id and widget bindings stay intact — every widget that references the dataset re-renders with the new data.
1
Open Manage Custom Data
From the Data Query widget’s Custom Data source, click Manage next to the Dataset label.
2
Edit the dataset
Select the dataset and edit its rows in the grid, re-upload a file, or change its name.
3
Save
Widgets using this dataset pick up the changes on the next render.
If you change the columns, widgets configured against the old column names will need to be re-mapped.
API
PUT /v1/custom-data/{id} applies a partial update — send only the fields you want to change. Accepted fields are name, file_name, raw_data, columns, and file_size. When you send raw_data, Oviond recalculates row_count (and rejects payloads over 10,000 rows). To rename a dataset, send just name.
