The shortcut for Project... (Ctrl-Shift-N) is actually (Ctrl-N) in the software

The shortcut for File... (Ctrl-N) does not exist in the software

I'm using the latest VS 2005 IDE and it doesn't have an onChange event for the asp:TextBox web control. However; it does contain an OnTextChanged event handler. Not sure what the event is called with the express ide but wanted to pass this alone....

<asp:TextBox ID="TextBox1" runat="server" OnChange="javascript:DoChange();"></asp:TextBox>

CellPadding and CellSpacing have identical descriptions. Is this deliberate or accidental?

I think I found a minor bug in BulletedListDemo code (p. 145).

'NotSet' doesn't appear to be a legal value for the BulletedListDisplayMode. However, it's a choice in the DisplayMode listbox. If 'NotSet' selected the following error occurs:

Server Error in '/BulletedListDemo' Application.
--------------------------------------------------------------------------------

Requested value 'NotSet' was not found.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: Requested value 'NotSet' was not found.

The drop down list (example 4-36) should contain a list item with text "Middle" between "Baseline" and "TextTop". The code-behind (example 4-37) seems to assume that entry is in the drop down list.

The coordinates for the final PolygonHotSpot should probably begin with 4,265,... rather than 495,45,... It would more accuratley reflect the area underneath the band.

Wizard control is called "Wizard1" here but referred to as "wzzrdMorning" in rest of text and code for this demo.

"A call is made to the lblSelectedUpdate method to clear the Label control containing the first selected date...."

The above doesn't occur with the downloaded Calendar-MoreSelections code. The label doesn't get cleared.

I had to add the following to the end of the lblSelectedUpdate() method to get it to work:
if (Calendar1.SelectedDates.Count == 0)
lblSelected.Text = "";

Text in book:
"Page-Level Tracing........but the SessionID remains constant."

I'm following the examples in the book by creating new web sites in my local file system (as preferred by the book). My Session ID changes everytime the page is posted back to the server. Perhaps this wouldn't happen if IIS were serving the page.

The Page directive does not include the ClientTarget attribute (as referenced on page 325). Therefore the btnSubmit_Click function (bottom page 331) will never execute until the page is completely valid (or the application is running in a "downlevel" browser). The means the "Some of the required fields are empty" string is never displayed in lblMsg.

Text:
"You will be asked to update your grid, which unfortunately will wipe out all your customization...."

This didn't happen when I tried it. My customizations remained.

Text:
"....change from Edit and Delete to Save and Cancel."

They change to Update and Cancel.

The NULL data in the Region column caused an exception and wouldn't allow updating if Optimistic Concurrency was turned on. I'm not sure why this happened.

My version of the page wont save any updates as long as optimist concurrency is selected. When this is unselected as an option, the page works fine.

Text:
"The DataGrid allows you to...."

I think you meant the "GridView".

Book Text:
"(replace the control and the ID)"

It doesn't seem necessary to replace the ID. The ID is already correct.

Book Text:
"<h1> Form View Display</h1>

Should be "<h1> Product View Display</h1>" as this is how it appears in remaining examples.

The DataRelations code example doesn't include the !IsPostBack check in the Page_Load method.

Book Text:
"// and add the table mapping for bugs

What is "bugs"? I believe this should be "Orders".

What is the reason for creating a third data adaptor that maps to the 'Products' table when this DataTable is never bound to a GridView?

Book Text:
"// and add the table mapping for bugs"

"bugs" should be "Shippers"

Book Text:
"// end createDataSet"

"createDataSet" should be "PopulateGrid"

Book Text:
"// connection string to connect to the Bugs database"

Should be:
"// connection string to connect to the Northwind database"

Book Text:
"// set up the command object to update the bug history"

Should be deleted.

Book Text:
"// create a second command object for the bugs history table"

Should be:
" // declare the command object for the sql statements"

Book Text:
"Create two new .aspx pages, Welcome.aspx and PageTwo.aspx."

Should be:
"Create two new .aspx pages, Welcome.aspx and SecondPage.aspx."

Book Text:
"When you create SecondPage.aspx,...."

Should be:
"When you create PageTwo.aspx,....."

Book Text:
"..as shown in the highlighted lines of code in Example 12-2"

Not enough lines have been highlighted in Example 12-2.

Book Text:

CodeFile="ASP.NET.master.cs"

I believe it should instead be:

CodeFile="ASPNET.master.cs"

Book Text:
"...(shown highlighted in Example 12-2)"

Book Text:
"To begin with, you may click the Smart Tag....."

I needed to move the TreeView control out of the table before it became visible in Design view.

Programming.aspx in downloaded source files has AutoEventWireup="false" which doesn't allow the Page_Load to handle the event in Programming.asp.cs.

In example 3-12 the text boxes are renamed, but the save_Click method shown on page 563 still references the original names.
