How do I get the uploaded filename on the server after a successfull uplaoid

[David Farmer]

Hi, I'm using your asp.net Uploadbox control with the associated handler files for Save and delete file. The upload process is working correctly but I'm having difficulty retrieving the uploaded file(s) name on the server after upload. The UploadBox_Complete event is firing but I can't get the file names.

thanks

Got this working;

Private Sub UploadBox_Complete(sender As Object, e As Syncfusion.JavaScript.Web.UploadBoxCompleteEventArgs) Handles UploadBox.Complete

Dim strName As String

Dim data As Dictionary(Of String, Object) = e.FileStatus

For Each keyval As KeyValuePair(Of String, Object) In data

If keyval.Key = "name" Then

strName = keyval.Value.ToString

End If

Next

End Sub

Hi,  

In “.ashx” file I'm changing the original file name to randomly generated file name.  I want randomly generated saved file name and the path (path on server) in "UploadBox_Complete" event handler. Can you please help on this front ?

Hi KnjayGmail, 

Thank you for contacting Syncfusion forums. 

We can send the newly generated file name and its path as JSON object via the response text that is returned from the handler. Refer to the following code. 

public class saveFiles : IHttpHandler 

{ 

 

    public void ProcessRequest(HttpContext context) 

    { 

        List<uploadFile> Uploadfiles = new List<uploadFile>(); 

        string targetFolder = HttpContext.Current.Server.MapPath("uploadfiles"); 

        if (!Directory.Exists(targetFolder)) 

        { 

            Directory.CreateDirectory(targetFolder); 

        } 

        HttpRequest request = context.Request; 

        HttpFileCollection uploadedFiles = context.Request.Files; 

        if (uploadedFiles != null && uploadedFiles.Count > 0) 

        { 

            for (int i = 0; i < uploadedFiles.Count; i++) 

            { 

                string fileName = uploadedFiles[i].FileName; 

                Uploadfiles.Add(new uploadFile { oldname = fileName, newname = "Randomly Generated Name here", path = targetFolder }); 

                int indx = fileName.LastIndexOf("\\"); 

                if (indx > -1) 

                { 

                    fileName = fileName.Substring(indx + 1); 

                } 

                uploadedFiles[i].SaveAs(targetFolder + "\\" + fileName); 

 

            } 

        } 

        else 

        { 

 

        } 

        var json = JsonConvert.SerializeObject(Uploadfiles); 

        context.Response.ContentType = "text/json"; 

        context.Response.Write(json); 

    } 

 

    public bool IsReusable 

    { 

        get 

        { 

            return false; 

        } 

    } 

} 

 

public class uploadFile 

{ 

 

    public string oldname { get; set; } 

 

    public string newname { get; set; } 

 

    public string path { get; set; } 

 

} 

We can access the response text in the Uploadbox’s success event. Kindly refer to the following code. 

<ej:UploadBox ID="Upload1" SaveUrl="saveFiles.ashx" RemoveUrl="removeFiles.ashx" runat="server" ClientSideOnSuccess="fileuploadSuccess" ></ej:UploadBox> 

 

<script> 

    function fileuploadSuccess(e) { 

        var FileData = JSON.parse(e.responseText)[0]; 

        alert("New Name: " + FileData.newname); 

        alert("Path: " + FileData.path); 

    } 

</script> 

We have prepared a sample as per your requirement, please find the sample from the following location:  http://www.syncfusion.com/downloads/support/forum/119710/ze/UBmodifiedName-1902696265
