ASP.NET Core ContextMenu Overview
The Telerik UI ContextMenu TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI ContextMenu widget.
The ContextMenu displays hierarchical data as a multi-level menu in a popup. It provides rich styling for unordered lists of items, and can be used for both navigation and execution of JavaScript commands.
Basic Usage
The following example demonstrates how to define the ContextMenu.
Razor
<div id="target">Click to open</div>
@(Html.Kendo().ContextMenu()
.Name("contextmenu")
.Target("#target")
.ShowOn("click")
.Items(items =>
{
items.Add()
.Text("Furniture") //Add an item with the text "Item1".)
.Items(children =>{
children.Add().Text("Sofas");
children.Add().Text("Chairs");
children.Add()
.Text("Tables")
.Items(i =>{
i.Add().Text("Dinning Tables");
i.Add().Text("Coffee Tables");
})
children.Add().Text("Accessories");
});
items.Add()
.Text("Electronics"); //Add an item with the text "Item2".)
.Items(children =>{
children.Add().Text("TVs");
children.Add().Text("Laptops");
});
})
)Configuration
The following example demonstrates the basic configuration of the ContextMenu HtmlHelper and how to get the ContextMenu instance.
Razor
<div id="target">Click to open</div>
@(Html.Kendo().ContextMenu()
.Name("contextmenu")
.Target("#target")
.ShowOn("click")
.Items(items =>
{
items.Add().Text("Item 1")
.ImageUrl(Url.Content("https://demos.telerik.com/kendo-ui/content/shared/icons/sports/baseball.png"))
.Items(children =>
{
children.Add().Text("Top News");
children.Add().Text("Photo Galleries");
children.Add().Separator(true);
children.Add().Text("Videos Records");
children.Add().Text("Radio Records");
});
items.Add().Text("Item 2")
.ImageUrl(Url.Content("https://demos.telerik.com/kendo-ui/content/shared/icons/sports/golf.png"))
.Items(children =>
{
children.Add().Text("Top News");
children.Add().Text("Photo Galleries");
children.Add().Separator(true);
children.Add().Text("Videos Records");
children.Add().Text("Radio Records");
});
items.Add().Text("Item 3")

.Items(children =>
{
children.Add().Text("Top News");
children.Add().Text("Photo Galleries");
});
})
.Animation(animation =>
{
animation.Open(fade => fade.Fade(FadeDirection.In));
animation.Open(open => open.Expand(ExpandDirection.Vertical));
})
.HoverDelay(500)
.Direction("left")
.Orientation(ContextMenuOrientation.Horizontal)
.Events(events => events
.Open("onOpen")
)
)
<script type="text/javascript">

var menu = $("#contextmenu").data("kendoContextMenu");
console.log(menu);
}
