Request for Assistance with useDataGrid
Hello,
I hope this message finds you well. I am reaching out because I am currently facing an issue with the useDataGridhook with DataGridPro in conjunction with other hooks, and I am in need of some guidance and assistance.
To provide some context, I have implemented pagination on the server side, and in order to obtain the total row count, I have been sending a response from the resource that includes an object structured as follows:
Upon receiving this response, I have been destructuring the 'total' and 'data' properties separately, using the following code:
Subsequently, in my DataGridPro component, I have utilized the extracted data in the following manner:
While this approach has served me well so far, I have encountered a limitation with other hooks. Specifically, I am trying to utilize the useExport hook to enable exporting data from the DataGridPro component. However, despite my efforts, the useExport hook does not seem to work within this setup.
Therefore, I am seeking your guidance on alternative strategies to overcome this limitation while still being able to keep track of the total number of rows. One possibility I have considered is maintaining a separate state and creating a dedicated endpoint solely for retrieving the total count. However, this approach appears to be somewhat tedious. I would greatly appreciate it if you could suggest any alternative ideas or best practices that could help me resolve this issue more efficiently.

Hello,
Based on the information extracts provided, I can't find a direct solution to your issue with the
useDataGrid
hook and DataGridPro
component in conjunction with the useExport
hook. However, I can provide some general guidance on using the useDataGrid
hook with the DataGridPro
component.
The useDataGrid
hook is compatible with both the DataGrid
and DataGridPro
components source (https://refine.dev/docs/api-reference/mui/hooks/useDataGrid). It simplifies operations such as pagination, sorting, and filtering on the DataGrid
component through a flexible API source (https://refine.dev/blog/mui-datagrid-refine).
To handle pagination, you can set the paginationMode
, page
, onPageChange
, pageSize
, and onPageSizeChange
props that are compatible with the DataGrid
component source (https://refine.dev/docs/api-reference/mui/hooks/useDataGrid#pagination). The hook also syncs the pagination state with the URL if you enable the syncWithLocation
source (https://refine.dev/docs/api-reference/mui/hooks/useDataGrid#syncwithlocation).
For the total number of data, the useDataGrid
hook returns a rowCount
value fetched with the useList
hook source (https://refine.dev/docs/api-reference/mui/hooks/useDataGrid#rowcount).
Unfortunately, I don't have enough information about the useExport
hook to provide a confident solution to your specific issue. I recommend referring to the refine documentation and examples for more information on how to use the hooks together.
If you still face issues, consider reaching out to the refine community or support channels for more assistance.

hi, what is the limitation you encounter?

@alicanerdurmaz Hello,
I am experiencing an issue with the useExport hook while using the modified data structure I received from my resource. When I press the export button, nothing appears to happen. Additionally, I am unsure how the useExport hook can correctly parse the information with this modified data structure.
Thank you for your help!
If I switch to the standard data structure that's expected from the resource, the useExport hook works as intended
ratty-blush•15mo ago
what do you mean by modified data structure? where are you modifying ?
ambitious-aqua•15mo ago
I have a resource called let's say "orders", and the useDataGrid would be using "/orders". The standard data structure would be to just send a list of all the orders, but I'm sending
and then I grab these separately by desctrucuring and implement them with DataGridPro as explained earlier.
I did it this way because I'm handling pagination server side, and without this the rowCount would just be the total number of rows being sent from the server, which would be the first 25 (if 25 page size was selected), from the _start and _end from the req.query.
so useExport is trying to parse
?
And if I refactor my server to just send a list of all the rows, useExport works correctly. So should I just track the total rows separately and keep the resource response as a list of all the rows?
ratty-blush•15mo ago
you need to give same filters to useExport too 🤔
https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/#pagesize
sorry if i could'nt understand. if you provide reproducible example i will happy to debug
actually useDataGrid and useExport uses getList method. they have only diffrence one is using export to csv, other uses datagrid features.
data fetching features are same
ambitious-aqua•15mo ago
The main issue is this modified data (getList is sending an object with data, total properties) I'm sending is not playing nicely with useExport. useExport expects getList to retrieve a list of items? I'm not sending a list of items due to how I did a workaround for useDataGrid.
Do you have any recommendations on how server side pagination should be handled in general when using useDataGrid, maybe a different approach compared to how I'm handling the total rows? Because if I don't do it this way, every time my useDataGrid fetches rows, the rowCount is just the amount of rows that are sent from the server. So if the page size is 25, the rowCount will always be 25.
Sorry if it's not entirely clear, but I was mainly looking for some advice or a different approach. The problem can be solved if i just send a list of items instead of this {data, total} object, and just track the total with some separate request.
Thank you for your help!

I believe i understand 🥹
you can send
meta
with useExport after that you can check in your dataProvider
if meta
object has isExport
field. if has, you can modify your data to array
if I understand correctly. it's a problem
we have mapData function but thats not enough. https://refine.dev/docs/api-reference/core/hooks/import-export/useExport/#handling-relational-data
I believe useExport needs transformResponse
function to manipluate data without touching the `
dataProvider
useExport taking
data` field from dataProvider.getList function

Ah I see, thank you very much for your patience and your response. As of right now, I have not created a custom dataProvider, but it's good to know that I can use a meta object this way Very cool
@alicanerdurmaz Instead of that modified data structure({data: [all items], total: totalRows} and then destructuring the dataGridProps and adding a bunch of stuff to DataGrid separately, I found that I can just add proper headers from my server when sending a response, to get the total when using server side pagination
for anyone wondering, you can set your total rows using
!!
With this approach I don't have to do a workaround to get the proper rowCount!
Thank you again @alicanerdurmaz

Thanks! Access-Control-Expose-Headers solved the issue, chrome network tool seems to have x-total-count exposed but doesnt
