Answer 1

Hi,

看起来你需要为每个image元素设置一个默认值，指向默认的占位图。

不够的部分使用占位图。

  imageList = new ObservableCollection<imageModel> {
                new imageModel() { path= @"..\Images\placeholder.png" } ,
                 new imageModel() { path= @"..\Images\placeholder.png" } ,
                     new imageModel() { path= @"http://sipi.usc.edu/database/preview/misc/4.1.01.png" } ,
                         new imageModel() { path= @"http://sipi.usc.edu/database/preview/misc/4.1.02.png" } ,
                             new imageModel() { path= @"http://sipi.usc.edu/database/preview/misc/4.1.03.png" } ,
                                 new imageModel() { path= @"http://sipi.usc.edu/database/preview/textures/1.1.12.png" } ,

            };

   <ListBox ItemsSource="{Binding imageList}">
            <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapPanel Orientation="Horizontal"/>
                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid Height="120" Width="100">
                        <Image Source="{Binding path}"/>
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

Sincerely,
