ASP.NET Core Grid Overview
The Grid is part of Telerik UI for ASP.NET Core, a
professional grade UI library with 110+ components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.
The Telerik UI Grid TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI Grid widget. To add the component to your ASP.NET Core app, you can use either.
The Grid is a powerful control for displaying data in a tabular format. It provides options for executing data operations, such as paging, sorting, filtering, grouping, and editing, which determine the way the data is presented and manipulated. The Grid supports data binding to local and remote sets of data by using the Kendo UI for jQuery DataSource component.
Initializing the Grid
The following example demonstrates how to define the Grid.
@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.Customer>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(c => c.ContactName).Width(140);
columns.Bound(c => c.ContactTitle).Width(190);
columns.Bound(c => c.CompanyName);
columns.Bound(c => c.Country).Width(110);
})
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("Customers_Read", "Grid"))
)
)
<kendo-grid name="grid">
<columns>
<column field="ContactName" width="140"></column>
<column field="ContactTitle" width="190"></column>
<column field="CompanyName"></column>
<column field="Country" width="110"></column>
</columns>
<datasource type="DataSourceTagHelperType.Ajax">
<transport>
<read url="@Url.Action("Customers_Read","Grid")"/>
</transport>
</datasource>
</kendo-grid>
public class GridController : Controller
{
public ActionResult Customers_Read([DataSourceRequest] DataSourceRequest request)
{
var result = Enumerable.Range(0, 50).Select(i => new Customer
{
CompanyName = "Company Name " + i,
ContactName = "Contact Name " + i,
ContactTitle = "Contact Title " + i,
Country = "Coutry " + i
});
var dsResult = result.ToDataSourceResult(request);
return Json(dsResult);
}
}
public class Customer
{
public string ContactName { get; set; }
public string CompanyName { get; set; }
public string Country { get; set; }
public string ContactTitle { get; set; }
}
Basic Configuration
The Grid configuration options are passed as attributes of the helper. The Grid uses the DataSource component to bind its data.
To parse the value to a proper data type, set a
typefield in the DataSource schema model of the Grid HtmlHelper or TagHelper.
@(Html.Kendo().Grid<TelerikAspNetCoreApp4.Models.OrderViewModel>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(p => p.OrderID).Width(120);
columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}");
columns.Bound(p => p.ShipName).Width(300);
columns.Bound(p => p.ShipCity).Width(250);
})
.Groupable()
.Sortable()
.Filterable()
.Pageable(pageable => pageable
.ButtonCount(5)
.Refresh(true)
.PageSizes(new[] { 5, 10, 20 }))
.DataSource(dataSource => dataSource
.Custom()
.Transport(transport => transport
.Read(read => read.Action("Orders_Read", "Grid")))
.Schema(schema => schema
.Data("Data")
.Model(model => {
model.Field("OrderDate", typeof(DateTime));
})
)
)
)
<kendo-grid name="grid" height="550">
