Hey ,
you can get the values through many ways depending on your cell type
TextBox or Label as Template Field or A Bounded Field ,

<br />
<br />
string a =GridView1.Rows[0].Cells[0].Text ;//if it bounded Field<br />
//--------------------------------------------------------------<br />
string b =(GridView1.Rows[0].Cells[0].Controls[1] as Label).Text ; //if it template field with only one label(only one control)<br />
//--------------------------------------------------------------<br />
<br />
string c=(GridView1.Rows[0].Cells[0].Controls[1] as TextBox).Text ;//if its template field with only one TextBox(only one control)<br />
<br />
