Property Value

Type: System.Deployment.Application.DeploymentProgressState
A DeploymentProgressState value, stating what element or elements the operation is currently downloading.

The following code example downloads a file group named HelpFiles, and displays download progress in a status bar. This example requires that you deploy a Windows Forms application, and that your main form has a StatusStrip control, and a ToolStripStatusLabel control named downloadStatus.


private void DownloadFileGroupAsync(string fileGroup)
{
    if (ApplicationDeployment.IsNetworkDeployed)
    {
        ApplicationDeployment deployment = ApplicationDeployment.CurrentDeployment;

        try
        {
            if (!deployment.IsFileGroupDownloaded(fileGroup))
            {
                deployment.DownloadFileGroupProgressChanged += new DeploymentProgressChangedEventHandler(deployment_DownloadFileGroupProgressChanged);
                deployment.DownloadFileGroupCompleted += new DownloadFileGroupCompletedEventHandler(deployment_DownloadFileGroupCompleted);

                deployment.DownloadFileGroupAsync(fileGroup);
            }
        }
        catch (InvalidOperationException ioe)
        {
            MessageBox.Show("This application is not a ClickOnce application. Error: " + ioe.Message);
            return;
        }
    }
}

void deployment_DownloadFileGroupProgressChanged(object sender, DeploymentProgressChangedEventArgs e)
{
    downloadStatus.Text = String.Format("Downloading file group {0}; {1:D}K of {2:D}K completed.", e.Group, e.BytesCompleted / 1024, e.BytesTotal / 1024);               
}

void deployment_DownloadFileGroupCompleted(object sender, DownloadFileGroupCompletedEventArgs e)
{
    if (e.Error != null)
    {
        downloadStatus.Text = "Could not download files. Will try again later.";
        return;
    }
    else if (e.Cancelled)
    {
        downloadStatus.Text = "The file download has been cancelled.";
        return;
    }

    downloadStatus.Text = String.Format("Download of file group {0} complete.", e.Group);
}
