Razor Page
This article describes how to configure a Remote DataSource of a Telerik AutoComplete in a RazorPage scenario.
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
). See the implementation details in the example below, and for the full project with RazorPages examples, visit our GitHub repository.
@inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf
@Html.AntiForgeryToken()
@(Html.Kendo().AutoComplete()
.Name("autocomplete")
.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 name="autocomplete"
datatextfield="ShipName"
filter="FilterType.Contains"

<datasource type="DataSourceTagHelperType.Custom"
server-filtering="true">
<transport>
<read url="/AutoComplete/AutoCompleteCRUDOperations?handler=Read" data="dataFunction" />
</transport>
</datasource>
</kendo-autocomplete>
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);
}
