The link is dead.

These articles are great.

I did have a bit of trouble for bit there as I had bound my source to Dictionary.Values, but after reading through the comments I was able to bind the source directly to the Dictionary as suggested and then change my data context to ‘Value’ in the XAML and it worked like a charm.

One stumbling block I ran in to was that the ObservableSortedDictionary constructor requires an explicit IComparer object whereas the base SortedDictionary does not. Your observable version would have been a lot easier to drop in if it also used a default comparer when none is supplied.

_dictionaryCacheVersion = -1;

Something like:

private void Control_Loaded(object sender, RoutedEventArgs e)
{
// MyDataItem would contain a reference to a data source and key
// the tag is assigned to be MyDataItem created using a IMultiConverter defined in the xaml

MyDataItem dataItem = ((sender as FrameworkElement).Tag as MyDataItem);

Binding b = new Binding(”["+dataItem.Key+"]“);
b.Source = dataItem.DataSourceWithIndexer;

if (sender is TextBox)
{
(sender as TextBox).SetBinding(TextBox.TextProperty, b);
}
}

This works, but was hoping to do this within the XAML.

Also, is it correct to set Binding in the Load event?

Thanks again

e.g. Path=’.[{Binding indexerKey}]‘

Does anybody know or can tell me a way of binding to a dictionary using a dynamic key.

e.g. Path = “.[]”

I’ve used your (Dr WPF) ObjectReference class in combination with the controls tag property to hold the key info, I’ve also tried MultiBinding.

The problem i have is converting back, unless the path can be set dynamically (which is difficult not being a dp) I have to update the data source (indexer) from within the converter which is obviously wrong and bypasses validation.

Has anyone got any ideas?

TIA
