Telerik radgrid不记得页码 [英] Telerik radgrid doesn't remember page number

问题描述

我的页面上有一个telerik radgrid控件，用于显示文章列表.如果单击页面，然后单击文章，然后再次返回列表，那么我将返回首页，而不是之前的页面.

I have a telerik radgrid-control on my page for showing a list of articles. If I click a page, then an article and then back to the list again I am back at the first page instead of the one I was at before.

有解决方案吗?

推荐答案

我假设您正在执行回发，并且事情在服务器端...

I'm assuming you're doing a postback and things are server side...

这是一个两步过程...

This is a 2 step process...

首先，在单击文章的OnClick事件中，将页面索引放入会话变量中.

First in the OnClick event for clicking on an article, put the page index into a session variable.

第二，在RadGrid的PreRender事件中，从先前设置的会话变量中获取页面索引.

Second, in the RadGrid's PreRender event get the page index from that previously set session variable.

// Set the page index, call this on your OnClick event
private void SetRadGridPageIndex(int PageIndex)
{
    Session["RadGridCurrentPageIndex"] = PageIndex;
}

// Get the page index, call this on RadGrid's PreRender event
// Don't forget to Rebind the RadGrid
private void GetRadGridPageIndex()
{
    // Go to the previously selected page
    if (Session["RadGridCurrentPageIndex"] != null)
    {
        this.RadGrid1.CurrentPageIndex = Convert.ToInt32(Session["RadGridCurrentPageIndex"]);
        this.RadGrid1.MasterTableView.Rebind();
    }
}
