array of checkBoxes

Hello Everyone!

I would like to dynamically create a few checkBoxes and insert them into a form.

FormCheckBoxControl cBox[];
//returns error "illegal basetype in array cBox

for(i=0;i<=10;i++)
{
cBox[i]. //there is nothing after dot :(
}

Is there any way to add array of elements to form with different names like in C#?

My final goal is form with possibility to choose BOM names, returning table with items they contain to compare. I just couldn't do it by report.

X++ doesn't support arrays of objects. Nevertheless you can use collection classes such as List and Array.

Can you tell us more about your actually requirement? There may be a better way to achieve it than generating controls at runtime.

Well, for example:

We have 5 BOM's, lets call them BOM0, BOM1... BOM4. Each of them contains few items inside. My leader want me to develop (for training) something (whatever it might be) to compare element inside BOM's.

You, Mr. Martin, suggested me to use SSRS report, what is, of course, perfect solution. But I decide to expand functionally of this "device".

I would like to create a form (I think, it's form) with CheckBoxes, where User will choose BOMs he want to compare. After that he receives complete tables with content of each BOM separately.

I know how to perform it in Visual Studio using .NET, but, sadly, it is far different than X++.

PS. Do you think that some day Microsoft will resign from X++ in AX creating new version of .NET usable both in casual object development and AX?

Why don't you simply use a grid with a checkbox column, for example? By the way, creating such controls in code would be weird in .NET as well, if you use data binding (and you probably should).

I don't see any problem in X++ - I don't even see any problem here that requires using code.

I have never herd bout data binding, so much knowledge in one conversation :)

Getting back to business. I have found possibility to add grid into a form and checkBox into it, but only manually. I can't find any information about adding full column of items.

Is it even possible in just and only AOT? If it will not be generated from code I have no idea how to dynamically adding and renaming them.

My main problem is that, theoretically, solution should work despite number of unique MOBId's.

Ok, the column is done, now I need some labels, and logic.

Should I generate separate label for each of items, or is there something like "text" property?

I see, there is no labels, this column is a part of table. Now it becomes clear :)

So logic...

Two questions:

1. How can I test wich checkBoxes on grid are checked?

2. How to create table where each record occurs only once (column a,a,b,a,c,c,c becomes a,b,c)?

Am I doing it correctly?

BOMVersion BV;

BOMId tempName;

while select * from BOMVersion

{

if(tempName != BOMVersion.BOMId)

{

tempName = BOMVersion.BOMId;

// in this place I would like to move my unique

// value into table in grid

}

}

And what can I do to populate table inside grid?

To your two questions:

1. Typically by filtering the table used as the data source for the checkbox.

2. Don't insert any record more than once. You can create a unique index to enforce that.
