married dating app - Updating database using datagridview in vb net
I have designed this application with Sql Command Builder because I have some questions about using Sql Command Builder.
Builder will automatically generate insert, update, and delete command, provided that you select a primary key in your select query.
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.
The application uses an async calling mechanism to make database calls.
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.
Delegates are the best practices to design the async architectures because most things are handled internally by CLR and you do not have to bother much about them. Fill(temp Data Set); total Records = temp Data Set.
