Limiting function on aaTrendControl

I believe the only way to achieve this is to hide the enture toolbar (there's a property for this but I don't remember its name). I'm not sure if it is possible to hide or disable individual commands.

I second this, only the full top line tool bar can be hidden, individual commands cant be disabled

Hi Richard, thanks for the reply. I did have a look for such a property but couldn't find anything.

Do you know how to hide the toolbar ?

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).

Result:

Example of a Property set in DataBinding, linked to a CustomPropery

Some various script examples

The documentation that I have located is the AVEVA Trend Client Control User Guide, TrendClient.pdf)

I must say that this control is one of the most populated properties that i have seen, and just scrolling through them takes forever, so I must say that I always thought that everything is possible here, I just need to find the right property!

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

I hope it helps.

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!

Thanks Richard,

I just couldn't find the anything in the bindings that made sense to me.  I thought it would be possible to hide the whole tool bar which would have been ok but not perfect.  As you say now I see it it is rather obvious. 

Thanks again Richard Köhlerstrand you're a star. I will be able to finish migration of the system now. Will let you know if I have anything else I can't figure out.
