Question

How do I add row data directly to a DataGrid Class?

I am using a free opensource class from a company that I will not name (even if it is RadiantQ) that I like a lot. It has this cool MuLtiColumnTreeList control that is a combination of a tree control and a datagrid. It comes with an example code that you can look at and everything. It is pretty cool. It is inherited from the DataGrid class.

The problem is that I am kind of new to databinding on this level and so I would like to just go ahead and write some code that forces the data that I have gathered from another class into the control.

So I looked online for how to do that for a DataGrid class and the information is not easily available. Can anyone help?

It seems that once the databinding is done, and if you change the data you have to rebind to the control. This is what was giving me difficulty before. So what I have to do is run some command like this:

this.mutlicoolgridview.ItemsSource = null;
this.mutlicoolgridview.ItemsSource = SampleData.GetSampleDataNew();

The problem I am having now is this. After running his command about one thousand times, I actually run out of memory. I think that doing this:

this.mutlicoolgridview.ItemsSource = null;

is not such a good idea. Is there a better command to do to free up the memory?

This is a similar looking crash:

If you have a List of objects, you can copy them to a BindingList. Then you can use

dataGrid.ItemsSource = myBindingList;
