关于Gridview_rowupdating事件出错

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int ID = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value.ToString());
string Pass = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[4].Controls[0])).Text.ToString();
string Sname = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[5].Controls[0])).Text.ToString();
string Sgender = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[6].Controls[0])).Text.ToString();
string Sbirth = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[7].Controls[0])).Text.ToString();
string Sorgin = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[8].Controls[0])).Text.ToString();
string Schoolyear = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[9].Controls[0])).Text.ToString();
string Sdepart = ((TextBox)(GridView1.Rows[e.RowIndex].Cells[10].Controls[0])).Text.ToString();
SqlConnection sqlconstr = new SqlConnection();
sqlconstr.ConnectionString = "server=localhost;database=StudentManage;Trusted_Connection=SSPI";
string Updatesql = "update Studentinfo set password=" + Pass + ",Sname=" + Sname + ",Sgender=" + Sgender + ",Sbirth=" + Sbirth + ",Sorgin=" + Sorgin + ",Schoolyear=" + Schoolyear + ",Sdepart=" + Sdepart + "where='" + ID.ToString() + "'";
SqlCommand cmd = new SqlCommand(Updatesql, sqlconstr);
sqlconstr.Open();
cmd.ExecuteNonQuery();
cmd.Dispose();
sqlconstr.Close();
GridView1.EditIndex = -1;
BindData();
}
