Label Control

Definition and Usage

The Label control is used to display text on a page. The text is programmable.

Note: This control lets you apply styles to its content!

Properties

Property	Description
id	A unique id for the control
runat	Specifies that the control is a server control. Must be set to "server"
Text	The text to display in the label

Example 1

In the following example we declare one Label control, one TextBox control, and one Button control in an .aspx file. When the user clicks on the button, the submit subroutine is executed. The subroutine copies the content of the TextBox control to the Label control:

<script runat="server">
  Sub submit(Sender As Object, e As EventArgs) 
   label.Text=txt.Text
  End Sub
</script>

<html>
<body>
<form runat="server">
<asp:Label id="label" Text="I'm a Label Control!" runat="server"/>
<p>
Write some text in the text box:
<asp:TextBox id="txt" Width="200" runat="server" />
</p>
<asp:Button id="b1" Text="Copy text to Label" OnClick="submit"
runat="server"/>
</form>
</body>
</html>

Example 2

In the following example we declare one ImageButton control and one Label control in an .aspx file. When the user clicks on the image, the image_Click subroutine is executed. The subroutine sends the message "Coordinates: " and the x and y coordinates of the click to the Label control:

<script runat="server">
  Sub image_Click(sender As Object, e As ImageClickEventArgs) 
    mess.Text="Coordinates: (" & e.X & ", " & e.Y & ")"
  End Sub
</script>

<html>
<body>
<form runat="server">
<h3>Click on the image:</h3>
<asp:ImageButton id="image1" runat="server"
ImageUrl="..\images\smiley.gif"
OnClick="image_Click"/>
<br /><br />
<asp:Label id="mess" runat="server"/>
</form>
</body>
</html>
