Asp.net 试图通过asp:TemplateField将函数式asp:CommandField转换为asp:LinkButton

我想利用

LinkButton

与

CommandField

相比的属性宽度。从单击调用代码隐藏方法时，我收到以下错误消息：

CS0123:与委托匹配的“ViewHandler”没有重载 “System.EventHandler”

GridView定义：

<asp:GridView ID="wc" EmptyDataText="Empty WC table..." runat="server" 
AutoGenerateColumns="False" GridLines="Horizontal" DataKeyNames="WC_ID,PW_ID,R_Qty" 
CssClass="mGrid" PagerStyle-CssClass="pgr" AlternatingRowStyle-CssClass="alt"  
AllowSorting="true" OnSorting="Sorting" AllowPaging="true" PageSize="15" ViewStateMode="Enabled"
OnSelectedIndexChanging="ViewHandler" OnPageIndexChanging="HandlePageIndexChanging" OnRowDataBound="gvRowDataBound"
OnRowEditing="gvRowEditing" OnRowCancelingEdit="gvRowCancelingEdit" OnRowUpdating="gvRowUpdating">

我需要做什么才能使签名与

ViewHandler

方法匹配？我注意到如果我从

GridViewSelectEventArgs

切换到

EventArgs

，过载错误会消失，但是

e.NewSelectedIndex

不存在

谢谢

您的问题是

链接按钮的
OnClick
事件处理程序必须具有以下签名：

protected void LinkButton_Click(Object sender, EventArgs e) 

但你把它定义为

protected void ViewHandler(object sender, GridViewSelectEventArgs e)

但是，显然，您将无法访问e.NewSelectedIndex。您可以做的是将标记更改为（注意
CommandArgument
部分）：

注意：

Prop1、Prop2等。
必须从数据源更改为实际的属性名称
上面的代码还没有经过测试，但这就是想法
我确实知道这件事。。。CommandArguments字符串的构建是错误的，但我可以找到答案-谢谢！
protected void ViewHandler(object sender, GridViewSelectEventArgs e)
    {
        string WC_ID =wc.Rows[e.NewSelectedIndex].Cells[0].Text;
        string PW_ID = wc.Rows[e.NewSelectedIndex].Cells[1].Text;
        string VIN = wc.Rows[e.NewSelectedIndex].Cells[2].Text;
        string PROD = wc.Rows[e.NewSelectedIndex].Cells[3].Text;
        string W = wc.Rows[e.NewSelectedIndex].Cells[4].Text;
