Accepted answer
instead of adding controls in form try adding in panal and then you can clear the controls from panel easily by using panalname.Controls.Clear()

I change
this.Controls.Add(button);
if (i % 5 == 0)
{
left = 10;
top += button.Height + 2;
}
else
{
left += button.Width + 2;
}
with this
this.Controls.Remove(button);

Do one thing, in next button write same as above code and intead of this.Controls.Add(button); write this.Controls.Remove(button); After this you can write same code as above with different query to add again. Try this, I don't have laptop now to check may be it works,. If .Remove is not there try something near to that for removing buttons.

What do you wanted to clear, you wanted to clear textbox values then in button click event you can write txtboxname.Text="";
