Yes... but that would be the easy way out and we wouldnt be programming Micrrosoft products if we settled for that... ;) 

no, actually, I have about a dozen types of logs that contain the same core data, but each log has different sets of property data that would be within the collection.  I would like to avoid defining on specific class for each of the log types.  What I would like to do is have a generic class that contains the core data and then a collection of log entry proprties for the variable stuff.  The collection would contain the property name, ID and value.  When I get my log back I want to create the columns for that log type dynamically, then as I'm populating my rows, assign them to the specific properties within the sub collection.

Hi Marc, 

Then i'd recommend using a Custom Column. 

Here is some code to get you started:

Step 1:  Create a Custom Column and ColumnContentProvider:

public class MyColumn : TemplateColumn

      {

            protected override ColumnContentProviderBase GenerateContentProvider()

            {

                  return new MyColumnContentProvider();

            }

      }

      public class MyColumnContentProvider : TemplateColumnContentProvider

      {

            public override FrameworkElement ResolveDisplayElement(Cell cell, Binding cellBinding)

            {

                  FrameworkElement elem = base.ResolveDisplayElement(cell, cellBinding);

                  if (elem != null)

                  {

                        MyDataObject mdo = cell.Row.Data as MyDataObject;

                        if(mdo != null)

                        {

                              elem.DataContext = mdo.Properties[cell.Column.Key];

                        }

                  }

                  return elem;

            }

      }

Step 2:  Create a generic DataTemplate:

<DataTemplate x:Key="colTemplate">

<TextBlock Text="{Binding}"></TextBlock>

</DataTemplate>

Step 3:  Generate your Columns:

DataTemplate template = this.Resources["colTemplate"] as DataTemplate;

this.DataGrid1.Columns.Add(new MyColumn() { ItemTemplate = template, Key = "Prop1" });

this.DataGrid1.Columns.Add(new MyColumn() { ItemTemplate = template, Key = "Prop2" });

this.DataGrid1.Columns.Add(new MyColumn() { ItemTemplate = template, Key = "Prop3" });

What i'm doing:

Basically, i create a custom column, with a  custom content provider, that changes the DataContext of the binding of the my DataTemplate.  The data i'm creating is a Dictionary, which i'm assuming you're using as well. 

My DataTemplate, just creates a straight binding, with no property path, b/c the datacontext i'm binding to is the value that i want to display. 

Then i just walk through and generate my columns.  Note, i'm using my column key to determine the properties from the Dictionary. But since this is your custom column, you can add additional properties and customize it to your wishes. 

Hope this helps,

We are trying this solutions but we can't find the "MyDataObject", what is it for ?

Thank you

That just mock data. 

You would replace that with your own data object.

Sorry but I don't understand, is it possible to have the full code of the example ?

Thank you very much

MyDataObject isn't real data. Its just some dummy data. 

If you were bound to a collection of objects of type Customer, you would replace MyDataObject with Customer. 

This was suggested as solution for someone, that needed to access a specific property on their data, which required it to be cast as that object. 

I hope this clears things up.
