Problem Fixing a ComboBox in Xaml
If you define a variable called 'xaml' that has the following value:
If you fix doing the following:
It will work in version 14.1 but in version 15 I am getting the following error:
Why is that ?
- Code: Select all
<Window

<ComboBox

HorizontalAlignment="Left"
Margin="129,95,0,0"
VerticalAlignment="Top"
IsEditable="True"
IsReadOnly="True"/>
</Grid>

If you fix doing the following:
- Code: Select all

obj←XamlReader.Parse(⊂xaml)

- Code: Select all
EXCEPTION: 'Cannot set unknown member 'System.Windows.Controls.ComboBox.IsReadOnly'.' Line number '16' and line position '10'.
Why is that ?

Re: Problem Fixing a ComboBox in Xaml
I'm not getting any error (W10 and Dyalog APL/W-64 Version 15.0.28601).
Wondering whether your V14.1 and V15 might be connecting to different versions of Microsoft's .NET morass.

Re: Problem Fixing a ComboBox in Xaml
Hi Pierre,
On this computer, does 15.0 work with other XAML WPF code?
Can you send Support the text of your ⎕exception and ⎕exception.InnerException if there is one please?
Your code works for me on Windows 7 and Dyalog 15.0 64-bit Unicode with these assemblies:

Re: Problem Fixing a ComboBox in Xaml
I have found this post on the web that is similar to my problem. Parsing the following line before parsing the original Xaml is a workaround of the problem that is working for me (as explained in the post). A little bit weird to my taste.
- Code: Select all
inter←'<ComboBox xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" IsReadOnly="True"/>'
⎕USING←⊂'System.Windows.Markup,WPF/PresentationFramework.dll'
inter←XamlReader.Parse(⊂inter)

Re: Problem Fixing a ComboBox in Xaml
Hello Pierre,
We are unable to reproduce the problem here. I've done a little online research, and the consensus seems to be that it’s a Microsoft bug.
Here are a few links that I found (but I suspect you've seen them)
http://stackoverflow.com/questions/6850 ... isreadonly
https://social.msdn.microsoft.com/Forum ... ?forum=wpf
http://connect.microsoft.com/VisualStud ... n-combobox
That last link doesn’t appear to work, but the URL text suggests it *might* be a beta-2 problem. Are you confident that you have an up to date (or at least a non-beta) .Net 4?
Best Regards
John Daintree.

Re: Problem Fixing a ComboBox in Xaml
Hello John, my computer did some 'Windows Update' automatically since I wrote that post and now everything is working fine. I am working on a Window 7 Professional with a .Net version 4.6.2 now.
I agree with you that it is a Microsoft bug, but I still don't understand why the same code was working on my previous v14.1 and not on v15. I am using the following for my 'dyalog.exe.config' file on both version of the interpreter:
Is it me that is doing something wrong with my 'dyalog.exe.config' file ?
Thanks,
Pierre Gilbert
