问题描述
我正在创建地图,在某些情况下,图钉代表事件发生的位置以及事件发生的重要日期。我想在图钉本身上显示按时间顺序排列的事件的顺序(通过工具栏属性/悬停可以为用户提供额外的数据)。
例如,我想要一个看起来像这样的地图:
...看起来像这样:
有没有办法做到这一点?
解决方法
您可以使用以下任一选项:
- 设置图钉的内容属性
- 向 MapLayer 添加文本块或标签
设置图钉内容
您可以将 Content 的 Pushpin 属性设置为要在图钉上显示的文本。
例如以下代码,显示地图上图钉的 1-base 索引:
private void button1_Click(object sender,EventArgs e)
{
var locations = new[] {
new Location(47.6424,-122.3219),new Location(47.8424,-122.1747),new Location(47.67856,-122.130994)};
for (int i = 0; i < locations.Length; i++)
{
var pushpin = new Pushpin() { Location = locations[i],Content = i + 1 };
this.userControl11.myMap.Children.Add(pushpin);
}
var thickNess = new Pushpin().Height;
this.userControl11.myMap.SetView(locations,new Thickness(thickNess / 2,thickNess,thickNess / 2,0),0);
}
文本将被剪切到气球区域,所以不要在那里使用长文本。
将 TextBlock 添加到 MapLayer
您还可以添加 MapLayer,然后添加 TextBlock
或 Label
以显示更长的文本:
private void button1_Click(object sender,-122.130994)};
var pushpinLayer = new MapLayer();
var height = new Pushpin().Height;
var width = new Pushpin().Width;
for (int i = 0; i < locations.Length; i++)
{
var pushpin = new Pushpin() { };
var txt = new System.Windows.Controls.TextBlock();
txt.Text = $"Lorem ipsum dolor sit amet {i + 1}";
txt.Background = new SolidColorBrush(Colors.White);
txt.Foreground = new SolidColorBrush(Colors.Black);
txt.Width = 100;
txt.TextWrapping = TextWrapping.WrapWithOverflow;
txt.TextAlignment = TextAlignment.Center;
txt.TextWrapping = TextWrapping.Wrap;
txt.Padding = new Thickness(2);
pushpinLayer.AddChild(pushpin,locations[i]);
pushpinLayer.AddChild(txt,locations[i],new System.Windows.Point(-txt.Width / 2,-height));
}
this.userControl11.myMap.Children.Add(pushpinLayer);
this.userControl11.myMap.SetView(locations,new Thickness(width / 2,height + 1,width / 2,0);
}

var map = new Microsoft.Maps.Map(document.getElementById('myMap'),{
supportedMapTypes: [Microsoft.Maps.MapTypeId.road,Microsoft.Maps.MapTypeId.aerial],mapTypeId: Microsoft.Maps.MapTypeId.road,zoom: 12
});
var loc = new Location(47.6424,-122.3219);
var DevicePin = new Microsoft.Maps.Pushpin(loc,{ color: '#f00',text: 'W',title: '',subTitle: 'Subtitle' });
map.entities.push(DevicePin);
