先生.

我在asp.net中有一个gridview控件.它有一个编辑链接按钮.当我单击另一页时打开.我在网格视图中使用内置分页.假设我有5页.我的问题是当我从2,3,4页返回，然后从另一页返回到默认具有网格视图的页面，该页面显示第一页的内容而不显示最近选择的页面的内容.

推荐答案

执行以下操作.

1.在Page_Load事件中绑定GridView.
2.实现GridView的PageIndexChanging事件.

Do the following.

1. Bind the GridView in Page_Load event.
2. Implement PageIndexChanging event of the GridView.

protected void Page_Load(object sender, System.EventArgs e)
{
    if (!IsPostBack) {
        bindControls();
    }
}

protected void GridView1_PageIndexChanging(object sender, System.Web.UI.WebControls.GridViewPageEventArgs e)
{
    GridView1.PageIndex = e.NewPageIndex;
    bindControls();
}

private void bindControls()
{
    BusinessLogicFacade businessLogic = new BusinessLogicFacade();// Change to your data source class and bind the GridView.
    GridView1.DataSource = businessLogic.GetData();
    GridView1.DataBind();
}

Protected Sub grdGoods_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles grdGoods.PageIndexChanging
    grdGoods.PageIndex = e.NewPageIndex
    grdGoods.DataSource =  DataTable 'that is populated by a query
    grdGoods.DataBind()
End Sub
