/** @property */ public String get_DefaultFocus () /** @property */ public void set_DefaultFocus (String value)
public function get DefaultFocus () : String public function set DefaultFocus (value : String)
Property ValueThe ID of the control on the form to display as the control with input focus when the HtmlForm is loaded. The default value is an empty string ("").
Use the DefaultFocus property to access the control on the form to display as the control with input focus when the HtmlForm control is loaded. Controls that can be selected are displayed with a visual cue indicating that they have the focus. For example, a TextBox control with focus is displayed with the insertion point positioned inside of it.
The control with focus can also be set using the Focus or SetFocus methods. These methods have precedence over the DefaultFocus property. If either of these methods are called to set the control with focus, the value of the DefaultFocus property is ignored.
The following code example demonstrates how to set the DefaultFocus property to display a specified control on a form as the control with input focus when the form loads. When Form1 renders, notice that the insertion point is positioned in TextBox1, indicating that TextBox1 is the control with focus.
