Is this in a container or a web viewer?
I have a web viewer in one of my DBs and improved performance by putting it inside a tab control so that I have to click the tab to show the tab panel that contains the web viewer.
It is a web viewer. That would be too simple. I will put the web viewer on the second tab and place the layout for other data on the first tab.
Not exactly what I want but it will work, Thanks.
You can also store the URL in a separate field and Set up the Web Viewer's calculation to return null instead of the value of the URL field until a button is clicked that sets a value--thus "turning on" the web viewer.
The web viewer might use:
If ( ViewerOn ; URLFieldHere )
The script might be:
Set Field [ YourTable::ViewerOn ; Not YourTable::ViewerOn ]
And ths will "toggle" the viewer on and off. (Might need a commit records after the set field to get the layout to update.)
