CheckedListBox.CreateParams Property

Gets the required creation parameters when the control handle is created.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

protected override CreateParams CreateParams { get; }
/** @property */
protected CreateParams get_CreateParams ()

protected override function get CreateParams () : CreateParams

The CreateParams property should not be overridden and used to adjust the properties of your derived control. Properties such as the CreateParams.Caption, CreateParams.Width, and CreateParams.Height should be set by the corresponding properties in your control such as Control.Text, Control.Width and Control.Height. The CreateParams should only be extended when you are wrapping a standard Windows control class or to set styles not provided by the Windows Forms namespace. For more information about creating control parameters, see the CreateWindow and CreateWindowEx functions and the CREATESTRUCT structure documentation in the Windows Platform SDK reference located in the MSDN Library at http://msdn.microsoft.com/library.

Notes to Inheritors When overriding the CreateParams property in a derived class, use the base class's CreateParams property to extend the base implementation. Otherwise, you must provide all the implementation.

The following code example extends the CreateParams property of a Button derived class. The CreateParams.Style property is changed, which causes the button to display an Icon rather than an Image. This example requires that you have a class that inherits from the Button class.

/** @property 
 */
protected CreateParams get_CreateParams()
{
    // Extend the CreateParams property of the Button class.
    CreateParams cp = super.get_CreateParams();

    // Update the button Style.
    cp.set_Style(cp.get_Style() | 0x40); // BS_ICON value
    return cp;
} //get_CreateParams
