从字符串转换日期和/或时间时转换失败

Question

I have a gridview and sqldatasource. In my regional settings in cp , date format is set to dd.MM.yyyy .

I have in my gridview a column with type date. In the gridview if I set a value to the cell in format dd.MM.yyyy

 `I get Conversion failed when converting date and/or time from character string`.

But if I type a date in format MM.dd.yyyy it works , but I don't really understand why it happenes? and also If I set dd.MM.yyyy date format , manually in the table, it works.

The column is itemtemplate and the control of the column wasn't edited .

Answer 1

Answer 3

You need to specify the format of date into GridView.

 <asp:BoundField DataField="fieldname" HeaderText="Header text" ReadOnly="True"
                                                        SortExpression="fieldname" HtmlEncode="False" DataFormatString="{0:d}" / >
