TileLayout Overview
The Telerik UI TileLayout TagHelper for ASP.NET Core is a server-side wrapper for the Kendo UI TileLayout widget.
The TileLayout widget allows you configure a two-dimensional grid-based sandbox surface to display content in tiles which can be dragged around and rearranged to create any modern page design.
It is based on the CSS Grid(with all its features) which covers the majority of cases and uses additional JavaScript logic to provide resizing, reordering and templates customizations.
The TileLayout 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.
Initializing the Tile Layout
To initialize the Tile Layout, specify the number of columns at root level and use the row-span and col-span of the containers to position the content in the available grid space.
The example below will render a grid with two columns which can be resized both vertically and horizontally.
<kendo-tilelayout name="tilelayout" columns="2" resizable="true" reorderable="true" columns-width="300px" rows-height="300px">
<containers>
<container body-template="Template One" col-span="1" row-span="1">
<container-header text="One" />
</container>
<container body-template="Template Two" col-span="1" row-span="1">
<container-header text="Two" />
</container>
<container body-template="Template Three" col-span="2" row-span="1">
<container-header text="Three" />
</container>
</containers>
</kendo-tilelayout>
Grid Layout configuration
The Telerik UI TileLayout TagHelper for ASP.NET Core available grid space is defined by using the columns attribute. The number of rows in which the tiles will be displayed will automatically adjust. The columns and rows have a default width of 1fr which can be modified by using the columns-width and rows-height attributes.
The
rows-heightandcolumns-widthattributes value sets the maximum height/width the rows or columns of the widget will stretch to. Dependent on resizing, content and user interactions with the layout, they may be less than the set value.
Tile Layout configuration
Each tile can span across several rows and columns. The space that the tile takes up is determined by its container row-span and col-span. For more information about the containers and their configurable properties, see the containers article.
Gaps
The grid lines between the rows and columns can be configured by specifying the gaps columns tag for the vertical space between the tiles and the gaps rows tag for the horizontal spacing.
<kendo-tilelayout name="tilelayout" columns="2" resizable="true" reorderable="true" columns-width="300px" rows-height="300px">
<gap rows="10" columns="10" />
These properties are also known as the gutters between the rows/columns.
Referencing Existing Instances
To get a reference to an existing TileLayout instance:
- Use the
jQuery.data()method. -
Once a reference is established, use the TileLayout API to control its behavior.
var tilelayout = $("#tilelayout").data("kendoTileLayout");
Resizing
To enable resizing both horizontally and vertically, use the resizable attribute:
<kendo-tilelayout name="tilelayout" columns="3" resizable="true">
Reordering
To enable reordering of the tiles, use the reorderable attribute:
<kendo-tilelayout name="tilelayout" columns="3" reorderable="true">
Containers
To define the containers, use the <containers> tag and nest the number of <container> tags necessary to achieve the desired design.
<containers>
<container body-template-id="crayons" col-span="1" row-span="1">
<container-header text="Crayons" />
</container>
Container Styles
The TileLayout exposes an object that allows you to override the following styles:
var tileLayoutStyles = {
wrapper: "k-widget k-tilelayout",
item: "k-tilelayout-item k-card",
itemHeader: "k-tilelayout-item-header k-card-header",
itemHeaderTitle: "k-card-title",
itemBody: "k-tilelayout-item-body k-card-body",
reorderHint: "k-layout-item-hint k-layout-item-hint-reorder",
resizeHint: "k-layout-item-hint k-layout-item-hint-resize"
};
To override any of the classes, add your own or remove some, insert the new definition before the widget is initialized:
kendo.ui.TileLayout.styles.item = "k-tilelayout-item k-card my-own-class";
Event handling
The TileLayout emits two events resize and reorder. To capture them, use the on-[eventName] attribute.
<kendo-tilelayout name="tilelayout" columns="3" reorderable="true" on-reorder="onReorder">
<script>
function onReorder(e) {
console.log(e.newIndex, e.oldIndex);
}
</script>
Known Limitations
Currently, the component is not supported in Internet Explorer as the browser does not support gutters.
