How to fiil GridView without using a table

Write a class to hold your values, and the pass the instance to arrylist..
I have tried, it fulfill your requirments.

class Data
{
string val1;
string val2;
string val3;
string val4;
string val5;

public string Val1
{
get { return val1; }
set { val1 = value; }
}

public string Val2
{
get { return val2; }
set { val2 = value; }
  }
public string Val3
{
get { return val3; }
set { val3 = value; }
  }
public string Val4
{
get { return val4; }
set { val4 = value; }
  }
public string Val5
{
get { return val5; }
set { val5 = value; }
}
}

//Adding values

private void btnok_Click(object sender, EventArgs e)
{
 Data dObj = new Data();
dObj.Val1 = "TextBox1Value";
dObj.Val2 = "TextBox2Value";
dObj.Val3 = "TextBox3Value";
dObj.Val4 = "TextBox4Value";
dObj.Val5 = "TextBox5Value";
ArrayList arr = new ArrayList();
arr.Add(dObj);
dataGridView1.DataSource = arr;
}


//you can add rows explicitly and bound values of Data class.
Hope it helps
