Answer 1

Я нашел решение для удовлетворения требований, но ему нужен объект, связанный с Datagrid, имеет логическое свойство. Вот xaml:

<DataGridTemplateColumn Width="120">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <TextBox
                                Name="innerTextBox"
                                BorderThickness="0"
                                IsReadOnly="{Binding DisableEdit, UpdateSourceTrigger=PropertyChanged}"
                                Text="{Binding Name}" />
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>

и вот объект: открытый класс Person: BindableBase { имя приватной строки;

    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    private bool disableEdit;

    public bool DisableEdit
    {
        get { return disableEdit; }
        set { SetProperty(ref disableEdit, value); }
    }

}

А вот событие button_click:

        var person = datagrid.SelectedCells[0].Item as Person;

        person.DisableEdit = false;

Поместите UpdateSourceTrigger=PropertyChanged в привязку DataGrid вместо DataGridTextColumn
