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.
<div>
<!-- Declare button element -->
@Html.EJS().Button("enable").Content("Enable New Folder toolbar item").CssClass("e-success").Render()
@Html.EJS().Button("disable").Content("Disable New Folder toolbar item").CssClass("e-danger").Render()
<!-- end of button element -->
</div>
<div class="control-section">
<div class="sample-container">
<!-- Declare filemanager element -->
@Html.EJS().FileManager("filemanager").AjaxSettings(new Syncfusion.EJ2.FileManager.FileManagerAjaxSettings
{
Url = "/Home/FileOperations",
GetImageUrl = "/Home/GetImage",
UploadUrl = "/Home/Upload",
DownloadUrl = "/Home/Download"
}).View(Syncfusion.EJ2.FileManager.ViewType.Details).Render()
<!-- end of filemanager element -->
</div>
</div>
<script>
document.addEventListener('DOMContentLoaded', function () {
var filemanagerInstance = document.getElementById("filemanager").ej2_instances[0];
// Click event for enable button
document.getElementById("enable").onclick = function (args) {
// Enable new folder toolbar item
filemanagerInstance.enableToolbarItems(["newfolder"]);
}
// Click event for enable button
document.getElementById("disable").onclick = function (args) {
// Disable new folder toolbar item
filemanagerInstance.disableToolbarItems(["newfolder"]);
}
});
