We can achieve the same functionality using Datakeys.

In this example, I am going to retrieve values from categories table of Northwind database. Drag a Grid View into the Web Form and assign Data Key Names property with the primary key column i.e. In the gdview_Row Editing and gdview_Row Deleting event, we have used the below code to retrieve categoryid from datakey of Grid View, int catid = int.

Sql Client; public partial class _Default : System.

Grid View正反双向排序: 效果图:点姓名各2次的排序,点其他也一样可以。 后台代码: using System; using System.

Many a times in our applications we use primary keys to get control of the particular record in the gridview.

For this situation, many developers use invisible columns (Hidden columns) in the gridview to identify that row.

Save all or press "Ctrl S" and hit "F5" to run the page, the page will look as in the following image: Click on "Edit the Grid View", it will display Textboxes in each cell as in the following image: Edit the value(s) here and click on the Update link, it will update all the data or to remove it click on the "Delete" link above the image shown.
