GridPickerColumn Not working in 16.x
Hi.
I use in a project your component datagrid with a gridColumnPicker.
In version 15.4.0.x all is working.
If I use 16.xxx the gridColumnPicker doesnt work. When I click on the cell the picker is not displayed.

I put the VS trace when I click on gridCell.

Hi.
My viewmodel constructor is :
Thanks for your response
Your example works actually, but is 'quite' simple.
I have a mvvm architecture with IOC, so i can't have a 'view model' with a parameterless constructor.
So the syntax :

So the syntax :

In version 15.x, the binding : ItemsSource="{Binding Source={x:Reference rootElement},Path=BindingContext.ListUnites}" works perfectly.

root element is the content page.

Why not working in 16.x?
I will try to modify your example next week.

Hi Vincent,
Sorry for the delay.
We have checked your query. The issue for the “GridPickerColumn is Not working in 16.x” which is working fine in our side. The issue may be arise for you because you have used a ValueMemberPath and DisplayMemberPath property from a different collection that is differ from viewmodel collection. We have cleared mentioned in the UG stating that the ValueMemberPath and DisplayMemberPath should be from the same underlying collection that set for their respective MappingName.
You can also refer the UG from the below link:

Jayaraman.

Hi Jayaraman,
Attachment: SfGrid_Sample_21803b3c.zip
I don't understand what is the problem.
I have done a new example in attach file based on your online documentation (https://help.syncfusion.com/xamarin/sfdatagrid/column-types?cs-save-lang=1&cs-lang=csharp#customization-of-picker-dropdown-values).
The picker still doesn't work.
Thank you.
Thank you.

Vincent

Hi Vincent,
Sorry for the inconvenienced caused.
We have checked your query. The query for the “GridPickerColumn Not working in 16.x” is able to reproduce from our side when setting the ValueMemberPath and DisplayMemberPath as the same datatype for the GridPickerColumn in the latest version of our NuGet. We have also logged it as bug report. We will fix the issue and it will be rolled out for the upcoming release of our 2018 Volume 1 - service pack 2.

Jayaraman.
