We are making some customizations to the Account, Contact and Opportunity entities and the developers are finding out that the subgrids for Contacts, Accounts an Opportunities keep refreshing (or Flashing) as we called now.
I when and look for the cause and how to eliminate the flashing on the sub-grids.
Select from the Navidation Settings
Select again from the navigation Solutions or Customizations
Click on the Main Solution we are working on or select Customize the system
Select the Entity tab (Account, Contact, Opportunity)
Click on Forms
Edit the main Form for the Entity in this case Account
Click on the Contacts sub-grid on the right column
On the ribbon click Change Properties
Under Data Source Section update the Default View and select the Active Contacts replacing the view called Active Contacts Subgrid View
click on the Set button to complete the propertie changes
Save and Close
Do the same for the Recent Opportunities, change the subgrid default view to another
when all the customization are completed then Publish All Customizations
Do not forget to refresh your internet explorer and try again.
So far I seen a lot better improvement on the form with a different subgrid default view and stop with the flashing notification.
