Expandable columns in a datagrid
- by Jobe
Im working on a WPF-applications to present and correct large amounts of data.
Im about to implement a datagrid containing data from 3 different sources that are populated from external services.
To start with I will only populate the grid with data from one source, the master source.
However, sometimes an automated validator will trigger a validation warning or error on one cell and the requirement states that the user should be able to view data from the additional 2 sources in columns next to the selected one.
Something like this:
Standard view:
| col1 src1 | col2 src1 | col3 src1 |
| | | |
| |faulty | |
| | | |
User want to show data from source 2 and 3 next to the column "col2 src1" like this:
| col1 src1 | col2 src1 | col2 src2 | col2 src3 | col3 src1 |
| | | | | |
| |corrected | | | |
| | | | | |
and then be able to correct the faulty formatted cell with data from the other 2 soruces, and then collapse the columns again.
I am trying to use the mvvm pattern on this one so I have populated the DataGrid with a ListCollectionView so far.
The list contains items with properties like this:
MyRowItem {string col1, string col2, string col3}
I will then have 2 additional collections with items of type like above but from 2 other sources.
I have no idea how to implement this functionality and could use some help on the logics.
What approach should I head for?
