Short answer: yes — there are a few clean ways to put DB values into labels. As said, you can walk returned data and set labels; and demonstrate the DataSet approach. Below are alternatives and practical tips so the value ends up in a label safely and reliably.

For a single-value query, use ExecuteScalar (simpler and lighter than filling a DataSet):

using (var conn = new SqlConnection(connString))
using (var cmd = conn.CreateCommand())
{
    cmd.CommandText = "SELECT FullName FROM Users WHERE Id = @id";
    cmd.Parameters.AddWithValue("@id", id);
    conn.Open();
    var result = cmd.ExecuteScalar();
    myLabel.Text = result == null || result == DBNull.Value ? "(none)" : result.ToString();
}

If you already have a DataTable (from whatever source), bind the label so it updates automatically instead of manual assignment:

label1.DataBindings.Clear();
label1.DataBindings.Add("Text", myDataTable, "ColumnName");

Practical tips and troubleshooting: always use parameterized queries to avoid injection; wrap connections/commands in using so resources are disposed; check for DBNull.Value before calling ToString(); avoid blocking the UI thread — use async/await or run DB calls on a background thread and marshal updates back to the UI thread (Control.Invoke or check InvokeRequired). If a query returns nothing, log the SQL and parameters and test it in your DB console to confirm expected results. For ASP.NET WebForms the same assignment goes in Page_Load (guarded by !IsPostBack); for WPF use data binding to a view model instead.

For : start with ExecuteScalar for one field or a data-bound label for row/column display, and add null checks and proper disposal as shown above.

I don't know whitch kind of data base you use but any way. Fill a dataset object with data using Data Adapter as normally
then

you can get the cell value of a given data table as follow and set it to the textbox.text

textBox.Text = dataset.tables[0].rows[ row index here][cell index here];

Hi

SqlConnection ObjConn = new SqlConnection(ConnectionString);


if (ObjConn.State != ConnectionState.Open)
{
ObjConn.Open();
}


SqlDataAdapter ObjSqlDataAdapter = new SqlDataAdapter(CommandText, ObjConn);


Ds = new DataSet();
ObjSqlDataAdapter.Fill(Ds);


if (ObjDs.Tables[0].Rows.Count > 0)
{
label1.Text = ObjDs.Tables[0].Rows[rowindex][columnname].toString();
-
-
}


ObjDs.Dispose();
ObjConn.Close();
ObjConn.Dispose();
