主题：[求助]Comobox SelectedIndexChanged事件

1、你这些TextBox绑定到窗口中这个表的各列了吗？如果没有绑定，自然不会发生变化。

2、你下面这些代码，意义何在？

Dim txt1 As String = e.Form.Controls("TextBox1").Value
Dim txt2 As Double = e.Form.Controls("TextBox2").Value
Dim txt3 As String = e.Form.Controls("TextBox3").Value
Dim txt4 As String = e.Form.Controls("TextBox4").Value
Dim txt5 As String = e.Form.Controls("TextBox5").Value
Dim txt6 As String = e.Form.Controls("TextBox6").Value
Dim txt7 As String = e.Form.Controls("TextBox7").Value
Dim txt8 As String = e.Form.Controls("TextBox8").Value
Dim txt9 As String = e.Form.Controls("TextBox9").Value
Dim txt10 As String = e.Form.Controls("TextBox10").Value

如果你在TextBox对筛选后的数据进行统计，可以：

'原来的筛选代码

e.Form.Controls("TextBox1").Value  = Tables("表名").Compute("Sum([某某列1])")

e.Form.Controls("TextBox2").Value  = Tables("表名").Compute("Sum([某某列2])")
