Drop down list has separate properties for the text and the underlying value. Text box doesn't have this kind of feature. It only shows what is set to Text property. If you want, you can use Tag property to store desirend information concerning the text you have fetched from the database. Just set the value of the Tag.

Note that text box can't have multiple values so you just set the text and the tag so you don't bind teh object as you do with drop down list.

Hi,

you just put below code into your try...catch box

try
{
con.Opern();
SqlDataReader sqlRed = cmd.ExecuteReader();
while (sqlRed.Read())
{
       //replace your text box name with TextBox1
       TextBox1.Text = Convert.ToString(sqlRed["MonthlyPay"]);
}

......
