Hope for a fruitful reply....................

Enter a number into a textbox(like 5 or 10 or something like that.

Then that number of rows are inserted into the table ..."Master"( id,serial_no,password) .

Like if i enter 10 into that textbox and submit then inserted 10 number of rows into a table ...

Plz Help me ... i have to done it by asp.net using c#.

You can follow the below way:

//open your connection here
for(int i=0; i<Convert.ToInt(TextBox1.Text);i++)
{
// insert HERE
}
//close your connection here

Thanks 4 ur fruitful Reply But it gives some error when it insert more than 1 times ..................in a table.

Plz Sir, Give me a Solution... [:)]

Its a bit time consuming to read your code. But i can give you one tricks & hope it will resolve your problem.

Wrap all insert related code under loop. I mean within the loop open connection execute statement then close connection. So that for 2nd iteration connection will open again then execute & close so on.

If you can can insert multiple statement in this way then you can optimize your code later.
