Question

2008，我希望将txtEmpNo绑定到txtFullName。但我查了一下这是正确的。

错误“无法绑定到DataSource上的属性或列[名字]。参数名称：dataMember”

此代码：

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim da3 As New SqlDataAdapter
            Dim ds3 As New DataSet()
            Dim bs2 As New BindingSource()

            Dim sql As String = "SELECT Employee.[First Name] From Employee WHERE Employee.EmployeeNo = '" & txtEmpNo.Text.ToString & "'"
            da3 = New SqlDataAdapter(sql, Conn)
            da3.Fill(ds3, "Employee")

            If ds3.Tables("Employee").Rows.Count > 0 Then
                txtFullName.DataBindings.Add(New Binding("Text", ds3, "Employee.[First Name]"))
                txtFullName.DataBindings.Clear()
            Else
                txtFullName.Text = ""
            End If
End Sub

感谢您的时间。

dataMember参数（第3个）应该只是列的名称应该在第二个参数中传递DataSet中的正确表。换句话说，将绑定更改为：

txtFullName.DataBindings.Add(New Binding("Text", ds3.Tables("Employee"), "First Name"))

如何在Vb.net中将Textbox1绑定到Textbox2
