RadPanelBar Occupy 100% of Browser Window Height
- Add the following style in the head tag of your ASPX:
<style type="text/css">
html, body, form
{
margin:0px;
padding:0px;
height:100%;
}
</style>
Set the ExpandMode property of the panelbar control to FullExpandedItem;
Set Height="100%" in the definition of the panelbar control
Here’s a sample code snippet that demonstrates the approach:
<html xmlns="https://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Untitled Page</title>
<style type="text/css">
html, body, form
{
margin:0px;
padding:0px;
height:100%;
}
</style>
</head>
<body>
<form runat="server" id="mainForm" method="post">
<telerik:RadScriptManager ID="ScriptManager" runat="server" />
<telerik:RadPanelBar RenderMode="Lightweight" ID="RadPanelBar1" runat="server" Skin="Outlook" Height="100%" ExpandMode="FullExpandedItem">
