Column Menu
The column menu allows users to quickly access column-related operations like sorting and filtering.
To enable the column menu, use the ColumnMenu(true) method. As a result, the column headers of the Grid render a column menu, which allows the user to sort, filter, or change the visibility of a column. The column menu also detects when a specific column operation is disabled through the column definition and excludes the corresponding UI from rendering. For a runnable example, refer to the demo on implementing a column menu in the Grid.
As of the R3 2022 release, the Grid also provides the option to set this property on individual Column level. You can disable the menu for a specific column by setting it to
.ColumnMenu(false).
Column Reordering
As of Telerik UI for ASP.NET Core R2 SP1 2023, the Grid's Column Menu provides an option to change the position of the target column by using Move next and Move previous buttons. The functionality requires that reordering for the columns is enabled.
@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.OrderViewModel>()
.Name("grid")
.Reorderable(reorder => reorder.Columns(true))
)
<kendo-grid name="grid">
<reorderable enabled="true" columns="true"/>
</kendo-grid>
To see this functionality in action, check the Grid Column Menu demo.
Column Grouping
As of Telerik UI for ASP.NET Core R2 SP1 2023, the Grid's Column Menu provides an option that allows users to select the target column for grouping or ungrouping the Grid. To display the option item in the Column Menu, enable grouping via the Groupable configuration.
Sort
The column menu allows you to control the visibility of each Grid column. For this purpose, the column menu renders a child column menu with a checkbox for each Grid column.
By default, the Grid column titles in the child column menu are not sorted. They have the same order as the columns in the Grid. To sort the column titles in the child menu, use the ColumnMenu() method.
The below example demonstrates how to sort the column titles in the child menu in ascending order:
.ColumnMenu(menu=>
menu.Columns(columns => columns.Sort("asc"))
)
<column-menu>
<column-menu-columns sort="asc">
</column-menu-columns>
</column-menu>
Group
The ColumnMenu() method accepts a GridColumnMenuSettingsBuilder that enables grouping of the columns in the child menu. The Columns() group method expects a collection of the model properties. The menu will automatically use the title of the grid columns if such is defined
The following example demonstrates how to group columns by providing the model fields in a list of strings:
.ColumnMenu(menu=>
menu.Columns(columns => {
columns.Groups(groups =>
{
groups.Add().Title("Company Info").Columns(new List<string> { "CompanyName", "Country" }); ;
groups.Add().Title("Contact Info").Columns(new List<string> { "ContactName", "ContactTitle" });
});
})
)
<column-menu>
<column-menu-columns sort="asc">
<column-menu-columns-groups>
<column-menu-columns-group title="Company Info" columns='new string[] { "CompanyName", "Country" }' />
<column-menu-columns-group title="Contact Info" columns='new string[] { "ContactName", "ContactTitle" }' />
</column-menu-columns-groups>
</column-menu-columns>
</column-menu>
Column Menu Types
The Telerik UI for ASP.NET Core Grid provides the following Column Menu component types:
| Column Menu Type | Description |
|---|---|
classic |
The default rendering mode of the Grid's Column Menu |
modern |
Introduced with R1 2021 version of the Telerik UI for ASP.NET Core suite. The modern rendering mode aims to deliver a fresh look and feel to the Grid's Column Menu |
tabbed |
Introduced with R3 SP1 2023 version of the Telerik UI for ASP.NET Core suite. The tabbed component type delivers a more compact view without sacrificing the available space. The tabbed interface provides a neat way to organize items into related groups. |
By default, the column menu of the Grid is initialized in the classic render mode. To set it to modern or tabbed, configure the ColumnMenu.ComponentType option of the Telerik UI for ASP.NET Core Grid as demonstrated below:
@(Html.Kendo().Grid()
.Name("datePicker")
.ColumnMenu(m=>{
m.ComponentType("tabbed");
})
)
<kendo-grid name="grid">
<column-menu component-type="tabbed">
</column-menu>
</kendo-grid>
