Hi All,

I would like to write if condition in X++ language.

if one field value is equal to "Some string" then its true part.

I dont know how to take the field value

In VBA, we can write like if(field.value="String value")then true part..

Anybody can help me.

Regards,

Neethu K B

Hi,

You can write like operator for your string value or also you can use field.value="String value" as you mentioned.

Thanks

Hi,

If you want to check the string value using field, then in design you need to change auto declaration property to yes as Kavitha said.

If I'm thinking wrong solution, please explain your question bit more.

Thanks

You didn't provide any context, so it's hard to guess what should be the right name of the variable. Nevertheless you're also using a wrong operator: '=' is for assignments, while you want comparison, which is done by '=='.

As you've already found, other language use different syntax than VBA, therefore you have to first learn how to use them. Read X++ Language Programming Guide on MSDN, for instance.

Where are you trying to add this code? On a form? If so where are you selecting your value from? is it just a form level field or it comes from the form data source?

We can't answer your question if we don't know where you are trying to add the condition and where is the field that you want to compare. Please elaborate.
