回答1:

Use ItemStyle and HeaderStyle and FooterStyle to set Width

<asp:TemplateField HeaderText="Day Id">
                    <ItemTemplate>
                        <asp:Label ID="LblDayId" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "DayId") %>'></asp:Label>
                    </ItemTemplate>
<ItemStyle Width="20px" />
<HeaderStyle  Width="20px" />
 <FooterStyle Width="20px" />                                                   
                    <EditItemTemplate>
                        <asp:Label ID="lblEditDayId" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "DayId") %>'></asp:Label>
                    </EditItemTemplate>
