Following I am mentioning step-by-step procedure to create database connection to the asp.net website textboxes via C#.

1: Open visual studio 2005 and from FILE select NEW-> WebSite, then from pop-menu select asp.net website (Note: Language must be C#) , then press OK.

2: Now create three textboxes from the toolbox , to remove ambiguity I am using default name for that textboxes and that should be textbox1,textbox2 & textbox3. And also drag & drop the button to the asp.net application.

3: Meanwhile, Open SQL SERVER Management studio 2005 and open adventureworks(or you can create your own database by the Sql command CREATE DATABASE database_name), but here I am using AdventureWorks database.

4: Then create table by clicking right mouse button and form three column, Name them according to your requirement , for your information only I used EID,name,Address. And click save button, then you’ll get a pop up menu where you have to enter the Table Name, for this example I used Employee.

5: Now Come Back to Visual studio Application and write the following code in the button_click event

protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection myConn = new SqlConnection();
myConn.ConnectionString = “Connection string(See Below for this — )COPY PASTE  HERE“;
myConn.Open();
string strqry = “Insert into students values (” + TextBox1.Text +
“,’” + TextBox2.Text + “‘,’” + TextBox3.Text + “‘)”;

SqlCommand myCom = new SqlCommand(strqry, myConn);
int numrow = myCom.ExecuteNonQuery();
myConn.Close();

}

Kindly note down the connectionString Syntax, to obtain this string do the following steps :
Step 1 : Go to toolbox and from data section drag & drop SqlDataSource.
Step 2: Then on left clicking the mouse on SqlDataSource , you will get configureDataSource link, Slect this.
Step 3: NewConnection String -> Provide Server Name then select or write database name , i.e. AdventureWorks.
Step 4: TestConnection and then Press OK.
Step 5 : Now you will again redirect to the page that you actually see in the step 2, but this time click + sign before the connection string and from the drop drown hierarchy you will receive the connection string.
Step 6: Just copy and paste this string to the place of connectionstring.
Now debug & run Your application and check it’s effect on the table.
If still you face any problem feel free to ask.
Hope this explanation help you to understand the basics of database connectivity.

Edited 6 Years Ago by __avd: Added [code] tags. Encase your code in: [code] and [/code] tags.

There are too many errors in the code...pz check..even the table name is employees not students ..?

Hi Nida,
Thanks for updating this article, I agree with the ambiguity regarding table name , can you please let me know about any other error you find in this article. It'll help me to improve it.

Thanks again for your reply.

artipathak make a new thread and ask your question there.............
we'll happy to help you three......:)
it is already a solved thread..........

Now when you were still in your Development machine you took your mdb file and place it in your : drive , now when you move it to your paid domain , there will be no d: drive, Just create a folder in your app and name it "DB" and paste your DB inside there and when you access it in your connection string use

~/DB/myDb.mdb

and you can see how i did it here
