问题描述

大家好，





我有一个datagrid和item命令我用javascript调用了一个确认窗口。点击ok或取消使用的类的对象给出null引用错误。

Hi All,


I have a datagrid and on item command I have called a confirm window with javascript .and on click of ok or cancel the object of class used gives null reference error.

protected void rgrdSearchSet_ItemCommand(object source, GridCommandEventArgs eventArgs)
{
    if (eventArgs.CommandName == "SearchSet")
    {
        int projectId = Common.Common.CurrentSearchCriteria.ProjectId;
        string Message = SearchDb.CheckTagIdExistenceInSearchSet(searchSetId, projectName);

        if (!string.IsNullOrEmpty(Message))
        {
            string record = string.Empty;

            string radalertscript = "<script language='javascript'>function f(){ radconfirm('Tag Ids utilised in Search Set no more exists ', CheckTagId, 330, 100,null,'EXEGO Confirmation') ; Sys.Application.remove_load(f);}; Sys.Application.add_load(f);</script>";
             Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert", radalertscript);

             eventArgs.Canceled = true;

         }
         else
         {
             Common.Common.CurrentSearchCriteria = WorkFlow.SetSearchSetFilterCriteria(searchSetId, projectName,
                                                                                                                                               Common.Common.UserId,
                                                                                                                                              projectId, batchList, false);
          } 
     } 
}

点击是或否确认按钮
它给出空值参考。
