问题描述
我想在DataView中的DetailsView中动态存储一个数据，并在DetailsView中显示结果。
将数据存储到数据库表后再显示。 br />
假设，Product表的Table属性是
1. ID（Int）（自动增量）
2.特征（Varchar2（50） ））
我想将产品名称，颜色和价格存储到一列中，即功能;
Hi,
I want to store one by one data dynamically in DetailsView from DataTable and display result in DetailsView.
After Store data into database table then display.
Suppose, Table attribute of "Product" table are
1. ID (Int) (Auto Increment)
2. Features (Varchar2(50))
I want to store "Product name", "Color" and "Price" into only one column i.e, "Features";
protected void Button1_Click(object sender, EventArgs e)
{
string item1 = TextBox1.Text + "\n"; // Product Name
string item2 = TextBox2.Text + "\n"; // Color
string item3 = TextBox3.Text + "\n"; // Price
string AllItem = item1 + item2 + item3; // Suppose: AllItem= Nokia 5230\nBlack\n7500
con.Open();
cmd.Connection = con;
cmd.CommandText = "insert into product values('" + AllItem + "')";
cmd.ExecuteNonQuery();
con.Close();
}
然后我尝试将值单独存储到DataTable然后显示DetailsView：
Then I try to store value separately into DataTable Then display DetailsView:
protected void Button2_Click(object sender, EventArgs e)
{
DataTable dt = new DataTable();
con.Open();
cmd.Connection = con;
cmd.CommandText = "Select Features from Product where id=5";
dr = cmd.ExecuteReader();
if (dr.HasRows)
{
while (dr.Read())
{
string result = dr["Features"].ToString();
int ln = result.Length;
dt.Columns.Add("items");
int index = result.IndexOf("\n");
while (ln > 0)
{
string a = result.Substring(0, index);
dt.Rows.Add(a);
ln = ln - (index + 1);
result = result.Substring(index + 1, ln);
index = result.IndexOf("\n");
}
}
int len = dt.Rows.Count;
for (int i = 0; i < len; i++)
{
DetailsView1.Rows.Cells.Text = dt.Rows[1].ToString();
}
DetailsView1.DataBind();
}
}
在DataTable dt中存储值。那是
Store value in DataTable dt. That is
dt.Rows[0][0]=Nokia 5230
dt.Rows[1][0]-Black
dt.Rows[2][0]=7500
我想要将这些值存储在DetailsView的以下结构中
产品名称：诺基亚5230
颜色：黑色
价格：7500
但不能存储。
请解决我的问题。
I want to store these value in following structure in DetailsView
Product Name: Nokia 5230
Color: Black
Price: 7500
But can't be store.
Please solve my problem.
