Clearing TextBox in ASP.NET

Question

I have a webpage where there is a text box with some default value.

I need to clear a value from a text box. I have 2 options

1. textbox.text="";
2. textbox.text.remove(0,length);

Here I would like to know which one I should use. This affects page performance because there are a lot of text fields on the page.

thanks
