This works for me:

<asp:Button ID="btnReset" runat="server" Text="Reset" 
OnClientClick="this.form.reset();return false;" />

why you added return false at the end? – yigitt Jan 22 '17 at 18:00
in order to prevent the default action of clicking the button and only run this portion of code that he wrote – hamada147 Aug 28 '17 at 09:17
This should be accepted as the correct answer. – Studocwho Apr 05 '21 at 11:13

Depends on your definition of reset. A trivial way to do something like this could be a button with codebehind:

Response.Redirect(Request.Url.PathAndQuery, true);

Or a variation thereof.

I'm surprised this answer was not given already. It would be more useful with a bit more detail; Explain that an ASP.NET form is really just an HTML form, and so putting that control inside the `
` element will work just as usual.

Seems to me the most elegant solution suggested here. – Tillito Aug 14 '14 at 14:13

Using javascript you can do:

document.forms[0].reset();

or

theForm.reset();  // at least with ASP.NET 2.0

As in

<input type='button' id='resetButton' value='Reset' onclick='theForm.reset();return false;' //>

Some solutions are listed here:

Clear a form in ASP.Net

I was looking for the same solution in ASP.Net to clear my form on the click and I landed on this post. I looked at all the comments and replies. I decided to use the plain old input tag and created a HTML reset button .It worked like a charm, no postbacks, not javascripts. If there is any catch, I couldn't find it...

This should work:

function resetForm() 
{ 
   var inputs = document.getElementsByTagName('input'); 
   for(var i=0;i<inputs.length;i++) 
   { 
       if(input[i].type == 'text')
          input[i].value = "";
   }
}
