Friends,
I need your help displaying "Paid" or "Unpaid" in GridView Column named "Fees" as HeaderText, depending upon the status value which is Integer Int datatype, which is 1 or 2 in sql server 2008 database table data,
using c# asp dot net 2010

Here is .aspx page

ASPX

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns = "false">
<Columns>
    <asp:BoundField DataField = "SID" HeaderText = "Student ID" />
    <asp:BoundField DataField = "FName" HeaderText = "First Name" />
    <asp:BoundField DataField = "Status" HeaderText = "Fees" />
 </Columns>
</asp:GridView>

How can I do it in c# that shows "Paid" for status 1 and "UnPaid" for status 2
kindly help
Thanks
Ravi

What I have tried:

C#

private void BindStudentGrid()
{
    SqlConnection constr = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["mytest1ConnectionString"].ToString());
    string query = "select * from Student";
    SqlConnection con = new SqlConnection(constr);
    SqlDataAdapter sda = new SqlDataAdapter(query, con);
    DataTable dt = new DataTable();
    sda.Fill(dt);

    GridView1.DataSource = dt;
    GridView1.DataBind();
}

As with your previous question, the simplest option is to change the query to return the correct values:

C#

private void BindStudentGrid()
{
    string connectionString = ConfigurationManager.ConnectionStrings["mytest1ConnectionString"].ConnectionString;
    
    const string query = "SELECT SID, FName, CASE Status WHEN 1 THEN 'Paid' WHEN 2 THEN 'Unpaid' ELSE '#Unknown#' END As Status FROM Student";
    
    using (SqlConnection con = new SqlConnection(connectionString))
    {
        SqlDataAdapter sda = new SqlDataAdapter(query, con);
        DataTable dt = new DataTable();
        sda.Fill(dt);
        
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
}
