Telerik RadGrid lets you to set the number of vertical columns across which the auto-generated edit form will span. In the example above the edit form spans across three columns.
Below are the attributes which specifies the number of columns in the edit form and in which column the edit field will reside:

<EditFormSettings ColumnNumber="3" CaptionFormatString="Edit details for employee with ID {0}" CaptionDataField="EmployeeID">

<rad:GridBoundColumn UniqueName="FirstName" EditFormColumnIndex="0" HeaderText="FirstName" DataField="FirstName"></rad:GridBoundColumn>
