Overlays are for displaying messages over the grid.
When using the Client-side Data the grid uses two overlays:
- Loading Overlay: Displayed if
rowDataorcolumnDefsare initially set tonullorundefined. - No Rows Overlay: Displayed if
rowDatais an empty list.
The example above demonstrates the default loading and no rows overlays.
Overlay API
You can manually show the overlays using the grid API.
Customisation
HTML templates can be provided to the overlays using grid properties.
Custom Overlays
This example demonstrates Custom Overlay Components.
Loading Overlays
Loading Overlay Component is configured via the grid properties loadingOverlayComponent and loadingOverlayComponentParams.
Implement this interface to provide a custom overlay when data is being loaded.
interface extends ILoadingOverlayAngularComp {
// mandatory methods
// The agInit(params) method is called on the overlay once.
agInit(params: ILoadingOverlayParams);
// optional methods
// Gets called when the `loadingOverlayComponentParams` grid option is updated
refresh(params: ILoadingOverlayParams): void;
}
The agInit(params) method takes a params object with the items listed below:
No Rows Overlays
No Rows Overlay Component is configured via the grid properties noRowsOverlayComponent and noRowsOverlayComponentParams.
Implement this interface to provide a custom overlay when no rows loaded.
interface extends INowRowsOverlayAngularComp {
// mandatory methods
// The agInit(params) method is called on the overlay once.
agInit(params: INoRowsOverlayParams);
// optional methods
// Gets called when the `noRowsOverlayComponentParams` grid option is updated
refresh(params: INoRowsOverlayParams): void;
}
The agInit(params) method takes a params object with the items listed below:
