OnClientFilesDropping

The client-side FilesDropping event is raised when the user drops the files for uploading in the file list of RadFileExplorer.

To handle this event, simply write a JavaScript function that can be called when the event occurs. Then assign the name of this function as the value of the OnClientFilesDropping property of the control.

The client-side OnClientFilesDropping event handler receives two arguments:

  1. Sender: The RadFileExplorer object that fired the event.

  2. Event arguments: A cancelable event arguments object of type Sys.CancelEventArgs that exposes the following methods:

    Table 1: OnClientFilesDropping Event Arguments Object

    Name Parameters Return Type Description
    get_cancel() Boolean Returns a value that indicates whether the event is cancelled.
    get_count() Integer Returns the count of the dropped items.
    get_dropArgs() Object Returns the drop arguments of the underlying RadAsyncUpload control.
    set_cancel(value) Boolean Sets whether the event will be cancelled (if true is passed).

Example 1: Handle the RadFileExplorer's client-side FilesDropping event.

<telerik:RadFileExplorer ID="RadFileExplorer1" runat="server"  OnClientFilesDropping="onClientFilesDropping">
    <Configuration ViewPaths="~/Images" DeletePaths="~/Images" UploadPaths="~/Images" />
</telerik:RadFileExplorer>
<script>
    function onClientFilesDropping(fileExplorer, args) {
        var filesCount = args.get_count();
        alert("You have are about to upload " + filesCount + " files.");
    }
