Introduction
I have created search webpart in Custom coding here.In Tool pane you can change the property of the webpart whether google search or yahoo search or Bing search or you can click the checkbox to give your search url.I have done this by using custom properties and also i have used all the custom properties in this example like enum,string,bool.
