Responsive Layout
The following article demonstrates the basics of creating a Responsive Layout.
Responsive Layout
The concept behind responsive layout is to adapt your application to the capabilities of the client (the end user) device (browser). This is usually done with two very simple transformations: resizing the content placeholders or hiding them. For example, showing the entire content of your web-site may not be quite user-friendly, in cases when it is browsed via mobile device. In that case you may need to hide portions of the content.
With the RadPageLayout control, you could easily do so, by using the responsive attributes: HiddenXl, HiddenLg, HiddenMd, HiddenSm, and HiddenXs. These manage the visibility of respective content place holders when viewed under various devices. In other cases you may need to resize a certain container. Again, that's easy to do with RadPageLayout and responsive attributes: SpanXs, SpanSm, SpanMd, SpanLg or SpanXl. Those attributes, as the name suggests, control the Span of the columns under the various breakpoints. In other words once you have created your initial design, adding responsive capabilities is just a matter of configuration and setting a couple of properties.
In order to use the RadPageLayout responsive capabilities on a mobile device, you have to add the following meta tag to the
head
section of the page:<meta name="viewport" content="width=device-width, initial-scale=1.0" />
.
Example
The example below, demonstrates how you could hide the sidebars, when the resolution is small (sm) or extra small (xs). In addition, you could observe how the Spans of the columns are changed, when the viewport size is less then 768px (using SpanXs and SpanSm).You can find more information about viewport breakpoints in the this article.
<head id="Head1" runat="server">
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title></title>
<style type="text/css">
body {
margin: 0;
padding: 0;
padding-top: 20px;
font: 14px/normal "Segoe UI", sans-serif;
}
.col, .header, .footer {
background-color: #78a6ab;
border: 1px solid #cccccc;
text-align: center;
border-radius: 3px;
}
.header, .footer {
height: 50px;
}
.col {
margin: 10px 0;
padding: 5px 10px;
height: 100px;
}
</style>
</head>
<body>
<form id="form1" runat="server">

The Figures bellow, demonstrates the different layout, regarding the different resolutions.
