网页生命周期需要帮助 [英] Webpage life cycle help needed

问题描述

大家好......我对页面生命周期有疑问......至少我认为问题出在哪里。



我有编写了一些代码，使用PagedDataSource动态创建分页按钮。除了一个小问题之外，这一切都按预期工作:-（



有一个标签显示当前页面和总页数..但它只会更新到正确的我第二次点击时的当前页面。任何帮助都会非常感激...（我正试图避开J Query，因为我真的没有多少经验。



这是Draw按钮方法。

  private   void  DrawButtons（）
 {
 Button pagerButtonFirst =  new  Button（）; 
 Button pagerButtonLast =  new  Button（）; 
 
 pagerButtonFirst.Text =   first; 
 pagerButtonFirst.Click + = btnFirst_Click; 
 pagerButtonFirst.CssClass =   PageEnds; 
 
 pnlButtonFirst.Controls.Add（pagerButtonFirst）; 
 
  var  paging =（Paging）Session [Globals.SessionsNames.SessTestimonials]; 
 
  for （ int  i =  0 ; i <  paging.PagedSource.PageCount; i ++）
 {
  var  newButton =  new  Button（）; 
 
 newButton.Text =（i +  1 ）。ToString（）; 
 newButton.Command + = btnSpecfic_Click; 
 newButton.CommandArgument =（i +  1 ）。ToString（）; 
 newButton.CssClass =   PageNumber; 
 pnlButtonPages.Controls.Add（newButton）; 
} 
 
 pagerButtonLast.Text =   last; 
 pagerButtonLast.Click + = btnLast_Click; 
 
 pagerButtonLast.CssClass =   PageEnds; 
 pnlButtonLast.Controls.Add（pagerButtonLast）; 
 
 lblPageInfo.Text =  string  .Format（ 显示{1}的页面{0}。（总项{2}），
 paging.PagedSource.CurrentPageIndex +  1 ，paging.PagedSource.PageCount，
 paging.TotalItems.ToString（））; 
}

Hi all... I have a question about page life cycles... at least that''s where I think the problem lies.

I have written some code to dynamically create paging buttons using a PagedDataSource. It all works as intended apart from one small problem :-(

There is a label showing the current page and total pages.. but it only gets updated to the correct current page when I click for a second time. Any help would be MUCH appreciated... (I''m trying to steer clear of J Query as I really don''t have much experience with it.

This is the Draw buttons method.

private void DrawButtons()
   {
       Button pagerButtonFirst = new Button();
       Button pagerButtonLast = new Button();

       pagerButtonFirst.Text = "first";
       pagerButtonFirst.Click += btnFirst_Click;
       pagerButtonFirst.CssClass = "PageEnds";

       pnlButtonFirst.Controls.Add(pagerButtonFirst);

       var paging = (Paging)Session[Globals.SessionsNames.SessTestimonials];

       for (int i = 0; i < paging.PagedSource.PageCount; i++)
       {
           var newButton = new Button();

           newButton.Text = (i + 1).ToString();
           newButton.Command += btnSpecfic_Click;
           newButton.CommandArgument = (i + 1).ToString();
           newButton.CssClass = "PageNumber";
           pnlButtonPages.Controls.Add(newButton);
       }

       pagerButtonLast.Text = "last";
       pagerButtonLast.Click += btnLast_Click;

       pagerButtonLast.CssClass = "PageEnds";
       pnlButtonLast.Controls.Add(pagerButtonLast);

       lblPageInfo.Text = string.Format("Showing page {0} of {1}. (total items {2})",
                                        paging.PagedSource.CurrentPageIndex + 1, paging.PagedSource.PageCount,
                                        paging.TotalItems.ToString());
   }
