在单独的GridViews中显示DataTable数据C＃Asp.Net

Question

I have an aspx page with GridViews. I am using the gridview to act like a questionnaire. In a GridView, there are 4 Columns(Name, Company, Question, Answer) and 5 rows with textbox. There is a TextBox on the header where you type your name, So there are a total of 6 TextBox. After saving, the table looks like this:

name1 | company1 | question1 | answer1
name1 | company1 | question2 | answer2
name1 | company1 | question3 | answer3
name1 | company1 | question4 | answer4
name1 | company1 | question5 | answer5

name2 | company1 | question1 | answer1
name2 | company1 | question2 | answer2
name2 | company1 | question3 | answer3
name2 | company1 | question4 | answer4
name2 | company1 | question5 | answer5

and so on. Now my problem is, I don't know how to display them on separate gridviews after saving in Database. Say I want to display all records from company1, name1 's records should be displayed in a gridview and name2 's records should be displayed in a separate gridview. I need this for my Search Function. How can I do this?

Please look at this..

DataView dv = datatablename.DefaultView;
//get unique companies
DataTable distinctcompanynames = dv.ToTable(true,"companycolumnname");

foreach (DataRow dr in distinctgrouptype.Rows)
    {

        dv.RowFilter = "itemgrouptype='"+dr[0].ToString()+"'";
        //get different DataViews
        DataView singltable = dv.ToTable().DefaultView;  
        //here you can bind          
    }
