Find WPF control by Name

There's at least two ways to do that:

Use the FindName method of the parent container to find the control (but it'll internally involve looping, like the visualtreehelper)

Create a dictionary to store a reference for each control you create

var controls = new Dictionary<string, FrameworkElement>();controls.Add("_marketInfo5", lbl);

Then you can do:

controls["_marketInfo5"].Tag = timeNow;

You can use XamlQuery for finding your controls at run-time.XamlQuery In CodePlex

XamlQuery.Search(RegisterGrid, "Label[Name=_marketInfo5]").SetValue(Control.TagProperty, timeNow);
