I use the AsyncUpload
<telerik:RadAsyncUpload runat="server" ID="rada_attach" OnClientFileUploaded="onClientFileUploaded"
MultipleFileSelection="Disabled" InitialFileInputsCount="1" MaxFileInputsCount="1"
Width="100%" />
function onClientFileUploaded(radAsyncUpload, args) {
var row = args.get_row(),
inputName = radAsyncUpload.getAdditionalFieldID("TextBox"),
inputType = "text",
inputID = inputName,
input = createInput(inputType, inputID, inputName),
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;
}
I want to access the textbox (which created dynamically) in .cs.
How to do that ?
The Full Answer :
var $ = $telerik.$;
function onClientFileUploaded(radAsyncUpload, args) {
var $row = $(args.get_row());
var inputName = radAsyncUpload.getID("TextBox");
var inputType = "text";
var inputID = inputName;
var input = createInput(inputType, inputID, inputName);
var label = createLabel(inputID);
$row.append("<br/>");
$row.append(label);
$row.append(input);
}
function createInput(inputType, inputID, inputName) {
var input = '<input type="' + inputType + '" id="' + inputID + '" name="' + inputName + '" />';
return input;
}
function createLabel(forArrt) {
var label = '<label for=' + forArrt + '>info: </label>';
return label;
}
foreach (UploadedFile UF in rada_attach.UploadedFiles)
{
if (UF.GetFieldValue("TextBox") != null)
{
OBJ.File_name = UF.GetFieldValue("TextBox");
}
else
{
OBJ.File_name = UF.GetName();
}
In my opinion documentation is well clear. Check the Description tab on page you refer on. You can access value of dynamic textboxes with code below on postback:
if (rada_attach.UploadedFiles.Count > 0) {
for (var index = 0; index < rada_attach.UploadedFiles.Count; ++index) {
var textBoxValue = rada_attach.UploadedFiles[index].GetFieldValue("TextBox");
}
}
BTW, this scenario is well-dcoumented here: Adding Information to Uploaded Files
You need to check the Request.Form
values (that were in the posted form) on postback and perform a check on all the fields that were posted back.
I am guessing that you won't know the name/id of the textbox if it was created on the client-side dynamically? Note that it would be the name
of the form field that the Request
object in .cs would see.
Only once you have posted back can you access that value in the .cs
