Hi Narsa,

Would you specify where do you define RadAsyncUpload? Is it in the code behind? How do you upload files? The described issue could not be reproduced from the pasted markup. Please send a runnable sample with steps to reproduce so we can debug your code and troubleshoot the problem.

Hi,

This problem solved myself.

When I am uploading file from upload control then showing file name in to other textbox.

Protected Sub AttachmentGrid_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)

If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then

Dim item As GridEditableItem = TryCast(e.Item, GridEditableItem)

Dim upload As RadUpload = (TryCast(item.EditManager.GetColumnEditor("AttachmentColumn"), GridAttachmentColumnEditor)).RadUploadControl

upload.OnClientFileSelected = "uploadFileSelected"

End If

End Sub

function uploadFileSelected(sender, args) {

upload = sender;

var uploadContainer = sender.get_element();

var editTable = uploadContainer.parentNode.parentNode.parentNode.parentNode;

var fileNameTextBox = editTable.rows[7].cells[1].getElementsByTagName('input')[0];

fileNameTextBox.value = showFile(args.get_fileInputField().title);

}

From above code i have given wrong row index (editTable.rows[6].cells[1] ) , So then it's throwing an JSON error.

I dont know why If i give wrong row index throwing JSON error..

Thank you.
