hi sanjeeb.. at first a textbox accepts the no. of textboxes to display upon btnclick.(suppose txtbox id is txtmain.) then the reqd no of txtboxes are displayed.therafter the text in txtmain is changed. For eg:let initially text in txtmain be 5 and 5 textboxes are displayed after button click. then text in txtmain is changed to 10. Now the previous 5 txtboxes shud not be deleted instead 5 new txtboxes to be added.and also the text in prev 5 txtboxes shud not be changed. Help me to solve this!!!
