Format DateTime in BoundField Column of ASP.Net GridView

This Way:

This is for BoundField

<asp:BoundField DataField="ModifiedDate" 
                    HeaderText="ModifiedDate" 
                    SortExpression="ModifiedDate" 
                    DataFormatString="{0:d}" />
<asp:BoundField   
            DataField="BirthDate"   
            DataFormatString="{0:ddd MM, yyyy}"   
            HtmlEncode="false"  
            HeaderText="ddd MM, yyyy" />

This Is for label

<asp:Label id="Label1" runat="server" Text='<%# Eval("CreationDate", "{0:M-dd-yyyy}") %>'>
    </asp:Label>
