Property Checked As Boolean

Dim instance As IPropertyManagerPageGroup
Dim value As Boolean
 
instance.Checked = value
 
value = instance.Checked

bool Checked {get; set;}

property bool Checked {
   bool get();
   void set (bool value);
}

Return Value

True if the check box is selected, false if not

A group box on PropertyManager page can be created with a check box in its title. Selecting the check box causes the group box to expand so that all of the controls on that group box can be seen by the end-user. Clearing the check box causes the group box to close, or compress, so that all of the controls on that group box are hidden.

When a group box is expanded, the states of the controls within the group are not changed.  For example, if all of the controls are disabled, they remain disabled when the group box is expanded. The owner of the PropertyManager page is responsible for setting the control states.

When the end-user selects or clears the check box of a group box, the IPropertyManagerPage2Handler5::OnGroupCheck method is called, so that your program can react to this event and do things such as enabling the appropriate controls.  However, if your program is using this property to set the check box, then this method is not called and your program should set the controls after setting this property.

This property does not control whether or not there is a check box on your group box. That is determined when the group box is added. See IPropertyManagerPage2::AddGroupBox or IPropertyManagerPage2::IAddGroupBox, specifically the Options argument.
