Overlays are used for displaying messages over the top of the grid. There are two built-in overlays: loading and no-rows.
Loading overlay
Show or hide the loading overlay by setting the loading
property to true
or false
.
Show or hide the loading overlay. |
The loading overlay takes precedence over the no-rows overlay and is not dependent of the state of rowData
.
No rows overlay
When rowData
is set to an empty array []
, the grid automatically displays the no-rows overlay. The no-rows overlay can also be programmatically shown / hidden via the grid API.
Show the no-rows overlay. If suppressNoRowsOverlay is set, or if loading is true, this will not do anything. |
Hide the no-rows overlay if it is showing. |
The automatic displaying of the no-rows overlay can be suppressed by setting suppressNoRowsOverlay
to true
.
Initial loading overlay
If loading
is not explicitly defined, the grid will automatically show the loading overlay until both rowData
and columnDefs
are provided with a non-null value for the first time. This behaviour can be suppressed by initialising the grid with an appropriate loading
state.
Customisation
Overlays can be customised by providing either a HTML string or custom component via grid properties.
Custom Loading Overlay
The loading overlay can be customised via the grid properties overlayLoadingTemplate
or loadingOverlayComponent
and loadingOverlayComponentParams
.
Provide a HTML string to override the default loading overlay. Supports non-empty plain text or HTML with a single root element. |
Provide a custom loading overlay component. |
Customise the parameters provided to the loading overlay component. |
This example demonstrates how to provide a custom loading overlay component customised via parameters.
Custom No Rows Overlay
The no-rows overlay can be customised via the grid properties overlayNoRowsTemplate
or noRowsOverlayComponent
and noRowsOverlayComponentParams
.
Provide a HTML string to override the default no-rows overlay. Supports non-empty plain text or HTML with a single root element. |
Provide a custom no rows overlay component. |
Customise the parameters provided to the no-rows overlay component. |
This example demonstrates how to provide a custom no-rows overlay component customised via parameters.
