HtmlTextArea.Rows Property

Gets or sets the height (in characters) of the HtmlTextArea control.

Namespace:  System.Web.UI.HtmlControls
Assembly:  System.Web (in System.Web.dll)

public int Rows { get; set; }
<asp:HtmlTextArea Rows="Int32" />

Property Value

Type: System.Int32
The height (in characters) of the HtmlTextArea control. The default value is -1, which indicates that this property is not set.

Use the Rows property to specify or determine the height (in characters) of the HtmlTextArea control. If you enter text that takes up more lines than the height specified, scroll bars are enabled.

To control the width of the control, set the Cols property.

The following code example demonstrates how to use the Rows property to control the height of the HtmlTextArea control.

    TextArea1.Rows = Convert.ToInt32(Select1.Value);
    Span1.InnerHtml = "You wrote: <br />" + TextArea1.Value;
