Symptoms: when GridView binds the date format, the date in the database is 2008-07-04, while GridView displays 2007-07-04 000000. , Solution: if you want to get rid of the extra zeros, just add a sentence to the source code in the first column of the binding time, as shown in red below

<asp:BoundField DataField="BeginDate" HeaderText=" The start time "
DataFormatString="{0:d}" htmlencode="false"
HeaderStyle-HorizontalAlign="Center"
ItemStyle-HorizontalAlign="Center" >
