You cannot call the mainform from the subform.
If you want to do this, you need to do that using a singleinstance codeunit. The subform sends some info into it and the mainform gets the info from it by using some code in the OnAFterGetCurrentRecord-trigger or the OnTimer trigger.

Haven't tried but you could do something like this:
1. Create a global bool variable on the subform (var1)
2. When the delete is done set var1 to TRUE
3. Create a function on the subform (GetVarValue) whith this code: EXIT(var1)

4. From the mainform call the GetVarValue function to know if you have to disable the button

I think the correct way to do this use OnTimer trigger of mainform because if you go anyother way there must have refersh problem either you have done it perfactly.

as far as my personal experience that i have tried.

Don't go hacking away with these kinds of things. the best way is the Navision way : don't try to enable or disable the button, but have the code that is called from it check if there are lines or not, and give an appropriate message to the user. Easy, and no messing about with timers etc.

Hi,

If the requirement is absolutely required, search the forum for "Update Main form from subform using XML"
Here is one of the topics returned:

You can use the XML solution that is suggested by Garak, it works perfectly
