    Hi Sonal,

    As per my understand the post you want to check or uncheck checkbox based on database value, if that is your requirement then refer below sample code.

    Design your TemplateField like below

    <asp:Label ID="lblChkStatus" runat="server" Text='<%=DataBinder.Eval(Container.DataItem,"CheckStatus")%>' />
    <asp:CheckBox ID="chkSelection" runat="server"/>

    DataSet ds=//get data from database;

    and in gridview rowdatabound event check the value of each record whether that row is checked or not.

    protected void gv_OnRowDataBound(object sender,GridviewRowEventArgs e)
    if((e.Row.FindControl("lblChkStatus") as Label))
    (e.Row.FindControl("chkSelection") as CheckBox).Checked=true;
    (e.Row.FindControl("chkSelection") as CheckBox).Checked=false;

    Try something like above to achieve your goal.

    you can use jQuery to find checkboxes and check or uncheck as per db value

    do you want it in MVC ? if yes then you can check below link

    else in ASP.NET you can put checkbox in gridview and on 'dataRowDataBound' event you can use 'FindControl' for checkbox and check it

    Hai Sonal,
    It seems that when the check-box is getting checked from the database, due to its post-back it gets unchecked again.
    So you need to use some client side script to make the check-box checked so that post-back should not occur and your check-boxes should be checked as per the database values.
    Hope it will be helpful to you.
