file upload isnt working in the updatepanel

Posted 30 July 2019 - 08:03 AM

hey all,

i have an upload control inside an update panel
the issue is that it returns null when uploading





  Dim _testName as String = fileUploadCompareExcel.PostedFile.FileName


  <div class="div1">
                                        <div class="div3">
                                            <asp:FileUpload ID="fileUploadCompareExcel"   runat="server"/>
                                        </div>
                                        <div class="div2">
                                            <asp:Button runat="server" ID="btnUploadCompare" text="Upload Compare" CssClass="btnStyle1" onclick="ImportCompareFile" OnClientClick="ShowProgress();"/>
                                            <asp:Button id="btnBack" runat="server" text="Go Back" CssClass="btnStyle1" OnClientClick="return Confirm();" onclick="SourceVisible"/>
                                        </div>
                                    </div>
                                </div>



update panel that code resides in

 <div><asp:UpdatePanel runat="server" id="upDating">
            <ContentTemplate>

                            <div class="divContainerMain">
 </ContentTemplate>
            <Triggers>
                <asp:PostBackTrigger ControlID="btnUploadCompare" />
            </Triggers>
        </asp:UpdatePanel></div>



i also put this in page load for testing:

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
       
        ScriptManager.GetCurrent(me).RegisterPostBackControl(me.btnUploadCompare)


no matter what it always returns null in the testName

Is This A Good Question/Topic? 0
