Answer 1

最好复制下来用文本看，这是datagrid的

Answer 2

没有数据是因为你没有绑定数据源;
要放入控件的话,设置几个模板列,然后Gridview上右键->编辑模板->你要编辑的模板
直接拖控件进去好了

Answer 3

不是没有数据的问题 我现在的问题是在页面上不显示Gridview的表格形式 正常的话 就算没有数据在运行的时候 不也得有空表格出现 对吧 最起码有标题出现 现在是什么都没有! 这个问题实现了 然后解决数据绑定的问题！

Answer 4

用的是VS 2005上面没有Datagrid的控件了！ 郁闷 不过还是谢谢大家  要是谁有的网站介绍也行 谢谢你们！

Answer 5

我正在用gridview 这事VS2005自动生成的前台代码：  <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" GridLines="None" Width="710px" >
            <Columns>
                <asp:BoundField DataField="product_id" HeaderText="ID" SortExpression="product_id" />
                <asp:BoundField DataField="product_name" HeaderText="产品名称" >
                    <ItemStyle HorizontalAlign="Center" Width="100px" />
                </asp:BoundField>
                <asp:BoundField DataField="product_price" HeaderText="产品价格" SortExpression="product_price" />
                <asp:BoundField DataField="product_description" HeaderText="产品描述" SortExpression="product_description" />
                <asp:BoundField DataField="product_supplier_id" HeaderText="供应商编号" SortExpression="produc _supplier_id" />
                <asp:BoundField DataField="product_quantity" HeaderText="数量" SortExpression="product_stock_id" />
                <asp:BoundField DataField="product_on_sale" HeaderText="是否有售" SortExpression="product_on_sale" />
                <asp:TemplateField HeaderText="操作 ">
                    <ItemTemplate>
                        <a onclick='js_del(<%# DataBinder.Eval(Container,"DataItem.product_id") %>)'>删除</a>
                        <a onclick='js_edit(<%# DataBinder.Eval(Container,"DataItem.product_id") %>)'>修改 </a>
                    </ItemTemplate>
                </asp:TemplateField>
               
            </Columns>
            <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
            <EditRowStyle BackColor="#999999" />
            <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
            <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
            <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
        </asp:GridView>
后台代码：protected void Page_Load(object sender, EventArgs e)
    {　　//第一次执行加载的代码
        if (!IsPostBack)
        {
            int _id = Convert.ToInt32(Request["id"]);
            _txt_id.Text = _id.ToString();            _min.Text = "";
            _max.Text = "";            Product.BLL.Product _bp = new Product.BLL.Product();
            string _ret = "";
            if (PubLib.Oxox.ConvertToDecimal(_min.Text.ToString()) == PubLib.Oxox.ConvertToDecimal(_max.Text.ToString())) { GridView1.DataSource = _bp.GetList(TextBox1.Text.ToString(), _pd.Text.ToString(), ref _ret); }
            else GridView1.DataSource = _bp.GetList(TextBox1.Text.ToString(), PubLib.Oxox.ConvertToDecimal(_min.Text.ToString()), PubLib.Oxox.ConvertToDecimal(_max.Text), _pd.Text.ToString(), ref _ret);
            GridView1.DataBind();
           
        }
"把其中的一列变成DropDownList那种形式也就是带有下拉栏的形式 其中的两列变成CheckBox"这样:把你选定的列改为模板列,从工具箱托一个DropDownList或者Checkbox                    前台代码:<%# xxx(DataBinder.Eval(Container.DataItem,"字段名").ToString())%>
后台代码:private xxx (object params){ //todo}

Answer 6

现在还是那个问题 数据传上去了 可就是在网页上不显示 不是不显示数据 就是整个gridview控件的表格形式都不显示 我快疯了 代码不是写在MultiView里吗 为什么会出现这样的问题呢 真奇怪 看来今晚上得很晚回家了！大家帮帮我吧

谢谢你楼上！ 你帮我看看 这只是最初期的想要得画面！ 可是运行的时候就是显示不出来 只显示上面的部分！

Answer 9

我记得是如果没有数据的话就会什么都不会显示，包括已经绑定了的字段名也不会显示。我是菜鸟````说的不对，不要介意。随便问个问题，为什么2005没有DATAGRID？？？？？？？

Answer 10

没有数据绑定吧，肯定gridview不会显示出来的
或者你可以手动添加一空行，你改成vb的就行
if (!IsPostBack)
        {
            DataTable dt = new DataTable();
            dt.Rows.Add(dt.NewRow());
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }

Answer 11

没有数据绑定就显示不出来数据哈 那么就在我原先的代码上 手动加一条数据 试试看，呵呵 别改成VB 还是用Asp.Net 该怎么手动加呢 谢谢楼上 嘿嘿！

Answer 12

你应该看看它的属性生成器,还有数据绑定到grideview并且执行了才能显示

Answer 13

用的是VS 2005上面没有Datagrid的控件了！ 郁闷 不过还是谢谢大家  要是谁有的网站介绍也行 谢谢你们！
--------------------------------------------------------------
没有显示出来，但支持，你在里面写 <asp:Datagrid ...一样的

Answer 14

问大家一个白痴的问题哈，从数据源导出的数据想显示在gridview中，现在 gridview其中有一列设置成DropDownList属性，这样的话 （其他的都是BoundField属性的）从数据源导出的数据可以直接显示到设置成DropDownList属性的这一列吗？ 会不会出错！因为我现在还没有数据源 所以不能做例子 所以担心这个问题 谢谢大家帮我 祝你们开心！

        </asp:GridView>这段代码实现了我在gridview里其中的三列设置成checkbox和dropdownlist类型，我现在还想设置成 TableCell类型，在上面的代码上直接把checkbox改成TableCell为什么不行？该怎么实现呢！谢谢大家帮我 紫色阴影 上面的代码就是你写的 谢谢你！现在这个新问题该怎么解决！

tablecell要有table才行
比如：
        <asp:GridView ID="GridView1" runat="server">
            <EmptyDataTemplate>
                <asp:Table ID="Table1" runat="server">
                    <asp:TableRow>
                        <asp:TableCell></asp:TableCell>
                    </asp:TableRow>
                </asp:Table>
            </EmptyDataTemplate>
        </asp:GridView>
