Thanks a Ton Kirtan. I got what i want. One more Question. My Windows form has Controls all over it. When i press a button at the bottom of the form the focus is shifting upwards and that particular click event is not fired. Again if i press second time then its working. Similarly if i click on a tree node on the form the focus is shifting either up or down on the form. To be more precise the tree node is getting selected but the scrollbars are moving up and down and because of this the focus is not on the tree control. How shud i rectify it. Thanks Sairam
