在数据列表中点击图片后发送ID [英] send id when image clicked in datalist

问题描述

大家好
我正在使用数据列表在imagebutton中查看数据库中的图像，并希望在单击图像时转到具有该图像ID的另一页，以从数据库中获取该图像的详细信息

数据列表的此代码

hi all
i am using datalist to view image from database in imagebutton and want when clicked to image go to another page with id of this image to get the details of this image from database

this code of datalist

asp:DataList ID="DataList1" runat="server"  RepeatColumns="3"  OnItemCommand="DataList1_ItemCommand" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Both" Width="719px"  >
        <ItemTemplate>
            <asp:ImageButton ID="ImageButton2" runat="server" ImageUrl='<%#Eval("image")%>' CommandName="selectimage" Width=100 Height=100 /><br />

我正在CS中使用此代码

i am using this code in cs

protected void DataList1_ItemCommand(object source,
        System.Web.UI.WebControls.DataListCommandEventArgs e)

    {

        if (e.CommandName == "selectimage")
        {

            int Id = int.Parse(e.CommandArgument.ToString());
            
            Response.Redirect("~/clothes3.aspx?Id=" + e.CommandArgument.ToString());

        }
    }

但单击图像时出现异常，但我没有原因

but get an exception when clicked on image but i do not the reason
