dropdown list first item is always selected

Dear John,
I use 2 ddl. ddlToProject and ddlsection.
ddltoProject is populated at page load. following is the code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then
Call subFromProject()
If dtProjects.Rows.Count > 0 Then
ddlToProject.DataValueField = "PROJC"
ddlToProject.DataTextField = "PROJECT"
ddlToProject.DataSource = dtProjects
ddlToProject.DataBind()
End If
End If

btnShift.Attributes.Add("onclick", "return confirm('Do you want to shift the machine?')")
End Sub

In selected index change event of ddlToProject, the 2nd ddl i.e. ddlsection is populated.


Protected Sub ddlToProject_SelectedIndexChanged(sender As Object, e As EventArgs)
If ddlToProject.SelectedValue <> "" Then
Call subSection()
End If
End Sub

Then I press a shift button for a update command in sql database.

Now, while debugging I found that the ddlsection value is always reaching as the first item in its list, no matter which section I have selected. Hope I am able to explain the issue clearly.

Thanks for support.
