图像（图标）应显示在树视图左侧的数据库中。 [英] Image (icon) should display from database on the leftside of treeview.

问题描述

我创建了一个树视图，它是数据库中的类别和子类别的绑定。



我想在树视图的左侧显示一个图标（图像）。例如，在树形视图中，我有类别，例如amana工具作为父节点，路由器位作为amana工具的子节点。因此，在数据库中我有amana工具的图标以及路由器位的图标。现在，我只能在treeview中显示类别（amana工具）。但是，我需要左侧应显示相关类别的图标，然后显示类别名称（amana工具）。





注意：图标应该从数据库绑定，但它不应该是静态图标，因为我需要显示超过100个类别和数据库中存在的图标。



请帮帮我。

I have created a treeview, which is binding categories and subcategories from database.

I want to display an icon (image) on left side of the treeview. For example, in treeview I have categories such as amana tool as a parent node and the router bits as child node of amana tool. So, in database I have icon of amana tool as well as icon of router bits. Now, I am able to show categories (amana tool) only in treeview. But, I need that left side should show the icon of the related categories and then categories name(amana tool).


Note: The icon should bind from database but it should not be static icon because I need to show more than 100 categories and the icon existing in database.

Please help me out.

推荐答案

您好，

您必须将树视图项定义为单独的类。在该类中定义属性，如header，url和image source。请参阅下面的代码以了解更多信息。

将树视图项定义为类名称MenuItem。

代码：

Hi,
You have to define a tree view item as a seperate class. In that class define propertys like header, url and image source. see below code for more understand.
Define a tree view item as class name MenuItem.
Code:

MenuItem Class:
public class MenuItem
    {
        public string Header { get; set; }
        public string Url { get; set; }
        public BitmapImage ImageSource { get; set; }
        public List<menuitem> SubMenuItems { get; set; }
    }

List <menuitem> MenuItems = new List<menuitem>();
MenuItems.Add(
                    new MenuItem()
                    {
                        Header = "Display Name",
                        Url = "NavigationUrl",
                        ImageSource = new System.Windows.Media.Imaging.BitmapImage(new Uri("ur image url from database", UriKind.RelativeOrAbsolute)),
                                            });
//Bind menitems list to ur treeview 
tvLeftMenu.ItemsSource = MenuItems;

谢谢
