The client-side ItemSelected event is raised when a file/folder is selected in the grid 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 OnClientItemSelected property of the control.

Example 1 shows how to detect the item selection, and then determine whether the selected item is a directory or a file.

The client-side OnClientItemSelected event handler receives two arguments:

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

  2. Event arguments: An event arguments object of type Telerik.Web.UI.FileExplorerEventArgs that exposes the following methods:

    Table 1: OnClientItemSelected Event Arguments Object

    Name Parameters Return Type Description
    get_cancel() Boolean Returns a value that indicates whether the event is cancelled.
    get_item() Object Returns a reference to the selected file/folder.
    get_path() String Returns the path to the selected file/folder.
    set_cancel(value) Boolean Sets whether the event will be cancelled (if true is passed).

Example 1: Detect file selection by handling the RadFileExplorer's client-side ItemSelected event.

<telerik:RadFileExplorer ID="RadFileExplorer1" runat="server"  OnClientItemSelected="onClientItemSelected">
    <Configuration ViewPaths="~/Images" DeletePaths="~/Images" UploadPaths="~/Images" />
    function onClientItemSelected(fileExplorer, args) {
        if (args.get_item().get_type() == Telerik.Web.UI.FileExplorerItemType.File) {
            // if the item is a file        
            var file = "File path : " + args.get_item().get_path() + "\n";
            file = file + "File size : " + args.get_item().get_size();
            alert("Selected file: \n" + file);
        else {
            // if the item is a folder        
            alert("The selected item is a directory");
