In this demo, I presumed that you already have a basic background on how to create a simple database table. Thanks that cmd do not work fine string id = Grid View1.

In this example, this time I used my own database called Sample DB which has Customers Table and basically contains the following field columns: As you have noticed in STEP 2, we have added six Text Box and a Button in the web form in order for us to type the information there and Insert them to the database.

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.

We first of all create a Stored Procedure that gets the Id of an employee as a parameter from the Grid View on whichever row the user clicked. In this event, first we get the datakey value that is the id of an employee of whichever row the user clicked and that id is passed as a parameter to the Stored Procedure. According to the above, in these three operations we use three events of the Grid View for each operation.

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.

Now we define a method for opening a connection with the relation database and returns a SQL connection object depending on the connection string that is passed as a parameter of the Sql Connection class constructor.

Contol[0])Text; it werk just Fine any comment and thx for the code Instead of adding a Customer ID to your table and later pulling the text to get the ID number, a more reliable way to do it is to add a Data Key Names field to the grid example in the page: You can then access this information at any time with the following in code: Grid View1. Row Index]["id"]); You can do this with any field, but I've found customers get confused when they see the ID field and kept asking me why it was there, this also eliminates any issues if you change the display order of your table later (maybe add an edit/update/cancel control) Hey...great article ;)But I got a problem... So here I go with my example:protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) and the debugger says: Exception Details: System.

Nor does it represent the opinion of my dog, because I don’t have one. I have a project that I coppied the above code into. Data Keys[Row Index]["Customer ID"]in the Update event it would be something like:int Customer ID = Convert. Format Exception: Input string was not in a correct format.

If you go with the flow, you probably won't get stuck, but the moment you try to go against the grain you end up with a hand full of thorns.

Most of the data controls have events ending in ing and ed e.g. In most of the event handlers of the ing events it is easy to get the values from the event args.

Database Table Structure We are using an "EMPLOYEE" table so the "EMPLOYEE" table design is: Design of Grid View We design a Grid View with which we can perform update and delete operations.
