Question

i 只是注意到,如果删除<代码>和>;掌握:更新......<>/代码>,则发出警报信息。

我的守则是,如何提醒人们注意由密码背后发出的信息,我已经尝试过一些方法,但我从未发出警报。

protected void gv_RowCommand(object sender, GridViewCommandEventArgs e)
{
  if (e.CommandName == CRUID.Delete.ToString())
  {

  ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alert", "alert( Deleted successfully! );", true);

or

// Define the name and type of the client scripts on the page.
         String csname1 = "PopupScript";
         Type cstype = this.GetType();

         // Get a ClientScriptManager reference from the Page class.
         ClientScriptManager cs = Page.ClientScript;

         // Check to see if the startup script is already registered.
         if (!cs.IsStartupScriptRegistered(cstype, csname1))
         {
             StringBuilder cstext1 = new StringBuilder();
             cstext1.Append("<script type=text/javascript> alert( Hello World! ) </");
             cstext1.Append("script>");

             cs.RegisterStartupScript(cstype, csname1, cstext1.ToString());
         }
   }
}

protected override void Page_Load(object sender, EventArgs e)
{
   gv.DataSourceID = "gvDataSource";
}

ps: iam using objectdatasource to bind my gridview control

尝试改变:

ScriptManager.RegisterClientScriptBlock(this.Page, this.Page.GetType(), "alert", "alert( Deleted successfully! );", true);
