title: Inserting 1 or 0 in Bit field in sqlDatabase based on Checkbox checked in GridView
body: <p>I have a gridview which has a Checkbox Template Field, I am using C# code and basically when the user checks all the Checkboxes in the datagrid view I want to add a 1 or 0 into an SQL database with a datatype field Bit based on the checkbox being checked or not. Here is my code so far;</p>
  
  <pre><code>protected void SaveRegisterButton_Click(object sender, EventArgs e)
  {
              SqlConnection connection;
              SqlCommand command;
              int numRowsAdded;
              int id;
              //Boolean AttendanceChecked;
      foreach (GridViewRow row in GridView2.Rows)
      {
          if (((CheckBox)row.FindControl("AttendanceCheckBox")).Checked)
          {
  
  
              try
              {
                  // Connecting to the database using the connection string in the web.config file
                  connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["RegisterConnectionString"].ConnectionString);
  
                  // Create an INSERT Sql statement
                  // To prevent an Sql injection attack, we add parameters with names starting with an @ symbol
                  command = new SqlCommand("INSERT INTO Attendance(Present, StudentID, LessonID) VALUES(@AttendanceChecked, @StudentID, @LessonID)",
  
  
                  // Replace the parameters with the actual values read from the form
                  //command.Parameters.AddWithValue("@AttendanceChecked", SqlDbType.Bit).Value = AttendanceChecked;
                  //command.Parameters.AddWithValue("@AttendanceChecked", CheckBox("Attend
                  //com.Parameters.Add("@Approved", SqlDbType.Bit).Value = status;
  </code></pre>
  
  <p>I am struggling to implement this part of my project and any help would be much appreciated! Thanks in advance...</p>
