Technical overview

This sample includes the following two pages:
  • Default
  • Image
The Default page populates a FormView control by using data from a SQL Server database. The Default page provides a user interface (UI) for data manipulation.

In both the InsertItemTemplate template and the EditItemTemplate template, there is a FileUpload control for getting the specified image file when you perform an insert operation or an update operation. The following code uses a FileUpload control:
FileUpload uploadPicture = (FileUpload)fvPerson.FindControl("uploadPicture");if (uploadPicture.HasFile){    cmd.Parameters.Add("@Picture", SqlDbType.VarBinary).Value = uploadPicture.FileBytes;}else{    cmd.Parameters.Add("@Picture", SqlDbType.VarBinary).Value = DBNull.Value;}
In the InsertItemTemplate, EditItemTemplate, and ItemTemplate templates, the Image control links to the Image page to display images. The following code uses the Image control:
<asp:Image ID="imgPicture" runat="server" ImageUrl ='<%# Eval("PersonID","Image.aspx?PersonID={0}") %>' Width="128px" Height="128px" />
The Image page is used to retrieve an image from a SQL Server database and to display the image in a Web page.

The Image page retrieves the image data from the database based on the value in a query string. Then, the Image page writes the byte array to the HTTP output stream to display the image.

Note For more information about how to create the sample application, see the Readme.txt file that is included in the download package.
