My custom component for a custom cell is created using Typescript:

1.import {GridCellProps} from '@progress/kendo-react-grid';
2. 
3.export class CustomCell extends React.Component<Readonly<GridCellProps>> {
4.    ...
5.}

I am trying to pass a custom prop to it: 

MyCustomCell = (props) => <CustomCell {...props} myProp={this.customData} />

But get the error:
Property 'myProp' does not exist on type 'Readonly<Readonly<GridCellProps>> & Readonly<{ children?: ReactNode; }>'.

How can I get past the TS constraint?

Hello,

This is expected as myProp is not part of the GridCellProps interface.

This can be resolved by passing `any` to the props type instead of GridCellProps, as this is a custom cell and it is expected to have different props.

Using GridCellProps is not required in this case, and can be replaced with no issues.

If you still prefer to keep all GridCellProps, a new interface MyCustomCellProps can be done that will extend the GridCellProps and add the new props like myProp and more.
