Kindly tell me how I can access and change the settings programmatically. e.g. in the code below I want to access maxInvalidPasswordAttempts,  minRequiredPasswordLength etc. and update through a web form. Please help.

  <membership>
  <providers>
  <clear />
  <add name=”AspNetSqlMembershipProvider”
  type=”System.Web.Security.SqlMembershipProvider, System.Web,
  Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a”
  connectionStringName=”LocalSqlServer”
  enablePasswordRetrieval=”false”
  enablePasswordReset=”true”
  requiresQuestionAndAnswer=”false”
  applicationName=”/”

  Here's some sample code to get started. It's not for the exact section you wanted, but it will get you started on how to use the config API.

  protected void _button_Click(object sender, EventArgs e)
      {
          Configuration configFile =
              System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
  
          System.Web.Configuration.AuthenticationSection section =
              (System.Web.Configuration.AuthenticationSection)
                  configFile.GetSection("system.web/authentication");
          section.Mode = System.Web.Configuration.AuthenticationMode.None;
          
          configFile.Save();
      }

  Define "membership details". That is, what is it you want to update? If it's the configuration, then the method show by Brock works and allows updates. Brea in mind though, that changes to web.config will recycle the application, thus losing state.

  Hi,

  I have mentionad everything in my question. I want to update minRequiredPasswordLength, minRequiredNonalphanumericCharacters and such other details found in membership element in web.config file programmatically. So kindly tell me what is the way to update those details programmatically and safely.

  Many thanks

  Right. I wasn't sure whether you meant the physical web.config file, or the values as loaded at runtime. Try

              Configuration configFile = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
   
              System.Web.Configuration.MembershipSection section =
                  (System.Web.Configuration.MembershipSection)configFile.GetSection("system.web/membership");
              ProviderSettings settings = section.Providers["AspNetSqlMembershipProvider"];
   
              settings.Parameters["minRequiredPasswordLength"] = "3";
              settings.Parameters["minRequiredNonalphanumericCharacters"] = "3";
   
              configFile.Save();

              ProviderSettings settings = section.Providers["AspNetSqlMembershipProvider"];
   
              settings.Parameters["minRequiredPasswordLength"] = "3";
              settings.Parameters["minRequiredNonalphanumericCharacters"] = "3";
   
              configFile.Save();

  Hi I tried almost this code (not exact) and I fall down into errors today in noon. And then I had to restore the config file again.

  So I want to know is it the safest way to update web.config file or try something else.

  Thanks

  What errors are you getting? The code works fine for me.

  This is really the only way to update the config file.

  Hi,

  I do not remember the error, but I will not repeat that again

  I will try your code and update here

  is it ok to use this code

  settings.Parameters.Set("maxInvalidPasswordAttempts", "5");

  Thanks

  Hi, I used that same code you provided and I am not getting any error, but the config file is not being saved at all.

  aspx page.

  <table
  cellpadding="4" class="style1">
  <tr>
  <td class="style2">
  Enable Password Retrieval</td>
  <td class="style3">
  <asp:CheckBox ID="chkPassRet" runat="server"></asp:CheckBox>
  </td>
  <td>
  &nbsp;</td>
  </tr>
  <tr>
  <td class="style2">
  Enable Password Reset</td>
  <td class="style3">
  <asp:CheckBox ID="chkPassRes" runat="server"></asp:CheckBox>
  </td>
  <td>
  &nbsp;</td>
  </tr>

  <tr>
  <td class="style2">
  <asp:Button ID="btnSave" runat="server" Text="Save Changes"
  onclick="btnSave_Click" />
  </td>
  <td class="style3">
  &nbsp;</td>
  <td>
  &nbsp;</td>
  </tr>
  </table>

  Code behind:

  protected void btnSave_Click(object sender, EventArgs e)
  {
  
  config = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
  section = (MembershipSection)config.GetSection("system.web/membership");

  ProviderSettings providerSettings = section.Providers["AspNetSqlMembershipProvider"];
  providerSettings.Parameters["enablePasswordRetrieval"] = chkPassRet.Checked.ToString();
  providerSettings.Parameters["enablePasswordReset"] = chkPassRes.Checked.ToString();
  config.Save();

  }

  Kindly tell me, what is the reason...

  thnaks
