BindingExpression.UpdateSource method

Sends the current binding target value to the binding source property in TwoWay bindings.

Syntax


public:
void UpdateSource()

Parameters

This method has no parameters.

Remarks

If the UpdateSourceTrigger value of a two-way binding is set to Explicit, you must call the UpdateSource method or the changes will not propagate back to the source.

Calling this method does nothing if the Mode value of the binding is not TwoWay.
