Hi,

I need a FilterEditorTemplate (and FilterItemTemplate) for a TemplateColumn that will filter (via Contains operator) the rows of the grid where the ItemTemplate shows a simple TextBlock and the EditorTemplate has a combobox whose ItemsSources vary from row to row.

I know I could do this if I had access to the whole list of possible options that this column could contain, but the reason why each row has a restricted list of values for each combobox is because it would require loading masses more data (10x+) than what the rest of the grid would normally hold! Hence the use of multibinding to set the ItemsSource's depending on another parameter. The converters and multibinding work fine.

The problem is that I don't know the underlying filter system very well and there are very few example that even come close to the issue I have here.

I have attached the TemplateColumn's xaml so that might help.

Any help would be very much appreciated as this is the final part I need to complete for this module.

Thanks,

Alex
