GridView从行寻找到该控件：

protected void Button3_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow gr in GridView1.Rows)
        {
            CheckBox chk = (CheckBox) gr.Cells[4].FindControl("chk2");//在第4列中寻找对象,并转为Checkbox
            if (chk.Checked)
            {
                gr.BackColor = System.Drawing.Color.Red;
                Response.Write(gr.Cells[1].Text);
            }
        }
    }
----------------------------------

从该控件获知该行：

    protected void chk2_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox chk = (CheckBox)sender;//把对象为Checkbox
        DataControlFieldCell dcf = (DataControlFieldCell)chk.Parent;//这个对象的父类为cell
        GridViewRow gr = (GridViewRow)dcf.Parent;//cell的父类就是row，这样就得到了该checkbox所在的该行
        if (chk.Checked)
        {
            gr.BackColor = System.Drawing.Color.Green;
        }
        else
        {
            gr.BackColor = GridView1.RowStyle.BackColor;
        }
      
    }
