Positioning the win forms controls at Runtime.

Question

Hi All, I have different froms like formA,formB,formC,formD.All are derived from formParent. Assume formParent has 20 common controls.Child forms(formA,formB,formC,formD) will be displayed at runtime.When i am displaying the child form i want filterout some common controls and add some specific controls. Challenging tasks for me is 1: positioning them properly/rich UI. 2:Tab indexing Is there any samples impleementing the above functionalities. Thanks pavithran
