Wpf datagrid binding not updating 100 online dating in usa
It turns out that while the Data Table behind is happy to update itself and other things bound to it will update their collections, even with Auto Generate Columns set to true, the Data Grid just happily ignores the new column and doesn’t display a thing. Add(columnname); // Create new Data Grid Column (could be of any type, just picking text here) Data Grid Text Column dgtc = new Data Grid Text Column(); dgtc. Binding = new Binding(columnname); // This is the important part to get it to hook itself up to the Table behind. Notify Property Changed("My Data Table"); Notify Property Changed("My Data View"); And voila, a fully connected and expandable Data Grid.
The solution I finally came upon requires that you create your own column on the Data Grid to bind back to the column added in the Data Table. You should find out more about what this was used for in a few weeks.

It was a nightmare and I any example I found just stopped at loading initial data in. Add(dgtc); // Notify any one bound to these properties there's an update, as per the usual!
