我有一个GridView绑定数据库中的值。 这是代码:
<asp:GridView ID="GridView1" AutoGenerateColumns="False" DataKeyNames="DataView" runat="server" OnRowCommand="GridView1_RowCommand">
<Columns>
<asp:BoundField DataField="ProductName" HeaderText="Title" />
<asp:ImageField DataImageUrlField="ProductId" DataImageUrlFormatString="getProductImage.ashx?ProductID={0}" HeaderText="Image">
</asp:ImageField>
<asp:BoundField DataField="ProductDescription" HeaderText="Description" />
<asp:BoundField DataField="ProductCost" HeaderText="Cost" />
<asp:TemplateField HeaderText="Quantity">
<ItemTemplate>
<asp:TextBox runat="server" TextMode="Number" ID="txtQuantity"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:ButtonField Text="Button" CommandName="AddToCart" />
</Columns>
</asp:GridView>
我想将包含来自txtQuantity和ProductID的值的命令参数传递给CommandName&#34; AddToCart&#34;后面的代码。 我怎么能这样做?

绑定ProductID&amp;的值。 GridView中的数量。在GridView中,给出如下:
<asp:GridView ID="GridView1" AutoGenerateColumns="False" DataKeyNames="DataView" runat="server" OnRowCommand="GridView1_RowCommand">
<Columns>
<asp:BoundField DataField="ProductName" HeaderText="Title" />
<asp:ImageField DataImageUrlField="ProductId" DataImageUrlFormatString="getProductImage.ashx?ProductID={0}" HeaderText="Image">
</asp:ImageField>
<asp:BoundField DataField="ProductDescription" HeaderText="Description" />
<asp:BoundField DataField="ProductCost" HeaderText="Cost" />
<asp:TemplateField HeaderText="Quantity">
<ItemTemplate>
<asp:TextBox runat="server" TextMode="Number" ID="txtQuantity" Text="<%# Bind("Quantity")%>"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:Button Text="Button" CommandName="AddToCart" CommandArgument="<%# Eval("Quantity") + "," + Eval("ProductID")%>" />
</Columns>
</asp:GridView>
在GridView RowCommand事件中,提供以下代码:
if(e.CommandName == "AddToCart")
{
string[] args = e.CommandArgument.ToString().Split(",");
Decimal Quantity = Convert.ToDecimal(args[0]);
int ProductID = Convert.ToInt32(args[1]);
}
