When you enable the AutoComplete feature of forms in Microsoft Internet Explorer and then you select any text from the AutoComplete drop-down list of a TextBox control in a Web application, the TextChanged event of the TextBox control does not fire even though the text in the TextBox control changes.
This behavior occurs because Internet Explorer cannot fire the TextChanged event of a TextBox control when you select text from the drop-down list by using the AutoComplete feature.
To work around this behavior, disable the AutoComplete feature of the Web form. To do this, follow these steps:
Steps to reproduce the behavior
Enable the AutoComplete feature for forms
Create a Web application that contains a TextBox control
Build and then debug the Web application
