Cannot type in Combobox in non-TopLevel Form

[plocks]

I have a program that opens up a blank form. When the users clicks a button, multiple new forms are brought up within the original form. When doing this, all ComboBoxes in the new forms become uneditable by the user. They can select from the drop-down menu, but they cannot click into the combobox and type.

The comboboxes work fine if I do not open them within the main form. They are all set to "DropDown" style.


Below is some code.

Private Sub btnOpenForms_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpenForms.Click

'Open Account_Information form
Account_Information.TopLevel = False
Account_Information.Visible = True
Me.Controls.Add(Caller_Information)

'Open Addresses form
Addresses.TopLevel = False
Addresses.Visible = True
Me.Controls.Add(Addresses)

'Open Notes form
Notes.TopLevel = False
Notes.Visible = True
Me.Controls.Add(Call_Notes)

'Open Services form
Services.TopLevel = False
Services.Visible = True
Me.Controls.Add(Services)

End Sub


Any help with this would be greatly appreciated.

Have you tried using the SetTopLevel method of the control?

I don't have the option. I'm using VB2008 and I think SetTopLevel is not supported for controls.

This has been solved by changing the forms to mdi
