0	Greetings Abhi, Check whether you have cleared the corresponding label or any other labels. clear the label on server side when binding the grid or performing any operation. add watch the label and check it. Thanks Abhi_patil, if this helps please login to Mark As Answer. \| Alert Moderator

0	You will get the contents in server side as the State of the Label controls is being stored into the ViewState of the page. So this will not work. Instead what you can do is that you can have a hidden field and store the value of the label in the hidden variable. when you are trying to clear the label value, clear the value of hidden field as well and in the server side get the value of the hidden field using Request.Form["hiddenFieldName"].ToString(); Hope this helps.

0	Instead of using Label, Use Text Box. Make the Border Width=0. So it'll seems like Label. Now you can use the following to Clear it. document.getElementById('ctl00_ContentPlaceHolder1_lblGrpSum').value=''; Abhi_patil, if this helps please login to Mark As Answer. \| Alert Moderator
