老师好，
请教一下，希望在选择不同的表行后，根据表行的内容，对窗口按钮的背景色进行赋值，现在只有第一次选择行后有效果，重新选择不同行后，没效果，请教一下，代码要怎么改，谢谢！
For Each dr1 As DataRow In DataTables("表B").DataRows
If dr1("第二列") = "进行中" Then
Forms("窗口1").Controls("Button2").BackColor = Color.blue
Forms("窗口1").Controls("Button1").BackColor = Color.blue
ElseIf dr1("第二列") = "异常" Then
Forms("窗口1").Controls("Button2").BackColor = Color.red
Forms("窗口1").Controls("Button1").BackColor = Color.red
ElseIf dr1("第二列") = "完成" Then
Forms("窗口1").Controls("Button2").BackColor = Color.Green
Forms("窗口1").Controls("Button1").BackColor = Color.Green
ElseIf dr1("第二列") = "暂停" Then
Forms("窗口1").Controls("Button2").BackColor = Color.Yellow
Forms("窗口1").Controls("Button1").BackColor = Color.Yellow
Else
If dr1("第二列") = "待开始" Then
Forms("窗口1").Controls("Button2").BackColor = Color.Silver
Forms("窗口1").Controls("Button1").BackColor = Color.Silver
End If
End If
Next
谢谢！
