DataBinding in EJ 1 ASP.NET MVC TreeMap
18 Nov 2017 / 3 minutes to read
TreeMap control supports Data Binding and it can be achieved using DataSource
property.
The DataSource
property accepts the collection values as input. For example, you can provide the list of objects as input. The following code illustrates you on how to bind a flat collection as datasource for TreeMap.
@(Html.EJ().TreeMap("treemap")
.DataSource(datasource)
.WeightValuePath("Population")
.ColorValuePath("Population")
.Render())
public class TreeMapPopulationData
{
public string Continent { get; set; }
public string Region { get; set; }
public double Growth { get; set; }
public long Population { get; set; }
public static List<TreeMapPopulationData> GetData()
{
List<TreeMapPopulationData> population = new List<TreeMapPopulationData>();
population.Add(new TreeMapPopulationData() { Continent = "Asia", Region = "Southern Asia", Growth = 1.32, Population = 1749046000});
population.Add(new TreeMapPopulationData() { Continent = "Asia", Region = "Eastern Asia", Growth = 0.57, Population = 1620807000});
population.Add(new TreeMapPopulationData() { Continent = "Asia", Region = "South-Eastern Asia", Growth = 1.20, Population = 618793000});
population.Add(new TreeMapPopulationData() { Continent = "Asia", Region = "Western Asia", Growth = 1.98, Population = 245707000});
population.Add(new TreeMapPopulationData() { Continent = "Asia", Region = "Central Asia", Growth = 1.43, Population = 64370000});
population.Add(new TreeMapPopulationData() { Continent = "Europe", Region = "Europe", Growth = 0.10, Population = 742452000});
population.Add(new TreeMapPopulationData() { Continent = "America", Region = "South America", Growth = 1.06, Population = 406740000});
population.Add(new TreeMapPopulationData() { Continent = "America", Region = "Northern America", Growth = 0.85, Population = 355361000});
population.Add(new TreeMapPopulationData() { Continent = "America", Region = "Central America", Growth = 1.40, Population = 167387000});
population.Add(new TreeMapPopulationData() { Continent = "Africa", Region = "Eastern Africa", Growth = 2.89, Population = 373202000});
population.Add(new TreeMapPopulationData() { Continent = "Africa", Region = "Western Africa", Growth = 2.78, Population = 331255000});
population.Add(new TreeMapPopulationData() { Continent = "Africa", Region = "Northern Africa", Growth = 1.70, Population = 210002000});
population.Add(new TreeMapPopulationData() { Continent = "Africa", Region = "Middle Africa", Growth = 2.79, Population = 135750000});
population.Add(new TreeMapPopulationData() { Continent = "Africa", Region = "Southern Africa", Growth = 0.91, Population = 60425000});
return population;
