body: <p>I'm a very noob and this is my first post guys, so your help is needed
  trying to disable all of radio buttons controls in listview when I check a checkbox
  and it is working for one row only.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>protected void chkb_DG_NO_CheckedChanged(object sender, EventArgs e)
          {
  
  
                      foreach (ListViewItem item in ListView1.Items)
                      {
                          RadioButton RD1 = (RadioButton)ListView1.Items[0].FindControl("R1");
                          RadioButton RD2 = (RadioButton)ListView1.Items[0].FindControl("R2");
                          RadioButton RD3 = (RadioButton)ListView1.Items[0].FindControl("R3");
                          RadioButton RD4 = (RadioButton)ListView1.Items[0].FindControl("R4");
                          RadioButton LD1 = (RadioButton)ListView1.Items[0].FindControl("L1");
                          RadioButton LD2 = (RadioButton)ListView1.Items[0].FindControl("L2");
                          RadioButton LD3 = (RadioButton)ListView1.Items[0].FindControl("L3");
                          RadioButton LD4 = (RadioButton)ListView1.Items[0].FindControl("L4");
                          RD1.Enabled = false;
                          RD2.Enabled = false;
                          RD3.Enabled = false;
                          RD4.Enabled = false;
                          LD1.Enabled = false;
                          LD2.Enabled = false;
                          LD3.Enabled = false;
                          LD4.Enabled = false;
                      }
