Binding to dynamically created controls - wpf

Question

I'm having trouble binding values to dynamically created controls. When a user loads a custom file and that file will have a unknown number of arguments. Arguments have a Group property that when grouped will dynamically add tabItems to a tabControl. I then loop through the arguments and add a label and, for now, a textbox to a grid inside the tabs. though i intend to use different controls depending on the arument type. I want to bind the argument Value property to the textbox. The tabs, labels and textboxes are added fine but, no value binding
He if my not yet re-factored solution so far;
myTab.Items.Clear();
var args = viewModel.Arguments;
var groups = args.GroupBy(arg => arg.Groups);
foreach (var group in groups)
{
TabItemExt tab = new TabItemExt();
tab.Header = group.Key;
Grid grid = new Grid();
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
int count = 0;
foreach (var argument in group)
{
RowDefinition newRow = new RowDefinition();
grid.RowDefinitions.Insert(count, newRow);
LabelTextBlock label = new LabelTextBlock();
label.Text = argument.DisplayName;
Grid.SetRow(label, count);
Grid.SetColumn(label, 0);
TextBox textBox = new TextBox();
var binding = new Binding();
binding.Source = viewModel.Arguments[argument.Name];
//binding.Source = argument
binding.Path = new PropertyPath("Value");
textBox.SetBinding(TextBlock.TextProperty, binding);
Grid.SetRow(textBox, count);
Grid.SetColumn(textBox, 1);
grid.Children.Add(label);
grid.Children.Add(textBox);
count += 1;
}
tab.Content = grid;
myTab.Items.Add(tab);
}

Answer 1

textBox.SetBinding(TextBlock.TextProperty, binding);
should have been
textBox.SetBinding(TextBox.TextProperty, binding);
just a little over dependent on intellisense.
