'Declaration <DescriptionAttribute("Indicates if the dropdown can be shown.")> <CategoryAttribute("DropDown")> Public Property AllowDropDown As Boolean
'Usage Dim instance As WinTextBox Dim value As Boolean instance.AllowDropDown = value value = instance.AllowDropDown
[Description("Indicates if the dropdown can be shown.")] [Category("DropDown")] public bool AllowDropDown {get; set;}
Setting the AllowDropDown property to false does not imply that the DropDownControl is a null reference (Nothing in Visual Basic).
If the AllowDropDown property is set to false, the DropDownButton will be hidden and an exception will be thrown if an attempt is made to open the dropdown programatically using the DroppedDown property or the OpenDropDown method.
