If you want to display none in ComboBox, in Properties Panel you can set Text Properties to none. The other way of changing it to none is by adding the below line in Form Load Event.

VB

ComboBox1.Text = "none"

The above code will help you to display none when you run your form. But it will not be displayed in the item list of your ComboBox. If your want it to be displayed in your list too, then you can right click on your ComboBox and click on Edit Items... A new window will get opened. Add none in the textbox there. Other way of adding none to the list is adding the below line in the Form Load Event.

VB

ComboBox1.Items.Add("none")

Hope this satisfy your question. If still you have any doubt you can post it in comments.

Simply you can insert two lines in the Form Load Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
ComboBox1.Text = "none"
ComboBox1.Items.Add("none")
End Sub

Public Sub LoadClusterInfo(ByVal clusterID As String, ByVal operation As OperationEnum, ByRef entities As RFDBEntities)
entities = New RFDBEntities
_clusterID = clusterID
_entities = entities
_operation = operation
_securityStatus = security.GetInstance.isDesigner Or security.GetInstance.isApprouver
If _securityStatus = False Then
If security.GetInstance.isAdmin Then
_securityStatus = True
End If
End If
cboHostsiteId.Text = "None"
cboHostsiteId.Items.Add("None")

SelectSecurity(_securityStatus)

FillFormCluster()
