Question

比如说gridview 中列的控制   使一列能够根据另一列的值来动态显示内容文件名    信息

bb       有文件

Answer 1

嵌套.protected void parent_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            //判断类型是Item或者是间隔Item
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                DataList list = e.Item.FindControl("child") as DataList;//FindControl方法.
                DataRowView drv = e.Item.DataItem as DataRowView;//数据视图
                //根据父层的数据视图,设定子层的数据源.
                DataTable table = t_2.type_2list(int.Parse(drv["typeid_1"].ToString()), "");
                list.DataSource = table.DefaultView;
                list.DataBind();
            }
        }这里我用的是Repeater嵌套.你可以改成GridView

 <asp:GridView ID="grvMapAssociateInfo" runat="server" CssClass="List" AutoGenerateColumns="false" Width="100%" CellPadding="0" CellSpacing="1" BorderWidth="0" OnRowCommand="grvAssociateInfo_RowCommand">
                 <HeaderStyle CssClass="ListHead" HorizontalAlign="Center" />
                <AlternatingRowStyle CssClass="ListTr2" />
                <RowStyle CssClass="ListTr1" />
               <Columns>
                    <asp:BoundField HeaderText="读卡器编号" DataField="ReaderID">
                        <ItemStyle HorizontalAlign="Left" Width="80px" />
                    </asp:BoundField>
                   
                    <asp:BoundField HeaderText="文件名" DataField="FileName" >
                        <ItemStyle HorizontalAlign="Left" Width="80px" />
                    </asp:BoundField>
                    
                    
                    <asp:TemplateField HeaderText="关联信息">
                            <ItemStyle HorizontalAlign="Center" Width="200px"/>
                             <ItemTemplate>
                                 <asp:Label ID="Label1" runat="server" ><%#(DataBinder.Eval(Container,"FileName").ToString())!= " "?"有文件":"无文件" %></asp:Label>
                             </ItemTemplate>                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="操作">
                            <ItemStyle HorizontalAlign="Center" Width="200px"/>
                             <ItemTemplate>
                                 <asp:LinkButton ID="lblDel" runat="server" CommandName="Associate" CommandArgument='<%#Eval("ReaderID") %>'>关联</asp:LinkButton>
                             </ItemTemplate>
                        </asp:TemplateField>
                </Columns>
            </asp:GridView>  不行啊？？

Answer 4

同意楼上
<asp:TemplateField HeaderText="关联信息"> 
    <ItemTemplate> 
         <asp:Label ID="Label1" runat="server" Text='<%# Eval(Container,"FileName").ToString()!= "" ? "有文件" : "无文件" %>' />
    </ItemTemplate>                    
</asp:TemplateField>
