Vue Data Grid: Loading 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.

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:

interface ILoadingCellRendererParams {
    // an optional template for the loading cell renderer
    loadingMessage?: string

    // The grid API
    api: GridApi;
}

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 ERROR MESSAGE ---',
            },
        };
        } else {
            // no loading cell renderer 
            return undefined;
        }
    }
}

Registering Loading Cell Renderer Components
