Hi Dinesh,

Did you debug first to see if it enters your code or not? and if it reaches the line enabled(false)?

Debugging can sometimes answer the question.

And it seems you want to disable the button if accountType is changed, then why you didn't use modified method instead of active?

Thanks,

Please tell us more about the problem.

What did you find when you debugged your code? e. Does it execute when you want (I see you don't execute it when changing the value of AccountTyp) and does it behave as expected?

A hint: are you sure that selectionChange() method gives you what you want. Test it...

Note that your code for accessing the controls is wrong. Never hard-code names of applications objects, because it's then not checked by the compiler and you won't find references for it. Using a macro doesn't solve this problem. You can use formControlStr(), but an easier approach is using a CoC extension and referring to the controls just by name (e.g. element.AccountType).

Hi Dinesh,

You didn't answer our question about what did you find when debugging.

And I already suggested to do that on the modified method instead of active.

So you can choose the modified event handler for the accountType or CoC for the modified method of the accountType... I prefer CoC.

Hi Dinesh,

You will need to add the code on both init method of the form and modified method of the control/form datasource field.

Init method, so that if the account type matches the condition when you first open the form. And modified method when you actually modify the accountType value.

Hi Dinesh,

Try to put your code on the active method if you want to enable/ disable the button when you open the form and on the modified method for the combo box that you mentioned.

Thanks,
