Optimizing forms that comply with legislation requirements

This article provides recommendations for optimizing forms that comply with legislation requirements, and other similar entities (such as reports or spreadsheet documents).

1. Optimize templates by avoiding a large number of columns or merged cells.

You can win a fraction of a second every time a user finishes editing a cell by simplifying a template. We recommend that you use custom column width in each row instead of cell merging (the users will not notice any difference).

2. Calculate the changes on the client side. Only calculate cells that actually depend on the changed cell.

If your application makes a server call in order to update the form state when a user changes a cell value, this can impact the performance.

3. Do not update button states dynamically based on the currently selected spreadsheet document area.

Instead, make the action tied to a button available only in a specific document area. If you cannot explicitly specify the area, you can implement a user notification explaining why the action is not available.

4. If a server call is necessary, implement a single call.

This example includes two server calls, which is incorrect:


To correct this, you have to replace the two lines with a single server procedure call, which includes all of the server method calls.
