Hi,

If you are using the Rows connection style, the OriginIndex and DestinationIndex properties of DiagramLink let you find out which table rows are connected by a link. If you have an AnchorPattern set for a table, use the OriginAnchor and DestinationAnchor to find out the related anchor points.

Hi,

I have added the following event handler to the Entities sample and the values seem ok.

private void diagram_LinkDoubleClicked(object sender, MindFusion.Diagramming.LinkEventArgs e)
{
	MessageBox.Show(
		"origin row: " + e.Link.OriginIndex.ToString() + "\n" +
		"origin anchor: " + e.Link.OriginAnchor.ToString() + "\n" +
		"dest row: " + e.Link.DestinationIndex.ToString() + "\n" +
		"dest anchor: " + e.Link.DestinationAnchor.ToString() + "\n");
}
 

Have you changed anything in the sample source code? The values of these properties might not be set yet when some events are raised, e.g. LinkCreating or InitializeLink; are you accessing these properties from any of these events' handlers?

Stoyan,

I tried to change the sample code to support more than 1 output, but I can't seem to get it right.

If you add the following code to the bottom of the addBtn_Click(...) function in AddEntityForm.cs, you'll have essentially the same code as I:

          for (int i = 0; i < _input.Length; i++)
           {
               _input[i] = "in" + i;
               _output[i] = "out" + i;
           }

As you can see this populates the input and output string arrays (without any user input) and causes the app to draw a table with 3 inputs and 3 outputs.  Everything looks good -  the text, the images, the anchors, etc.  But the output index is 1 for all 3 outputs.

Am I missing something simple? Perhaps the way the table is instantiated?  Thanks for any help - this is driving me crazy!

Stoyan,

Yes, that seems to have solved the problem.  Thanks for your help.
