and these count value will show on the lable;
i write these code.....

SqlConnection con2 = new SqlConnection(ConfigurationManager.ConnectionStrings["sst"].ToString());
con2.Open();
SqlCommand c1 = new SqlCommand("Select COUNT(hosting) from mastertable where [user]='" + lblnam.Text + "'", con2);
SqlDataAdapter da1 = new SqlDataAdapter(c1.CommandText, con2);
DataSet ds1 = new DataSet();

da1.Fill(ds1);
lbhosttake.Text = ds1.Tables[0].Rows.Count.ToString();
con2.Close();

here lbhosttake is a lable that will show the count value.. Actually as i run it shows the count value only 1.
Weather the record is avaiable or not, weather has many record,, but it shows only 1 every time..

what can i do. so that it will show total counting value.

use SqlCommand.ExecuteScalar Method[^]

C#

con2.Open();
SqlCommand c1 = new SqlCommand("Select COUNT(hosting) from mastertable where [user]='" + lblnam.Text + "'", con2);
int count=(int)c1.Executescalar();
lbhosttake.Text =count.ToString();

Select COUNT(hosting) from .. return only single value ( one row), so the row count will be one. You need to read the value of the return row with Executescalar method or read the value of ds1.Tables[0].Rows[0].Cels[0] value
