how to set width for templatefields in gridview in asp.net

Actually it will take the width of controls inside the template field.

Set the control width as the width for template field,
Priority will be given to the Control inside the Template (specified in style)
else
it will take the width specified in Itemstyle/HeaderStyle/FooterStyle (see bellow)

<asp:TemplateField HeaderText="Status" SortExpression="Status">

                            <EditItemTemplate>

                                <asp:DropDownList ID="cmbUserStatus" CssClass="GridEditinglistBox" runat="server"

                                    SelectedIndex='<%# SetSelectedStatusIndex(DataBinder.Eval(Container.DataItem, "Status")) %>'>

                                </asp:DropDownList>

                            </EditItemTemplate>

                            <ItemTemplate>

                                <asp:Label ID="Label2" runat="server" Text='<%# SetStatusText(DataBinder.Eval(Container.DataItem, "Status")) %>'></asp:Label>

                            </ItemTemplate>

                            <FooterTemplate>

                                <asp:DropDownList ID="cmbUserStatus" runat="server" CssClass="GridEditinglistBox">

                                </asp:DropDownList>

                            </FooterTemplate>

                            <HeaderStyle HorizontalAlign="Left" Width="70px" />

                            <ItemStyle HorizontalAlign="Left" Width="70px" />

                            <FooterStyle HorizontalAlign="Left" Width="70px" />

                        </asp:TemplateField>

Hey try to use this (as you are using span you need to set there or instead you can use a label)

<ItemTemplate>

                                            <span style="text-align: center;width:100px ">

                                                <center>

                                                    <%#Eval("VehicleNo") %>

                                            </span></center>

</ItemTemplate>

or

<ItemTemplate>

                                <asp:Label ID="Label1" runat="server" Width="100" Text='<%#Eval("VehicleNo") %>'></asp:Label>

                            </ItemTemplate>
