(sum of two column) and view please help me.

Hi Anderson,

This can be achieved in two ways. One technique will be to use an expression column in a underlying datasource(datatable). Another way will be to use an ExpressionFields in a grid. See this forum thread that deals with a similar issue, and also refer to the sample in \Syncfusion\Essential Studio\4.4.0.49\windows\Grid.Grouping.Windows\Samples\FiltersAndExpressions\ExpressionField\ to know more about ExpressionField.

Also refer to the below forum thread for the pro and cons between grid's ExpressionFields and a computed columns in the datatable.
