Controls You Can Use on Web Forms   ASP.NET Data Controls   DataList Control

---

By default, the DataList displays a single column in which the contents are rendered in a top to bottom sequence.

The DataList, though, includes a RepeatColumns property that can be set to render the list items in any number of columns, and a RepeatDirection property that can be set to render the items in either vertical or horizontal order.

For instance, speciying three columns with repeat direction set to Horizontal renders a list of items shown below:

1	2	3
4	5	6
7	8

Vertical layout for the same items results in the following:

1	4	7
2	5	8
3	6

1. Include the RepeatColumns and RepeatDirection property within the opening tag of the DataList control.

   <asp:datalist id="myList" runat="server"
      repeatcolumns=3 repeatdirection="horizontal">

2. If you are setting the property in code, use the RepeatDirection enumeration, as shown below.

   myList.RepeatDirection = RepeatDirection.Horizontal;

NOTE: When not specified, RepeatDirection defaults to Vertical.
