Question

（我试图将我的麻烦土耳其语翻译成英语。“JavaScriptçalışmazamanıhatası：Tanımsızveyaboşreferansın'value'özelliğiayarlanamıyor”in Turkish。我写这篇文章以便更好地了解我，如果你懂土耳其语）我尝试将选定的gridview行的信息传递给Datalist的ItemTemplate表，代码为

    protected override void Render(System.Web.UI.HtmlTextWriter writer)
    {
        foreach (GridViewRow row in GridViewVehicleList.Rows)
        {
            if (row.RowType == DataControlRowType.DataRow)
            {
                // set the last parameter to true 
                // to register for event validation. 
                row.Attributes["onclick"] =
                 ClientScript.GetPostBackClientHyperlink(GridViewVehicleList,
                    "select$" + row.DataItemIndex, true);
            }
        }
        base.Render(writer);
    }


    protected void OnRowSelected(object sender, GridViewSelectEventArgs e)
    {
        // Get the datakey of the selected row
        var id = Convert.ToInt32(GridViewVehicleList.DataKeys[e.NewSelectedIndex].Value);
        var id2 = Convert.ToInt32(GridViewVehicleList.DataKeys[e.NewSelectedIndex].Values[1]); 

        SqlDataSourceVehicleListForDatalist.SelectCommand = string.Format("SELECT *" +
            " FROM CURRENTDATA WHERE DATEANDTIME = {0} AND RFID = {1}", id,id2 );
        DataListVehicleList.DataBind();

        MultiView1.ActiveViewIndex = 4;
    }

但我犯了上面的错误

如何克服这个问题

全部谢谢

我认为问题在于您从本地资源文件获取对象。可以在code behind中，也可以在JS中。正确检查GetLocalResourceObject("key")字符串是否在资源文件中退出并具有值。

JavaScript运行时错误：无法将Reference的Value属性设置为undefined或null
