Introduction and Demonstration
Display controls simply render text or images to the browser. Here is list of
such controls.
| Control | Purpose |
| Image | Displays the image specified in the control's ImageUrl property. |
| Label | Displays the text specified in the control's Text property. |
| Panel | Groups a set of controls (like a Frame control in Windows). |
| Table | Displays a table of information. This control has two collections: TableRows, which contains the rows, and TableCells, which contains the columns in a row. |
| TableCell | Represents a cell in a row of a Table control. |
| TableRow | Represents a row inside a Table control. |
The syntax of these
web controls is as follows:
<asp:Label
ID="MyLabel" Text="This
is a Label Control" BorderStyle="solid"
BorderColor="Green"
runat="Server"
/>
<asp:Image
ID="MyImage" ImageUrl="aspnet.gif"
runat="Server"
/>
<asp:Panel
ID="MyPanel" BackColor="lightblue"
BorderColor="Green"
BorderWidth="1">
<asp:Label
ID="MyLabel2"
Text="Static Text within
the Panel" runat="Server"
/>
<br>
<asp:TextBox
ID="PanelTB"
Text="TextBox inside
Panel" runat="Server"
/>
</asp:Panel>
They can then be accessed programmatically with a code fragment like the
following:
MyLabel.Text = "New
Label"
MyImage.ImageUrl = "NewImage.gif"
MyPanel.BackImageUrl = "NewImage.gif"

<%@

%>

<title>Display

<script
runat="server">
Sub Page_Load( )
MyLabel.Text = "New Label"
MyImage.ImageUrl = "aspnetian.jpg"
End Sub
</script>
</head>
