Let's first look at an example: Bool a, B, c, d; A = true; B = false; C = false; D = false; If we execute if (A or B or C or D) {}, we find that when Program When a is executed, if it is true, the following statement is executed. Therefore, it is unnecessary to judge the values of B, C, and D. Recently, some large data volumes have been compared for multiple times. Because some record blocks are compared for multiple times, these records are stored in the datatable to improve the search perf

results, few articles have mentioned this problem. Some examples on the Internet directly use spdatasource for data binding when using the Sharepoint list as the data source. This item is also added in 2007. With a spgridview control, you can directly bind it to a Sharepoint list through the list attribute. There is no problem with the display, but there is a problem in sorting and filtering. I don't know if the authors of those articles have tried to bind the Sharepoint list. I cannot use the
