I m using the following code to save the date from a textbox and selecting the date using date picker.
我使用以下代码从文本框中保存日期并使用日期选择器选择日期。
If (String.IsNullOrEmpty(DobTxt.Text)) Then
SQLCmd.Parameters.Add("@DOB", SqlDbType.Date).Value = DBNull.Value
Else
Dim DOBDte As date= String.Format("{0:YYYY-MM-dd}", DobTxt.Text.Trim())
SQLCmd.Parameters.Add("@DOB", SqlDbType.Date).Value = DOBDte
End If
Now the code works just fine with dates like ""
现在代码在日期"
but when you go for a date like "10/01/2016" I get this error:
但是当你去约会的时候,比如“10/01/2016”,我就会犯这样的错误:
Conversion from string "10/30/2016" to type 'Date' is not valid
将字符串“10/30/2016”转换为类型“Date”无效
could you please help

ElseIf Date.TryParse(DobTxt.Text.Trim(), dateValue) Then
SQLCmd.Parameters.Add("@DOB", SqlDbType.Date).Value = dateValue

If you're using jQuery date picker, and your date format is not mm-dd-yy you should configure datepicker to that format:
如果您使用的是jQuery日期选择器,并且您的日期格式不是mm-dd-yy,您应该将datepicker配置为该格式:
$( ".selector" ).datepicker({
dateFormat: "yy-mm-dd"
});
