Steps to reproduce:

http://demos.telerik.com/aspnet-ajax/fileexplorer/examples/overview/defaultcs.aspx

       1.  Delete Flower3.jpg
       2.  Rename Flower5 to Flower3

Actual: The image with Flower3 name has changed to the one which was deleted

Cross folder searching/filtering please.

RadFileExplorer only natively works with standard Windows files that are on the server.  This precludes us from effectively using Azure's data structures, especially blob and the newer file types. With things like Webjobs where there is no standard file structure, we need the ability to access files that are stored in a shared space.

FileExplorer built-in features I would like to see:
1. Support for UNC paths so that the root folder may be located in a network share as opposed to a folder under the application folder.
2. Support for sub-pathing so that it can be dynamically programmed to support direct display of target folder without having to navigate to the target folder
3. Built-in Delete function to complement the built-in Upload function
4. Optional display of checkbox column to allow for multiple selection for items to be Deleted or Downloaded
5. Built-in Progress Bar for Upload and Download functions

At present, when an invalid file is selected, the alert message does not clearly indicate what is the validation error - invalid extension or the size being too large. It should show a message that clearly states what the problem is so the user can fix it.


For the time being you can handle the AsyncUpload's OnClientValidationFailed event and show different messages—http://docs.telerik.com/devtools/aspnet-ajax/controls/asyncupload/client-side-programming/onclientvalidationfailed.

Example:

ASP.NET
-------------------------------
<telerik:RadFileExplorer runat="server" ID="RadFileExplorer1">
    <Configuration ViewPaths="~/" UploadPaths="~/" DeletePaths="~/" SearchPatterns="*.jpg" />
</telerik:RadFileExplorer>

<script>
    // Prevent the built-in validation alert
    Telerik.Web.UI.RadFileExplorer.prototype._showUploadValidationFailedAlert = function () {

    }

    function OnClientValidationFailed(sender, args) {
        var fileExtention = args.get_fileName().substring(args.get_fileName().lastIndexOf('.') + 1, args.get_fileName().length);
        if (args.get_fileName().lastIndexOf('.') != -1) {//this checks if the extension is correct
            if (sender.get_allowedFileExtensions().indexOf(fileExtention) == -1) {
                alert("Wrong Extension!");
            }
            else {
                alert("Wrong file size!");
            }
        }
        else {
            alert("not correct extension!");
        }
    }
</script>
-------------------------------

C#
-------------------------------
RadFileExplorer1.AsyncUpload.OnClientValidationFailed = "OnClientValidationFailed";
-------------------------------

VB
-------------------------------
RadFileExplorer1.AsyncUpload.OnClientValidationFailed = "OnClientValidationFailed"
-------------------------------

Provide the ability to drag/drop files into the Treeview/GridView of RadFileExplorer and automatically upload them. Currently this option is offered only over the RadAsyncUpload area inside the Upload dialog of RadFileExplorer.
