AutoCAD C# API Switch drawing event

[Anonymous]

Hello Guys,

 I am working on an application, where based on the template I am fetching data from database.

Now if the user open multiple drawings then if the user click on the tabs to swtich between templates how do it trigger an event to fetch data relevant to the current open drawing.

Thanks.

Hi

You should have a look at the DocumentCollection events: DocuementActivated, DocumentToBeActivated, DocumentToBeDeactivated.

Dear Experts,

AdvanceSteel runs over Autocad. And Advance Steel dont have Document Collections (DocuementCollection) object.

When i call the Autocads DocuementCollection that dont load all features (Even the document is prepared with Advance Steel on Autocad and the file is dwg) If i open the same file with manual open then i get everything there

Why
