DropDownButtonPartClass Class

An instance of the DropDownButtonPartClass class represents a dropdown button part.

Cells can contain one or several dropdown buttons (instances of the DropDownButtonPartClass). Each dropdown button can operate independently with its own attributes and properties.

The Action event can be used to handle a dropdown button click.

If the Action event is used, the ItemClick event is not raised.

PublicEnabledDefines whether the dropdown button is enabled.
PublicInherited from Softelvdm.Controls.GenericPartClassHAlignDefines the horizontal alignment within the part's available space.
PublicInherited from Softelvdm.Controls.GenericPartClassOrientationReturns the orientation of parts within a cell. This is defined by the cell or the owner of the cell.
PublicInherited from Softelvdm.Controls.GenericPartClassPartAlignmentDefines the part alignment of this part relative to its container and other parts.
PublicInherited from Softelvdm.Controls.GenericPartClassPartOwnerReturns the owner of the part, usually an object derived from CellBaseClass.
PublicPressedDefines whether the dropdown button is currently pressed.
PublicInherited from Softelvdm.Controls.GenericPartClassTagObjectDefines application-specific data.
PublicInherited from Softelvdm.Controls.GenericPartClassTagStringDefines an application-specific string.
PublicInherited from Softelvdm.Controls.GenericPartClassVAlignDefines the vertical alignment within the part's available space.
PublicInherited from Softelvdm.Controls.GenericPartClassVisibleAppearanceReturns the visibility status of the part.

Methods

ProtectedInherited from Softelvdm.Controls.GenericPartClassCalcRotatedSizeCalculates the size of the smallest rectangle that can contain the rotated rectangle of a given size, based on the part's GenericPartClass.Angle property.
ProtectedCalcSizeCalculates the size of the part.
ProtectedInherited from Softelvdm.Controls.GenericPartClassCalcUnrotatedBaseWidthCalculates the actual width of the part, based on the width of the rotated part's containing rectangle.
ProtectedConsiderForOutlineDefines whether the part is considered when calculating the outline rectangle of a cell.
ProtectedCopyCreates an identical copy of the part.
ProtectedStaticInherited from Softelvdm.Controls.GenericPartClassCopyPartCopies information from one part to another.
PublicInherited from System.ObjectEqualsDetermines whether the specified object is equal to the current object.
ProtectedInherited from System.ObjectFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
PublicInherited from System.ObjectGetHashCodeServes as the default hash function.
PublicInherited from System.ObjectGetTypeGets the Type of the current instance.
ProtectedInherited from Softelvdm.Controls.GenericPartClassGetVisibleReturns the current visibility status of a part, based on the part's GenericPartClass.VisibleAppearance property.
ProtectedInherited from System.ObjectMemberwiseCloneCreates a shallow copy of the current Object.
ProtectedInherited from Softelvdm.Controls.GenericPartClassOnContentChangedCalled when the contents of the part changed.
PublicStaticInherited from System.ObjectReferenceEqualsDetermines whether the specified Object instances are the same instance.
ProtectedStrategyRoutineUsed to perform various actions the part supports, like rendering the part, hit-testing, determining its position and responding to mouse button clicks.
PublicInherited from System.ObjectToStringReturns a string that represents the current object.

Events

PublicInherited from Softelvdm.Controls.GenericPartClassActionOccurs when a part's action is triggered by the user.

Examples

C#

                        true, false, GadgetAppearanceEnum.ThemedSystem, null, "Click Me", null, Color.Red);
            bp.Action += new GenericPartClass.ActionEventHandler(bp_Action);
            item.Cells[1].Parts.Add(bp);

            // Add text to the third cell
            cell = item.Cells[2];
            cell.Text = "Sample Text";
            // Add a dropdown button (still in the third cell)
            DropDownButtonPartClass ddp = new DropDownButtonPartClass();
            ddp.Action += new GenericPartClass.ActionEventHandler(ddp_Action);
            ddp.PartAlignment = PartAlignmentEnum.FlushEnd;
            cell.Parts.Add(ddp);

            // Add another item
            item = sftTree1.ItemCollection.Add();

VB.NET

            True, False, GadgetAppearanceEnum.ThemedSystem, Nothing, "Click Me", Nothing, Color.Red)
    AddHandler bp.Action, AddressOf bp_Action
    item.Cells(1).Parts.Add(bp)

    ' Add text to the third cell
    cell = item.Cells(2)
    cell.Text = "Sample Text"
    ' Add a dropdown button (still in the third cell)
    Dim ddp As DropDownButtonPartClass = New DropDownButtonPartClass()
    AddHandler ddp.Action, AddressOf ddp_Action
    ddp.PartAlignment = PartAlignmentEnum.FlushEnd
    cell.Parts.Add(ddp)

    ' Add another item
    item = sftTree1.ItemCollection.Add()
