Question

Please help me with the code to create Dynamic TextBox in ASP.NET and store data to SQL Server using button click. Every time a user enters x number of textbox inside the Textbox field and click on the button,it will generate the stated x numbers of row with three individual Textbox and another button will save the value to database.

Example: x = 4

[ TextBox1 ] [TextBox2] [TextBox3] |       |New Row|

[ TextBox4 ] [TextBox5] [TextBox6]        |New Row|

[ TextBox7 ] [TextBox6] [TextBox9]       |New Row|

[ TextBox10 ] [TextBox11] [TextBox12] |New Row|

|Save|
