Put in Breakpoints and it is getting to the Row Updating but will not update.
来实现双向通讯的绑定 2.因为没有添加的功能，所以用了asp: Command Field来实现编辑、删除等按钮的功能。 3.排序功能上只要在ods上设定Sort Parameter Name，它的值就是Select Method中关于排序的参数的名称，然后设定Grid View的Allow Sorting为true就ok了。排序按钮上依然用到Grid View内置的Command Name——Sort，然后Command Argument设为要排序的字段名，至于排序的方向由Object Data Source负责，省心多了。 cs代码 说明： 1.
Ideally we would need to set up the Selected Value property, which is read-only and contains the primary key of the selected row ("PKSEQ").
Sorry for the mistakes, here's again the explanation on the behavior: - If the session variable is present then the Details View will show that record and the Grid View will show the record list normally, with no selected record.
One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.
Helps make sure that your firewall rules are working as intended.
Selected Value takes priority over the Session variable).
NET Framework 3.5 release, and which enables you to easily model relational databases using . You can use LINQ expressions to query the database with them, as well as update/insert/delete data. The simple data editing web application I'll walkthrough building in this tutorial is a basic data entry/manipulation front-end for products within a database: The application will support the following end-user features: The web application will be implemented with a clean object-oriented data model built using the LINQ to SQL ORM.
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.
The approach demonstrated in issue ID: Q132070 - hide edit button for some rows is not based on the datasource type in any way. Have now managed to get this working with your help.
However I've attached sample project that demonstrates this approach and uses Object Data Source. One further point though, the borders around the cells which contain the hidden command controls are also removed.
Over the last few weeks I've been writing a series of blog posts that cover LINQ to SQL.
