Hi Daniele,
I have tested for this issue here, but never encountered the above mentioned problem. I have created a
sample_application in v2.0.1.0 as per your directions above and have attached it here. In this sample, I have 3 TextBoxes - TextBox1 placed on the form, TextBox2 placed within a DockingClientPanel and TextBox3 placed within a docking window. I have wired the MouseEnter event to each one of them, and display an appropriate message whenever the mouse enters any of them. When I tested this here all the 3 TextBoxes respond to the MouseEnter event correctly. Please take a look at the sample and let me know if this meets your requirements. If not, kindly modify it to show the problem. Also. let me know the version of Essential Suite that you are using. I would appreciate if you could send me this information by opening a new incident in DirectTrac in this regard, so that I could update you there from now on. Thanks for your cooperation, and continued interest in Syncfusion products.
