Question

任何人都可以告诉我我错过了为什么我的行编辑事件没有解雇。我试图在同一网格中提供编辑工具以及添加新数据。我能够添加新数据（新行），但无法编辑现有行以进行更新。我的行编辑事件没有触发。

我代码背后的代码就是这个事件没有触发。我错了

   protected void grdHierarchy_RowEditing(object sender, GridViewEditEventArgs e)
    {
        grdHierarchy.EditIndex = e.NewEditIndex;
        grdHierarchy.ShowFooter = false;
    }

   protected void grdHierarchy_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName.Equals("New"))
        {
            Hierarchy Hierarchy = new Hierarchy();
            TextBox txtHierarchyName = (TextBox)grdHierarchy.FooterRow.FindControl("txtHierarchyName");
            DropDownList ddlLevelName = (DropDownList)grdHierarchy.FooterRow.FindControl("ddlLevelName");
            string HierarchyName = txtHierarchyName.Text.Trim();
            bool IsNameExist = Hierarchy.IsNameExist(Session, HierarchyName);
            if (IsNameExist == false)
            {
                Hierarchy.Id = 0;
                Hierarchy.Name = HierarchyName;
                Hierarchy.LevelId = Convert.ToInt64(ddlLevelName.SelectedValue);
                Hierarchy.CreatedDtTm = DateTime.Now;
                Hierarchy.ModifiedDtTm = DateTime.Now;
                Hierarchy.Save(Session);
                fillHierarchyGrid();
            }
            else
            {
                cGlobalUI.showPopupMsg(Page, "Hierarchy Name is already Exist", cGlobalUI.MessageType.mtInformation);
            }
        }
    }

Gridview行编辑无效
