    I have a RadGrid with paging.  There are 45 pages with 10 items per page.  If I call RadGrid1.Items, I only get the 10 items on the first page.  I want to get all 450 items.  How would I go about doing this?  Thanks.

    Hello Karty,

    In order to access all GridDataItems ,disable the paging property. After accessing the data ,set the paging with desired size.Try the following code.

    C#:
    protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
           RadGrid1.AllowPaging = false;
            foreach (GridDataItem item in RadGrid1.Items)
            {
                //access the item
            }
            RadGrid1.AllowPaging = true;
            RadGrid1.PageSize = 3;
            RadGrid1.Rebind();
    }

    Thanks,
    Princy.

    Hi Rohan,

    Try the following code snippet to achieve your scenario.

    C#:
    protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        RadGrid1.AllowPaging = false;
        RadGrid1.Rebind();
        foreach (GridDataItem item in RadGrid1.Items)
        {
            //Your code
        }
        RadGrid1.AllowPaging = true;
        RadGrid1.PageSize = 3;
        RadGrid1.Rebind();
    }

    Hope this helps.

    Regards,
    Princy.

    Hello Rohan,

    You could save the selected items in a collection variable and use it when necessary:
    http://www.telerik.com/help/aspnet-ajax/grid-persist-selected-rows-client-sorting-paging-grouping-filtering.html
    or
    http://www.telerik.com/help/aspnet-ajax/grid-persist-selected-rows-on-sorting.html

    I hope this will prove helpful.

    All the best,

    Hi Rohan,

    I have created a sample RadGrid web site where I implemented preserving and accessing the selected items on filter command. Please check out the attached application and let me know about the result.

    Kind regards,
