Methods
Assign(Base)
Copies the contents of another, similar object.
Declaration
public override void Assign(Base source)Parameters
| Type | Name | Description |
|---|---|---|
| Base | source | Source object to copy the contents from. |
Overrides
Remarks
Call Assign to copy the properties from another object of the same type. The standard form of a call to Assign is
destination.Assign(source);
which tells the destination object to copy the contents of the source object to itself. In this method, all child objects are ignored. If you want to copy child objects, use the AssignAll method.

Break(BreakableComponent)
Breaks the contents of the object.
Declaration
public override bool Break(BreakableComponent breakTo)Parameters
| Type | Name | Description |
|---|---|---|
| BreakableComponent | breakTo | Object to put the part of content to that does not fit in this object. These two objects must have the same type. |
Returns
| Type | Description |
|---|---|
| System.Boolean | true if there is enough space in this object to display at least one text line. |
Overrides
Remarks
Do not call this method directly, it is used by the report engine. You should override it if you are writing a new FastReport object.
This method must break the contents of the object. The part of content that fit in current object's bounds should remain in this object, the part that does not fit should be transferred to breakTo object.
CalcHeight()
Calculates the object's height.
Declaration
public override float CalcHeight()Returns
| Type | Description |
