Solution 1

you can get comma separated value as below in textbox..

C#

CON.Open();
SqlCommand CMD = new SqlCommand("SELECT CUST_NAME FROM CUSTOMER WHERE CUST_ID=CUST_NAME", CON);
SqlDataReader DR = CMD.ExecuteReader();
while (DR.Read())
{
    CUST_NAME.Text += DR["CUST_NAME"].ToString();
}
CON.Close();

Solution 2

Well, it won't work, unless your customer id is "CUST_NAME".
Try this:

C#

CON.Open();
SqlCommand CMD = new SqlCommand("SELECT CUST_NAME FROM CUSTOMER WHERE CUST_ID=@ID", CON);
CMD.Parameters.AddWithValue("@ID", myCustomerIDThatIAmLookingFor);
SqlDataReader DR = CMD.ExecuteReader();
if (DR.Read())
   {
   CUST_NAME.Text = DR["CUST_NAME"].ToString();
   }
CON.Close();

Note that I also changed your while loop to an if - since you overwrite the text in the box each time a loop is probably not what you want...

MR.GRIFF ,
THIS IS RIGHT , BUT I AM TRYING ALL CUST_NAME IN TEXTBOX LIKE COMBOBOX
I WANT, WHEN I AM WRITE 1st CHARACTOR OF MY NAME THEN WHOLE NAME WILL BE DISPLAY

DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

ok sir,
so sorry,but i am trying cust_name in textbox like combobox

OriginalGriff 25-Jun-13 3:52am

Doing it in a textbox is a pain - it's possible, but you have to handle selection and so forth in the same way that a combobox does, and given that a text box is generally single line it's not easy for the user to work with. If you make it multiline, then at least he can see the options, but...a text box is not a good choice for this. I would probably either use a list and a textbox (so the user enters in a TB and the results appear in the list) or use a combobox with a databinding instead.

Is there a very good reason for using a textbox for this?

C#

//search Details

SqlDataAdapter retail = new SqlDataAdapter("SELECT retailPrice FROM AddItem WHERE itemCode='" + comboBox2.Text + "'", DB.connection());

//create DataTable
            DataTable DT3 = new DataTable();
//Fill DataTable
            retail.Fill(DT3);
//Search Details Decimal
            decimal cat2 = (decimal)DT3.Rows[0][0];
//Fill textBox
            textBoxretail.Text = Convert.ToString(cat2);
