In Noesis DisplayMemberBinding contains a BindingExpression, so you would need to do this:
public object Convert(object value, System.Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
if (value is List<string> config)
{
var gridView = new GridView();
foreach (string column in config)
{
GridViewColumn col = new GridViewColumn { Header = column});
BindingOperations.SetBinding(col, GridViewColumn.ColumnProperty, new Binding("[" + column + "]"));
gridView.Columns.Add(col);
}
return gridView;
}
return Binding.DoNothing;
}
We will investigate how to expose the type of that property correctly as a Binding object for a future release. |

Sorry for late response.
After creating this report I found a workaround for my case that uses entirely different approach and forgot about it.
Sadly, later I encountered this problem from different angle, but at that time I found solution on forum https://www.noesisengine.com/forums/viewtopic.php?t=1868
But now that solution doesn't work anymore too.
So, how am I supposed to dynamically create binding for DisplayMemberBinding property of GridViewColumn? |

The code will look like this:
public class ProvideValueTarget : IServiceProvider, IProvideValueTarget
{
public object TargetObject { get; set; }
public object TargetProperty { get; set; }
public object GetService(System.Type serviceType)
{
if (serviceType == typeof(IProvideValueTarget)) return this;
return null;
}
}
void UpdateColumnBinding(GridViewColumn column, string path)
{
Binding binding = new Binding(path);
column.DisplayMemberBinding = (BindingExpression)binding.ProvideValue(new ProvideValueTarget { TargetObject = null, TargetProperty = null });
