title: How to find all controls in Gridview?
body: <p>I have a <code>gridview</code>  which contains controls like <code>checkbox dropdownlist textbox</code> etc.. These controls are in <code>TemplateField</code> and some are in <code>updatepanel</code> in gridview. There is a <code>EditTemplateField</code> which has some controls and a <code>button</code>. When grid is in edit mode, Now I have to find all controls in this EditTemplateField in <code>button click event</code>. I know that this can be done using foreach loop but don't know how?</p>
