Friends,
I need your help, please.
I want to Count 'public schools' in each State(which is a column name) across all 50 States in USA(currently having 50 to 100 rows in sql server table named "tbl_PublicSchoolUSA") and display in 50 TextBox for each State using C# asp Dot Net Sql Server 2008

SELECT States, COUNT(States) AS Total_Schools
FROM tbl_PublicSchoolUSA
GROUP BY States
HAVING (COUNT(States) >= 1)

After all these days of "hard work(?)" had led nowhere.
Please help.
Thanks,
Ravi

What I have tried:

I tried the above SQL statement in Sql server 2008 - It works well - but, how can I display each value in each TextBox in ASP.Net.

This is my C# code

private void DisplayInTextBox()
{
string constring = (@"Data Source=.\....bla...bla..bla");
using (SqlConnection con = new SqlConnection(constring))
{
using (SqlCommand cmd = new SqlCommand("SELECT States, COUNT(States) AS Total_Schools FROM tbl_PublicSchoolUSA GROUP BY States HAVING (COUNT(States) >= 1)", con))
{
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
con.Open();
using (SqlDataReader sdr = cmd.ExecuteReader())
{
sdr.Read();
TextBox1.Text = sdr["Total_Schools"].ToString();////Total schools in California
TextBox2.Text = sdr["Some Alias Name"].ToString(); ///Total schools in New York
TextBox3.Text = sdr["Some Alias Name"].ToString(); ///Total schools in Ohio
TextBox4.Text = sdr["Some Alias Name"].ToString(); ///Total schools in Illinois
...............
...........
.........
}
con.Close();
}
}
}

Solution 1

Don't. Use a DataGridView instead.

Use an SqlDataAdapter instead of the SqlDataReader to load the state and count into a DataTable, then set that as the DataSource for a DataGridView and it will organise it for you in a much more flexible way.

Yes OriginalGriff - Thanks for the clue.
I tried this code and works well,

protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection conn = new SqlConnection(@"Data Source=.\....bla....bla....bla...");
conn.Open();
SqlCommand cmd = new SqlCommand("SELECT States, COUNT(States) AS Total_Schools FROM tbl_PublicSchoolUSA GROUP BY States HAVING (COUNT(States) >= 1)",conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);

foreach (DataRow row in dt.Rows)
{
TextBox3.Text = dt.Rows[0][0].ToString();
TextBox4.Text = dt.Rows[1][0].ToString();
TextBox5.Text = dt.Rows[2][0].ToString();
TextBox6.Text = dt.Rows[3][0].ToString();
}
}

but I want the count value to be displayed in "dynamically generated TextBox"
for the States that has some rows and SHOULD NOT display the TextBox that DOESNT have any rows.
(i.e) I want to display values in the TextBox for California,New York,Ohio,Illinois only.(other states are still under data entry)
So if I get any records entered in "tbl_PublicSchoolUSA" in "States" Column for Florida,Idaho then the values for Florida,Idaho
should be displayed along with other 4 States and so and so forth...
How can I achieve this.
Please help.
Thanks
Ravi.
