PageControl Overview

Create a Page Control

Design Time

The ASPxPageControl control is available on the DX.24.1: Navigation & Layout toolbox tab in the Microsoft Visual Studio IDE.

PageControl in Toolbox

Drag the control onto a form and customize the control’s settings, or paste the control markup in the page’s source code.

Note

To properly function, DevExpress controls require that special modules, handlers and options are registered in the the Web.config file. Switch the Microsoft Visual Studio IDE to the Design tab to automatically update the Web.config file with the required DevExpress information.

Tab Scrolling

The page control allows you to scroll tabs in the tab header (ASPxPageControl.EnableTabScrolling).

ASPX

<dx:ASPxPageControl ID="ASPxPageControl1" runat="server" EnableTabScrolling="true" ...>
    <TabPages>
    ...
    </TabPages>
</dx:ASPxPageControl>

See demo

Templates

You can provide custom content for the page control. The following templates are available:

Customizable Appearance

The control’s appearance can be customized via specific style properties, or by assigning a CSS class.

ASPX

<dx:ASPxPageControl ID="ASPxPageControl1" runat="server" ...>
    <TabStyle Paddings-PaddingLeft="50px" Paddings-PaddingRight="50px"/>
    <ContentStyle>
        <Paddings PaddingLeft="20px"/>
    </ContentStyle>
    <TabPages>
    ...
    </TabPages>
</dx:ASPxPageControl>

Callbacks Support

The page control allows you to use the AJAX-based callback technology to perform round-trips to the server.

Use the page control’s ASPxTabControlBase.AutoPostBack property to control whether any end-user manipulation with the control’s elements (page tabs) requires a round trip to the server side for further processing.

Round trips to the server can be performed in the following ways:

standard postbacks (the whole page is refreshed)
the AJAX-based callback technology.

Use the ASPxPageControl.EnableCallBacks property to define how to perform round trips to server via the value.

See demo

Note

If you want to use a navigation control which only provides a tabbed interface but doesn’t contain any pages with child controls, consider using the ASPxTabControl control.
