Combo boxes initially highlighted

[Gary Shell]

I have five comboboxes each has a item listed populated by hand in the IDE.
Each has the text property bound to a text field in the database. When I
initially fill the dataset and display the page all of these combo boxes
display the correct data, but all of them are highlighted as if they have
focus.

If I click in on and then click another control the highlight goes away. I
have a tabbed interface and If I navigate to another tab and back the
highlights are gone from all of the combo boxes.

How can I get them to initially display the data not highlighted?

Gary,

They are highlighted because that the 0 index is the selected one initially.

Set the selectedindex to -1 of each after loading and that goes away.

I hope this helps?

Nevertheless, the comboboxes should not remain highlighted if they don't
have the focus.

But all five of them remain highlighted. I tried the suggestion Cor left
but that had no effect.

I'm at a lost to explain how five combo boxes could all appear to have
focus at the same time.

Thanks, I tried that with no effect. This is very strange.

Gary,

Can you explain this sentence a little more, I overreaded it focused on the
focus.

I have five comboboxes each has a item listed populated by hand in the IDE.
Each has the text property bound to a text field in the database.

When you have databind it to the database, than it should show the current
item in the database and not an item that you loaded. And is than a little
bit strange.

I have tried to simulate what you did, however cannot get your behaviour.

Gary,

Can you show how you bind them, just one is enough.

I ask you this because you are so definitly talking about binding while the
normal way is to set the datasource of the combobox to the table of the
dataset and than tell which displaymember (datafield) will be used.

When you do that and you use the index_change event from the comboboxes.
Than do you have to protect that it is firing in advance. The most used
method is a startupswitch (bool), which is set to true as soon as the
datasource and members of the comboboxes are set.

I hope this helps?

I only use a datasource and displaymember (and usually valuemember) if I
want the drop down list portion of the combo box to be populated from a
database, but that is not what I am doing in this instance at all so all
three of those are set to nothing.

As I have said, my drop down list is populated by way of the Items
collection in the VB.NET IDE. I just typed in the four possible allowed
values there. Under the databindings properties I have the text property
bound to my field in the database.

Here is the generated code from the form designer:

'cmbPartner
Me.cmbPartner.A nchor = CType(((System. Windows.Forms.A nchorStyles.Bot tom Or
System.Windows. Forms.AnchorSty les.Left) _Or
System.Windows. Forms.AnchorSty les.Right), System.Windows. Forms.AnchorSty les)
Me.cmbPartner.D ataBindings.Add (New System.Windows. Forms.Binding(" Text",
Me.datasetLocSc enario, "Scenario_to_Lo cation.PartnerT ype"))
Me.cmbPartner.I temHeight = 13
Me.cmbPartner.I tems.AddRange(N ew Object() {"", "Customer", "Supplier",
"Lead"})
Me.cmbPartner.L ocation = New System.Drawing. Point(568, 302)
Me.cmbPartner.N ame = "cmbPartner "
Me.cmbPartner.S ize = New System.Drawing. Size(176, 21)
Me.cmbPartner.T abIndex = 52

Gary,

It was the code I expected (exactly as you described) however what would it
do in your opinion.
(And therefore I asked you to show it, because I could misunderstand you).

The databinding is to set the text from the dataadapter field to the same
text in the combobox as is the currentposition in the datatable to what it
is binded. However that dataset has now in my opinion no way to change its
position.

What is your purpose now?

I'm sorry Cor, but I just do not follow this second paragraph at all.

The code works as I expect it to. That is, the form displays with data from
my dataset. I can pick an item from the drop down list and the dataset is
updated.

Changing position of the dataset is outside the scope of this question. My
application uses a tree to pick what record is displayed on this form. When
I close the form the dataset changes (if any) are written back to the
database.
The user picks another item from the tree and a new instance of my form pops
up.

None of this is the issue, though. The issue remains, with this code all
the combo boxes are initially highlighted.
