Vue Data GridLoading Cell Renderer

Loading cell renderers allow you to add your own loading renderers to AG Grid. Use these when the provided loading renderers do not meet your requirements.

Simple Loading Cell Renderer Component

Below is a simple example of loading cell renderer component:

const MyRenderer = {
   template: `
     <div class="ag-custom-loading-cell" style="padding-left: 10px; line-height: 25px;">
         <i class="fas fa-spinner fa-pulse"></i> <span>{{ params.loadingMessage }}</span> </div>`
}

Example: Custom Loading Cell Renderer

The example below demonstrates how to provide custom loading cell renderer component to the grid. Notice the following:

  • Custom Loading Cell Renderer is supplied by name via gridOptions.loadingCellRenderer.
  • Custom Loading Cell Renderer Parameters are supplied using gridOptions.loadingCellRendererParams.
  • Example simulates a long delay to display the spinner clearly.
  • Scrolling the grid will request more rows and again display the loading cell renderer.

Loading Cell Renderer Component

Any valid Vue component can be a Loading Cell Renderer Component.

When a custom Loading Cell Renderer Component is instantiated within the the grid the following will be made available on this.params:

ILoadingCellRendererParams

Properties available on the ILoadingCellRendererParams<TData = any, TContext = any> interface.

node
IRowNode
The row node.
api
GridApi

columnApi
ColumnApi

context
TContext

Dynamic Cell Loading Renderer

It's possible to determine what Loading Cell Renderer to use dynamically - i.e. at runtime. For this you'll make use of the

loadingCellRendererSelector: (params) => {
   const useCustomRenderer = ...some condition/check...
   if (useCustomRenderer) {
       return {
           // the component to use - registered previously
           component: 'customLoadingCellRenderer',
           params: {
               // parameters to supply to the custom loading cell renderer
               loadingMessage: '--- CUSTOM LOADING MESSAGE ---',
           },
       };
       } else {
           // no loading cell renderer
           return undefined;
       }
   }
}
