how to Add a static data view row below the data grid
I want to add a data view below the table to show the statics sum field total value. how to do?
You have two options here as far as I can think of:
If you click on the sum column you can use select an aggregate function and set this to sum. This will add a row at the bottom that shows the total of the sums.
Create a non persistent helper entity which you create when opening the page. Here you set an attribute total sum, which you calculate when opening the page. Then this object will be the page parameter and you can show the total sum attribute.
