblQuantity") as
 Label;
C. Label lbl = rptData.FindControl("lblQuantity") as
 Label;
D. Label lbl = e.Item.Parent.FindControl("lblQuantity") as
 Label;
Answer: B
