Methods
AttachEvents()
Attaches Control events to its event handlers.
Declaration
protected override void AttachEvents()Overrides
Remarks
Override this method if your custom control has own events.
DetachEvents()
Detaches Control events from its event handlers.
Declaration
protected override void DetachEvents()Overrides
Remarks
Override this method if your custom control has own events. In this method, you should detach control's events that were attached in the AttachEvents() method.
GetSelectionPoints()
Gets the object's selection points.
Declaration
protected override SelectionPoint[] GetSelectionPoints()Returns
| Type | Description |
|---|---|
| SelectionPoint[] | Array of SelectionPoint objects. |
Overrides
Remarks
Selection point is a small square displayed at the object's sides when object is selected in the designer. You can drag this square by the mouse to change the object's size. For example, the TextObject has eight selection points to change its width and height by the mouse.
If you are developing a new component for FastReport, you may override this method if your object has non-standard set of selection points. For example, if an object has something like "AutoSize" property, it would be good to disable all selection points if that property is true, to disable resizing of the object by the mouse.
GetValue()
Returns value entered in the control.
Declaration
protected override object GetValue()Returns
| Type | Description |
|---|---|
| System.Object | The value of type supported by this control. |
Overrides
Remarks
This method must return a value entered by the user. For example, TextBox control must return its Text property value. If this control supports multi-selection, return selected values in an array, for example string[] array for CheckedListBox.
OnCheckedChanged(EventArgs)
This method fires the CheckedChanged event and the script code connected to the CheckedChangedEvent.
Declaration
public virtual void OnCheckedChanged(EventArgs e)Parameters
| Type | Name | Description |

Serializes the object.
Declaration
public override void Serialize(FRWriter writer)Parameters
| Type | Name | Description |
|---|---|---|
| FRWriter | writer | Writer object. |
Overrides
Remarks
Do not call this method directly. You should override it if you are developing a new component for FastReport.
This method is called when the object needs to save the state. It may happen when:
- saving the report to the file or stream;
- saving the report to the designer's undo buffer;
- assigning the object to another object using the Assign(Base) or AssignAll methods;
- saving the object to the designer's clipboard;
- saving the object to the preview (when run a report).
