每当我在组合框中选择另一个项目时，它都会显示错误的值

Question

我创建了一个组合框，并在加载表单时填充它，并且每当我在组合框中选择一名员工时，它就会运行良好。但是，每当我选择姓氏为“ BAUTISTA”的员工时，我都会得到错误的employeeid。当我查看调试器时，我选择的员工的employeeid为100009，但id的实际值为10008。

 ds = sqlfunction.getTable("SELECT * FROM TABLE")
 With cmb_employee
        .DataSource = ds.Tables(0)
        .ValueMember = "employeeid"
        .DisplayMember = "sname"
 End With


 Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles 
     Button3.Click
    Dim  employee As String

    employee = cmb_employee.SelectedValue.ToString.Trim
    LoadLoans2( employee)
 End Sub

Private Sub LoadLoans2(ByVal type As String, ByVal employee As String, ByVal status As String)
    Dim ds As DataSet
    DataGridView1.DataSource = Nothing

    ds = sqlFunctions.getTable("select * FROM TABLE WHERE employeeid=employeeid AND loanid="THE VALUE THAT I SELECT")
    With DataGridView1
        .AutoGenerateColumns = True
        .DataSource = ds.Tables(0)
    End With
    ds.Dispose()
End Sub

Answer 1

在线ds = sqlFunctions.getTable("select * FROM TABLE WHERE employeeid=employeeid AND loanid="THE VALUE THAT I SELECT")

变化employeeid=employeeid

至employeeid="& employee &"

另一个问题：您的代码提供了Private Sub LoadLoans2(ByVal type As String, ByVal employee As String, ByVal status As String)

但看起来您仅用1个参数调用了另一个子：LoadLoans2( employee)
