Hi All,

I need help. I am using RadGrid for Read News page. I want to display one news per page. Also, I have an other page which is news list display. what I am doing is: when user click news title(from news list page) open my read news page(it has RadGrid) and display that news, also on the bottom have page navigator, which is user click next news it will open next news.
My problem is I cannot open user clicked news. It always open my last news. So, I need some one help me to fix this problem.

Hi,


Try the code snippet below to set the selected news item as the default value  on redirect .

        protected void RadGrid1_PreRender(object sender, EventArgs e)
        {
            int currentPageIndex = RadGrid1.CurrentPageIndex;
            for (int i = 0; i < RadGrid1.PageCount; i++)
            {
                // Compare NewsID of each item in the current RadGrid page with the selected News ID
                foreach (GridDataItem item in RadGrid1.Items)
                {
                    if (Request.QueryString["NewsID"].ToString().Equals((item["NewsID"].Text)))
                    {
                        // Select the item
                        item.Selected = true;
                        currentPageIndex = -1; // flag exit
                        break;
                    }
                }

                // If item is found then exit RadGrid page loop
                if (currentPageIndex.Equals(-1))
                    break;

                // Go to next RadGrid page
                currentPageIndex++;
                if (currentPageIndex >= RadGrid1.PageCount)
                    currentPageIndex = 0;
                RadGrid1.CurrentPageIndex = currentPageIndex;
                RadGrid1.Rebind();
            }

        }

Thanks,

Thank you very much for your reply,

But, it would not work properly. because, I open new page with brand new RadGrid. the RadGrid bind with code behind. So, Current items id is null. it cannot compare to request.querystring.
