AsyncUpload can't access addtional field on server side

[mohamed]

i can't access the additional fields server side :( i use telerik 2012.3)

i follow the following link :

http://demos.telerik.com/aspnet-ajax/asyncupload/examples/additionalfields/defaultcs.aspx

The script is:

function onClientFileUploaded(radAsyncUpload, args) {
    var row = args.get_row(),
        inputName = radAsyncUpload.getAdditionalFieldID("TextBox"),
        inputType = "text",
        inputID = inputName,
        input = createInput(inputType, "Title", "Title"),
        label = createLabel(inputID),
        br = document.createElement("br");

    row.appendChild(br);
    row.appendChild(input);
    row.appendChild(label);

}

function createInput(inputType, inputID, inputName) {
    var input = document.createElement("input");

    input.setAttribute("type", inputType);
    input.setAttribute("id", inputID);
    input.setAttribute("name", inputName);

    return input;
}

function createLabel(forArrt) {
    var label = document.createElement("label");

    label.setAttribute("for", forArrt);
    label.innerHTML = "info: ";

    return label;
}

My .aspx :

<telerik:RadAsyncUpload runat="server" ID="rada_attach" OnClientFileUploaded="onClientFileUploaded"
  MultipleFileSelection="Disabled" InitialFileInputsCount="1" MaxFileInputsCount="1"
  Width="100%" />

My .cs :

foreach (UploadedFile UF in rada_attach.UploadedFiles)

               {

                   OBJ.File_name = UF.GetFieldValue("Title");//always null


               }

Hello Mohamed,

Try to modify your JavaScript code as follows:

function onClientFileUploaded(radAsyncUpload, args) {
    var row = args.get_row(),
        inputName = radAsyncUpload.getAdditionalFieldID("Title"),
        inputType = "text",
        inputID = inputName,
        //input = createInput(inputType, "Title", "Title"),
        input = createInput(inputType, inputID, inputName),
        label = createLabel(inputID),
        br = document.createElement( "br" );

    row.appendChild(br);
    row.appendChild(input);
    row.appendChild(label);
}

This change was needed because to find the value of custom filed the GetFieldValue() method internally needs the correct InputName, returned by radAsyncUpload.getAdditionalFieldID("Title"). This allows the control to know where to look for this custom filed, for example if you have multiple uploaded files you will have multiple custom fields. Please test it and let me know if it resolves the issue.

All the best,
