hi,

i have a window based vb.net application with 2 forms and 1 usercontrol.

In Form 1:
1 listbox and 1 button.

In Form 2: [main form / start-up form]
1 tabcontrol [named tabs]

In Usercontrol [named createcontrol]:
1 Textarea

On form2 load event:

Dim NewTab As New TabPage
  With NewTab
  Name = "some name"
  .Text = "some text"
End With

Dim myChat As New createcontrol()
NewTab.Controls.Add(myChat)
tabs.TabPages.Add(NewTab)

like textbox.text = selected [text from list box]

That is a very bad idea.

It ties the design of the top items together: you can't change the UserControl without it affecting the users of the control, and them being forced to make changes to working code.

Instead, set up a public property in the the control which you can set and get the value of, which puts the string to the appropriate TextBox. That way, you could later replace the TextBox with (say) a ComboBox without affecting the outside world.

Hi,

There are two methods by which you can achieve this

1. Make your textbox Object public and use it directly(Not Recomended for the point of View of OOPS).

2. Create a public function\Property in your user control and use it to assign values.
