Forms Data Controls :: Tricky Insert Logic For Dynamically Created Row In GridView?

I am dynamically generating the Row in GridView and saving the data in database using StringCollection. Instead of using StringCollection i want to pass the data(user entered data) to local variable , eg:

string name = txtFName; and so on. but it wont work for dynamically created rows.

So if you knw how to assign the user provided data in the local variable like above i have show.

The code for inserting the records for dynamic created rows in grid view via StringCollection is below

protected void btnSave_Click(object sender, EventArgs e)
{
int rowIndex = 0;
StringCollection sc = new StringCollection();

[Code]....
