Disable ComboBox Hyperlinks

Kevin Marois

Overview I have a DataGrid with a DataGridTemplateColumn with a combobox inside it. The combobox is populated by enums using an ObjectDataProvider. The ComboBox DataTemplate renders the enum items hyperlinks. Problem I want to disable hyperlinks that should not be clickable based on some value on the entity. I'm not sure how to go about this. [Here is a screenshot of the grid](https://1drv.ms/u/s!AjBmoYAYz\_v2hAxYsAuT5HGVloZ3?e=FCfEIx) and here's the XAML

If it's not broken, fix

What's wrong with binding the IsEnabled property on the Hyperlink to a property on your view-model?

It would need to be bound to a property on the entity - except there is no entity. I'm loading the combo box with enums.

If it's not broken, fix it until it is. Everything makes sense in someone's mind. Ya can't fix stupid.

Use a DataTemplateSelector as the ComboBox.ItemTemplateSelector. The SelectTemplate() method will be passed each item, (the enum in your case). Select a data template specific to each case you want.
