Toolbar Commands
The Telerik UI for ASP.NET MVC FileManager component contains a nested Telerik UI for ASP.NET MVC Toolbar component.
The toolbar has a predefined set of tools which you can show or hide, depending on your preferences and business scenario. By default, the toolbar contains the following tools:
- New Folder button, allowing you to create new folders in the current location.
- Upload Button prompting you with a window to upload files.
- Sort By dropdown, allowing you to sort by a number of predicates
- Views button group to control
- View Details switch button to toggle the Preview Pane visibility
- Search textbox to filter the content
Inbuilt Sort functionality in Telerik UI for ASP.NET MVC FileManager:
Customizing the Toolbar Commands
To Enable/Disable a Toolbar command button or update the its text you can use the Toolbar.Items() configuration option:
.Toolbar(toolbar => toolbar.Items(items =>
{
items.Add("").Text("Add New Folder").Enable(false).Command("CreateFolderCommand").Type("button");
}))
Adding Custom Commands to the Toolbar
As of Kendo UI R1 2020 SP1 the kendo.ui.filemanager namespace exposes the FileManagerCommand class that could be extended to implement a custom FileManager command. The example below demonstrates how to create a custom command that shows the total size of the selected files.
First, create a new command by extending the FileManagerCommand class.
<script>
var filemanagerNS = kendo.ui.filemanager;
filemanagerNS.commands.MyCustomCommand = filemanagerNS.FileManagerCommand.extend({
exec: function () {
var that = this,
filemanager = that.filemanager, // get the kendo.ui.FileManager instance
options = that.options, // get the options passed through the tool
target = options.target, // options.target is available only when command is executed from the context menu
selectedFiles = filemanager.getSelected(); // get the selected files
var totalSize = 0;
selectedFiles.forEach(function (fileEntry) {
totalSize += fileEntry.size;
});
kendo.alert(selectedFiles.length + ' file(s) selected; Total size: ' + kendo.getFileSizeMessage(totalSize))
}
});
</script>
Then add the custom command to the FileManager Toolbar:
.Toolbar(toolbar => toolbar.Items(items =>
{
items.Add("").Type("button").Name("GetInfo").Text("Get Info").Command("MyCustomCommand");
}))
You can also add the custom command to the ContextMenu of the FileManager
.ContextMenu(context => context.Items(items =>
{
items.Add("rename");
items.Add("delete");
items.Add("custom").Name("GetInfo").Text("Get Info").Command("MyCustomCommand").SpriteCssClass("k-icon k-i-info");
}))
