Examples

The following example code demonstrates how to use this property to display a list of settings that were not successfully saved.

private void AttachSettingsSavedEventHandler()
{
    ((ClientSettingsProvider)Properties.Settings.Default.Providers
        ["System.Web.ClientServices.Providers.ClientSettingsProvider"])
        .SettingsSaved +=
        new EventHandler<SettingsSavedEventArgs>(Form1_SettingsSaved);
}

private void Form1_SettingsSaved(object sender,
    SettingsSavedEventArgs e)
{
    // If any settings were not saved, display a list of them.
    if (e.FailedSettingsList.Count > 0)
    {
        String failedSettings = String.Join(
            Environment.NewLine,
            e.FailedSettingsList.ToArray());

        String message = String.Format("{0}{1}{1}{2}",
            "The following setting(s) were not saved:",
            Environment.NewLine, failedSettings);

        MessageBox.Show(message, "Unable to save settings",
            MessageBoxButtons.OK, MessageBoxIcon.Warning);
    }
}
Private WithEvents settingsProvider As ClientSettingsProvider = My.Settings _
    .Providers("System.Web.ClientServices.Providers.ClientSettingsProvider")

Private Sub Form1_SettingsSaved(ByVal sender As Object, _
    ByVal e As SettingsSavedEventArgs) _
    Handles settingsProvider.SettingsSaved

    ' If any settings were not saved, display a list of them.
    If e.FailedSettingsList.Count > 0 Then

        Dim failedSettings As String = String.Join( _
            Environment.NewLine, e.FailedSettingsList.ToArray())

        Dim message As String = String.Format("{0}{1}{1}{2}", _
            "The following setting(s) were not saved:", _
            Environment.NewLine, failedSettings)

        MessageBox.Show(message, "Unable to save settings", _
            MessageBoxButtons.OK, MessageBoxIcon.Warning)

    End If

End Sub

Remarks

One reason that the provider might fail to save the settings is if the current user has been logged out. You can use the FailedSettingsList property to determine whether any settings were not successfully saved.
