Errata

The versions of C# and VB indicated in the figure are incorrect. They show respectively v2.0 and v8.0 when the correspounding paragraphs clearly state C# 3.0 and Visual Basic 9.0

Note from the Author or Editor:
Completely correct. Figure 1-3 should be altered so that C# v2.0 should read C# v3.0 and Visual Basic v8.0 should read Visual Basic v9.0

Code specifies "strHtml += [TextBoxName].Value...". It should read "strHtml += [TextBoxName].Text...". Change ".Value" for ".Text".

Note from the Author or Editor:
As noted above, please change

"strHtml += [TextBoxName].Value..."

to read

"strHtml += [TextBoxName].Text..."

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

The line in error is :
..., there is only a single BulletedList control and the ID is known to us: bltList.

It should be changed to :
..., there is only a single BulletedList control and the ID is known to us: bltBooks.

Note from the Author or Editor:
As stated in the submitted errata, change bltList to bltBooks on line 18.

2nd para. is: Now drag a DropPanelExtender from the Toolbox...

2nd para. should be: Now drag a DragPanelExtender from the Toolbox...

DropPanelExtender sounds like a cross between DropShadowExtender and DragPanelExtender (the 2 controls being discussed in the section). At least I couldn't find any such name in the toolbox, and then this isn't errata.

Note from the Author or Editor:
In para 2 on page 209, change 'DropPanelExtender' to read 'DragPanelExtender'

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");

You say recall that the WeekendDayStyle is set to the colour LavenderBlush, it isn't, that was in the Calendar-Styles.aspx exercise.

Note from the Author or Editor:
p292 - Replace the second sentence with the following. "Recall that in a previous exercise we showed how to set styles on a calendar control, including setting the WeekendDayStyle to LavenderBlush."

You already have a confirmed errata for page 331 where you have indicated that the 2nd element of the Books array should be "Fiction". If that is the case, then this figure should show the word Fiction not Novels.

Note from the Author or Editor:
Figure 6-10 should be retaken to reflect that Novels has been replaced by Fiction

In the code for the CS file, you assign a string to lblInfo.Text, but there is no such control in DetailsView.aspx, so far in this example. You need to ask the reader to add this control further up the page.

Note from the Author or Editor:
p404. change the top sentence and code block as follows.

To demonstrate, open DetailsView.aspx and set the DataKeyNames property as highlighted here. You'll also need to add a Label control to display the Customer details on the page:

<asp:DetailsView ID="CustomerDetails"
runat="server" DataSourceID="dsCustomers"
AllowPaging="True" EmptyDataText="No data was found"
DataKeyNames="CustomerID, RowGuid">
</asp:DetailsView>
<p>
<asp:Label runat="server" ID="lblInfo" />
</p>

The error is EmptyDataText'Description in the Table 8-11.
Error description is:
Sets the text displayed by the DetailsView if the DataSource it is bound to returns no data to display

It should be changed to:
Sets the text displayed by the GridView if the DataSource it is bound to returns no data to display.

Note from the Author or Editor:
As noted above, the word DetailsView should be changed to the word GridView in the Description of the EmptyDataText property

The error is EmptyDataText'Description in the Table 8-11.
Error is:
Sets the CSS class name for the table generated by the DetailsView control.

It should be changed to:
Sets the CSS class name for the table generated by the GridView control.

Note from the Author or Editor:
The description of the CssClass property on p424 should start with "Sets the CSS class name for the table generated by the GridView control."

The error is:
Extends the BoundField to render (a combination of) fields as hyperlinks in the DetailsView.

It should be changed to:
Extends the BoundField to render (a combination of) fields as hyperlinks in the GridView.

Note from the Author or Editor:
Please make change as noted in the errata above

The error is:
change their command types depending on the current mode of the DetailsView.

It should be changed to:
change their command types depending on the current mode of the GridView.

Note from the Author or Editor:
Please make change as noted in errata above.

The error is :
Example 8-11. Repeater.aspx.cs in full

It should be changed to :
Example 8-11. Repeater.aspx in full

Note from the Author or Editor:
Please make change as noted in errata above.

The error is :
ItemTemplate will be used for every item in the DataList.

It should be changed to :
ItemTemplate will be used for every item in the ListView.

Note from the Author or Editor:
Please make change as noted in errata above.

The error line is:
// between Bug and Order Details on the OrderID key

It should be changed to:
// between Order and Details on the OrderID key

Note from the Author or Editor:
As stated above, the second line of text on the page

// between Bug and Order Details on the OrderID key

should be changed to

// between Order and Details on the OrderID key

The line in error is :
When OrderGridView was added to DataRelations.aspx, its DataKeyValues property was set to OrderID.

It should be changed to :
When OrderGridView was added to DataRelations.aspx, its DataKeyNames property was set to SalesOrderID.

Note from the Author or Editor:
Please make change as noted in errata above.

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..."

The first line of PageLoad tries to load an XML document using:

XElement.Load(Request.ApplicationPath+"\\authors.xml");

this yields a wrong path, code should read:

XElement.Load(Request.MapPath("~/authors.xml"));

which will map the file path correctly to the filesystem.

Note from the Author or Editor:
On page 553, the first highlighted line of code should be changed to read

XElement doc = XElement.Load(Request.ApplicationPath+"\\authors.xml");

ID for the text box control should be "txtPageNumber", not "txtNumPurch"

Note from the Author or Editor:
The code at the bottom of page 590, line 4, should read

<asp:TextBox ID="txtPageNumber" runat="server" />

The line in error is :
..., and the Text property of that SiteMapNode returns that SiteMapNode's title.

It should be changed to :
..., and the Title property of that SiteMapNode returns that SiteMapNode's title.

Note from the Author or Editor:
In the 2nd paragraph, replace "and the Text property of that SiteMapNode returns that SiteMapNode's title." with "and the Title property of that SiteMapNode returns that SiteMapNode's title."

The line in error is :
Example 14-12 DisplayMode.aspx in full

It should be changed to :
Example 14-12 DisplayModeMenu.ascx in full

Note from the Author or Editor:
Change the caption for the code sample at the bottom of page 738 to Example 14-12 DisplayModeMenu.ascx in full
Change the caption for the code sample at the bottom of page 739 to Example 14-13 DisplayModeMenu.ascx.cs in full

public int NumOfColumns
{
get { return numOfColumns; }
set { numOfColumns = value; }
}
public RepeatDirection direction
{
get { return direction; }
set { direction = value; }
}

when you declare the above 2 public properties, the second one "direction" is written exactly as the next instruction where you initialize the private members.

private int numOfColumns = 3;
private RepeatDirection direction = RepeatDirection. Horizontal;

So, the compiler shows an error, because that variable "direction" is delcared two times.

the Solution is to declare the property with this name "Direcion" and that is it.

Regards...

Note from the Author or Editor:
On Page 755, capitalise the name of the public property from 'direction' to 'Direction'
