[Solved] RadGrid auto reload many time with chrome, but firefox and safari doesn't

[Tien]

My website uses Telerik RadGrid version ASP.NET AJAX. In mid-July, after Google updated Chrome, for a while, the page using RadGrid kept reloading continuously and added ? at the end of the address. ctl00_ContentPlaceHolder1_gvArticleChangePage=1, had to restart IIS to resolve the issue, but it reoccurred after a few days. At the same time, opening it with Safari and Firefox had no issues at all. I suspect that Chrome has updated some feature, so may I ask how to fix.  

All pages using radgrid are affected, for example, one radgrid is currently affected.

 

<telerik:RadGrid ID="gvResults" runat="server" AutoGenerateColumns="False" AllowPaging="True" AllowSorting="True" Skin="Windows7" GridLines="None" AllowMultiRowSelection="True">
            <PagerStyle Mode="NextPrevAndNumeric" PagerTextFormat="Change page: {4} {5} văn bản / {1} trang" PageSizeLabelText="S12" />
            <MasterTableView ClientDataKeyNames="Id" AllowMultiColumnSorting="True" NoMasterRecordsText="Không tìm thấy dữ liệu.">
                <Columns>
                    <telerik:GridBoundColumn HeaderText="Số ký hiệu" DataField="Notation" HeaderStyle-Width="120px">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn HeaderText="Ngày ký" DataField="CreatedDate" HeaderStyle-Width="70px" DataFormatString="{0:dd/MM/yyyy}">
                    </telerik:GridBoundColumn>                
                </Columns>
            </MasterTableView>
            <ClientSettings EnableRowHoverStyle="true">
                <Selecting AllowRowSelect="True" />
                <ClientEvents OnCommand="gvResults_Command" />
            </ClientSettings>
        </telerik:RadGrid>

Hi Tien,

Thank you for reporting this problem!

This is a known issue that has already been logged in our feedback portal as RadGrid SEO Paging turns on due to crawler detection and addressed internally. The fix will appear in the next official release, which date is not yet decided but will be in September.

As a temporary workaround you could try the following workaround to solve the issue

let $T = Telerik.Web.UI;

if ($T && $T.Grid) {
    $T.Grid.ChangePageSizeComboHandler = function (sender, args) {
        var item;
        if (args.get_item) {
            item = args.get_item();
        } else if (args.get_index) {
            item = sender.get_items().getItem(args.get_index());
        }

        if (item) {
            var ownerTableViewId = item.get_attributes().getAttribute('ownerTableViewId');
            var newPageSize = null;

            if (sender.get_value) {
                if (sender.get_value()) {
                    newPageSize = sender.get_value();
                } else {
                    newPageSize = sender.get_text();
                }
            } else {
                if (item.get_value()) {
                    newPageSize = item.get_value();
                } else {
                    newPageSize = item.get_text();
                }
            }


            if (ownerTableViewId && newPageSize) {
                var value = parseInt(newPageSize, 10);
                var tableView = $find(ownerTableViewId);

                if (tableView) {
                    var seoUrl = item.get_attributes().getAttribute('seoRedirectUrl');

                    if (seoUrl) {
                        // Comment out or remove this line to prevent the page from redirecting to the SEO URL
                        // window.location.href = seoUrl;

                        return false;
                    }

                    tableView.set_pageSize(value);
                }
            }
        }
    };
}

Once again, thank you again for bringing this to our attention.

Hi Tien,

We've postponed the service pack release to incorporate a larger set of fixes, including the RadGrid Chrome paging issue you reported. The updated release is now planned for the second half of October.

Until then, the workaround I shared earlier remains valid and should keep the problem under control. After you upgrade to the new version, you can safely remove the workaround code from your project, as the fix will be included in the official build.

Regarding the update process: once the service pack is available, you can follow the step-by-step instructions provided in the manual upgrade article.
