Gridview rowupdating change value
One note will be helpful for you, while describing Columns in Grid View if you are using a boundfield then create objects of the control using cells[index] in the rowupdateing event of Grid View, but if you are using controls itself like Label or textboxes etc then use Fincontrol("stringid").
Delete a Record We can delete a record from the database table by clicking on the delete button that is in the Delete column of the Grid View. the good old problem of getting the data from the row that is being currently edited within a Grid View. Accessing the "Controls": This method gets you access to the control in the Grid View, which might be useful based on what you are doing.Obviously the simplest method is to use Data Key Names on the Grid View and then you should have the data in your Grid View Update Event Args as part of e.

We define a connection in the web.config file and give a name to the connection string.
Now we access this connection string on the page so we can open a connection with the relation database. The first one accesses the connection string and the other is for the SQL connection.
You didn't ask this in your question, but you've written some smelly code here.
