问题描述
基本上我在下拉列表中有两个面板控件。在这些面板中还有一个下拉列表。现在我可以从dropdownlist1输入数据到数据库。但是不知道如何从面板下的那些下拉列表输入数据到数据库。
请帮帮我....
这里是我的cs代码
protected void select_ctgry（object sender，EventArgs e）
{
if（DropDownList6.SelectedValue） .ToString（）==豪华）
{
Panel1.Visible = true;
Panel2.Visible = false;
Panel3.Visible = false;
}
else if（DropDownList7.SelectedItem.ToString（）==SUV）
{
Panel1.Visible = false;
Panel2.Visible = true;
Panel3.Visible = false;
}
其他
{
Panel1.Visible = false;
Panel2.Visible = false;
Panel3.Visible = true;
}
}
protected void click_insert（object sender，EventArgs e）
{
SqlConnection con = new SqlConnection（ConfigurationManager.ConnectionStrings [carrental]。ConnectionString）;
SqlCommand cmd = new SqlCommand（）;
尝试
{
cmd.Connection = con;
cmd.CommandType = CommandType.Text;
cmd.CommandText =插入car_insert（城市，loc，c_type，电子邮件，日期，时间）值（@ city，@ loc，@ c_type，@ email，@ date，@ time）;
cmd.Parameters.AddWithValue（@ city，DropDownList1.SelectedItem.Text.ToString（））;
cmd.Parameters。 AddWithValue（@ loc，DropDownList2.SelectedItem.Text.ToString（））;

cmd .Parameters.AddWithValue（@ email，TextBox2.Text.ToString（））;
cmd.Parameters.AddWithValue（@ time，DropDownList4.SelectedItem.Text.ToString（））;
con.Open（）;
cmd.ExecuteNonQuery（）;
con.Close（）;
回复.Redirect（showdata.aspx）;
}
