Problems with Bound Combobox VS.NET - Cannot select item

I have a bound combobox on a form. The combobox is populated from another table. Here is code for populating:

I have tried both this:
==================================================
Dim dvClients as new Dataview(me.fEdge_Dataset.tblOrganization)
me.ccClientInfoCombobox.DataSource = dvClients
me.ccClientInfoCombobox.DisplayMember = "pkOrganizationID"
me.ccClientInfoCombobox.ValueMember = "OrganizationOwnerName"

and this:
==================================================
        Me.CcClientInfoComboBox.DataBindings.Add(New System.Windows.Forms.Binding("Text",  Me.Gen_AppraisalMainBindingSource1, "ccClientInfo", True))
        Me.CcClientInfoComboBox.DataBindings.Add(New System.Windows.Forms.Binding("SelectedValue",  Me.Gen_AppraisalMainBindingSource, "ccClientInfo", True))
        Me.CcClientInfoComboBox.DataSource = Me.TblOrganizationBindingSource
        Me.CcClientInfoComboBox.DisplayMember = "OrganizationOwnerName"
        Me.CcClientInfoComboBox.ValueMember = "pkOrganizationId"

pkOrganizationalID is an identity number.
Organizationownername is a text value.

The box populates with no problem. I can select a value with no problem. I then cannot leave the combobox.

If I type in a numeric value in the box, I can leave the combobox and populate others. Alternately, if I change the display member to the ID value in my code, I can select a value and leave the box.

This has me baffled. Any help at all is appreciated.

A time saver rule of thumb I have come up, working with microsoft products, is...
When I face peculiar behavior with controls, the first thing I do, is DELETE the control, save the form, close my App and re-open it again. THEN I create another control and if possible (few ajustments in my code) I give it another name...

I have deleted and recreated it more times than I can count. I followed your exact instructions and still the same result. There MUST be something I am doing wrong, but can't figure it.

Ok.
From the built menu
click ->Clean Solution

->RE-building solution (not built)

I hope I am not waisting your time, bacause I find no reasoning in the error you get. The code looks ok.

Yeah... I have cleaned many many times.
I found the solution.

There is another person who had this issue: here is the link on EE.
http://www.experts-exchange.com/Programming/Languages/.NET/Visual_Basic.NET/Q_21724117.html?sfQueryTermInfo=1+bound+combobox

The way I fixed it is I manually went into the databindings for the combobox, and made sure that all databindings were set to "none". Then I manually selected the "Selected value" for the item in the ds that I wanted. For whatever reason.... it worked. And is working now. Thanks for your help and assistance. D**N those stupid MS gizmos.
