info.aspx.cs:

public partial class default6 : system.web.ui.page {     datatable dt = new datatable();     protected void page_load(object sender, eventargs e)     {         dt.columns.add("name", typeof(string));         dt.rows.add(textbox1.text);         viewstate["datatable"] = dt;      }     protected void btnsumbit_click(object sender, eventargs e)     {         if (textbox1.text == " ")         {             return;         }         else if (textbox1.text != string.empty)         {             aspgrid1.datasource = (datatable)viewstate["datatable"];             aspgrid1.databind();         }     } } 

you have persist data somehow.

the standard options include database, variable stored in session state or in-page hidden fields. .net control isn't going databind it's own viewstate.

a non-standard option handle client side without post backs. if go route better served not using standard .net controls rather use straight html. require fair bit of coding.
