In some cases, the DataItem may be a collection that requires the column name to be included in parentheses. A DataTable is one such example. Each row of the DataTable is exposed as a DataRowView, which allows access to the columns by an index number or column name. To retrieve the value of the price column, the following data binding code is used.

Using the Eval Method
Control qr code iso/iec18004 size with visual c#
to include qr and qr data, size, image with c#.net barcode sdk
The DataBinder class offers a static method called Eval, which can simplify access to data. The Eval method uses reflection to perform a lookup of the DataItem s underlying type by looking at the type metadata that is stored in the underlying type s assembly. Once the metadata is retrieved, the Eval method determines how to connect to the given field. The end result is that Eval provides a consistent method of binding to the data. The following code shows the binding to the Key property of the HashTable and the binding of the price column to the DataTable.

The consistent behavior that DataBinder.Eval provides comes at a high performance cost.

The Eval method provides an overloaded method that allows a format string to be assigned. Tables 6.1, 6.2, and 6.3 contain lists of formatting characters that can be used in a format string. The price can be modified to provide currency formatting as shown in the following code.

Data Bound Controls
Get barcode with .net

This section covers several of the data bound controls in more detail. Some of these controls, such as the ListBox and DropDownList control, were covered in the previous chapter. This chapter covers these controls and other controls with a strong focus on data binding.

ListBox and DropDownList Control
Control upc code size on java
ucc - 12 size for java
The ListBox and DropDownList controls are similar. Both provide the following properties that can be set in the Visual Studio .NET designer or in code:
Control code 3 of 9 image for vb
use .net framework barcode 3 of 9 writer todraw 3 of 9 for visual basic
DataSource DataMember DataTextField

The following code can be used to bind a HashTable to the ListBox:

using visual studio .net toadd pdf417 in asp.net web,windows application
Private Sub Page_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Dim h As New Hashtable() h.Add( Glenn , 0) h.Add( Joe , 2) h.Add( Mary , 3) h.Add( Frank , 1) h.Add( Anne , 2) ListBox1.DataSource = h ListBox1.DataTextField = Key ListBox1.DataValueField = Value DataBind() End Sub

When the ListBox is rendered to the browser, the browser source looks like the following code:

using barcode printing for reportingservice class control to generate, create qr code jis x 0510 image in reportingservice class applications.
<select name= ListBox1 id= ListBox1 size= 5 <option value= 0 >Glenn</option> <option value= 2 >Anne</option> <option value= 2 >Joe</option> <option value= 3 >Mary</option> <option value= 1 >Frank</option> </select>
The ListBox rendered as an HTML ListBox, which is a simple select tag with option tags containing the value attribute and the inner HTML of the option containing the text to be displayed.
Repeater Control
The Repeater control is probably the simplest of the template controls. It s simple because the Repeater control does not provide any styles or layout options. Presentation is purely the developer s job. The Repeater control simply provides the calls to the appropriate templates. The Repeater provides the following properties, which can be set in the Visual Studio .NET designer or in code:
DataSource DataMember
6
In addition, the Repeater allows assignment of the following template types:
HeaderTemplate FooterTemplate ItemTemplate AlternatingItemTemplate Separator Template
The Repeater control is the only template control that allows HTML tags to span across templates. This means that a <table> tag can be placed into the header template, each table row <tr> tag with its table data <td> tags and end tags can be placed into the item template and alternating item template. The end of the table tag may be placed into the footer template. In the next series of Repeater examples the follow code will be assigned to the Page_Load method. Entries are placed into a HashTable and the HashTable has been assigned to Repeater1 s DataSource.
Private Sub Page_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Dim h As New Hashtable() h.Add( Glenn , 46) h.Add( Joe , 42) h.Add( Mary , 31) h.Add( Frank , 36) h.Add( Anne , 24) Repeater1.DataSource = h DataBind() End Sub
At a minimum, the item template must be supplied. The item template is assigned in the HTML. The following example implements the item template:
<asp:Repeater id=Repeater1 runat= server > <itemtemplate> User Name: <%# DataBinder.Eval(container.dataitem, Key ) %> has <%# DataBinder.Eval(container.dataitem, Value , {0:C} ) %><hr> </itemtemplate> </asp:Repeater>
Figure 6.1 shows the browser output. The username is the Key property of the HashTable, while the amount is the Value property of the HashTable. An HTML horizontal rule tag has been added to place each user on a different line. The Value has been formatted as currency with the {0:C} format string.
