Limiting function on aaTrendControl

Question

Hi all, 
 I am using the aaTrendControl to access data from our Historian and I need to disable \ restrict access to the file load, file save and server config icons, see below. Anyone done this before or know how to ? 
 
 Thanks in advance

Hi David. Expecting that you use the .Net version the aaTrendControl embedded in a Industrial Graphics Symbol. There are several properties available in the editor where you can set various settings related to the functionality of the trend. But some has to be set using a reference or scripting. Here are a collection of some examples that i have created in some different scenarios. But this will Hide the Toolbar, you could set it in the OnShow script of the symbol, (and if needed you can have it appear based on logic).

And if you remove the toolbar I expect you could create your own buttons triggering the same functionality as needed. I hope it helps. Richard

 I did manage to find the exact solution for you as well! 
 As mentioned, the trend control includes a lot of trial and error since it contains a VAST number of properties and functions. Most of them undocumented. 
 And to be honest when I personally need to do something with it, I use autocomplete or the property list, adding some patience and luck ;) 
 Using the above mentioned method this morning i stumbled upon an interesting function! 
 .SetToolbarButtonEnabled 
 
 Using this you can individually enable or disable buttons in the toolbar! 
 
 'This will disable the Open button aaTrendControl1.SetToolbarButtonEnabled(0,0); 'This will disable the Save button aaTrendControl1.SetToolbarButtonEnabled(1,0); 'This will disable the Print button aaTrendControl1.SetToolbarButtonEnabled(2,0); 'This will disable the Copy button aaTrendControl1.SetToolbarButtonEnabled(3,0); 'This will disable the Servers button aaTrendControl1.SetToolbarButtonEnabled(4,0); '.... And so on 
 So obvious now that we know about it. 
 So thanks David for asking, now we know it IS possible. And of course we want to do this is in some scenarios! rickard.norin Heroes HQ , making the impossible, possible!
