Dear valued customers,

You might be looking at the best way to store the files between using FileSystem or Database as BLOB. In this article, you will find interesting differences between these two solutions.

However, we also introduce about UXFileUpload, which is is a feature-rich file upload control supporting Silverlight 3, Silverlight 4, and WPF. It includes all standard features you expected in a file upload control, plus a multitude of innovative features that unique to UXFileUpload such as multiple upload worker process, comprehensive MVVM and commanding support, smart file chunk algorithm, very large file upload support, file-level cancellation, drag-and-drop files from operating system, and more.

Problem with UXFileUpload

ISOLDEV — Wed, 10 Aug 2011 18:03:14 GMT

Hi,

My problem with this control is as follows I'm doing an validation in the event UploadStarted when the validation is not met I want to cancel the file upload, I used the method CancelUpload (); without achieving the goal.

Is there any way we can do what I need?

Annex xaml code and xaml.cs

XAML
<Intersoft:UXFileUpload Grid.Row="4" Height="Auto" Width="250"
                                   Name="uploadCatalogo" HorizontalAlignment="Stretch" VerticalAlignment="Bottom" Margin="12,12,12,12"
                                   ServiceUrl="http://localhost:16219/UXFileUploadHandler.ashx"
                                   TargetFolder="~/ClientBin/MyStorageFolder" OverwriteExistingFiles="True"
                                   TargetWebUrl="http://{host}/ClientBin/MyStorageFolder"
                                   MaxFileSize="204800000" Style="{StaticResource PhotoUploadStyle}"
                                   IsAutomaticUpload="True" CanSelectMultiple="False"
                                   ShowStatisticsOnCompleted="False" EnforceFileTypeValidation="True"
                                   FileTypeFilter="Portable Document Format (*.pdf)|*.pdf"
                                   UploadedFileUrl="{Binding preview, Mode=TwoWay, ValidatesOnDataErrors=True}"
                                   Visibility="Visible" FilesUploaded="uploadCatalogo_FilesUploaded"
                                   FilesUploading="uploadCatalogo_FilesUploading"
                                   FilesUploadFailed="uploadCatalogo_FilesUploadFailed"
                                   UploadCancelled="uploadCatalogo_UploadCancelled"
                                   UploadStarted="uploadCatalogo_UploadStarted" />

XAML.CS

private void uploadCatalogo_UploadStarted(object sender, Intersoft.Client.UI.Aqua.UXInput.UploadEventArgs e)
        {
            hastoUpload = true;
            string fileName = ((Intersoft.Client.UI.Aqua.UXInput.FileUploadInfo)uploadCatalogo.Items[0]).FileName;
            if (!IsAlphaNumeric(fileName))
            {
                ErrorCallOut.HorizontalOffset = -170;
                ErrorCallOut.VerticalOffset = 270;
                ErrorCallOut.Content = "No se permiten caracteres especiales como nombre de archivo.";
                ErrorCallOut.IsOpen = true;
                uploadCatalogo.CancelUpload();
            }
            else
            {
                isUploading = true;
            }
        }

public bool IsAlphaNumeric(String strToCheck)
        {
            Regex objAlphaNumericPattern = new Regex("[^a-zA-Z0-9' '_]");
            MatchCollection col = objAlphaNumericPattern.Matches(Path.GetFileNameWithoutExtension(strToCheck));
            if (col.Count > 0)
                return false;
            return true;
        }
