Uipath Apps: i want to calculate Sum of on entity Column

i want to display sum of “Amount” column

i don’t want to use any studio, give me any alternate way to get sum directly

you can get the sume like this in label

CDBL(MainPage.EditGrid.DataSource.data.Sum(Function(item) item.Age.Value)).ToString

Here editgrid is the grid in which I have the entity Age is the column Name which I want to sum

Here is the control
