在会话状态下为购物车存储数据 [英] Storing Data in Session State for a Shopping Cart

问题描述

尝试将我存储的内容添加到购物车中的会话
中，然后将其转移到另一个页面，以获取GridView来显示我添加到购物车会话中的所有项目。将其存储为对象会话。
-AddToCart获取该行的详细信息并存储在会话中，然后获取该会话对象，并将其显示在另一页的网格视图中。

trying to take what I have stored adding something to a cart into a session then transferring it to another page to get a GridView to show up of all the items that I have added onto the Cart session. Storing it as an Object Session. -AddToCart takes that rows details and stores in A Session then takes that session object and displays it on a Grid view on another page.

从它：

 protected void GridViewDisplay_RowCommand(object sender,
 GridViewCommandEventArgs e)
 {
 if (e.CommandName == "AddToCart")
 {
 object[] values;
        DataTable orderTable;
        // Retrieve the row index stored in the 
        // CommandArgument property.
        int index = Convert.ToInt32(e.CommandArgument);

        // Retrieve the row that contains the button 
        // from the Rows collection.
        GridViewRow row = GridViewDisplay.Rows[index];
        values = new Object[GridViewDisplay.Rows[0].Cells.Count];
        for (int i = 0; i < GridViewDisplay.Rows[0].Cells.Count; i++)
        {
            values[i] = GridViewDisplay.Rows[0].Cells[i].Text;
        }

       orderTable = (DataTable)Session["OrderLine"];
       orderTable.Rows.Add(values);
       Session["OrderLine"] = orderTable;


    }

}

然后现在我尝试将其存储在会话中，以便可以在另一页的网格视图中显示它。

Then Now I am trying to take that and store it in a Session so I can display it on a grid view on another page.

推荐答案

更正了代码中的问题。

protected void GridViewDisplay_RowCommand(object sender,
 GridViewCommandEventArgs e)
 {
 if (e.CommandName == "AddToCart")
 {
 object[] values;
        DataTable orderTable;
        // Retrieve the row index stored in the 
        // CommandArgument property.
        int index = Convert.ToInt32(e.CommandArgument);

        // Retrieve the row that contains the button 
        // from the Rows collection.
        GridViewRow row = GridViewDisplay.Rows[index];
        values = new Object[GridViewDisplay.Rows[0].Cells.Count];
        for (int i = 0; i < GridViewDisplay.Rows[0].Cells.Count; i++)
        {
            values[i] = row.Cells[i].Text;
        }

       orderTable = (DataTable)Session["OrderLine"];
       orderTable.Rows.Add(values);
       Session["OrderLine"] = orderTable;


    }

}
