This demo showcases the Smart.Grid component with a built-in formula column that automatically calculates values based on other columns in the same row. The grid displays a list of products with their quantity and unit price, and dynamically computes the total cost per row using the formula =quantity * price. Key features demonstrated: Formula Column: The "Total" column uses a formula to calculate the product of Quantity × Price for each row. Editable Grid: Users can directly edit the Quantity and Price cells, and the Total updates in real time. Custom Formatting: Price and Total values are formatted as currency with two decimal places and a Euro symbol. Live Calculation: Edits made by the user immediately reflect in the calculated column without reloading.
