DataGrid: dynamic DataTemplate for dynamic DataGridTemplateColumn
- by Lukas Cenovsky
I want to show data in a datagrid where the data is a collection of
public class Thing
{
public string Foo { get; set; }
public string Bar { get; set; }
public List<Candidate> Candidates { get; set; }
}
public class Candidate
{
public string FirstName { get; set; }
public string LastName { get; set; }
...
}
where the number of candidates in Candidates list varies at runtime.
Desired grid layout looks like this
Foo | Bar | Candidate 1 | Candidate 2 | ... | Candidate N
I'd like to have a DataTemplate for each Candidate as I plan changing it during runtime - user can choose what info about candidate is displayed in different columns (candidate is just an example, I have different object). That means I also want to change the column templates in runtime although this can be achieved by one big template and collapsing its parts.
I know about two ways how to achieve my goals (both quite similar):
Use AutoGeneratingColumn event and create Candidates columns
Add Columns manually
In both cases I need to load the DataTemplate from string with XamlReader. Before that I have to edit the string to change the binding to wanted Candidate.
Is there a better way how to create a DataGrid with unknown number of DataGridTemplateColumn?
Note: This question is based on dynamic datatemplate with valueconverter
