Datasheet

<asp:BoundField DataField=”EntryText” />

</Columns>

<PagerStyle BackColor=”#284775” ForeColor=”White”

HorizontalAlign=”Center” />

<SelectedRowStyle BackColor=”#E2DED6” Font-Bold=”True”

ForeColor=”#333333” />

<HeaderStyle BackColor=”#5D7B9D” Font-Bold=”True” ForeColor=”White”

</asp:GridView>

In the GridView control’s markup, the DataSourceID attribute specifies the source of the data, which is

the

ObjectDataSource control. In addition, the markup specifies which columns to display by setting

AutoGenerateColumns to False. A final step is to create a list of columns:

<asp:BoundField DataField=”EntryDate” />

<asp:BoundField DataField=”EntryTitle” />

<asp:BoundField DataField=”EntryText” />

</Columns>

As well as enabling the display of data, the ObjectDataSource control can also update, insert, and

delete records from a database, as demonstrated shortly.

Creating, Editing, and Viewing a Diary Entry

The DayView.aspx page allows for diary editing. This page contains a simple form allowing you to enter

title and diary entry details. It also displays any existing diary entry.

All of the hard work is done by use of the

DiaryEntry class. Its Page_Load event creates a new

DiaryEntry class, passing its constructor the current user’s DiaryId and also the date the page

refers to:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

Handles Me.Load

mDiaryEntry = New DiaryEntry(CInt(Session(“DiaryId”)),

CDate(dayShownLabel.Text))

changeDayCalendar.SelectedDate = CDate(dayShownLabel.Text)

changeDayCalendar.VisibleDate = changeDayCalendar.SelectedDate

If Not IsPostBack Then

entryTextTextBox.Text = mDiaryEntry.EntryText

entryTitleTextBox.Text = mDiaryEntry.EntryTitle

End If

End Sub
