In version 2026.1.218.462 the Grid cannot scroll vertically. To work around  it, you can overwrite the built-in function used for scrolling:

<script type="text/javascript">
    Sys.Application.add_init(function () {
        Telerik.Web.UI.GridScrolling.prototype._createTouchScrollExtender = function (toCreate) {
            var contentElement = this._owner.GridDataDiv;

            if (contentElement) {
                var control = this._dropDownTouchScroll;

                if (control) {
                    if (!toCreate) {
                        control.dispose();
                        this._dropDownTouchScroll = null;
                    }
                } else if (toCreate) {
                    this._dropDownTouchScroll = new Telerik.Web.UI.TouchScrollExtender(contentElement);
                    this._dropDownTouchScroll.initialize();

                    if (this.AllowScroll) {
                        contentElement.style.overflow = 'auto';
                    }
                }
            }
        };
    });
</script>

Good morning,

we have a strange issue using RadGrid with horizontal scroll and frozen columns: there a resizing of the height which gets user experience not the best.

See attached gif.

Could you please help us?

RadGrid’s SEO Paging activates for normal users in the latest Brave browser, because sessions are misclassified as crawlers (Request.Browser.Crawler evaluates to true).

Even with PagerStyle.EnableSEOPaging set to False, SEO paging still turns on due to crawler detection, and ask whether the legacy Request.Browser.Crawler approach should be removed for ASP.NET WebForms in Telerik.

When EnableSEOPaging is True, query string paging is always used, but when False, the grid still enables SEO paging upon crawler detection, which is being incorrectly triggered in Brave.

It seems the element somehow considmes the scrolling/touch action and the grid does not scroll unless you hit the gap where the custom element does not reach.

A workaround is to enforce overflow: auto to the scrollable element of the grid. A sample is attached below.

        div.rgDataDiv {
            overflow: auto !important;
        }

RadGrid HeaderContext filter menu throws '_linkElement' undefined error after expand animation ends in version 2026.1.211.462

After clicking the filter icon in a RadGrid column header, the filter menu throws the following JavaScript error in the browser console:

Uncaught TypeError: Cannot read properties of undefined (reading '_linkElement')
    at Object._focusFirstItem
    at Object.raise_expandAnimationEnded
    at Object._onExpandAnimationEnded

Environment:
- Telerik UI for ASP.NET AJAX version: 2026.1.211.462
- ASP.NET Framework: 4.8.1
- Browser: Chrome (latest)
- FilterType: default
- RadScriptManager with no custom script references

Steps to reproduce:
1. Place a RadGrid with AllowFilteringByColumn="true"
2. Run the application
3. Click the filter icon on any column header
4. Observe the JavaScript error in the browser console after the menu animation completes

Expected behavior:
The filter menu opens and focus is set on the first menu item without any errors.

Actual behavior:

The filter menu disappears visually, does not appear, and throws a JS exception when attempting to focus the first item (_linkElement is undefined)

Form controls rendered by the embedded columns (GridBoundColumn, GridDateTimeColumn, GridNumericColumn, etc.) in EditMode="Batch" do not have a label set and fail the accessibility checks.

When the Grid is groupped and showing/hiding columns on client-side, the table layout is broken. More specifically, the cell's colspan does not get adjusted when another cell gets hidden.

To replicate the problem:

1. Create a grid and bind it to data
2. Set the EnableHeaderContextMenu to true
3. Load the page
4. Right-click on a column's header to bring up the contextmenu and click "Group By"
5. Right click on a column's header to bring up the contextmenu again and show/hide a few columns from the "Columns" menu.

We discovered the following is not working in RadGrid's ItemDataBound nor in ItemCreated events:

            Dim imgbtn As ElasticButton
            Dim imgbtn1 As ElasticButton
            imgbtn = DirectCast(Item("btn_sequp").Controls(0), ElasticButton)
            imgbtn1 = DirectCast(Item("btn_seqdown").Controls(0), ElasticButton)
            imgbtn.SecondSpanClass = "d-none"
            imgbtn1.SecondSpanClass = "d-none"

So we had to set through CSS like:

While the Keyboard navigation is enabled, navigating through the items using the UP/DOWN arrows does mark the rows active, however, the active styles remain for the rows even if they aren't active anymore.

The issue happens when using the ActiveItemStyle element to define the styles (e.g. ForeColor, BackColor, etc.). Works as expected using the default styles.

Code to replicate the issue

<script runat="server">
    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        (sender as RadGrid).DataSource = Enumerable.Range(1, 5).Select(x => new
        {
            OrderID = x,
            OrderDate = DateTime.Now.Date.AddDays(x),
            Freight = x * 0.1m,
            ShipName = "Name " + x,
            ShipCountry = "Country " + x
        }).ToList();
    }
</script>

<telerik:RadGrid ID="RadGrid1" runat="server" RenderMode="Lightweight" OnNeedDataSource="RadGrid1_NeedDataSource">
    <ActiveItemStyle BackColor="Red" ForeColor="White" />
    <ClientSettings AllowKeyboardNavigation="true">
    </ClientSettings>
</telerik:RadGrid>

Noticed that when using a template to custom define the pager look, the pager gets rendered in a TD and not a TH as expected since the pager is in a THEAD.  Could the header pager only be modified to render in TH?  This would allow all elements in the header to render the same and help with styling.

In version 2025 Q2, I am getting the following error message when opening the RadGrid in design mode: 

System.NullReferenceException: Object reference not set to an instance of an object. at Telerik.Web.UI.Licensing.TelerikLicense.get_CurrentHost() at Telerik.Web.UI.Licensing.TelerikLicense.get_IsLicenseValid() at Telerik.Web.UI.RadGrid.Render(HtmlTextWriter writer) at System.Web.UI.Control.RenderControlInternal(HtmlTextWriter writer, ControlAdapter adapter) at System.Web.UI.Design.ControlDesigner.GetDesignTimeHtml()

Business Need - User Story Terminology:

As a Telerik Support Specialist, I would like our programmers to incorporate new code which will treat hyphens as if it were a space upon ExportToPdf() so that we gracefully handle for scenarios where a very long word with a hyphen will wrap to the next line instead of overlapping other content.

RadGrid.MasterTableView.ExportToPdf() - we would like telerik to update logic to do a normal word wrap when a hyphen exists rather than not wrapping when there's not enough room in the grid cell | View Ticket | Your Account

Hi,

In the Glow Theme the Filter Input Box is not visible.
