我有以下datalist:
<asp:DataList ID="dlMovieImages" runat="server" RepeatDirection="Horizontal" RepeatColumns="6"
Width="100%">
<ItemTemplate >
<div class="creamebox w49" id="inDiv" runat="server">
<table width="95%" border="0" align="center" cellpadding="3" cellspacing="2" style="padding-top: 10px">
<tr>
<td colspan="2" align="left" valign="top">
<asp:Label ID="lblMovieName" runat="server" CssClass="NormalTextBig" Visible="false">MovieName</asp:Label> </td>
</tr>
<tr>
<td align="left" colspan="2" valign="top">
<asp:Image ID="imgSmall" runat="server" width="150" Height="200" Visible="false"/>
</td>
</tr>
<tr>
<td colspan="2" align="left" valign="top">
<asp:FileUpload ID="FUImage" runat="server" CssClass="NormalText" Visible="false"/>
<asp:LinkButton ID="lnkUpload" runat="server" CssClass="JustLinks" CommandName="Upload" CommandArgument='<%# Eval("MovieID") %>' Visible="false">Upload</asp:LinkButton>
</td>
</tr>
</table>
</div>
</ItemTemplate>
</asp:DataList>
使用以下代码绑定它:
If e.Item.ItemType = ListItemType.AlternatingItem Or e.Item.ItemType = ListItemType.Item Then
If rbMovies.SelectedValue = "0" Then
flag = True
If System.IO.File.Exists(Server.MapPath("~/MoviePoster/" & e.Item.DataItem("movieid") & "_L.jpg")) And System.IO.File.Exists(Server.MapPath("~/MoviePoster/" & e.Item.DataItem("movieid") & "_S.jpg")) Then
CType(e.Item.FindControl("lblMovieName"), Label).Text = e.Item.DataItem("movieid") & ". " & e.Item.DataItem("moviename")
CType(e.Item.FindControl("imgSmall"), System.Web.UI.WebControls.Image).ImageUrl = "~/MoviePoster/" & e.Item.DataItem("movieid") & "_S.jpg"
Else
TotalnoImage += 1
CType(e.Item.FindControl("lblMovieName"), Label).Text = e.Item.DataItem("movieid") & ". " & e.Item.DataItem("moviename")
CType(e.Item.FindControl("imgSmall"), System.Web.UI.WebControls.Image).ImageUrl = "~/MoviePoster/" & "no_image_S.jpg"
End If
End If
Dim divControl As HtmlGenericControl = TryCast(e.Item.FindControl("inDiv"), HtmlGenericControl)
If rbMovies.SelectedValue = "1" Then
If System.IO.File.Exists(Server.MapPath("~/MoviePoster/" & e.Item.DataItem("movieid") & "_L.jpg")) And System.IO.File.Exists(Server.MapPath("~/MoviePoster/" & e.Item.DataItem("movieid") & "_S.jpg")) Then
divControl.Visible = False
Else
divControl.Visible = True
flag = True
TotalnoImage += 1
CType(e.Item.FindControl("lblMovieName"), Label).Text = e.Item.DataItem("movieid") & ". " & e.Item.DataItem("moviename")
CType(e.Item.FindControl("imgSmall"), System.Web.UI.WebControls.Image).ImageUrl = "~/MoviePoster/" & "no_image_S.jpg"
End If
End If
If flag = True Then
CType(e.Item.FindControl("imgSmall"), System.Web.UI.WebControls.Image).Visible = True
CType(e.Item.FindControl("lblMovieName"), Label).Visible = True
CType(e.Item.FindControl("FUImage"), FileUpload).Visible = True
CType(e.Item.FindControl("lnkUpload"), LinkButton).Visible = True
End If
End If
当rbMovies =“0”时,我想显示文件夹中的所有图像,当rbMovies =“1”时,只显示一个特定图像,即“noimage”。
当Datalist受到约束时,它会显示如下:
其中noimage不适用它显示空白项目,如第3和第10所示。
我希望它在一行中。
请帮助我。

尝试在具有属性display:hidden
的表上添加一个css类mytable.hidden {visibility:hidden;}
还在表上添加一个runat =“server”并为其命名。 您可以在codebehind
中添加/删除cssclass
