ASP.NET中GridView控件开发问题：无法触发GridView1_RowCommand(object sender, GridViewCommandEventArgs e)方法

Question

delete的 CommandName就用Delete好了，不要用MyDelete

Answer 1

我更改了*.aspx,*.cs中的MyDelete为Delete可是还是无法触发GridView1_RowCommand？？？？？？？？？？？？？ 

Answer 2

直接在GirdView里面双击删除
添加删除事件
事件空的也没关系
这样应该就好了

Answer 3

你可以EnableEventValidation 设置为true，然后将你的所有关于GRIDVIEW的数据绑定操作都放倒Page.IsPostBack = true 的条件下。

Answer 4

先看基础概念：
http://www.google.com.hk/search?hl=zh-CN&lr=lang_zh-CN%7Clang_zh-TW&newwindow=1&safe=strict&rlz=1I7GGLD_zh-CN&biw=1366&bih=712&tbs=lr%3Alang_1zh-CN%7Clang_1zh-TW&q=asp.net+bubbleevent&oq=asp.net+bubbleevent&aq=f&aqi=&aql=&gs_l=serp.3...9176.9697.0.10241.5.4.0.0.0.0.0.0..0.0...0.0..0.IVXDgEezVtE然后看看GridView是怎么写的：protected override bool OnBubbleEvent(object source, EventArgs e)
{
    bool causesValidation = false;
    string validationGroup = string.Empty;
    GridViewCommandEventArgs args = e as GridViewCommandEventArgs;
    if (args != null)
    {
        IButtonControl commandSource = args.CommandSource as IButtonControl;
        if (commandSource != null)
        {
            causesValidation = commandSource.CausesValidation;
            validationGroup = commandSource.ValidationGroup;
        }
    }
    return this.HandleEvent(e, causesValidation, validationGroup);
}private bool HandleEvent(EventArgs e, bool causesValidation, string validationGroup)
{
    bool flag = false;
    this._modelValidationGroup = null;
    if (causesValidation)
    {
        this.Page.Validate(validationGroup);
        if (this.EnableModelValidation)
        {
            this._modelValidationGroup = validationGroup;
        }
    }
    GridViewCommandEventArgs args = e as GridViewCommandEventArgs;
    if (args != null)
    {
        this.OnRowCommand(args);
        flag = true;
        string commandName = args.CommandName;
        if (StringUtil.EqualsIgnoreCase(commandName, "Select"))
        {
            this.HandleSelect(this.GetRowIndex(args.Row, (string) args.CommandArgument));
            return flag;
        }
        if (StringUtil.EqualsIgnoreCase(commandName, "Page"))
        {
            string commandArgument = (string) args.CommandArgument;
            int pageIndex = this.PageIndex;
            if (StringUtil.EqualsIgnoreCase(commandArgument, "Next"))
            {
                pageIndex++;
            }
            else if (StringUtil.EqualsIgnoreCase(commandArgument, "Prev"))
            {
                pageIndex--;
            }
            else if (StringUtil.EqualsIgnoreCase(commandArgument, "First"))
            {
                pageIndex = 0;
            }
            else if (StringUtil.EqualsIgnoreCase(commandArgument, "Last"))
            {
                pageIndex = this.PageCount - 1;
            }
            else
            {
                pageIndex = Convert.ToInt32(commandArgument, CultureInfo.InvariantCulture) - 1;
            }
            this.HandlePage(pageIndex);
            return flag;
        }
        if (StringUtil.EqualsIgnoreCase(commandName, "Sort"))
        {
            this.HandleSort((string) args.CommandArgument);
            return flag;
        }
        if (StringUtil.EqualsIgnoreCase(commandName, "Edit"))
        {
            this.HandleEdit(this.GetRowIndex(args.Row, (string) args.CommandArgument));
            return flag;
        }
        if (StringUtil.EqualsIgnoreCase(commandName, "Update"))
        {
            this.HandleUpdate(args.Row, this.GetRowIndex(args.Row, (string) args.CommandArgument), causesValidation);
            return flag;
        }
        if (StringUtil.EqualsIgnoreCase(commandName, "Cancel"))
        {
            this.HandleCancel(this.GetRowIndex(args.Row, (string) args.CommandArgument));
            return flag;
        }
        if (StringUtil.EqualsIgnoreCase(commandName, "Delete"))
        {
            this.HandleDelete(args.Row, this.GetRowIndex(args.Row, (string) args.CommandArgument));
        }
    }
    return flag;
}
也就是说,你的事件第二个参数EventArgs必须是GridViewCommandEventArgs或者IButtonControl。
