ExtJs中从一个GridPanel中选择数据到另一个GridPanel中暂时规定被取数据的GridPanel为Grid1，接收数据的GridPanel为Grid2。如果想要Grid2能接收到Grid1的数据的话，就要Grid2在定义column的时候为Grid1的column的子集，也就是定义的列名称要与Grid1的列名称相同。下面附上例子，效果是双击Grid1的一行，将这一行的数据传到Grid2中。 1. Grid1定义： var sm1 = n 阅读详情

extjs 2.0 使用gridPanel加载数据特别慢，后台数据库（sql2008）一共才不到150条，绑定控件后加载时需要将尽2分钟，这是什么原因？网上找了好多的资料，都不行啊，数据绑定主要是通过store里的OnReadData="MyData_Refresh5"，然后调用后台方法实现的

 <ext:GridPanel ID="GridPanel4" runat="server" Title="<font style='font-size:13; font-weight:900; font-family: Arial,Tahoma, '微软雅黑';'>新蒜货源</font>"
