Hi,
I have to add unlimited controls to the web form on run time.I have button called 'Add more controls'. When I click this button the code should generate one control(textbox, or Dropdownlist) to the form.If I click this button again it should add one more control to the page etc.How I can achieve this functionality?

Thanks..

OnClick event of the Button 'Add More Controls' ,add logic to generate control.If you have to add either textbox or dropdownlist then it is fine.You cant find out which controls(TextBox or DropDownList) to be added by click of single button.
