Errata

Bing is not returning an error code of 200 as stated in the book.

Session("masterpage") = "~Master2.master"

should read

Session("masterpage") = "~/Master2.master"

<link href="SiteStyles.css" rel="themeName/stylesheet" type="text/css" />

should read

<link href="SiteStyles.css" rel="stylesheet" type="text/css" />

It implies that if you added controls dynamically in PreInit then you don't need to call ApplyStyleSheetSkit. But that's not the case. I don't need to call ApplyStyleSheetSkit in any of PreInit, Init, or Load when I use Theme & inversely I have to call in all 3 event handlers if I use StyleSheetTheme. Sorry dear but I think I'm right. :)

The cast is not needed.

mode="Off", not mode="off"

SHOULD BE

BOTH THE EXTRA PAIR OF PARENTHESES & THE CAPITAL "S" ARE NECESSARY

All instances of <br> should be replaced with <br /> so the output page generates valid XHTML?

MaxRequestLength

should read

maxRequestLength

(error in two places)

Paragraph 2 refers to HttpServerUtility class and the MapPath method.

This does not agree with the code example which is calling the MapPath method within the Page class itself.

The code should probably use Server.MapPath() to agree with paragraph #2 on page 203

RangeValidatorSalesDate.MinimumValue = "1900"()

should read

RangeValidatorSalesDate.MinimumValue = "1900"

Disregard my last errata post for this page as it is incomplete. The "1900" value throws an error.

This should be a complete date. However the example does not do what the paragraph suggests it should do - 1900 does not represent the "current" year.

The C# code should look something like:

RangeValidatorSalesDate.MinimumValue = new DateTime(DateTime.Now.Year, 1, 1).ToShortDateString();

RangeValidatorSalesDate.MaximumValue = new DateTime(DateTime.Now.Year, 12, 31).ToShortDateString();

This would give the range of the whole current year.

VB code would need same sort of fix

"ClientFunctionName property of the CustomValidator control" should say "ClientValidationFunction property of the CustomValidator control" .

The for loop in code samples has a logic error:
if (uc && lc && num) {
arguments.IsValid = true;

The sample code has a logic error:
/// pp. 237-238
if (uc && lc && num) {
arguments.IsValid = true;
break;
}
/// p. 240
if (uc && lc && num)
{
// must be valid
args.IsValid = true;
break;
}
If the first three or more characters satisfy the conditions, the loop will exit, regardless of any remaining characters. To handle the validation correctly, a fourth "else" clause is needed, and the "break;" statement moved there. Thusly:

else {
arguments.IsValid = false;
break; // the loop will exit on the first invalid character with condition of false
}

if (uc && lc && num) {
arguments.IsValid = true;
} // the loop will continue until the end of the string

The statement "var data = arguments.Value.split(' ');" creates an array called "data" with the value of the entered password string split into substrings, if there are any blanks in the password. Each substring is put in an element of the array. If there is no blank in the password, the whole password string is put in element "data[0]".

The problem is that the test of "data.length" further down in the code does not test the length of the first element of the array "data", but the number of elements in it. This means that if one enters a password such as "Mas123", which is valid in the example, "data" will contain only an element "data[0]" equal to "Mas123", and "data.length" will be equal to 1 (the number of elements), rather than 6 (the length of the password).

I used the following code instead, and it worked:

"var ArgArray = arguments.Value.split(' ')
var data = ArgArray[0]"

With this code, "data.length" is now correct for the subsequent code.

The last paragraph says "To implement server-side validation with the CustomValidator control, handle its ServerValidate event." However, nothing is said about setting the CustomValidator control's OnServerValidate property to define the name of the event handler in the code-behind file.

The OnServerValidate property should be included.

"Notice that the code sample catches a ThreadAbortException after calling System.Transfer. " should be changed to "Notice that the code sample catches a ThreadAbortException after calling Server.Transfer."

Use Server.Transfer instead of System.Transfer.

The ID's for the WebPartZone controls are of format TopWebPartZone, LeftWebPartZone, ... in the explaining text, but in the code sample ID's such as WebPartZoneTop and WebPartZoneLeft are used

Two instances where ZoneTemplate is described as a control.

MSDN describes this as a property

Surely "tag" would be a better choice of words?

VB

Dim browseModeName As String = webPartManager.BrowseDisplayMode.Name

C#
String browseModeName = WebPartManager.BrowseDisplayMode.Name;


These 2 lines seem to do absolutely nothing. browseModeName is not used; these lines could be removed I think


Also, generally messy code - nicely camelCase until _manager is declared.

<%@ Page uiculture="es" culture="es-MX" %>

should read

<%@ Page UICulture="es" Culture="es-MX" %>

I can't make the example work if Address in the templated user control is not initialized first.

I could make it work ok when I did in the code page 343

//I added this to initialise.... before setting up the container
this.Address = new Adress();

AddressUcContainer container = new AddressUcContainer (this.Address);

If we don't do that,
We get a mistake with NullReference exception when we use the control in the init event of the page using this control:

// Boom!!! Address is set to null...
AddressUcTemplated1.Address.AdddressLine1

the url of trace page

http//server/application/trace.axd give me a 404 error

the url of the trace can be find editing the url in browser with trace.axd

(u can see it in fig. 8-10)

Paragraphs suggests ChildrenAsTriggers="True" will cause nested UpdatePanel contols to update their parent.

this is not correct, see MSDN

Quote:
Set the ChildrenAsTriggers property to true if you want postbacks from immediate child controls of the UpdatePanel control to cause an update of the panel's content. Child controls of nested UpdatePanel controls will not cause an update of the parent UpdatePanel control's content unless you call the Update method explicitly or you define the child controls as triggers.
End Quote

In the sample code, the "innerText" property should be replaced by the "innerHTML" property make it work in other browsers (like Firefox).

Also, the text

@"var passLen = document.forms[0].MainContent_
TextBoxPassword.value.length;");

should be split in another place (ie after a dot) because it generates a script error. It sais that it cannot find the "TextBoxPassword" control.

If you want to take into accout the passwords that have 6 to 9 characters, you should change the last if to
"else if (passLen >= 6) {"

The comparison of the two string objects in the AllowPasswordChange javascritpt method is not valid.

The comparison is made on the objects and not on their value.
The two String objects (pass1 and pass2) have different reference addresses. Thus, the comparison "pass1 == pass2" will always be false, even when the two object contain the same value.

The "if " statement should be:
if (pass1.valueOf() == pass2.valueOf())
or
if (pass1.toString() == pass2.toString())

this.innerHTML = "Section " + index
should be
this.innerHTML += "Section " + index
as in the description above it says that the code appends a sequential section ID.

Note that this code uses the .click() method to define a binding to the validateEmpId
JavaScript function. The .click() method is a shortcut. You could also call .bind("click",
"validateEmpId").


Modifying the code to NOT use the .click() shortcut method will result in a javascript error. In IE9, the error is as follows: Microsoft JScript runtime error: Unable to get value of the property 'guid': object is null or undefined:

The "validateEmpId" should not be in quotes.

working jquery call:
$("#MainContent_ButtonSearch").bind("click", validateEmpId );

Note from the Author or Editor:
Need more info. Sent email.

Some browsers return an error with these lines of code...
Else
Response.Write("File not found")
End If

Due to the earlier line...
context.Response.ContentType = "image/jpeg".

Simple workaround is to do the following...
Else
context.Response.ContentType = "text/html"
Response.Write("File not found")
End If

The C# code may benefit from a similar change.

In the 2nd paragraph for the WebMethodAttribute Class it says :
"You can assign the WebMethod attribute to a class..."

It should say :
"You can assign the WebMethod attribute to a method"

In step 5, it reads "Open IShipperService.vb (or IShipperService.cs)"

It should read, "Open ShipperService.vb (or ShipperService.cs)"

Step 7 describes adding code to the IShipperService.vb / IShipperService.cs files.

The C# GetPagedCustomersSorted method doesn't consider the case of a descendin sorting.
In this case, the sortCol parameter might have a value similar to '"CompanyName DESC" and the Linq query will fail and will throw an ArgumentException.

The Linq query from the book is:

var dsSort = from cust in ds.Tables["customers"].AsEnumerable()
orderby cust.Field<string>(sortCol)
select cust;

It should be replaced with:

bool desc = sortCol.EndsWith(" DESC", StringComparison.InvariantCultureIgnoreCase);
OrderedEnumerableRowCollection<DataRow> dsSort = null;

if (desc)
{
sortCol = sortCol.Substring(0, sortCol.Length - 5);
dsSort = from cust in ds.Tables["customers"].AsEnumerable()
orderby cust.Field<string>(sortCol) descending
select cust;
}
else
{
dsSort = from cust in ds.Tables["customers"].AsEnumerable()
orderby cust.Field<string>(sortCol) ascending
select cust;
}

Similar changes should be made for the VB code.

The CommandText property of the second EntityDataSource example contains a '>' character.
It should be replaced by '&gt;' in order for the code to be built.

Change;
<asp:EntityDataSource ID="EntityDataSource1" runat="server"
ConnectionString="name=NorthwndEntities"
DefaultContainerName="NorthwndEntities"
CommandText =
"Select o.OrderId as Id, o.UnitPrice, o.Quantity,
o.UnitPrice * o.Quantity as LineItemTotal
from OrderDetails as o
where o.Discount > 0
order by o.ProductId">
</asp:EntityDataSource>

to:
<asp:EntityDataSource ID="EntityDataSource1" runat="server"
ConnectionString="name=NorthwndEntities"
DefaultContainerName="NorthwndEntities"
CommandText =
"Select o.OrderId as Id, o.UnitPrice, o.Quantity,
o.UnitPrice * o.Quantity as LineItemTotal
from OrderDetails as o
where o.Discount &gt; 0
order by o.ProductId">
</asp:EntityDataSource>

The character '>' should not be used in the declarative clauses of the EntityDataSource control.

On page 705, the Where clause is set to:
Where="it.Discount > 0"
It should be:
Where="it.Discount &gt; 0".

On page 706, the Where clause is set to:
Where="(it.Quantity * it.UnitPrice) > @OrderValue"
It should be:
Where="(it.Quantity * it.UnitPrice) &gt; @OrderValue"

The function name should be changed in both code samples from Details() to Detail() to match the action ('Detail') in the URL.

Further down in the text
controller action method (Details)
should read
controller action method (Detail)

return View("Edit", emp.EmployeeID);

should read

return View("Edit", emp);

...because the view is expecting an Employee not an int.

It says that user input won't be available. That's not true. Strictly speaking. I.e. Also considering that input of dynamically added controls is not available by referring to their IDs like the static ones anyway & that you have to use FindControl method of the container control.

Header for question 1 says answers B & D are correct, however the discussion for answer D then says Incorrect. D should be marked as Correct.
