推荐答案

您可以执行以下任务来实现此目的.

1)创建一个类级别的静态DataTable

You can to do following task to achieve this.

1) create a class level static DataTable

static DataTable dtDataForGrid= new DataTable();

2)在Page_Load方法中，填充DataTable dtDataForGrid并将其与GridView绑定.

2)In the Page_Load method , fill DataTable dtDataForGrid and bind it with GridView.

dtDataForGrid.Rows.Clear();

  //code to fill the DataTable dtDataForGrid

GridView1.DataSource = dtDataForGrid;
GridView1.DataBind();

3)完成上述工作后.生成GridView1_PageIndexChanging事件.并编写以下代码.

3) After doing above job. generate the GridView1_PageIndexChanging event. and write the following code.

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
   {
       GridView1.PageIndex = e.NewPageIndex;
       GridView1.DataSource = dtDataForGrid;
       GridView1.DataBind();

   }

希望这对您有所帮助.

所以，

创建网格视图的pageindexchange事件，并将新的页面索引分配给网格视图.

So,

create event of pageindexchange of grid view and assign the new page index to grid view.

protected void GridSummary_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        try
        {
            if (e.NewPageIndex != -1)
            {
                GridSummary.PageIndex = e.NewPageIndex;
                // Call the method to assing datasource to grid view again
            }
            else
            {
                
            }
        }
        catch
        {
        }

    }
