UpdateSourceTrigger.Explicit

When using Explicit trigger mode, you can update the bound data by simply calling the SetPropertyValue method from your view. This will send the changes down to the model.

For exampe, supposed that we have a button click in the View where we want to update the model explicitly, the following code should do the job.



 textView.SetPropertyValue(BindableProperties.TextProperty, "New value");

The SetPropertyValue takes 2 parameters, the bindable property to update and the new value. You will typicallycall this method against the target view, in the above case, the text view. So, if the text view is bound to any model (two-way binding mode will be required), then all bound models will be updated accordingly.

Hope this helps.

The textbox I use never gets an actual focus it is a placeholder that I use to set the value in native. What other way can you think of to grab the data out of the textbox?

Please try to set the UpdateSourceTrigger to PropertyChanged. By default, text will be updated on lost focus.

Hope this help.

How do you activate the trigger?

I have update text in native iOS and it isn't updating in the core. How can I trigger the binding provider to recognize the change of text?
