                runat="server" />
              </td>
            </tr>
            <tr>
              <td align="right">
            <SharePoint:WebAdministrationSelector
                id="WebSelector"
                OnContextChange="OnWebContextChange"
                runat="server" />

            </tr>
            <tr>
              <td align="right">
                <SharePoint:ListAdministrationSelector
                    id="ListSelector"
                    OnContextChange="OnListContextChange"
                    runat="server" />
              </td>
            </tr>
          </table>

The following example shows how to handle the events for the list administration control used on the Web page in the previous example.

Copy

        protected void OnSiteContextChange(object sender, EventArgs e)
        {
            SiteAdministrationSelector siteSelect =
                (SiteAdministrationSelector)sender;

            if (String.IsNullOrEmpty(siteSelect.CurrentId))
            {
                WebSelector.Enabled = false;
            }
            else
            {
                WebSelector.Enabled = true;
            }
        }

        protected void OnWebContextChange(object sender, EventArgs e)
        {
            WebAdministrationSelector webSelect =
                (WebAdministrationSelector)sender;

            if (String.IsNullOrEmpty(webSelect.CurrentId))
            {
                ListSelector.Enabled = false;
            }
            else
            {
                ListSelector.Enabled = true;
            }
        }

        protected void OnListContextChange(object sender, EventArgs e)
