Control::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:
virtual property CreateParams^ CreateParams {
	CreateParams^ get ();
}

Property Value

Type: System.Windows.Forms::CreateParams
A CreateParams that contains the required creation parameters when the handle to the control is created.

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 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.


virtual System::Windows::Forms::CreateParams^ get() override
{

   // Extend the CreateParams property of the Button class.
   System::Windows::Forms::CreateParams^ cp = __super::CreateParams;

   // Update the button Style.
   cp->Style |= 0x00000040; // BS_ICON value
   return cp;
}
