Question User control 's property changed automaticaly on design time

[s_muhilan]

Hi
We developed a user control in windows form project by adding usercontrol.
User control

Text Box control 1 id TextBox1
Button Control id Button1
Text Box Control 2 id TextBox2
Text Box Control 3 id TextBox3

The controls has the following public properties.



Public Property IsTextBox1Visible() As Boolean

Get

Return TextBox1.Visible

End Get

Set(ByVal value As Boolean)

TextBox1.Visible = value

End Set

End Property

Public Property IsTextBox2Visible() As Boolean

Get

Return TextBox2.Visible

End Get

Set(ByVal value As Boolean)

TextBox2.Visible = value

End Set

End Property

Public Property IsTextBox3Visible() As Boolean

Get

Return TextBox3.Visible

End Get

Set(ByVal value As Boolean)

TextBox3.Visible = value

End Set

End Property



This control is used in a form which contains a tab control with 3 tab pages
When I drag this control to a tab pane control in tab page 2. It is showing three text boxes and one button.

After build and run time, I closed the project and reopen. I found that the text boxes and buttons are disapper in the design mode.

I changed the all properties to true in the desing mode and save the project. After sometime (run/reopen/go to the tab page) when I found that the text boxes are once again set to visible false automatically.

What is the issue?
