我有以下代码.我没有在gridview中定义任何边界字段.我正在使用我的aspx.cs文件中的sql查询来检索数据.是否可以调整每列0,1,2的宽度？我有什么办法可以研究吗？我尝试了很多方法,但它仍然无法正常工作.请帮忙!

<asp:GridView ID="surgicalGridView" runat="server"
    CaptionAlign="Top" HorizontalAlign="Justify" 
    DataKeyNames="id" onselectedindexchanged="surgicalGridView_SelectedIndexChanged"
    ToolTip="Excel File Download Tool" CellPadding="4" ForeColor="#333333" 
    GridLines="None" Width="854px">

     <RowStyle BackColor="#E3EAEB" />
       <Columns>
       <asp:CommandField ShowSelectButton="True" SelectText="Download" 
               ControlStyle-ForeColor="Blue">
<ControlStyle ForeColor="Blue"></ControlStyle>
           </asp:CommandField>
       </Columns>
     <FooterStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
     <PagerStyle BackColor="#666666" ForeColor="White" HorizontalAlign="Center" />
     <SelectedRowStyle BackColor="#C5BBAF" Font-Bold="True" ForeColor="#333333" />
     <HeaderStyle   BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />
     <EditRowStyle BackColor="#7C6F57" />
     <AlternatingRowStyle BackColor="White" />
        <SortedAscendingCellStyle BackColor="#F8FAFA" />
        <SortedAscendingHeaderStyle BackColor="#246B61" />
        <SortedDescendingCellStyle BackColor="#D4DFE1" />
        <SortedDescendingHeaderStyle BackColor="#15524A" />
    </asp:GridView>
    <br />

当OnItemUpdated被解雇时,我不能为我的生活找到答案.我一直在使用ASP.NET来试图学习它,所以你在这段代码中看到的一些东西可能是故意做的(所以我可以更好地理解幕后发生的事情)

基本上,我有一个GridView,它是使用formview作为细节的主控件.

这是SelectedIndexChanged方法GridView

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
    var context = new DataAccessLayer.SafetyEntities();
    var se = (from c in context.Employees
                  where c.EID == (long)GridView1.SelectedDataKey.Value
                  select c).ToList();
    FormView1.DataSource = se;
    FormView1.DataKeyNames = new string[] { "EID" };
    FormView1.DataBind();
}

这样工作正常,它会在表单中显示所选的详细信息以进行编辑.这是formview看起来像:

<asp:FormView ID="FormView1" runat="server" DefaultMode="Edit" OnItemUpdating = "FormView1_ItemUpdating" OnItemUpdated="BLAH">
    <ItemTemplate>
        Select an employee!
     </ItemTemplate>
     <EditItemTemplate>
         <table>
             <tr>
                 <th>Name: 
                 </th>
                    <td>
                        <asp:TextBox runat="server" ID ="NameEdit" Text='<%#Bind("Name") %>' /> 
                    </td>
                    <br />
            </tr>
            <tr>
                <th>Manager: 
                </th>
                <td> …
