将GridView导出到数据表问题
本文关键字:数据表 问题 GridView | 更新日期: 2024-10-23 19:09:14
我正在尝试将网格视图数据传输到数据表中。然后将此数据表保存到会话。为什么输出以这种形式显示
在另一个页面中设置网格视图数据源
GridView1.DataSource = (DataTable)Session["cart"];
GridView1.DataBind();
输出
Pro Name Unit Price Quantity Total Amount
System.Web.UI.WebControls.GridViewRow
System.Web.UI.WebControls.GridViewRow
代码
foreach (GridViewRow row in GvProducts.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkRow = (row.Cells[0].FindControl("chkSel") as CheckBox);
if (chkRow.Checked)
{
string proid = row.Cells[1].Text;
string balance = row.Cells[3].Text;
string proname = row.Cells[2].Text;
string proqty = (row.Cells[5].FindControl("txtQuantity") as TextBox).Text;
string UnitPrice = row.Cells[6].Text;
DataTable tbl;
if (Session["cart"] == null)
{
tbl = new DataTable();
tbl.Columns.Add("Pro Name");
tbl.Columns.Add("Unit Price");
tbl.Columns.Add("Quantity");
tbl.Columns.Add("Total Amount");
}
else
tbl = (DataTable)Session["cart"];
DataRow row = tbl.NewRow();
row[0] = proname;
row[1] = Convert.ToDecimal(UnitPrice);
row[2] = proqty;
row[3] = Convert.ToInt32(proqty) * Convert.ToDecimal(UnitPrice);
tbl.Rows.Add(row);
Session["cart"] = tbl;
}
}
}
你的帮助与有关
@Ayman,问题在下面提到的部分。为"新行"提供相同的变量。
DataRow row = tbl.NewRow();
row[0] = proname;
row[1] = Convert.ToDecimal(UnitPrice);
row[2] = proqty;
row[3] = Convert.ToInt32(proqty) * Convert.ToDecimal(UnitPrice);
tbl.Rows.Add(row);
Session["cart"] = tbl;
更改依据,
DataRow newRow = tbl.NewRow();
newRow[0] = proname;
newRow[1] = Convert.ToDecimal(UnitPrice);
newRow[2] = proqty;
newRow[3] = Convert.ToInt32(proqty) * Convert.ToDecimal(UnitPrice);
tbl.Rows.Add(newRow);
Session["cart"] = tbl;
您已经为"GridViewRow"answers"DataRow"创建了具有相同名称的对象。
