In the previous article , we learned how to create a simple Grid View at runtime .

Sql Client; public partial class _Default : System.

In my previous tutorials, I’d explained about how to bind data to gridview, how to get connection string, gridview inline insert update delete, difference between executereader executenonquery executescalar and other more cracking tutorials on Grid View, Asp.net, SQL Server here.

To explain further about how to bind data in gridview and perform insert update and delete operations, we need to create database table to read data and bind retrieved resultset to gridview, so simply execute following script to sql query editor to create database table and then add few records manually or download complete example code with script at the end of the page. Best practice is to use parameterized query to perform select, insert, update or delete operations instead simple sql statements.

Ok let’s move on to Code behind what we have to do when user clicks Edit, Delete, Update and Cancel When we click on Edit the On Row Editing event will be fired.

Secondly if you want to include a custom field (some button or link) in the same column it’s not possible.

If we use proper command names for the buttons like “EDIT”, “DELETE”, “UPDATE”, “CANCEL” these will also trigger the appropriate Grid View Events.

In the template field I will Place a label or some controls, So that it’s very easy to access those controls in the code behind by using Find Control method. Item Template is the content to display for the items in the Template Field.

To String() Dim stor_name As Text Box = Direct Cast(grid View.

Find Control("txtname"), Text Box) Dim stor_address As Text Box = Direct Cast(grid View.

Here is the script to create “Subject Details” table: Note: To avoid SQL Injections and security purpose, I used parameterized query in my following example code.

In this article we create a Gridview from database and add some additional operations such a add, edit and delete data in the Grid View control.
