HtmlTextArea Control

Definition and Usage

The HtmlTextArea control is used to control a <textarea> element. In HTML, the <textarea> element is used to create a text area.

Properties and Events

Property	Description
Cols	The number of columns of the text area
id	A unique id for the control
Name	The unique name for the text area
OnServerChange	The name of the function to be executed when the contents of the textarea is changed
Rows	The number of visible rows of the text area
runat	Specifies that the control is a server control. Must be set to "server"
Value	The content of the textarea

Example 1

In the following example we declare an HtmlTextarea control and an HtmlGeneric control in an .aspx file (remember to embed the controls inside an HtmlForm control). When the submit button is triggered, the submit subroutine is executed. The submit subroutine sends the message "You wrote: " and the text the user wrote in the text area to the span control:

<script runat="server">
  Sub submit(sender As Object, e As EventArgs)
    s1.InnerHtml = "<b>You wrote:</b> " & t1.Value
  End Sub
</script>

<html>
<body>
<form runat="server">
What do you think of ASP.NET?<br />
<textarea id="t1" cols="35" rows="6" runat="server" />
<input type="submit" value="Submit" OnServerClick="submit"
runat="server" />
<br />
<span id="s1" runat="server" />
</form>
</body>
</html>
