How do I combine two JSON file into single List and create a table? I need to put these JSON together and map it into a single table. These two JSON have same rows count.
Hello Asrul,

Hi there! Loved the tutorial! Was quick and easy to understand! Just one thing tho, I would like to have a button on there which will pass the product name onto another class (I will be doing another request with that,) any idea how? Thanks!
Hi,
We are glad that you have found it helpful.
For the fastest response to technical questions, we recommend opening a support ticket here,
www.syncfusion.com/support/directtrac/incidents/newincident
We will check on this with our team and post a response but it will take a little time.
Thanks for your question!
Please provide more details about your requirement, and it will help to understand and provide a prompt solution at the earliest.
Do you want to pass the selected row to another class?
Do you want to perform a CRUD operation in DataGrid?
@@SyncfusionInc I wish to be able to pass the product name to another function as it will be used to generate another JsON get request.
We suspect that you are trying to get cell value when tapping the grid cell. If yes, you can get the cell value from the onCellTap callback.
Refer to the following KB article: www.syncfusion.com/kb/12895/how-to-get-the-cell-value-when-tapping-the-cells-in-flutter-datatable-sfdatagrid
If we misunderstood anything, please provide more details about your requirement.
Can you show us how can we combine sfdatagrid and sfdaterange, for example we have data from firestore with a date, and when user pick a daterange, data in the table will only shows data between the date range
Hi,
Thank you for reaching out.
To fulfill your requirement, you can implement programmatic filtering by assigning the appropriate value to the corresponding Date column. You can then apply the filter programmatically using the selected range of dates in the Date range picker button. Please refer to the provided code snippet for further details.

Please refer to this KB article to load data from Firebase to Flutter DataGrid.
KB Document: www.syncfusion.com/kb/12766/how-to-load-data-from-firebase-to-flutter-datatable-sfdatagrid
Is SfDataGrid free/opensource or we have to pay it? Can u show how to styling last row in datatable where the data get from JSON? I have successfull to load data with JSON API using datatable but can not figure out how to styling las row different from other
Hello,
To customize the row cell style, adjust the required style within the Text widget loaded in the DataGridSource.pulse.ly/mrykwvktfn method. Within this method, determine if the row is the last one by using the indexOf method from the DataGridSource.pulse.ly/tjl6k2dihj property. When identifying the last row, set a custom style using the Text.pulse.ly/jrfhs5g0z3 widget and modify the last row's background color via the DataGridRowAdapter.pulse.ly/co3o6mviqd property.
Sample Link: syncfusion.pulse.ly/c31c6d8zqd
For comprehensive guidance on styling, please consult our User Guide document, where you'll find extensive details and examples on this topic, aiding in the implementation of desired styles.
