Aspx gridview updating
NET 2.0 or later we can use specialized Details View and Form View controls. If you only need to show record in read-only mode, your data source control needs only Select command.In this example, I will use Sql Data Source control to bind Details View to SQl Server database. You can create these tables in your database with SQL code like this: For table Products Fill tables with some data and run the example to see how it works.
The following table summarizes these six data types format, range, accuracy, and storage size in bytes, and is taken from the Date and Time Data Types and Functions technical documentation.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.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. We are taking here the example of “Northwind” database which comes with SQL server 2005.In this gridview example we would perform operations like insert, update and delete on this table thru Gridview.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.
Now here in this tutorial, I’ll explain how to show data in gridview and then insert update delete gridview records (perform CRUD operation) in using c# as well as with example code.
This article explains how to add a pop-up control to a gridview in order to display drill-down (Master detail) information without using ajaxcontroltoolkit Modal Popup extender.
let us take an example to display Northwind database’s customer table.
Now, you can start an example again and joy in new features.
Test paging, updating, deleting and inserting a new record to see how it works.
I then hooked up this Sql Data Source control to a Grid View.
