如何在asp.net中创建图库。

问题描述

我想创建艺术画廊。我正在使用datalist在gallery中显示艺术图像。它正在工作。现在，我想在单击图像时显示该艺术细节。但点击该图片后没有任何事情发生。请帮忙。

这是我的代码：

gallery.aspx：

I want to create art gallery. And I am using datalist to display images of arts in gallery.And it working. Now I want to display that art details when I click on Image. But nothing is happening after clicking on that image. Please help.
Here is my code:
gallery.aspx:

<asp:UpdatePanel ID="up1" runat="server">
        <ContentTemplate>
    <asp:DataList ID="DataList1" runat="server" RepeatDirection="Horizontal" RepeatColumns="4" OnItemCommand="DataList1_ItemCommand" DataKeyField="artsId"  >
        <ItemTemplate>
            <table>
                <tr>
                    <td>
                        <asp:Label ID="Label1" runat="server" Text='<%# Eval("artsId") %>' Visible="false"></asp:Label>
                    </td>
                    <td>
                        <asp:ImageButton ID="ImageButton1" runat="server" Text='<%# Eval("mainImage") %>' Height="200px" Width="200px" CommandName="ImageButton1" ImageUrl='<%# Eval("mainImage") %>'   />
                    </td>
                </tr>
            </table>
             <br />
       </ItemTemplate>
</asp:DataList>
            </ContentTemplate>
        </asp:UpdatePanel>

和我的C＃代码是：

and my C# code is:

SqlConnection con = new SqlConnection("Data Source=SNEHAL-PC\\SNEHAL1;Initial Catalog=artsondeals;Integrated Security=True");

  protected void Page_Load(object sender, EventArgs e)
  {
      if (!IsPostBack)
      {
          binddata();
      }

  }
  protected void binddata()
  {
      DataSet ds = new DataSet();
      DataTable dt = new DataTable();
      con.Open();
      string cmdr = "select arts.artsId,artdetails.mainImage from artdetails INNER JOIN arts ON artdetails.artsId=arts.artsId";
      SqlCommand cmd = new SqlCommand(cmdr, con);
      SqlDataAdapter da = new SqlDataAdapter(cmd);
      da.Fill(dt);
      DataList1.DataSource = dt;
      DataList1.DataBind();
  }

  protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
  {
      DataSet ds = new DataSet();
      DataTable dt = new DataTable();
      String str = "select artdetails.artDescription,arts.Name from artdetails INNER JOIN arts ON artdetails.artsId=arts.artsId";
      SqlDataAdapter ad = new SqlDataAdapter(str, con);
      ad.Fill(dt);
      GridView gd = new GridView();
      gd.DataSource = dt;
      gd.DataBind();
  }
