您好Jparv，

Hi Jparv,

根据您的代码，我认为有两点意见检查。

Based on your code, I think there is two point to check.

1。我建议你查看"dateTimePicker1.Value.ToString（）"的值和"BookingDate"的值，你需要保持它们的格式相同。

1. I suggest you check the value of the "dateTimePicker1.Value.ToString()" and the value of the "BookingDate", you need to keep the format of them the same.

2。对于DataView的RowFilter，您将错误的值传递给RowFilter，似乎您想使用like运算符，您可以参考以下链接：

2. For the RowFilter of the DataView, you passed a wrong value to the RowFilter, it seems that you want to use the like operator, you could refer the link below:
