Hello everyone,
our team found the issue in frozen columns functionality. If grid has no data, user can not scrolling header to the right.
Maybe we incorrect using this functionality. I created small demo that is based on a server-side binding, but problem is still, after scrolling in developer tools we can see JS error "Uncaught TypeError: Cannot read property 'cells' of undefined
at Object.Telerik.Web.UI.Grid.frozenScrollHanlder (Telerik.Web.UI.WebResource.axd... :3454)
at <anonymous>:1:21"

Sorry, I accidentally pressed "Post"
We are using RadGrid from Telerik ASP.NET Ajax library.
This is my demo .aspx code:
<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title>Telerik ASP.NET Example</title></head><body> <form id="form1" runat="server"> <telerik:RadScriptManager runat="server" ID="RadScriptManager1"/> <telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server"> <ClientSettings> <Scrolling AllowScroll="True" UseStaticHeaders="True" FrozenColumnsCount="2"></Scrolling> </ClientSettings> <MasterTableView ></MasterTableView> <HeaderStyle Width="200px" /> </telerik:RadGrid> </form></body></html>
This is my demo .vb code:
Imports Telerik.Web.UIPublic Class Demo Inherits System.Web.UI.Page Public Class PersonData Private _ID As Int16 Private _Name As String Private _Age As Int16 Public Property ID() As Int16 Get Return _ID End Get Set(ByVal Value As Int16) _ID = Value End Set End Property Public Property Name() As String Get Return _Name End Get Set(ByVal Value As String) _Name = Value End Set End Property Public Property Age() As Int16 Get Return _Age End Get Set(ByVal Value As Int16) _Age = Value End Set End Property End Class Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load End Sub Private Sub RadGrid1_NeedDataSource(sender As Object, e As GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource RadGrid1.DataSource = New List(Of PersonData) End SubEnd Class
I was not able to reproduce this with our latest version (R3 2018 at the moment) so I would advise that you upgrade to it to get it fixed. If you can reproduce such an error with the latest version, please open a support ticket and send us a runnable example we can investigate, because the provided snippets work fine on my end and I do not get errors.
