c# control names

Is there a way to control how .Net sets the Name and ID property of my controls? I have some radio buttons for which I need the name to be the same. However if I set the ID property of the radio button control it sets the Name and the ID. I see no way to treat the ID and Name separately. So now all button’s ids are the same as well.

Clear textbox history in ASP.NET

how can I clear the history of a textbox? I have set autocomplet=off and set AutoCompleteType to Disabled. The history / text appears when I double click the textbox in Chrome / Firefox, so when I click it the text will be inserted in the textbox. Is there a way to stop this behaviour via ASP.NET / HTML?
