The following steps create this issue:
1. Use html 4
2. Use telerik AJAX (For consistency)
3. Set a radgrid with some columns that reach beyond the extent of its element (such that it requires horizontal scrolling). Use at least four columns. One being the GridClientSelectColumn.
4. Have the following settings:
Control Settings: 
AllowPaging=true,AllowSorting=true,AllowFiltering=true,AllowFilteringByColumn=true,AllowMultiRowSelection=true

Control Events Used: NeedDataSource,OnItemDataBound
Client Settings:
EnablePostBackOnRowClick=false,Resizing AllowColumnResize=true, Selecting AllowRowSelect=true,UseClientSelectColumnOnly=false,Scrolling,AutoGenerateColumns=false,AllowScroll=true,UseStaticHeaders=true

Important note: Retain data on the server, rebind, and, on item databound, select the previously selected rows.

Set up a button to perform some action on the selected rows and have this action use AJAX such that this action depends on the currently selected rows in the RadGrid.

5. Scroll away from the selection checkboxes
6. Select some rows in your RadGrid
7. Perform your action with AJAX
If all was set up correctly, your grid should have been rebound with the previously selected rows re-selected. The RadGrid should still be scrolled to its previous position.
8. Perform your action with AJAX again. Here's the bug, the grid states that it has no selected items; however, the client shows that there are items selected in the UI.

This may be related to "RadGrid's last selected item index is not persisted correctly when two or more postbacks are triggered from external controls."

In GridTableView.cs, you provide a function
 protected virtual GridTableView CreateTableView() (Line 7828).
This function can be overloaded to return derived classes from GridTableView.

But, this is not overloadable completely. Because you create a GridTableView directly in protected void BuildDetailTablesFromDataSource() (Line 8808), too.
There you would have to call a virtual creator function, too.

This is necessary, because I have a lot of Trouble with your DataBind which I was able to fix with an overload. It is much to hard to make this bug visible for you, I really tried to do so already, but I had to fix this that way, because your GridTableView without my derivation fails in our szenario.

The call stack for that problem, I'd had to fix, is always like:
Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IndexOutOfRangeException: Cannot find column CheckSum.

                  at Telerik.Web.UI.GridTableView.CreateItems(IEnumerator enumerator, GridColumn[] columns, ControlCollection controls)
                  at Telerik.Web.UI.GridTableView.CreateControlHierarchy(Boolean useDataSource)
                  at Telerik.Web.UI.GridTableView.CreateChildControls(IEnumerable dataSource, Boolean useDataSource)

                  at Telerik.Web.UI.GridTableView.PerformSelect()
                  at Telerik.Web.UI.GridTableView.DataBind()


In that, your DataTableView gets an invalid sort Expression string. Therefore, I overwrote DataBind.

But this is not possible in all cases, if you create GridViewTable() objects on your own.

Best regards

I skipped the 3rd quarter 2016 update (2016.3.1027) for my copy of Telerik UI for ASP.NET.AJAX, since we were in code lock down at that time. 

 Later i installed the 4th quarter version (2016.4.1021.0)

Now, I still get a notice to install the previous version  (2016.3.1027) that I skipped.

That's annoying, and probably not possible. Right?

Is there anything we can do about this situation?

Thanks in advance

If the Chrome browser zoom is different from 100%, it is not possible to reorder the RadGrid columns.

The problem can be reproduced at https://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/columns/column-row-resize-reorder/defaultcs.aspx .

Reference: http://www.telerik.com/forums/radgrid-column-header-and-data-item-alignment-problem

This has apparently been an issue with RadGrid for a long time, according to the above thread. I have done a significant amount of testing to isolate this bug and have attached a self-contained solution in VB.NET 4.0 (VS 2010).

I removed all the surplus RadGrid properties I could in order to simplify the debugging process on your end and included my notes in the code and on the test page. There is indeed some peculiar behavior with the control.

Regards,
Matthew

The problem for which the bug was opened was not actually caused by the RadGrid. It was triggered by wrong configuration of the test sample. The parent container which held the grid had disabled ViewState in which case it is expected for the filter values and filter functions to not persist.

When Grouping on an Integer value, the groups are not ordering correctly. i.e. if you group on values {864, 1455, 1494}, the actual order comes out as {1455, 1494, 864}.

Ordering on the same data, but converted to a string and padded to the left with zeros resolves this issue.

It is possible to have "{4} | Page {0} of {1}, items {2} to {3} of {5}" (all 6 parameters) for PagerTextFormat, but not just "items {2} to {3} of {5}".

In HeaderContextMenu was made a typo in item value. TopGroupSeparator is typed as TopGroupSeperator. I've wasted 10 minutes to find out why JS code is not working.
