我有一个gridview

        <asp:BoundField DataField="UnusedTicketAmount" HeaderText="UnusedTicketAmount" />
        <asp:BoundField DataField="ddlUnusedAmount" HeaderText="ddlUnusedAmount" />
        <asp:BoundField DataField="AirlinePenality" HeaderText="AirlinePenality" />
        <asp:BoundField DataField="ddlAirlinePenality" HeaderText="ddlAirlinePenality" />
        <asp:BoundField DataField="NetRefundProcess" HeaderText="NetRefundProcess" />
        <asp:BoundField DataField="ddlNetRefundProcess" HeaderText="ddlNetRefundProcess" />
        <asp:BoundField DataField="RefundableCommission" HeaderText="RefundableCommission" />
        <asp:BoundField DataField="ddlRefundableCommission" HeaderText="ddlRefundableCommission" />
        <asp:BoundField DataField="CouponRefunded" HeaderText="CouponRefunded" />
        <asp:BoundField DataField="RefundType" HeaderText="RefundType" /> 

在这个gridview中,我想将航空公司和ddlairlinepanelity添加到一个列,我该怎么做才能提前感谢

这是我的代码.aspx.cs页面

public string makequery()
{
    string query = string.Empty;
    if (ddlPortal2.SelectedValue == "Select" && tbFrom.Text == null && tbTo.Text == null && ddlQuery.SelectedValue == "Select")
    {
        query = "SELECT * FROM Form3 and ORDER BY CONVERT(VARCHAR(25), [Datetime], 101) between '" + tbFrom.Text + "' and '" + tbTo.Text + "' DESC";
        return query;
    }
    else if(ddlPortal2.SelectedItem.Text!="Select" && tbFrom.Text!=null && tbTo.Text!=null && ddlQuery.SelectedItem.Text=="Select")
    {
        query = "Select * from Form3 where Portal='" + ddlPortal2.SelectedValue + "' and ORDER BY CONVERT(VARCHAR(25), [Datetime], …

错误很简单,但我无法解决这个问题,希望你们帮助我

这是我的aspx页面代码

 <asp:TreeView ID="PictureTree" runat="server" ShowLines="True">
                    <SelectedNodeStyle Font-Bold="True" />
                    <NodeStyle ImageUrl="~/Images/Folder.jpg" />
                </asp:TreeView>

            </td>
            <td style="width:auto;text-align:center;" valign="top">
                <asp:DataList ID="PicturesInFolder" runat="server" Width="100%" CellPadding="5">
                    <ItemTemplate>
                        <h3><asp:Label runat="server" ID="FileNameLabel" Text='<%# System.IO.Path.GetFilenameWithoutExtension(Eval("Name")) %>'></asp:Label></h3>

                        <asp:Image runat="server" ID="Picture" ImageUrl='<%# PictureTree.SelectedValue & Eval("Name").ToString() %>' />
                        <br /><br />
                    </ItemTemplate>
                    <AlternatingItemStyle BackColor="#E0E0E0" />
                </asp:DataList>
                <asp:Label runat="server" ID="NoPicturesInFolderMessage" Font-Italic="True" Visible="False" EnableViewState="False">
                    There are no pictures in the selected folder...
                </asp:Label>

这是我的.cs代码

private const object VirtualImageRoot = "~/Images/Departments/";


protected void Page_Load(object sender, System.EventArgs e)
{
    // On the first page …

我正在处理已经创建的窗口表单,我必须进一步使用该代码和进程,现在认为该代码在一个地方工作,但它不会在其他地方工作它会给我一个错误消息长度不能小于零

我有GridView一些TemplateField包含TextBox控件的项目。我想在其上添加一个必填字段验证器。这是我的代码：

<asp:TemplateField HeaderText="vid">
    <EditItemTemplate>
         <asp:TextBox ID="txtvid" runat="server" Width="150px"
                            Text='<%# Bind("vid") %>'>
         </asp:TextBox>
    </EditItemTemplate>
    <ItemTemplate>
         <asp:Label 
                   ID="lblvid" runat="server" 
                   Text='<%# Bind("vid") %>'>
         </asp:Label>
    </ItemTemplate>
 </asp:TemplateField>

如何在 上放置必填字段验证器txtvid？
