Query: “How to I activate the scrollbar at the bottom of the window so that I can scroll horizontally as well as vertically?”
From your query, we understand that you need to render the scrollbar at bottom (horizontal scrollbar) inside the ejGrid. We suggest you to achieve your requirement by defining the width and height property of scrollSettings.
Refer the below code example
ej:Grid ID="OrdersGrid" runat="server" AllowScrolling="True" AllowSorting="True">
<Columns>
…...............................................................
<ScrollSettings Height="300" Width="880" ></ScrollSettings>
Refer our UG documentation and online demo for your reference
Please get back to us if you have further queries.
