    Hai Himanshu,
    Do you have the windows app or web application.
    If you are using the Web Application, you should not the issue as each time, it will refresh the grid and should fill the grid correctly.
    The problem can come when you are binding the data in the Windows Application as once the GridView is binded already, it will not get binded again so before binding the grid View, first you need to make the DataSource as null for the GridView and then bind it based on the result of new data.
    By this way, you can get the desired results.
    Hope it will be helpful to you.

    Better to put a breakpoint and then check the code whether dataset contains data or not. If DataSet contain data and then also gridview won't show records then place your piece of code here, we will check it and let you know..

    Hi Himanshu
    Always set grid datasource to null before assign new datasource to it.
    also for Web Application . write Gridview.DataBind().

    You can bind records before assign null in Gridview after bind try this code both

    using (SqlConnection con = new SqlConnection(strCon))
    SqlDataAdapter sqladp = new SqlDataAdapter("Select * from tblProducts", con);

    if (dt != null)
    Grd1.DataSource = null;
    Grd1.DataSource = dt;

    Hope it will be helpful to you.
