推荐答案

使用Gridview显示问题，然后使用分页，为网格视图设置AllowPaging =True并设置PageSize =15，然后在网格视图的pageindexchanging事件上写下面的代码

Use Gridview to display questions and then use pagination , for that set AllowPaging="True" for grid view and set PageSize="15", and then write following code on pageindexchanging event of grid view

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    loadgrid(); // function to load gridview

}

你应该使用ajax部分渲染功能您应该使用更新面板来消除问题网格。

并使用asynchpostbacktrigger在gridview上加载下一个问题集。

You should use ajax partial rendering feature and for that you should use update panel to disaply questions grid.
And use asynchpostbacktrigger to load next question sets on gridview.
