循环repeater中的个数并且访问repeater中的控件

protected void button_Click(object sender, EventArgs e)

        {

            for (int i = 0; i <repeater.Items.Count; i++)

            {

                CheckBox chksel = (CheckBox)DataList1.Items[i].FindControl("selected");

                if (chksel != null)

                {

                    if (chksel.Checked)

                    {

                      

                        string users = ((Label)DataList1.Items[i].FindControl("users")).Text;

                        string dept = ((Label)DataList1.Items[i].FindControl("dept")).Text;

                        string post = ((Label)DataList1.Items[i].FindControl("post")).Text;

 sql.ExecuteDataset("insert into addnightsalary (users,dept,post,salary,date,days,salarys,mark)values('"+users+"','"+dept+"','"+post+"','"+TextBox3.Text+"','"+TextBox6.Text+"','"+TextBox4.Text+"','"+TextBox5.Text+"','"+TextBox7.Text+"')", "a");

                    }

                }

 

            }
