AjaxFileUpload after OnUploadComplete event

Question

User-1627226156 posted

In ASP.NET (Web Forms) I set a value to a Label control on the page load event and can display the value with a Button control. After uploading a file using the AjaxFileUpload control the OnUploadComplete event fires and at that time I try reading the value from the Label control mentioned earlier yet no value is returned.

Protected Sub AjaxFileUpload1_OnUploadComplete(ByVal sender As Object, ByVal e As AjaxFileUploadEventArgs)

Any assistance would be greatly appreciated.

Hi TimpthyV,

You can set the label value in a session then use the session value inside the AjaxFileUpload1_OnUploadComplete event.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    session("lblvale") = Label1.text
End Sub




Protected Sub FileUploader_UploadComplete(sender As Object, e As AjaxFileUploadEventArgs) Handles FileUploader.UploadComplete
   
   'use this session("lblvale")


End Sub

Rebin.O.Q,

My apologies for forgetting to mention that your solution worked perfectly. How kind of you to check back with me. The solution is below:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Session("Label1Value") = Label1.Text
End If
End Sub

Protected Sub AjaxFileUpload1_OnUploadComplete(ByVal sender As Object, ByVal e As AjaxFileUploadEventArgs)
MsgBox(Session("Label1Value"))
End Sub

Again much appreciated and all the best!
