Why I get the message Two-way binding requires Path or XPath.?

Question

I am creating a TextBox and a TextBlock at runtime and bind that to the database fields at runtime. The code is below:

LstConfigFields = dbContext.ConfigFields.Where(c => c.ConfigId == this.Uid).ToList();
foreach (ConfigField rec in LstConfigFields)
{
    TextBlock TBlock = new TextBlock();
    TBlock.Text = rec.TextBlockText;

    TextBox TBox = new TextBox();                
    TBox.SetBinding(TextBox.TextProperty,new Binding(rec.DatabaseField));

    if ((bool)rec.IsVisible)
    {
        stackPanel1.Children.Add(TBlock);
        stackPanel1.Children.Add(TBox);
    }
}

But I am getting this message :

Two-way binding requires Path or XPath.

Where am I going wrong?

Answer 1

If DatabaseField is read-only you should use OneWay Binding.

Answer 2

If the Text property of the bound object contains symbols specific to XPath syntax, dynamic binding will try to interpret them, thus failing you the whole process by creating wrong binding
