    <p>I have the following code :</p> <pre><code>Connection c = new Connection(); string select1 = @"SELECT E.employeeNumber AS 'Employee Number', E.employeePrivateName + ' ' + E.employeeFamilyName AS 'Employee Name', DATEDIFF (MONTH, E.startWorkingDate, GETDATE()) AS 'Seniority in Month', M.machineName AS 'Machine Name', J.jobName AS 'Job Name', COUNT(E.employeeNumber) AS 'Number of Times on Machine in Specif Job', SUM(Number_Of_Days_During_The_Period) AS 'Total Working Days on Machine in Specif Job', SUM(Salary_per_Period) AS 'The Salary For working on Machine in Specif Job' FROM TblEmployee E INNER JOIN AllSchedules A_S on E.employeeNumber = A_S.employeeNumber INNER JOIN TblJob J on J.jobNumber = A_S.jobNumber INNER JOIN TblMachine M on M.machineNumber = A_S.machineNumber INNER JOIN TblPeriod P on P.Number = A_S.periodNumber WHERE Month(P.fromDate) = Month(@Month) GROUP BY E.employeeNumber, E.employeePrivateName, E.employeeFamilyName, E.startWorkingDate, M.machineName, J.jobName ORDER BY E.employeeFamilyName , E.employeePrivateName"; SqlCommand cmd = new SqlCommand(select1, c.con); DateTime month = comboBox1.Text; cmd.Connection = c.con; cmd.Parameters.AddWithValue("@Month", month); SqlDataAdapter dataAdapter = new SqlDataAdapter(cmd); //c.con is the connection string SqlCommandBuilder commandBuilder = new SqlCommandBuilder(dataAdapter); DataSet ds = new DataSet(); dataAdapter.Fill(ds); dataGridView1.ReadOnly = true; dataGridView1.DataSource = ds.Tables[0]; </code></pre> <p>I want to run the query, however I need to define a datetime value so it would be a search parameter for the query. How do I save the DateTime variable so that it will hold a month number (10 for october, etc.)</p> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
