AX 2012: ActiveX field takes focus in form

Hi experts!

I have a form with a group holding only one field and that is an ActiveX field of type "Adobe PDF Reader".

In my form I have some lines and every line contains a field with the name of the PDF file that I want to be shown in the ActiveX field when I select a line. So when I go from one line to another, the ActiveX field also changes so it shows the matching PDF file.

It works fine.

In the datasources "Active" method I call my ActiveX control like this: activeX.loadFile('myFile.pdf');

The problem is that the Activex field takes the focus every time loadFile is called. When I click on a line, it shows the correct PDF file, but when I press "arrow down" on the keyboard I don't move to the line below, but the PDF file moves a little inside the ActiveX field. (So if I do that a lot, I can soon see page two of the PDF file.)

How do I keep focus on the line and field, I am in?

Hope you can help...

Hi!

I have created the form with ActiveX field (like you are described) in the group. The form contains the grid also. And the focus still remain on a grid when i move the cursor.

Try to call myField.setFocus() method after activeX.loadFile('myFile.pdf').

RE: AX 2012: ActiveX field takes focus in form

Hi,

Thank you for your time.

I am standing on a grid in the datasources "Active" method. How do I get an object that I can call setFocus on?

I want the user to remain on the field in the same row as it was. I guess I have to get the current row and the current column and after "loadFile", I can call setFocus.

But how do I get the current row and column so I can call setFocus on that object?

Just set AutoDeclaration property's value to YES on the field on the grid and then call setFocus(). The row will be the same, this method doesn't affect the row position.

I still don't know which column (field) I am on. If I in the "Active" method calls "element.selectedControl().name()" it always returns the name of the grid and not the grid + the field like "myGrid_myField".

AutoDeclaration is YES on every field in the grid, and I have tried calling setFocus() on the first field in the grid, but that doesn't change anything. The ActiveX field still steals my "arrow down" keystroke.

Could you share some screenshots of form design, activeX control properties and active() method code, please?

I have copied my form and removed everything else from the form. So now it only has one grid (with one column) and one ActiveX-field.

So, in the active() method put ActiveX.enabled(false); before ActiveX.loadFile().

Then override mouseDown() method on the GroupPictureGroup methods and set ActiveX.enabled(true);

Wow, it works!

I've done what you wrote, and now the grid and the field works perfectly.

I have an extra question: If I move to page two in the pdf file, and then go one line up in my grid, then the other pdf file is also showing page two. The same goes for zooming etc.

Is there a way to reset the field, so it forgets that the user wanted to see page two? (So that when I show a new pdf file, it always shows page one.)

Hmm..I have tested the behaviour that you are described. My form always reset the field...
