Find a existing box

Hi,

I create a flow chart from data base with this commands:

MindFusion.FlowChartX.Commands.AddItemCmd cmd =
new MindFusion.FlowChartX.Commands.AddItemCmd(Child);

and if I have all nodes:
cmd.Execute();

during create:
if I take a new node from data base I have to check if the node already exists, because I otherwise have doubled nodes. Where and how can I check which nodes exists already

thx for support

Hi,

Better use a

flowchart.Add(Child)

method call instead of creating a command. 'Add' will check whether the node already exists in the diagram, and if it does not, an AddItem command will be created and executed.

Anyway if you need to know whether a box exists in the diagram, you could use an

if (flowchart.Boxes.Contains(box))
  ....

statement to determine that.

I hope that helps.

Oh, and it seems that was a FlowChart.NET related question again. Please post your next questions in the FlowChart.NET board (this one is for the ActiveX version of the control).

Thanks!
