Hello,

You can control the toolbar visibility from client-side code. The code below illustrates how to achieve it.

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head id="Head1" runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<script type="text/javascript">

function configureToolbarItems(fileExplorer)

{

//Get a reference to the RadFileExplorer's toolbar

var toolbar = fileExplorer.get_toolbar();

//Get commands client-side objects

var delCommand = toolbar.findItemByValue("Delete");

var newFolderCommand = toolbar.findItemByValue("NewFolder");

var treeView = fileExplorer.get_tree();

var currentlySelectedNode = treeView.get_selectedNode();

if(currentlySelectedNode.get_parent() == treeView)

{

//Disable Delete and Enable NewFolder

delCommand.set_visible(false);

newFolderCommand.set_visible(true);

}

else

{

//Enable Delete and Disble NewFolder

delCommand.set_visible(true);

newFolderCommand.set_visible(false);

}

function ItemSelected(fileExplorer, args)

{

configureToolbarItems(fileExplorer);

}

function OnClientFolderChange(fileExplorer, args)

{

configureToolbarItems(fileExplorer);

}

</script>

<div>

<telerik:RadFileExplorer ID="RadFileExplorer1" runat="server"

OnClientItemSelected="ItemSelected"

OnClientFolderChange = "OnClientFolderChange">

<Configuration ViewPaths="~/Files" DeletePaths="~/Files" UploadPaths="~/Files"/>

</telerik:RadFileExplorer>

</div>

</form>

</body>

</html>

Also you can handle RadFileExplorer's OnItemCommand server-side event and make additional checks,e.g.

protected void fileExplorer_ItemCommand(object sender, RadFileExplorerEventArgs e)

{

switch (e.Command)

{

case "UploadFile":

//DO SOMETHING

break;

case "CreateDirectory":

//DO SOMETHING

break;

case "DeleteFile":

//DO SOMETHING

break;

}

Hope this helps.

Sincerely yours,
