Question

I have looked into the documentation for dynamic objects but i wasn’t able to find a solution
to my current problem.

I have this code :

dynamic sampleObject = new ExpandoObject();

string columnName = checkBox.Content.ToString();

sampleObject.columName = myObservableCollection;

Now, the name of my added property will be columnName, but I would like it to be the content of my checkbox.

How should I implement that ?

Thanks

Use a dictionary of named values instead of dynamic properties.

You can use a Dictionary converter to bind to specific entries in the dictionary (using the converter parameter value as the key). Code below from this link

public class DictionaryItemConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        var dict = value as Dictionary<string, string>;
        if (dict != null)
        {
            return dict[parameter as string];
        }
        throw new NotImplementedException();
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

Where you add columns to the grid via code you will need to create a binding with the correct converter and name converter parameter.
