When I load the page this list should populate. All the details of the video clip populates, but no image is displayed. I store the images and videos in a folder, and the path of the images in a sql database. How do populate the image in the imagebutton? This is what Ive done:<asp:ListView runat="server" ID="lvlist" > <LayoutTemplate> <div id="itemPlaceholder" runat="server" /> </LayoutTemplate> <ItemTemplate> <br /> <div style="height:100px;"> <a href="PlayVideo.aspx?vid=<%# DataBinder.Eval(Container.DataItem, "ID") %>"> <asp:ImageButton id="imgVidThumbnail" runat="server" AlternateText="Watch" ImageAlign="left" Width="150" Height="120px" style="margin-bottom:10px; margin-left: 32px; margin-right:15px;" ImageUrl ='<%= ResolveClientUrl(Eval("ThumbPath"))%>' CommandArgument='<%= ResolveClientUrl(Eval("ThumbPath"))%>'/> </a> <asp:Label ID="Label4" runat="server" Text="Title: " CssClass="ltrTitle" Width="100px" ></asp:Label> <asp:Label ID="ltrTitle" runat="server" Text='<%#Eval("FileTitle") %>' CssClass="ltrTitle" Width="300px" ></asp:Label> <br /> <asp:Label ID="Label2" runat="server" Text="Date Uploaded: " CssClass="ltrTitle" Width="100px" ></asp:Label> <asp:Label ID="ltrDateUploaded" runat="server" Text='<%#Eval("DateUploaded") %>' CssClass="ltrTitle" Width="200px" ></asp:Label> <br /> <asp:Label ID="Label3" runat="server" Text="Description: " CssClass="ltrTitle" Width="120px" ></asp:Label> <div id="div" style="overflow-x:auto; overflow-y:auto; width:75%; max-width:75%; height:55px; max-height:55px; word-break:break-all; background-color:ghostwhite;" runat="server"> <asp:Label ID="ltrDescription" runat="server" Text='<%#Eval("Description") %>' CssClass="ltrTitle" Width="75%" ></asp:Label> </div> </div> <br /> <br /> </ItemTemplate> </asp:ListView>private void BindList() { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["RoadHogzConnectionString"].ConnectionString); con.Open(); SqlCommand cmd = new SqlCommand("Select * from VideoInfo", con); cmd.ExecuteNonQuery(); SqlDataAdapter adp = new SqlDataAdapter(cmd); DataSet ds = new DataSet(); adp.Fill(ds, "Video"); Session["videos"] = ds; lvlist.DataSource = GetVideoList("Select * FROM VideoInfo"); lvlist.DataBind(); }The path will change from month to month.. the only part that will stay the same is uploads and the last folder: the folder path will be like \uploads\Year\Month\thumb - month and year will change every month and every year.....EDIT:In my view source on the browser it gives it gives me a different path: This line is used here: <img runat="server" src=''<%= ResolveClientUrl(Eval("ThumbPath"))%>'' /><a href="PlayVideo.aspx?vid=1038"> <input type="image" name="ctl00$MainContent$lvlist$ctrl1$imgVidThumbnail" id="MainContent_lvlist_imgVidThumbnail_1" src="<%=%20ResolveClientUrl(Eval("ThumbPath"))%>" alt="Watch" align="left" style="height:120px;width:150px;margin-bottom:10px; margin-left: 32px; margin-right:15px;" /> </a>This line : <img runat="server" ImageUrl=''<%#Eval("ThumbPath") %>'' /> gives me the correct path which is stored in db.... 解决方案 MainContentlvlistctrl1 这篇关于使用数据库中的路径填充列表视图图像的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
