光开关屏幕仅由计算字段组成? [英] Lightswitch screen made up of only calcuated fields?

问题描述

是否可以仅由自定义字段组成LS屏幕，而这些自定义字段以编程方式确定了字段的值(相对于基础数据表或查询的行/列)?我遇到了性能问题(使用SQL Azure)，所以没有遇到本地SQL 服务器数据库，需要缓存特定表的行，根据该缓存的数据计算结果值，然后显示此计算出的数据.与显示数据绑定控件(网格，行/列等)相比，很好奇.

Is it possible to have a LS screen made up of only custom fields where the value of the field is programatically determined (vs being a row/column of an underlying data table or query)?  I've run into perf issues (using SQL Azure) so not a local SQL Server DB and need to cache rows of a specific table, calculate resultant values based on this cached data, and then display this calculated data.  Curious how to do that vs displaying databound controls (grid, rows/column, etc).
