Hit a problem with an AddIn I've almost finished developing. Without going into detail, I need the AddIn to respond to any changes in datasources on layers and stand-alone tables. Basically, my AddIn needs at least one feature layer and one stand-alone table to work, so it's toolbar buttons are disabled until the criteria is met. So far I have an extension hooked into the NewDocument and OpenDocument to interrogate the documents layers and their validity, creating two arrays of valid feature layers and valid stand-alone tables. This used to be in the tool's update event but the checking process had a significant affect on performance.</SPAN><BR /><BR /><SPAN>I hope someone can advise?</SPAN><BR /><BR /><BR /><SPAN>Thank you.</SPAN></BODY></HTML> Tue, 09 Jul 2013 08:32:21 GMT https://community.esri.com/t5/arcobjects-sdk-questions/addin-help-needed-detecting-changes-in-layers/m-p/357757#M9465 AndrewClark 2013-07-09T08:32:21Z Re: ADDIN: Help needed detecting changes in layers https://community.esri.com/t5/arcobjects-sdk-questions/addin-help-needed-detecting-changes-in-layers/m-p/357758#M9466 <HTML><HEAD></HEAD><BODY><SPAN>Andrew,</SPAN><BR /><BR /><SPAN>Sounds like you want to be hooking into the </SPAN><A href="http://resources.arcgis.com/en/help/arcobjects-net/componenthelp/index.html#/IActiveViewEvents_Interface/00120000019m000000/">IActiveViewEvents</A><SPAN> Interface and capture when the map changes in someway.</SPAN><BR /><BR /><SPAN>Duncan</SPAN></BODY></HTML> Thu, 11 Jul 2013 10:10:47 GMT https://community.esri.com/t5/arcobjects-sdk-questions/addin-help-needed-detecting-changes-in-layers/m-p/357758#M9466 DuncanHornby 2013-07-11T10:10:47Z
