Controls You Can Use on Web Forms   ASP.NET Standard Controls   FileUpload Control

---

To use a FileUpload Web server control, you add it to a page and then add controls and static text to it.

1. Declare an <asp:FileUpload> element on the page. For syntax, see FileUpload Control Syntax.
2. Optionally set the following properties of the FileUpload control to specify how the fileupload interacts with its child controls.

Property	Description
HorizontalAlign	Specifies how the child controls are aligned within the fileupload ( left, right, center, or justified ).
Wrap	Specifies whether content that is too wide for the fileupload is wrapped to the next line or truncated at the fileupload’s edge.

3. Optionally set the FileUpload's style attributes to create a distinct appearance for the group of controls within the fileupload.

<asp:FileUpload id="myFileUpload" backcolor="wheat" width=300 
   borderstyle="ridge" borderwidth=1 runat="server">

The following example shows how you can dynamically add controls to a FileUpload control at run time.
