<div class="dx-fieldset">
  <div class="dx-field">

    The widget height in pixels.
  • string
    A CSS measurement of the widget height (e.g., "55px", "80%", "auto" and "inherit").
  • function
    The function returning the widget height. For example, see the following code.

rtlEnabled

Specifies whether or not the current component supports a right-to-left representation.

To switch the entire application/site to a right-to-left representation, use the static DevExpress.rtlEnabled field.
