Upload: Uncaught TypeError: Cannot call method 'get_selectedItem' of null

[Ajit]

Hi,

When I try to upload a file using FileExplorer, the update panel keeps showing long after the file upload.

In the Chrome console, this script error appears:

Uncaught TypeError: Cannot call method 'get_selectedItem' of null

Here's the declaration of the FileExplorer:

<telerik:RadFileExplorer ID="ExplorerExportTemplates" runat="server" Width="600px" Height="400px"
                                                            Skin="Metro" Configuration-AllowFileExtensionRename="False" Configuration-AllowMultipleSelection="False"
                                                            AllowPaging="true" EnableOpenFile="true" EnableAsyncUpload="True">
                                                            </telerik:RadFileExplorer>

Here's the code-behind:

string[] paths = new string[] { Page.ResolveUrl(fullPath) };
                ExplorerExportTemplates.Configuration.ViewPaths = paths;
                ExplorerExportTemplates.Configuration.UploadPaths = paths;
                ExplorerExportTemplates.Configuration.DeletePaths = paths;
                ExplorerExportTemplates.Configuration.EnableAsyncUpload = true;
                ExplorerExportTemplates.Configuration.MaxUploadFileSize = 104857600;
                ExplorerExportTemplates.Configuration.AllowFileExtensionRename = false;
                ExplorerExportTemplates.Configuration.AllowMultipleSelection = false;
                ExplorerExportTemplates.EnableCreateNewFolder = true;
                ExplorerExportTemplates.EnableCopy = false;
                ExplorerExportTemplates.ExplorerMode = Telerik.Web.UI.FileExplorer.FileExplorerMode.FileTree;
                ExplorerExportTemplates.Configuration.SearchPatterns = new string[] { "*.xls", "*.xlsx" };
                ExplorerExportTemplates.Configuration.ContentProviderTypeName = typeof(Telerik.Web.UI.Widgets.FileSystemContentProvider).AssemblyQualifiedName;

Any ideas?

Thanks,

Ajit

Hello Ajit,

I tried to reproduce the reported error but to no avail. Could you please provide more detailed information on the specific scenario?

• Which version of RadControls for ASP.NET AJAX and .NET Framework are used in the application?
• Are you able to reproduce the problem on the live demos? If so, could you please provide the exact steps the need to be executed in order to reproduce the issue?
• Could you please provide a simple fully runnable project reproducing the problem so we can investigate it further?

For your convenience I have created a video demonstrating my test, could you please see if I am missing something?
