Asp objectdatasource onupdating age difference dating older woman younger man
The reason I want to do this is I have multiple Form Views on the same page and need to have multiple update buttons.Below is my code: Form View: Each Form View will have it's own event for handling updates so the Command Name being the same for different Form Views should not be a problem.Sql Data Source 命令逻辑由 4 个属性提供：Select Command、Insert Command、Update Command、Delete Command，它们都接收一个字符串（SQL 语句或存储过程名称）；与之相应的 Select Command Type、Insert Command Type、Update Command Type、Delete Command Type 也要设置为 Text 或 Stored Procedure （Text 是默认值）。 下面是一个完整的 Sql Data Source ，它定义了从 Employees 表中读取记录的 SELECT 命令： 创建完数据源后，我们可以在设计时绑定控件，而不必在 Page. 严格并发检查 上面的示例更新使用 ID 匹配记录，这样的做法问题在于更新命令会不加选择的更新所有字段，带来的后果是可能会消除其他用户的更新，如果他们的更新介于你请求的页面和更新的页面之间。 第二步是告诉 Sql Data Source 如何命名保持原始值的参数。默认情况下，原始值被赋予和变化了的值相同的参数名称。事实上，它们覆盖了原始参数值。为了避免这一行为，你需要设置 Sql Data Source.
I can change the Grid View to display the Supplier Name and Category Name instead of the ID's by replacing the default .Below are the first four parts of my LINQ to SQL series: control that is shipping as part of ASP. All of the business rules and business validation logic will be implemented in our data model tier - and within the UI tier or in any of the UI pages.This will ensure that: 1) a consistent set of business rules are used everywhere within the application, 2) we write less code and don't repeat ourselves, and 3) we can easily modify/adapt our business rules at a later date and not have to update them in dozens of different places across our application.I don't need to add any methods, map any parameters, or write any code for the to handle both these querying and updating scenarios - it can work against the LINQ to SQL data model we point it against and do these operations automatically.When updates are made, the LINQ to SQL ORM will automatically ensure that all business rules and validation logic we've added (as partial methods) to the LINQ to SQL data model pass before persisting anything to the database.
