三个不同数据库的分页代码怎么写

页面上有三个GridView，这三个GridView分别来源于不同的数据库
下面的代码是只实现了最后一个的数据库，尚未实现前两个
怎么样写才能让所有的GridView能正确读取数据库并且分页，求大神进
protected void NozzleDgvRequests_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
NozzleDgvRequests.PageIndex = e.NewPageIndex;
this.NozzleDgvRequests.DataSource = ViewState["table"];
this.NozzleDgvRequests.DataBind();
}

    protected void FeederDgvRequests_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        FeederDgvRequests.PageIndex = e.NewPageIndex;
        this.FeederDgvRequests.DataSource = ViewState["table"];
        this.FeederDgvRequests.DataBind();
    }

    protected void HeaderDgvRequests_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        HeaderDgvRequests.PageIndex = e.NewPageIndex;
        this.HeaderDgvRequests.DataSource = ViewState["table"];
        this.HeaderDgvRequests.DataBind();
    }

问题已解决，其实要用到上面对应的连接数据库的代码复制到各个代码块
