从datetimepicker控件更改日期时过滤日期？ [英] filter date while changing the date from datetimepicker control?

问题描述

你好，

我在dataGridview中从MS Access数据库中获取数据。

Am fetching the data from MS Access database in dataGridview.

我有一个按钮来加载数据之后，我想从datetimepicker中选择日期，在选择时，它应根据gridview中的选择显示所有记录。我试过这段代码...

I have one button to load the data in table after that I want to select the date from datetimepicker and on selection it should dispaly all the records based on the selection in gridview.I tried this code...

private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
        {
             DataView dv = new DataView(dt);
           
            DateTime startT = new DateTime();
            DateTime endT = new DateTime();
            startT = dateTimePicker1.Value.Date; // Ex: 2014-11-24 12:00:00
            endT = dateTimePicker1.Value.Date.AddDays(1).AddSeconds(-1); // Ex: 2014-11-24 11:59:59
           // dv.RowFilter = string.Format("Select * From CustomerDetails WHERE DATA Between '" + startT + "' AND '" + endT + "'");
            dv.RowFilter = string.Format("BookingDate  '%{0}%'",  dateTimePicker1.Value.ToString());
            dataGridView2.DataSource = dv;
          //bindingSource1.Filter = string.Format("EventDate = #{0}#",dateTimePicker1.Value.ToLongDateString());
        }

谢谢，

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:

#DataView RowFillter like operator
