Gridview rowupdating in asp

The visitors to a web site can typically be divided into two groups: the users and the administrators.

In data driven web sites, users are normally allowed to view data and administrators are allowed to add, edit or delete data.

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.

Page Private con As New Sql Connection("Data Source=.; Initial Catalog=pubs; User ID=sa; Password=*****") Protected Sub Page_Load(By Val sender As Object, By Val e As System. Load If Not Is Post Back Then load Stores() End If End Sub Protected Sub load Stores() con.

Data Bind() Dim columncount As Integer = grid View.

Please help me with writing a Row Updating function in C#, I don't know how to grab the current field's value and also get the old value for one of keys (which is Project Name for editing) of the selected row. the idea wa to don't allow binding the grid view after a post back.

Open() Dim cmd As New Sql Command("insert into stores(stor_id,stor_name,stor_address,city,state,zip) values('" instorid.

To String("update stores set stor_name='" stor_name.

Edit Index = -1 load Stores() End Sub Protected Sub grid View_Row Deleting(By Val sender As Object, By Val e As Grid View Delete Event Args) Dim stor_id As String = grid View.

Sql Client; public partial class _Default : System.

Open() Dim cmd As New Sql Command("Select * from stores", con) Dim da As New Sql Data Adapter(cmd) Dim ds As New Data Set() da.
