By default, the control's ForeColor property indicates the FilterFor field. Use the FilterForVisible property to display a text box editor in the bottom side of the drop down portion of the control to allow filtering items in a different way. The FilterForBackColor property specifies the backcolor for the FilterFor field. The height of the FilterFor field is determined by the control's FilterBarFont property. The control fires the EditChange(-1) event when the user alter the text in the FilterFor field. The -1 parameter indicates the FilterFor field. Use the EditText(-1) property to specify the text being displayed in the FilterFor field.
