how to add items into listview without binding WPF

I want to add some items to a listview that is a gridview. I want to do it through code without implementing the binding option, Simply adding values to set of cells of some sort.
I know it's not the WPF-way but I need this done urgently and I can't seem to find the answer I'm looking for.
I looked at multibind, converters and regular binding but it just won't give me the answer I need for now.

Is it even possible?
If so how can I do it?

You need index bindings like "[0]".

<Grid>
    <ListView x:Name="lv" />
</Grid>



lv.Items.Clear();
var gv = new GridView();
lv.View = gv;

var columns = new List<string> { "col1", "col2" };
for(int index = 0; index < columns.Count; index++)
{
    gv.Columns.Add(new GridViewColumn
    {
        Header = columns[index],
        DisplayMemberBinding = new Binding("[" + index.ToString() + "]")
    });
}

// Populate list
var row1 = new List<string> { "(1, 1)", "(2, 1)" };
var row2 = new List<string> { "(1, 2)", "(2, 2)" };
lv.Items.Add(row1);
lv.Items.Add(row2);

Don't get hung up on whether to load or not load controls in codebehind. I have worked major Silverlight projects where it was a mixture of both operations. 

public MainWindow()
{
    InitializeComponent();

    lvPrimary.ItemsSource = new List<string> { "Alpha", "Beta", "Gamma" };

}

With Xaml looking like this:

<Window x:Class="WPFStackOverflow.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <ListView Name="lvPrimary" Width="200"/>
    </Grid>
</Window>

Can you use a DataGrid instead of a ListView? Then you can set AutoGenerateColumns to true (is true by default even).

<DataGrid x:Name="myDataGrid" AutoGenerateColumns="True"/>

Then in the code behind do something like this:

myDataGrid.Items = new List<MyDataType>();
foreach(var item in itemsToAdd){
    myDataGrid.Items.Add(item);
}

or shorter:

myDataGrid.ItemsSource = myListOfItems;
