Hi @ganuzaz. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The useExport hook in refine fetches data in batches, and by default, it fetches 20 items per request. If you want to limit the number of items to be fetched, you can use the pageSize property. For example, if you want to fetch 50 items per request, you can set pageSize to 50 like this:

useExport({  
 pageSize: 50,  
});

useExport({  
 pageSize: 50,  
});

(Source: refine.dev docs (https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/)) However, please note that useExport will export all the data by default. If you want to limit the total number of items to be exported, you can use the maxItemCount property. For example, if you want to export only 100 items, you can set maxItemCount to 100 like this:

useExport({  
 maxItemCount: 100,  
});

useExport({  
 maxItemCount: 100,  
});

(Source: refine.dev docs (https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/)) If your useExport hook keeps fetching data even though it has passed the page limit, it might be because you haven't set the maxItemCount property. Please check your code and make sure you have set the maxItemCount property correctly. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

how do i get the maxItemCount from useTable @kapa.ai

kapa.ai•10mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The useTable hook in refine does not directly provide a maxItemCount property. The useTable hook is used to fetch and process data with features compatible with the Ant Design Table Component or MUI X DataGrid Component. It provides features like sorting, filtering, and pagination out of the box. If you want to limit the number of items fetched by useTable, you can use the queryOptions property. For example, you can set the retry option to limit the number of retry attempts when fetching data:

useTable({  
 queryOptions: {  
 retry: 3,  
 },  
});

useTable({  
 queryOptions: {  
 retry: 3,  
 },  
});

(Source: refine.dev docs (https://refine.dev/docs/api-reference/antd/hooks/table/useTable/)) However, this does not limit the total number of items fetched. If you want to limit the total number of items, you might need to implement this functionality in your own code, for example by using a state variable to keep track of the number of items fetched and stopping the fetch when the limit is reached. For more information on how to use the useTable hook, you can refer to the refine.dev documentation (https://refine.dev/docs/api-reference/antd/hooks/table/useTable/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how do i use useExport without pagination

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The useExport hook in refine fetches data in batches, and by default, it fetches 20 items per request. If you want to fetch all data at once, you can set the pageSize property to a large number. For example:

useExport({{  
 pageSize: 10000,  
}});

useExport({{  
 pageSize: 10000,  
}});

(Source: refine.dev docs (https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/)) This will fetch 10000 items per request, effectively disabling pagination if you have less than 10000 items. Please note that setting a large pageSize might cause performance issues if you have a large amount of data. For more information on how to use the useExport hook, you can refer to the refine.dev documentation (https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai what makes the useExport stops fetching

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The useExport hook in refine stops fetching data when it has fetched all the data from your resource. By default, it fetches data in batches of 20 items per request. If you want to limit the total number of items to be exported, you can use the maxItemCount property. For example, if you want to export only 100 items, you can set maxItemCount to 100 like this:

useExport({  
 maxItemCount: 100,  
});

useExport({  
 maxItemCount: 100,  
});

(Source: refine.dev docs (https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/)) Setting the maxItemCount property will make useExport stop fetching data after it has fetched the specified number of items. For more information on how to use the useExport hook, you can refer to the refine.dev documentation (https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
