How to check if a Element exist on the diagram

[Mithal]

Hi.

How can i check if an Element with Name "CustomerName" already exist on the diagram

I tried newDiagram.DiagramObjects.GetByName("CustomerName");

and it throws an exception.

Thanks in advance.

This is the expected behaviour if the collection does not contain "CustomerName"

Mithal,

I don't ever use Collection.GetByName as it doesn't work on all collections, and the results are random when there are multiple elements with the same name.
You better do a foreach and check the elements yourself. (or use an sqlQuery if performance is an issue)

Hi, i am using this code

EA.Element textElement = (EA.Element)parentPackage.Elements.GetByName("CustomerName");

Seems to work.

Please advise if ishould not be doing this.  I appreciate you guys response to my query.

Mithal,

What happens if you have two (or more) elements with the name "CustomerName" in your package?
Which one will be returned? -> result is unpredictable.

Thats good point.  What i will do is give the text Element a Name like zzzSYSPROCompanyName, something not very auvious.

but i will use a loop so i update the first occurence.

Thanks for your Help.
