Set gridview's column width [duplicate]

问题

I have gridview as follows:

But when i enters any larger with text in it, its column with gets increased as follows:

In this we can see that when i have entered large text English Question column's with has got effected.

I wanted to keep it fix.

For that i added <ItemStyle HorizontalAlign="Left" Width="45%" /> in grid's templatefield

but its not working. I also made wrap="true" for label. but no effect on result.

For more clarity my whole code for grid is as follows:

  <asp:GridView ID="GrdQuestions" runat="server" AllowPaging="True" AutoGenerateColumns="False"
                        CssClass="NormalText" PageSize="100" Width="100%">
                        <HeaderStyle CssClass="TableHeadingNormal TableAlt2" HorizontalAlign="Center" />
                        <RowStyle CssClass="AltColor21" />
                        <AlternatingRowStyle CssClass="AltColor22" />
                        <Columns>
                            <asp:TemplateField HeaderText="SrNo" HeaderStyle-HorizontalAlign="Center">
                                <ItemTemplate>
