Class DiagramDataMapSetting

Maps the data from the data source to the diagram layout nodes.

Inheritance
System.Object
Syncfusion.Blazor.SfBaseComponent
Syncfusion.Blazor.SfBaseExtension
DiagramDataMapSetting
Namespace: Syncfusion.Blazor.Diagrams
Assembly: Syncfusion.Blazor.dll
Syntax
public class DiagramDataMapSetting : SfBaseExtension
Remarks
Based on the user-defined JSON (Local) data, the diagram is populated. This can be done only by mapping the local data to Data Source fields.
Examples
<SfDiagram> 
   <DiagramDataSource Id = "Name" ParentId="Category" DataSource="@DataSource" DataMapSettings="@Datamap"> 
       <DiagramDataMapSettings> 
           <DiagramDataMapSetting Property = "Annotations[0].Content" Field="Name"></DiagramDataMapSetting> 
       </DiagramDataMapSettings> 
   </DiagramDataSource> 
</SfDiagram>
@code{
   public class HierarchicalDetails
   {
       public string Name { get; set; }
       public string FillColor { get; set; }
       public string Category { get; set; }
   }
   List<DiagramDataMapSetting> Datamap { get; set; } = new List<DiagramDataMapSetting>()
   {
       new DiagramDataMapSetting() { Property = "Shape.TextContent", Field = "Name" }
   };
   ///Create the data source with node name and fill color values. 
   public List<object> DataSource = new List<object>()
   {
       new HierarchicalDetails(){ Name ="Diagram", Category="",FillColor="#916DAF"},
   };
}
