ASP.NET GridView中如何用C#来创建模版列

Question

ASP.NET GridView中如何用C#来创建模版列？比如如何在GridView中用代码添加一个Button <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" 
                Width="453px">
            <Columns>
                <asp:BoundField DataField="id" HeaderText="id" />
                <asp:BoundField DataField="name" HeaderText="name" />
                <asp:BoundField DataField="age" HeaderText="age" />
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="UP" />
                        <asp:Button ID="Button2" runat="server" onclick="Button2_Click" Text="Down" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

Answer 1

类似
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="newsID,Us_ID"
        DataSourceID="jianweinews" ShowHeader="False" Width="189px" GridLines="None" EmptyDataText="还没有数据" >
        <Columns>
        <asp:TemplateField   ItemStyle-CssClass="hawk110" >
        <ItemTemplate >
         <asp:HyperLink ID=hyperlink runat="server" NavigateUrl=<%# "~/index/infopublishnews.aspx?newsID="+Eval("newsID")%>>传送</asp:HyperLink>
        </ItemTemplate>
        </asp:TemplateField>
        </Columns>
        <SelectedRowStyle BorderStyle="None" />
    </asp:GridView>如果Eval("newsID")不会绑定的话就直接赋予给GridView 的一个数据源 数据源中包含newsID列。第二种 自己设置NavigateUrl
<asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False" 
            onrowdatabound="GridView3_RowDataBound" >
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:HyperLink ID="HyperLink1" runat="server"><%#Eval("Name") %></asp:HyperLink>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
        </asp:GridView>
后台
protected void GridView3_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        string[] url = { "1.aspx", "2.aspx", "3.aspx" };
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            HyperLink hl = e.Row.FindControl("HyperLink1") as HyperLink;
            hl.NavigateUrl = url[e.Row.RowIndex];//这里超链接只是例子，具体设置为什么在自己修改
        }
    }

我要的是纯代码的，比如下面的例子，我要代码实现。而非手动实现。BoundField mBoundField = new BoundField();
mBoundField.HeaderText = mRow["FieldText"].ToString();
//绑定数据字段
mBoundField.DataField = mRow["FieldName"].ToString();
this.GridViewData.Columns.Add(mBoundField);

我要的是纯代码的，比如下面的例子，我要代码实现。而非手动实现。代码动态添加模版列，请各位帮忙。BoundField mBoundField = new BoundField();
mBoundField.HeaderText = mRow["FieldText"].ToString();
//绑定数据字段
mBoundField.DataField = mRow["FieldName"].ToString();
this.GridViewData.Columns.Add(mBoundField);
