how to call controller action from menu item click and pass info to the action, like current object and Id in ASP .Net Core.
In ASP.NET Core, one can call a controller action with an additional parameter, such as the current object ID and object, from a menu item using the select event. This can be achieved by retrieving the selected item and then making an AJAX call to pass the menu item object or ID to the controller. An example is provided below.
[Index.cshtml]:
<div class="menu-control">
<ejs-menu id="menu" items="menuItems" select="onSelect"></ejs-menu>
</div>
<script>
function onSelect(args) {
var value = { Id: args.item.id, Text: args.item.text };
var ajax = new ej.base.Ajax({
url: "@Url.Action("GetRedirectUrl", "home")",
data: JSON.stringify(value),
type: 'POST',
contentType: 'application/json; charset=utf-8',
dataType: "json"
});
ajax.send().then(function (response) {
window.location.href = response.redirectToUrl;
}).catch(function () {
});
}
</script>

Once the values have been obtained from the AJAX call, they can be passed to other pages by using the "redirectToUrl" function to redirect to the appropriate URL. An example is provided below.
[HomeController.cs]:
public class HomeController : Controller
{
public IActionResult Index()
{
return View();
}
[HttpPost]
public IActionResult GetRedirectUrl([FromBody] MenuItem value)
{
return Json(new { redirectToUrl = Url.Action(value.Text, "Home", new { Id = value.Id }) });
}
public IActionResult Open(MenuItem item)
{
return View(item);
}
public IActionResult Save(MenuItem item)
{
return View(item);
}
}
Please find the below code snippets to define the MenuItem class in Models.
[ErrorViewModel.cs]:
public class MenuItem
{
public string Id { get; set; }
public string Text { get; set; }
}
When a user clicks on a menu item, the page is loaded via the controller with the passed ID value.
[Open.cshtml]:
@model CoreWebApp.Models.MenuItem <h2>Open item is clicked</h2> <br/> <h3>Selected Id: @Model.Id</h3>
Output screenshot:
[Save.cshtml]:
@model CoreWebApp.Models.MenuItem <h2>Save item is clicked</h2> <br/> <h3>Selected Id: @Model.Id</h3>
