"Double-click btnHTML in Design view to create an event handler in the code-behind file."

Actually, double-clicking on the HTML button in the Design view does not create the event handler or the code-behind file. Instead it adds a second onclick attribute to the element in the source for the aspx file, which the previous paragraph had instructed the reader to add the attributes onclick="javascript:ButtonTest();" and onserverclick="btnHTML_ServerClick"; the second onclick attribute is set to "return btnHTML_onclick()". Here's what that element looks like after double-clicking on btnHTML in Design view:

<input id="btnHTML" type="button" value="HTML Button"
runat="server" onclick="javascript:ButtonTest();"
onserverclick="btnHTML_ServerClick"
onclick="return btnHTML_onclick()" />

Note from the Author or Editor:
Change the last paragraph of page 106 to

"Right click the page in Design view to display the code behind file for the page and add the following lines of code."

2nd paragraph of note section in middle of page

"In both cases, you'll need administrative privileges to install it, and you can accept the default options."

Well, of course, you can accept the default options, but if you do the example won't work on Vista, because by default IIS7 is installed without support for ASP.NET.

Note from the Author or Editor:
Change the final sentence of the second paragraph on p109 to

In both cases, you'll need administrative privileges to install it. XP Users can accept the default options but Vista users will also need to select ASP.NET to be installed.

The coordinates of the bottom PolygonHotSpot produce a polygon that does not align with the area in the image. It overlaps the 2nd polygon (too high) on the right side and is not high enough on the left side.

The error is in the Coordinates parameter. This segment in error is:
Coordinates="495,45,495,112,495,320,4,320"

This value should be changed to:
Coordinates="495,112,495,320,4,320,4,264"

Note from the Author or Editor:
COordinates should be changed as noted above

Code example (Ex 5-24)

The FileUploadDemo has a coupla minor issues.

In btnSave_Click() the code has an

if (FileUpload1.HasFile)
{
...
}
else {
lblMessage.Text = "No file uploaded"; // NOTE THIS LINE
}

but this is never displayed to the user because a few lines later we see:

lblMessage.Text = str.ToString().

which overrides the prior assignment. The noted line should be:

str.Append("No file uploaded.");

which will be properly reported to the user.

--

This same issue appears in btnDisplay_Click() in the same example.

---

Also in btnSave_Click, there are two outputs of the same data:

str.AppendFormat("Saved as: {0}", FileUpload1.PostedFile.FileName);
...
str.AppendFormat("PostedFile FileName: {0}", FileUpload1.PostedFile.FileName);

The first one should probably be "FileUpload1.FileName";

Note from the Author or Editor:
As stated in the submitted errata,

On p263, the line under "// show info about the file" should read
str.AppendFormat("Saved as: {0}", "<c:\\SaveDirectory>" + FileUpload1.FileName);

On p263, 7 lines up from the bottom of the page, change lblMessage.Text = "No file uploaded."; to read str.Append("No file uploaded");

On page 264, 6 lines from the bottom of the code listing, change lblMessage.Text = "No file uploaded."; to read str.Append("No file uploaded");

Last paragraph, continuing on to page 307

In the second sentence you say "Though the end result of the Response.Redirect and the cross-page post appears the same, there is a fundamental difference". The rest of the paragraph goes on comparing Response.Redirect and Server.Transfer. I believe where is says "Server.Transfer" it should say "cross-page post".

Note from the Author or Editor:
Hi,

I think I would go with this errata and make the changes as suggested. The paragraph in question applies equally in measure to both Server.Transfer and cross-page posting - hence the confusion - but in context it should be talking about cross-page posts.

When OrderGridView was added to DataRelations.aspx, its DataKeyValues property was set to OrderID. When called, the UpdateDetailsGrid method asks the OrderGridView for its DataKeys collection. This returns a collection of the fields set in DataKeyValues for the row currently selected on the GridView-or in brief, the OrderID for the order currently selected in OrderGridView.
-------------------------
The "DataKeyValues" in error line should be changed to "DataKeyNames".

Note from the Author or Editor:
Please correct as noted in the errata. p480, 2nd para.
Change "This returns a collection of the fields set in DataKeyValues for the row..." to
"This returns a collection of the fields set in DataKeyNames for the row..."

various methods in this chapter's section

in the click event handler methods of the Add and Edit buttons, you pass a value of type StringBuilder to the UpdateDB method which only accepts an argument of type string, as does the SqlCommand type, respectively. you can keep the command strings as type StringBuilder for all of the event handler methods if you wish to be consistent, and change UpdateDB's cmdString argument to be of type StringBuilder, however, you then must convert the string argument to be of type string inside the UpdateDB method in order to feed it to SqlCommand:

SqlCommand command = new SqlCommand(cmdString.ToString(), connection);

which means you would also have to update the Delete button's click event handler method's deleteCommand variable to be of type StringBuilder as well when passing it onto the UpdateDB method, otherwise you'll get build errors.

Note from the Author or Editor:
Change the btnAdd_Click, btnEdit_Click and btnDelete_Click functions on page 505 to the following

protected void btnAdd_Click(object sender, EventArgs e)
{
String insertCommand = String.Format("insert into SalesLT.ProductCategory ([ParentProductCategoryID], [Name]) values ('{0}', '{1}')",
ddlParentCategory.SelectedValue, txtName.Text);
UpdateDB(insertCommand);
PopulateGrid();
}

protected void btnEdit_Click(object sender, EventArgs e)
{
String updateCommand = String.Format("Update SalesLT.ProductCategory SET Name='{0}', ParentProductCategoryID='{1}' where ProductCategoryID='{2}'",
txtName.Text, ddlParentCategory.SelectedValue, hdnCategoryID.Value);
UpdateDB(updateCommand);
PopulateGrid();
}
protected void btnDelete_Click(object sender, EventArgs e)
{
string deleteCommand = String.Format("delete from SalesLT.ProductCategory where ProductCategoryID ='{0}'", hdnCategoryID.Value);
UpdateDB(deleteCommand);
PopulateGrid();
}

btnEdit_Click event handler method

When creating or appending to StringBuilder types on a new line, you cannot use {1} or {2}; they must start at {0} again:

updateCommand.AppendFormat("Name='{0}', ", txtName.Text);
updateCommand.AppendFormat("ParentProductCategoryID='{1}' ", ddlParentCategory.SelectedValue); // this line produces a zero-base FormatException error

however, when changing {1} to {0} due to a new call to updateCommand.AppendFormat(), the error goes away and the page behaves as expected.

Note from the Author or Editor:
Change the listing for btnEdit_Click on page 505 to...

protected void btnEdit_Click(object sender, EventArgs e)
{
String updateCommand = String.Format("Update SalesLT.ProductCategory SET Name='{0}', ParentProductCategoryID='{1}' where ProductCategoryID='{2}'",
