Updating calculated gridview field
Currently this column is for display purposes only and I will not be doing anything else with the Weekly Total value.
My question is, how can I achieve this requirement in APEX.
You can find example configurations of the grid from this page: Configuring the Read-Only Grid.
If you're using an editable grid as a read-only grid, because you didn't have access to the rich-text component, then you could see a performance improvement changing that editable grid to a read-only grid.
Examfees are paid in installment in my project The idea if single record is found then it doing calculation of balance=promotionfees-totlafees and if anywhere due to mistyping is value is higher then the respectively msgbox displays error.
For single record it is working fine even when I update values in Datagridview.balance shown correctly.
Note: not all parameters are immediately available in Design Mode; some display only after enabling others.For example, after selecting Selectable, other selection-related parameters will be available.Sorts applied to the grid after every user interaction.The part that be reused is any query that provides the data for your grid.
If you stored the query in a local variable, you can place that query expression directly into the Data parameter of the grid, or into an expression rule (if you're reusing it), and update the paging info to use the grid's instead. The new grid doesn't require local variables since you can pass the data directly to the grid, and the new grid will automatically refresh on data change; you don't need to use , in which case you will need to pass your data to the grid from a local variable.

But issues is when there are multirecords:when I am doing total of all the row value in promotionfees(column) in totalfees(column) now balance also should show correctly that is happening fine.
