刷新聚合结果在ag-grid中

Question

I have an ag-grid with rows grouped by one column and I want to show in the same line (group header) a value taken from first row in the group.

I found out that I can use aggregation for this, but I also want to dynamically update rows and group header in accordance with this.

To update aggregation and group header I tried to use gridApi.recomputeAggregates() , but this function refreshes the whole table on every call. Is it a right behavior? How can I avoid it?

Answer 1

You need to add valuePerser to your column defenition and parse the value as number.

colDef.valuePerser = 'Number(newValue)';

Check out the documentation about Change Detection .
