Question

gridview激发了未处理事件“PageIndexChanging”

因为gridview的数据源是改变的 所以PageIndexChanging不知道该怎么写……
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
}这样的时候 随便点个页码 就不显示了 因为没有绑定数据
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex; GridView1.datasource="数据源";
GridView1.DataBind();
}这样的话又不知道怎么控制了……因为有3个数据源控制GridView加载的时候显示全部 当下拉列表改变的时候GridView也要改变……求高手帮忙 谢啦

就再你的翻页事件里做个判断就可以了protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex; if(Droplownlist.selectitem.text=="aa") { GridView1.datasource="数据源1";
GridView1.DataBind(); } else if(Droplownlist.selectitem.text=="bb") { GridView1.datasource="数据源2";
GridView1.DataBind(); }else{ GridView1.datasource="数据源3";
GridView1.DataBind(); }
}
