C# 需要在radbutton eventargs中添加TreeListCommandEventArgs protectedvoid RadButton1\u单击（对象发送方，事件参数e） { RadTreeList1.itemcond-=新事件处理程序（RadTreeList1\u itemcond）； RadButton radbutton1=（RadButton）Form.FindControl（“radbutton1”）； TreeListDataItem=e.项作为TreeListDataItem； Hashtable=新的Hashtable（）； 表[“RowId”]=（dataItem.FindControl（“Label1”）作为标签）； 表[“别名”]=（dataItem.FindControl（“Label2”）作为标签）； }

由于radbutton中没有

TreeListCommandEventArgs

，因此我在项目中遇到错误，请帮助我解决此问题
如果我将

EventArgs

替换为

TreeListCommandEventArgs

，这并不意味着无效，并且在运行时成为错误…

受保护的无效RadButton1\u单击（对象发送方，EventArgs e）
protected void RadButton1_Click(object sender, EventArgs e)
    {

        RadTreeList1.ItemCommand -= new EventHandler<TreeListCommandEventArgs>(RadTreeList1_ItemCommand);
        RadButton radbutton1 = (RadButton)Form.FindControl("RadButton1");
        TreeListDataItem dataItem = e.Item as TreeListDataItem;
        Hashtable table = new Hashtable();
        table["RowId"] = (dataItem.FindControl("Label1") as Label).Text;
        table["Alias"] = (dataItem.FindControl("Label2") as Label).Text;

    }

{
RadTreeList1.itemcond-=新事件处理程序（RadTreeList1\u itemcond）；
ContentPlaceHolder contentPage=this.Page.Master.FindControl（“ContentPlaceHolder 1”）作为ContentPlaceHolder；
RadButton R=发送器为RadButton；
RadButton radbutton1=R.Parent.FindControl（“radbutton1”）作为RadButton；
CommandEventArgs e2=新CommandEventArgs（null，radbutton1.CommandArgument）；
TreeListCommandEventArgs e1=新的TreeListCommandEventArgs（null，radbutton1.CommandArgument，e2）；
TreeListDataItem=e1。项作为TreeListDataItem；
Hashtable=新的Hashtable（）；
表[“RowId”]=（dataItem.FindControl（“Label1”）作为标签）；
表[“别名”]=（dataItem.FindControl（“Label2”）作为标签）；
}

fR从这里我可以添加TreeListCommandEventArgs…仍然有一个例外…那就是我无法找到RadTreeList中的控件RadButton1…在这里你可以找到RadButton1

 protected void RadButton1_Click(object sender, EventArgs e)
        {


            ContentPlaceHolder contentPage = Page.Master.FindControl("ContentPlaceHolder2") as ContentPlaceHolder;
            RadButton radbutton1 = (RadButton)contentPage.FindControl("RadButton1");
            object mysender = (object)radbutton1;
            CommandEventArgs e2 = new CommandEventArgs(null, radbutton1.CommandArgument);
            RadButton1_Click(mysender, e2);
            TreeListCommandEventArgs e1 = new TreeListCommandEventArgs(null,radbutton1.CommandArgument,e2);
            TreeListDataItem dataItem = e1.Item as TreeListDataItem;
            Hashtable table = new Hashtable();
            table["RowId"] = (dataItem.FindControl("Label1") as Label).Text;
            table["Alias"] = (dataItem.FindControl("Label2") as Label).Text;

        }

protected void RadButton1_Click(object sender, EventArgs e)
{
    RadTreeList1.ItemCommand -= new EventHandler<TreeListCommandEventArgs>(RadTreeList1_ItemCommand);

    ContentPlaceHolder contentPage = this.Page.Master.FindControl("ContentPlaceHolder1") as ContentPlaceHolder;
    RadButton R = sender as RadButton;
    RadButton radbutton1 = R.Parent.FindControl("RadButton1") as RadButton;
    CommandEventArgs e2 = new CommandEventArgs(null, radbutton1.CommandArgument);
    TreeListCommandEventArgs e1 = new TreeListCommandEventArgs(null, radbutton1.CommandArgument, e2);
    TreeListDataItem dataItem = e1.Item as TreeListDataItem;
    Hashtable table = new Hashtable();
    table["RowId"] = (dataItem.FindControl("Label1") as Label).Text;
    table["Alias"] = (dataItem.FindControl("Label2") as Label).Text;
}
