+## How to specify connection direction to port
+
+The [ConnectionDirection](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.Port.html#Syncfusion_Blazor_Diagram_Port_ConnectionDirecction) property of a port allows users to specify the direction in which a connector should establish a connection. This can be either to the port incoming or from the port outgoing.
+
+The following code example how to set connection direction to port.

 ## How to get InEdges and OutEdges of ports
 
 [InEdges](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.Port.html#Syncfusion_Blazor_Diagram_Port_InEdges) is used to get the incoming connectors of the port that are connected to the port. [OutEdges](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.Port.html#Syncfusion_Blazor_Diagram_Port_OutEdges) is used to get the outgoing connectors of the port that are connected to the port.
