我有这个代码用于搜索记录。对于那个网格，我添加了页面索引，但它没有正确显示。当点击搜索按钮时，它显示更多的n个记录，当时页面索引不起作用。它在点击搜索按钮之前调用第一个网格。如何更改我的代码请帮助我.....

试试这个......

    private void grid()
   {
      if(!string.IsNullOrEmpty(yourSearchTextBox.Text)
      {
      // Then call search method. Make sure you bind the Grid in that method.
      }
      else
      {
      // Normally Bind the Grid as you are already doing in this method.
      }
   }

你必须检查那个grid（）方法中是否有任何搜索文本，如...
