    foreach(DataGridItem dataGridItem in MyDataGrid.Items){
    //Get name from cell[0]
    String Name = dataGridItem.Cells[0].Text;
    //Get text from textbox in cell[1]
    String Age = ((TextBox)dataGridItem.FindControl("AgeField")).Text;
    //Get Checked property of Checkbox control
    bool IsGraduate = ((CheckBox)dataGridItem.FindControl("IsGraduateField")).Checked;
    // get Values from Checkboxlist
    String Skills = "";
    foreach(ListItem item in ((CheckBoxList)dataGridItem.FindControl("CheckBoxList1")).Items){
    if (item.Selected){
    Skills += item.Value + ",";
    }

    Skills = Skills.TrimEnd(',');
    //Get RadioButtonList Selected text
    String Experience = ((RadioButtonList)dataGridItem.FindControl("RadioButtonList1")).SelectedItem.Text;
    //Get DropDownList Selected text
    String Degree = ((DropDownList)dataGridItem.FindControl("DropDownList1")).SelectedItem.Text;
