Read-only combo box

[shevo]

What is the the best way to make a combobox which is binded to a datasource read-only. Although the Enabled property works, but it makes the combobox too dim to be able to be visible to end user.
I realised that there is no Read-only property for combobox.
Thank You.

Set the DropdownStyle property to DropDownList.

Even when I set to dropdownlist, there is no read only property.
I dun want user to select any thing from the list. That means when they clicked the drop down error, nothing will happen.The combo is only for displayed purpose till they click an edit button which reset the property back to dafault.

You may want to use a ListBox instead of a ComboBox. You can set the ListBox's SelectionMode to None so the user cannot select any items.

If it is for display only, I'd be doing as circuits2 suggests - use a list box or a data grid.

If you really want to use a combo, you could assign the index of the combo that you want to maintain in the SelectedIndexChanged event:

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
        ComboBox1.SelectedIndex = 2
End Sub

If the user sees an enabled ComboBox they have a right to expect it to allow them to choose an item. If it doesn't then they have a right to assume that your app is broken. If you don't want the user to make a selection and you don't want to disable the ComboBox (how bad is your user's eyesight that they can't read a disabled ComboBox?) then hide it and display a read-only TextBox in its place.

If the data inside the combo box is grab from a database, combobox1.selectedindex=0 or 1 or 2 doesn't seems to get any value

You will need to refer to the index of the item in your datasource. For example, if you want to display data relating to the fourth record in your datasource then set the SelectedIndex to 3.
