Question

How would i stop data repeating itself in a label?

at the moment my balance keep adding a value next to it for e.g balance: 500.000, 500.000

where i only want it to open once. here the code i am using

SqlDataReader readdata;

try
{

    sqlCommandbalance.Connection.Open();
    sqlCommandbalance.Parameters["@accountID"].Value = show.accountID;
    readdata = sqlCommandbalance.ExecuteReader();
    string balanceDB = null;
    string availableBalance = null;
    while (readdata.Read())
    {
        balanceDB = readdata["balance"].ToString();
        availableBalance = (Convert.ToDecimal(readdata["balance"].ToString()) + Convert.ToDecimal(readdata["overdraftlimit"])).ToString();
    }
    sqlCommandbalance.Connection.Close();
    balanceShow.Text += " " + balanceDB.ToString();
    availablebalanceShow.Text += " " + availableBalance.ToString();

Answer 1

you need to change this:

balanceShow.Text += " " + balanceDB.ToString();
availablebalanceShow.Text += " " + availableBalance.ToString();

to

balanceShow.Text = " " + balanceDB.ToString();
availablebalanceShow.Text = " " + availableBalance.ToString();

the += is equivalent to saying this:

balanceShow.Text = balanceShow.Text + " " + balanceDB.ToString();

which is why it is always appending the text to the existing text. You want to just assign the value of balance to the Text property.
