Hello Sir,

My VB.NET window application on Visual Studio 2008 hasa user control applied on some forms in same application.

The user control, having two textbox controls and a button control,has been put in different tabpages of system.windos.form.tabcontrol in forms.

Though the Controls remain visible for first 2 or 3 successful executions and works fine but afterwards the textBox and button controls visible property becomes false making them invisible in design mode as well as running mode.

The usercontrol's visible property remains True only the inside child controls visible property becomes False.I have ensured that incodebehindno such kind of code has been written.

Can youhelp me out by giving some solution of it.

Regards,

Deepak Kumar Mohanty

Hi Deepak,

We need to trace all the places referencing the Visible property and Hide method of he controls to check if we hide the controls at some places. These are the methods to trace the places:

1. Press Ctrl + F. Then type “Visible�or “Hide�and click OK.

2. Right click the Visible property or Hide method, and select Find All References. Then you would see the results in Find Symbol Results view.

It is appreciated if you could create a small project in which the error can be reproduced and email that project to me. So that I can debug the program and figure out the root cause. My email is alala666888@hotmail.com.

Let me know if this helps.
