Constraining the Position
The Window provides the Draggable(d => d.Containment()) configuration option that you can use to constrain the movement of the widget inside a container element.
The Containment() option overrides the appendTo setting and attaches the Window to the specified DOM element. You have to correctly position the containment element by using the relative, absolute, or fixed CSS rules.
The following example demonstrates how to create a modal Window and constrain its movement inside a DOM element.
<style>
#container {
position: relative;
width: 500px;
height: 500px;
border: 1px solid grey;
}
</style>
<div id="container">
@(Html.Kendo().Window()
.Name("window")
.Title("Alvar Aalto")
.Width(300)
.Height(250)
.Draggable(d => d.Containment("#container"))
.Content(@<text>
<p>
Alvar Aalto is one of the greatest names in modern architecture and design.
Glassblowers at the iittala factory still meticulously handcraft the legendary vases
that are variations on one theme, fluid organic shapes that let the end user decide the use.
