Creating user cotrol

[man_luck]

I want to create my own user control.I know i have to start "Windows Control Library" project and then i can define property, events and/or methods.But the problem is i want to create readonly combobox.I drag and drop a cobo box on the form.Now how to define this property?

The code should go like this

 

Property ReadOnlyCbo() As Boolean

Get

 

End Get

Set(ByVal Value As Boolean)

 

End Set

End Property

 

Can anyone tell me what code should go inside. :o

Hey i have figured out how to make combo box read only without making a user control.

My code is as follows:

 

Private Sub cboDepartmentName_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboDepartmentName.TextChanged

cboDepartmentName.Text = ""

End Sub

 

though i have achieved what i wished to do but still i would like to know how to create user control readonly combobox.

Rather than create a user control you could create a new class and inherit from the existing combobox. You would then need to override the relevant events.

Not tested the following at all but it should give you the idea

Public Class ReadOnlyComboBox
   Inherits ComboBox


   Protected Overrides Sub OnTextChanged(ByVal e As System.EventArgs)
       Text = ""
   End Sub
End Class

Are you saying you only want the user to be able to select a value from the list and not change the text?

 

just set the DropDownStyle to 'DropDownList' as opposed to dropdown
