thx for the link

after i updated to latest version, i got an error in aggregate columns saying "The name 'Sum' does not exist in the current context"

We have checked your reported problem and we suspect that you have not updated the latest version ejs.interop.min.js and ej2.min.js (17.2.34 version) in your application. So please refer to the latest version files like below code.   

[_Host.cshtml] 

  

Please let me know if you have any questions.

after the update in js files, the problem still exists

Hi Erick,  

 

Query: “after the update in js files, the problem still exists” 

Based on your suggestion we have prepared a sample and we are able to reproduce the reported issue in our end too. This is because in our latest Nuget release (17.2.0.34) we have modified our event arguments and some of our properties as strongly typed. Hence the reported issue occurred. To overcome the reported issue kindly modify the Type of GridAggregateColumn as below  

For your convenience we have prepared a sample which can be downloaded from below  

Sample:  https://www.syncfusion.com/downloads/support/forum/145959/ze/WebApplication2186113036  

Please get back to us if you have any other queries.

is there any sample how to get the filename after uploaded? because we need to save the filename and it's part of registration process 

since the uploader 'directly post' when click the upload so i'm thinking to 'resend' the filename back to the page and save it as part of the registration

thx,

erick

Hi Erick, 

  

Yes, we can get the file name after the file uploaded to the server using our “Success” event as mentioned in the below code example. Here, we have deserialized the success event arguments using JSON convertor to get the file name. 

  

  

Please find the sample from the below link. 

Sample Link: https://www.syncfusion.com/downloads/support/forum/145959/ze/WebApplication12124157869  

  

Also, currently we are working on to provide the specific type for success event arguments and this support will be included in our patch release scheduled on mid of August 2019. We appreciate your patience until then. 

   

You can track the status of the issue from the below feedback link.

Your example can work and i can get the file name but it will break when i try to upload a bigger file (> 5kb), 

i already set the MinFileSize="1024" MaxFileSize="1000000" accordingly.

at first i thought the code was wrong then i realize it has size limitation which occur eventhough we already set the maxfilesize property

any insight?

thx,

erick

Hi Erick, 

  

Sorry for the inconvenience. 

  

In the provided code example, you set the MaxFileSize is 1 MB for the Uploader component. But, we can upload the file up to 1 MB at our end and the reported issue is not reproduced in the given sample. Please attached the below screenshot to demonstrate this.

Please check the attached sample from below. 

Sample Link: https://www.syncfusion.com/downloads/support/directtrac/general/ze/WebApplication1143550219  

 

  

Also, ASP.NET Blazor application allow us to upload the limited size of files only. If you want to upload the large number of files, EJ2 Blazor file upload have the feature of chunck upload which is used to upload large number of files and it will split the file based on the size (In bytes) provided in ChunkSize API and sent the multiple requests. 

  

Please refer the below code example. 

  

UG Link for Chunk Upload: https://ej2.syncfusion.com/aspnet-core-blazor/documentation/uploader/chunk-upload/?no-cache=1  

  

Still issue persists, please revert with issue reproducing sample and which kind of files are uploaded in the Uploader component that will help us to check and provide the exact solution at our end.

Thanks for the update.. Ur sampe seems to work but it does not work in mine

I'm using serverside blazor

I attached what i mean

Thx, 

Erick

thx,

erick

i'm able to solve the issue

the configuration something like this

the link come from this 

Hi Erick, 

  

Thanks for the update. 

  

We would like to inform you that, if you are using server-side Blazor application, there are certain limitations (32 KB) to upload the files to the server. So, we need to go to configure the MaximumReceiveMessageSize using SignalR as mentioned in your last update.  

  

Uploader is working fine since we have provided the sample using the client-side hosted application in our last update. As we stated earlier, if you want to upload the large size of files in our Blazor Uploader, we suggest you to use chunk upload as mentioned in the below UG documentation link.

We'll keep in mind about chunk upload

I follow this Post and try your code for this

@using Newtonsoft.Json; 

@using Newtonsoft.Json.Converters; 

 

 

<EjsUploader ID="UploadFiles" Success="@OnSuccess"> 

<div> 

@code{ 

    public string FileName; 

    public void OnSuccess(object args) 

    { 

        //Deserialized the success event args using Newton soft. 

        SuccessEventArgs eventArgs = JsonConvert.DeserializeObject(args.ToString()); 

        // Assign the file name in the variable 

        FileName = eventArgs.File.Name; 

        // To reflect the DOM content 

        this.StateHasChanged(); 

    } 

    //Success event args class. 

    public class SuccessEventArgs 

    { 

        public object E { get; set; } 

        public FileInfo File { get; set; } 

        public string StatusText { get; set; } 

        public string Name { get; set; } 

        public string Operation { get; set; } 

        public ResponseEventArgs Response { get; set; } 

    } 

 

    public class ResponseEventArgs 

    { 

        public string Headers { get; set; } 

        public object ReadyState { get; set; } 

        public object StatusCode { get; set; } 

        public string StatusText { get; set; } 

        public bool withCredentials { get; set; } 

    } 

} 

when I still use Syncfusion.EJ2.Blazor 17.2.0.46-beta it still good running, but after I upgrade to 17.2.0.47 I have trouble with DeserializeObject like in this img

Hi Erick,  

We would like to inform you, we have provided specific type for Success event instead of anonymous type. So, you can get the argument directly from SuccessEventArgs.  

Please find the code snippet and sample for your reference.
