Question

获取gridview模板列textbox的值失败

前台图片和代码：

<Columns>
<asp:BoundField DataField="GoodsName" HeaderText="商品名称" ControlStyle-Width="200" />
<asp:BoundField DataField="GoodsTypeName" HeaderText="所属类别" ControlStyle-Width="30" />
<asp:BoundField DataField="GoodsPrice" HeaderText="商品价格" ControlStyle-Width="30" />
<asp:CommandField HeaderText="删除" ShowDeleteButton="True" ControlStyle-Width="30">
<ItemStyle Font-Underline="False" />
<ControlStyle Font-Underline="False" ForeColor="Black" />
</asp:CommandField>
<asp:TemplateField HeaderText="数量">
<ItemTemplate>
<asp:TextBox ID="GoodsCount" runat="server" Text='<%# Bind("Number") %>' Width="30" OnTextChanged="TextChanged" AutoPostBack="True"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
后台获取值：
double price = Convert.ToDouble(gvOrderInfo.Rows[i].Cells[2].Text.Trim());
double count = Convert.ToDouble((gvOrderInfo.Rows[i].FindControl("GoodsCount")).Text.Trim());
//double count = Convert.ToDouble((gvOrderInfo.Rows[i].Cells[4].Controls[0]).Text.Trim());
price获取没问题，但两个count获取部分都提示： “System.Web.UI.Control”并不包含“Text”的定义
急：求解啊，被卡住了，进行不下去了

Answer 1

改成 Convert.ToDouble((gvOrderInfo.Rows[i].FindControl("GoodsCount") as TextBox).Text.Trim());
需要强制转换的，不会自动转换的！
