Hi Cahya,
Greetings from Syncfusion support.
From your query we can understand that you only want to use the Grid and textbox particularly instead of using all components to optimize the page loading speed.
So we suggest you to download the Grid and Textbox code in a single file and refer to the sample. Because sometimes the two different components may have same dependencies and which cause the reported issue while referring them into separate files. We can avoid this by selecting all the required components in a single file. Please refer the below screenshot and sample for more information.
In our latest version of CRG we are having some issues in grid component and we have logged a new bug task (“Script error is thrown while creating sample using CRG file”) for the same. We will include the defect fix in our upcoming Volume 2, 2021 Main release which will be expected to rolled out in the month of June.
You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.
Until the fix has been included we suggest you to use the lower versions(Ex: 19.1.54) of CRG for your requirement.
Regards,
Manivel
