Question

I have a datagrid with a variable number of columns that I am generating programatically. It contains DataGridTemplateColumns, each with a DockPanel containing a CheckBox and a TextBlock.

Binding code:

    Binding bindingPicked = new Binding(string.Format("Prices[{0}].Picked", i));
    bindingPicked.Mode = BindingMode.TwoWay;

CheckBox code:

    FrameworkElementFactory factoryCheckBox = new FrameworkElementFactory(typeof(CheckBox));
    factoryCheckBox.SetValue(CheckBox.IsCheckedProperty, bindingPicked);

Picked property:

    private bool _picked;
    public bool Picked
    {
        get { return _picked; }
        set { _picked = value; }
    }

When the datagrid is initialized, the Picked getters are called as expected. However, when I check/uncheck a checkbox, the setter isn’t called. What is causing this? I do not want to use a DependencyProperty, and I don’t think it should be needed as I just need the property setter to be called when the user clicks the CheckBox.

EDIT: Apparently I am a moron, I simply forgot
bindingPicked.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
Feel free to close this.

Answer 1

bindingPicked.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;

That should do it 🙂
