WPF TextBox.Text can be out-of-sync with databinding

Scope

Edge

Version Introduced

4.5

Source Analyzer Status

Planned

Change Description

In some cases, the xref:System.Windows.Controls.TextBox.Text property reflects a previous value of the databound property value if the property is modified during a databinding write operation.

• Quirked
• Build-time break

Recommended Action

This should have no negative impact. However, you can restore the previous behavior by setting the xref:System.Windows.FrameworkCompatibilityPreferences.KeepTextBoxDisplaySynchronizedWithTextProperty property to false.

Affected APIs

• P:System.Windows.Controls.TextBox.Text
