How to select values from gridview and give in textbox

Question

I need to check whether the cells of a particular column in gridview has certain values. If the cells contain values it should do some action. I have attached my code.

 

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

{

if (e.Row.RowType == DataControlRowType.DataRow)

{

if (TextBox1.Text != "")

{

if ((e.Row.Cells[3].Text == "1") && (e.Row.Cells[3].Text == "2"))

{

Label3.Visible = true;

}

}

}

}

 

It is not checking the AND condition. If i replace it by OR statement it works
