<asp:GridView ID="GV" runat="server" AutoGenerateColumns ="false" >

                        <Columns >
                            <asp:BoundField HeaderText ="ID" DataField ="id"/>
                            <asp:TemplateField HeaderText ="IMAGE">
                                <ItemTemplate>

                                    <asp:Image ID="Img" runat="server" ImageUrl="image" Width="50" Height="50"/> <br />
                                    <asp:Button ID="BtnAdd" runat="server" Text="Add To Cart"  CommandName="add" CommandArgument ='<%#Eval("id") %>' />

                                </ItemTemplate>
                            </asp:TemplateField>

                        </Columns>
                    </asp:GridView>
    </div>

在业务逻辑中，我给出了存储过程的名称，sp是

创建proc procname
首先开始
从表名中选择ID，图像
结束

id是图像的ID，而image是图像的路径.我想使用此路径绑定文件夹中的所有图像.
我如何在page_load事件中绑定我写的

in the business logic i give the storedprocedure name, the sp is

create proc procname
as begin
select id, image from tablename
end

id is id of the image, and image is path of the image. i want to bind all of the images from folder using this path.
how can i bind in the page_load event i write

protected void Page_Load(object sender, EventArgs e)
    {
        DataSet ds = new DataSet();
        ds = BusinessLogic.DisplayImage();
        GV.DataSource = ds;
        GV.DataBind();

    }

请任何人帮助我.

谢谢.

推荐答案

首先，
更改此行:
GV.DataSource = ds;

到

GV.DataSource = ds.Tables[0];

之后，您需要将datagrid中的ImageURL字段映射到数据表中的image字段，以便可以从此处进行选择.

看看此 [此 [^ ].

Firstly,
Change this line:
GV.DataSource = ds;

to

GV.DataSource = ds.Tables[0];

After this, you need to map the ImageURL field in datagrid to the image field in your datatable such that it can be picked from there.

Have a look at this[^] and this[^].

看看下面的URL.
