Introduction
The Image control lets you work with images from server code. Use the Image control to display any valid image supported by the requesting browser on the Web page. The path to the displayed image is specified by setting the ImageUrl property. You can specify the text to display in place of image when the image is not available by setting the AlternateText property. The alignment of the image in relation to other elements on the Web page is specified by setting ImageAlign property.
This control only displays an image. If you need to capture mouse clicks on the image, use the ImageButton control.
Example:
The following example demonstrates how to create an Image control on a Web page.
<%@ Page Language="C#" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>Image Example</title> <script language="C#" runat="server"> void Button_Click(Object sender, EventArgs e) { switch(DropList1.SelectedIndex) { case 0: Image1.ImageAlign = ImageAlign.NotSet; break; case 1: Image1.ImageAlign = ImageAlign.Left; break; case 2: Image1.ImageAlign = ImageAlign.Right; break; case 3: Image1.ImageAlign = ImageAlign.Baseline; break; case 4: Image1.ImageAlign = ImageAlign.Top; break; case 5: Image1.ImageAlign = ImageAlign.Middle; break; case 6: Image1.ImageAlign = ImageAlign.Bottom; break; case 7: Image1.ImageAlign = ImageAlign.AbsBottom; break; case 8: Image1.ImageAlign = ImageAlign.AbsMiddle; break; case 9: Image1.ImageAlign = ImageAlign.TextTop; break; default: Image1.ImageAlign = ImageAlign.NotSet; break; } } </script> </head> <body> <form id="form1" runat="server"> <h3>Image Example</h3> <div style="font-size:large"> Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text </div> <asp:Image id="Image1" runat="server" AlternateText="Image text" ImageAlign="left" ImageUrl="images/image1.jpg"/> <hr /> Select Image Align: <br /> <asp:DropDownList id="DropList1" runat="server"> <asp:ListItem>NotSet</asp:ListItem> <asp:ListItem>Left</asp:ListItem> <asp:ListItem>Right</asp:ListItem> <asp:ListItem>BaseLine</asp:ListItem> <asp:ListItem>Top</asp:ListItem> <asp:ListItem>Middle</asp:ListItem> <asp:ListItem>Bottom</asp:ListItem> <asp:ListItem>AbsBottom</asp:ListItem> <asp:ListItem>AbsMiddle</asp:ListItem> <asp:ListItem>TextTop</asp:ListItem> </asp:DropDownList> <br /><br /> <asp:Button id="Button1" Text="Apply Image Alignment" OnClick="Button_Click" runat="server"/> </form> </body> </html>
