The toolbar items can be enabled/disabled by specifying the items in enableToolbarItems or disableToolbarItems methods respectively.
The following example shows enabling and disabling toolbar items on button click.
var hostUrl = 'https://ej2-aspcore-service.azurewebsites.net/';
// inject feature modules of the file manager
ej.filemanager.FileManager.Inject(ej.filemanager.DetailsView,ej.filemanager.Toolbar,ej.filemanager.NavigationPane);
// initialize File Manager component
var filemanagerInstance = new ej.filemanager.FileManager({
ajaxSettings: {
url: hostUrl + 'api/FileManager/FileOperations',
getImageUrl: hostUrl + 'api/FileManager/GetImage',
uploadUrl: hostUrl + 'api/FileManager/Upload',
downloadUrl: hostUrl + 'api/FileManager/Download'
},
height: "330px"
});
// render initialized File Manager
filemanagerInstance.appendTo('#filemanager');
// Click event for enable button
document.getElementById("enable").onclick = function(args) {
// Enable new folder toolbar item
filemanagerInstance.enableToolbarItems(["newfolder"]);
}
// Click event for disable button
document.getElementById("disable").onclick = function(args) {
// Disable new folder toolbar item
filemanagerInstance.disableToolbarItems(["newfolder"]);
