Hi Kesavan,
The Visio’s shapes contain connection points by default and we do not set visibility as false for connection point for that shapes while converting the Visio shapes to the Diagram’s shapes. So only the Visio’s converted shapes are showing the connection point in our Diagram.
We have confirmed that the issue with “the connection point visibility updated wrongly while converting Visio stencil to diagram” is a defect and we have logged a defect report. The fix for this issue will be available in our volume 2 release it will be available on end of the April 2018.
However, we suggest you to use ConnectionPoint’s “Visible” property to set as false after converting the Visio’s shapes to diagram compatibility by using SymbolPalette’s “Nodes” collection property. Please refer to the below code example.
Code example:
[C#]
SymbolPalette paletteToReturn = null;
string strFileName = @"...\\...\\SOACP_Visio_Stencil.vss";
//Create an instance of VisioStencilConverter
VisioStencilConverter converter = new VisioStencilConverter(strFileName);
converter.ShowProgressDialog = true;
//Convert the stencil as SymbolPalette
paletteToReturn = converter.Convert();
///Hide the connection point by default
foreach (Node node in paletteToReturn.Nodes)
{
foreach (ConnectionPoint cp in node.Ports)
{
if (!(cp is CentralPort))
{
cp.Visible = false;
}
}
}
paletteGroupBar1.AddPalette(paletteToReturn);
Also in our diagram control, we can only set enable/disable the visibility option to hide the connection point manually. We don’t have built-in support to the connection point become visible, if we will move the connector’s endpoint to near of them like MS Visio. However, we can achieve this behavior in application level to use Diagram’s MouseMove event to enable/disable the visibility of the connection point when the Diagram.Controller’s “ActiveTool” is in “HandleMoveTool” mode. Please refer to the below code example and sample.
Code example:
[C#]
diagram1.MouseMove += diagram1_MouseMove;
void diagram1_MouseMove(object sender, MouseEventArgs e)
{
if (diagram1.Controller.ActiveTool is HandleMoveTool && diagram1.Controller.ActiveTool.InAction)
{
Node tempHit = diagram1.Controller.GetNodeAtPoint(this.diagram1.Controller.MouseLocation);
if (tempHit != null)
{
nodeHit = tempHit;
foreach (ConnectionPoint cp in nodeHit.Ports)
{
if (!(cp is CentralPort))
{
cp.Visible = true;
}
}
}
if (tempHit == null && nodeHit != null)
{
foreach (ConnectionPoint cp in nodeHit.Ports)
{
if (!(cp is CentralPort))
{
cp.Visible = false;
}
}
nodeHit = null;
}
}
}
