Hi Guys,, I'm trying to make background color in repeater with the condition, data come from database and then bind to repeater. I'm use bootstrap class for the background color.

The condition is :

- If status_anggota "AKTIF" it will show background color green ("text-center bg bg-success") on repeater.

- If status_anggota "TIDAK AKTIF" it will show background color red "text-center bg bg-danger" on repeater.

how to do that ?. Anny help could be appriciate.

What I have tried:

This is the code bihind

//This code not working

protected void StatusAnggota()
    {
        string HtmlStringAktif = "text-center bg bg-success";
        string HtmlStringTidakAktif = "text-center bg bg-danger";
        using (SqlConnection con = new SqlConnection(koneksi))
        {
            using (SqlCommand sqlcmd = new SqlCommand())
            {
                con.Open();
                sqlcmd.Connection = con;
                sqlcmd.CommandType = CommandType.Text;
                sqlcmd.CommandText = "Select * From dbo.tbl_anggota";
                using (SqlDataReader rdr = sqlcmd.ExecuteReader())
                {
                    if (rdr.Read())
                    {
                        new LiteralControl(HtmlStringAktif = rdr["status_anggota"].ToString());
                        SqlDataAdapter adp = new SqlDataAdapter(sqlcmd);
                        DataTable dt = new DataTable();
                        con.Close();
                        adp.Fill(dt);
                        Repeater1.DataSource = dt;
                        Repeater1.DataBind();
                    }
                    else
                    {
                        new LiteralControl (HtmlStringTidakAktif = rdr["status_anggota"].ToString());
                        SqlDataAdapter adp = new SqlDataAdapter(sqlcmd);
                        DataTable dt = new DataTable();
                        con.Close();
                        adp.Fill(dt);
                        Repeater1.DataSource = dt;
                        Repeater1.DataBind();
                    }
                }
            }
            con.Close();
        }
    }

This is the repeater

<asp:Repeater ID="Repeater1" runat="server">
        <HeaderTemplate>
            <table style="width: 100%;" id="myTable" class="table table-hover table-responsive table-borderless">

new LiteralControl(HtmlStringAktif = rdr["status_anggota"].ToString());

Why are you creating a control instance only to throw it away?

You can set a local variable without creating a new control instance:

HtmlStringAktif = rdr["status_anggota"].ToString();

But since you never use that local variable anywhere, you might as well get rid of that line entirely.

You'll also find that having the same line in the else block will throw an exception, because there is no row to read the value from.
