Hello,
There is a bug in the Grid with aggregate functions
If we use this link for reference:
https://developer.mescius.com/wijmo/demos/Grid/Aggregation/Customaggregation/angular
and then change in the app.component.html sales column to:
<wj-flex-grid-column [binding]=“‘sales’” [header]=“‘Sales’” [aggregate]=“‘First’”>
and then change in the app.component.ts sales data to null:
private _getData() {
// create some random data
let countries = ‘US,Germany,UK,Japan,Italy,Greece’.split(‘,’),
products = ‘Phones,Computers,Cameras,Stereos’.split(‘,’),
data = ;
for (let i = 0; i < 200; i++) {
data.push({
id: i,
country: countries[i % countries.length],
product: products[i % products.length],
sales: null, //Math.random() * 10000,
expenses: Math.random() * 5000
});
}
return data; }
and then run the app the grid will be broken and the error will be:
“ERROR Invalid aggregate type.”
This is happening only for ‘First’ aggregate function… if we change it to ‘Last’ it will work properly
