Design ListView and Other Templated Controls

Design ListView and Other Templated Controls

ListView and other templated controls in ASP.NET are used to display data in a tabular format, where each row represents an item in a collection of data. These controls provide a powerful way to customize the display of data, allowing you to define the layout and appearance of individual rows and columns.

Here are the general steps to design a ListView control:

Define the ListView control in the markup of your ASP.NET page. The ListView control has several templates that you can use to define the layout of the control, such as the ItemTemplate, AlternatingItemTemplate, and EmptyDataTemplate.

Bind the ListView control to a data source. You can bind the control to a variety of data sources, including arrays, collections, and databases. You can use the DataSource and DataBind properties to bind the control to a data source.

Define the layout of the individual rows and columns in the control. You can use the ItemTemplate to define the layout of each item in the ListView control. You can also use the LayoutTemplate to define the layout of the entire control, including any headers or footers.

Customize the appearance of the control using CSS. You can use CSS to style the individual elements of the control, such as the headers, footers, and items. You can also use CSS to apply different styles to different templates in the control.

Here’s an example of how to design a ListView control in ASP.NET:

<asp:ListView ID=”ListView1″ runat=”server” DataSourceID=”SqlDataSource1″>

    <ItemTemplate>

        <tr>

            <td><%# Eval(“FirstName”) %></td>

            <td><%# Eval(“LastName”) %></td>

            <td><%# Eval(“EmailAddress”) %></td>

        </tr>

    </ItemTemplate>

    <LayoutTemplate>

        <table>

            <thead>

                <tr>

                    <th>First Name</th>

                    <th>Last Name</th>

                    <th>Email Address</th>

                </tr>

            </thead>

            <tbody>

                <asp:PlaceHolder runat=”server” ID=”itemPlaceholder”></asp:PlaceHolder>

            </tbody>

        </table>

    </LayoutTemplate>

</asp:ListView>

In this example, the ListView control is bound to a SqlDataSource control using the DataSourceID attribute. The ItemTemplate is used to define the layout of each item in the control, which consists of three columns: FirstName, LastName, and EmailAddress. The LayoutTemplate is used to define the layout of the entire control, including the header row and the placeholder for the items.
