AutoComplete in Razor Pages
Razor Pages is an alternative to the MVC pattern that makes page-focused coding easier and more productive. This approach consists of a cshtml file and a cshtml.cs file (by design, the two files have the same name).
You can seamlessly integrate the Telerik UI AutoComplete for ASP.NET Core in Razor Pages applications.
This article showcases how to configure the AutoComplete component in a Razor Pages scenario.
For the complete project, refer to the AutoComplete in Razor Pages example.
Getting Started
In order to set up the AutoComplete component bindings, you need to configure the Read method of its DataSource instance. The URL in this method should refer the name of the method in the PageModel. In this method, you can also pass additional parameters, such as filter string and antiforgery token (see dataFunction).
@model IndexModel
@inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf
@Html.AntiForgeryToken()
@(Html.Kendo().AutoCompleteFor(model => model.ShipName)
.DataTextField("ShipName")
.Filter("contains")
.MinLength(3)
.HtmlAttributes(new { style = "width:100%" })
.DataSource(ds => ds
.Custom()
.Transport(transport => transport
.Read(r => r
.Url("/AutoComplete/AutoCompleteCRUDOperations?handler=Read").Data("dataFunction")
))
.ServerFiltering(true)
)
)
<script>
function dataFunction() {
var value = $("#autocomplete").val();
return {
__RequestVerificationToken: kendo.antiForgeryTokens().__RequestVerificationToken,
filterValue: value
};
}
</script>
<kendo-autocomplete for="ShipName"
datatextfield="ShipName"
filter="FilterType.Contains"
min-length="3">
<datasource type="DataSourceTagHelperType.Custom"
server-filtering="true">
<transport>
<read url="/AutoComplete/AutoCompleteCRUDOperations? handler=Read" data="dataFunction" />
</transport>
</datasource>
</kendo-autocomplete>
public class IndexModel : PageModel
{
[BindProperty]
public string ShipName { get; set; }
public JsonResult OnGetRead(string filterValue)
{
if (filterValue != null)
{
//orders is the DBContext
var filteredData = orders.Where(p => p.ShipName.Contains (filterValue));
return new JsonResult(filteredData);
}
return new JsonResult(orders);
}
}
