When scroll inside RadGrid in Chrome on a mobile device or in the DevTools responsive/mobile mode, the browser throws [Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See  https://www.chromestatus.com/features/5093566007214080. I get 1 error message for every pixel the grid scrolls. 

The problem is due to jQuery and is reproducible with 1.12.4 and 3.3.1 versions of it.

RadGrid base styles override skins e.g. "border: 1px solid" will override any value for "border-color" that come from non-embed skins.

with client-side databinding when setting sort/filter expressions on button click and then calling the rebind or set_currentPageIndex methods the control makes multiple requests to the web service.

The RadGrid OnDataBindingFailed event does not fire when WCF/WebService returns an IIS 500 Errror page.

It DOES, however, fire when IIS returns a proper 500 error JSON response.

In my case, the former was happening because my ASP.NET WCF services were incorrectly configured and thus throwing a standard IIS 500 error page. RadGrid should recognize the IIS 500 page as failure and spawned a OnDataBindingFailed  event.

NOTE: For example, RadScheduler *does* correctly interpret the IIS 500 page as a failure (RE: OnClientRequestFailed).

Since Q3 a change in the client-side binding of the GridTemplateColumn has been introduced. The column no longer automatically populates controls in the ItemTemplate. The change is result of an optimization in code regarding the virtualization and batch editing features of the grid. The new behavior is far more optimized and ensures much faster and robust operation of the control in various cases of client-side binding.

With the use of the "UseStaticHeaders"-Parameter all ARIA-Tags are gone in the rendered RadGrid.
We need the support of WAI-ARIA in our application for our customer.
Dont using this Parameter is no option for us.
You are not telling this missing function in your documentation.

To reproduce the issue enable RowSelect and RowsDragDrop ClientSettings, and attach OnRowDropping  event listener

<ClientSettings AllowRowsDragDrop="true">
    <Selecting AllowRowSelect="true" />
    <ClientEvents OnRowDropping="function() {alert('RowDrooping event fired!');}"/>
</ClientSettings>

If using Frozen Columns with MultiHeaders, where one column has many headers while the other fewer. Each header in a column occupies some space and they get hidden, this will cause the upper (header) portion of the Grid to change its size. With that, the scrollbar will move away from the mouse position and causes the scrolling jump back and forth resulting in flickering.

Demo video of the issue: RadGrid FrozenColumns Flickering Header. The video can be found in the attachments as well.

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 System.Data.DataTable.ParseSortString(String sortString)

                  at Telerik.Web.UI.GridEnumerableFromDataView.TransformEnumerable()
                  at Telerik.Web.UI.GridTableView.GetEnumerator(Boolean useDataSource, GridEnumerableBase resolvedDataSource, ArrayList dataKeysArray, Boolean shouldClearDataKeys)
                  at Telerik.Web.UI.GridTableView.CreateControlHierarchy(Boolean useDataSource)
                  at Telerik.Web.UI.GridTableView.CreateChildControls(IEnumerable dataSource, Boolean useDataSource)
                  at System.Web.UI.WebControls.CompositeDataBoundControl.PerformDataBinding(IEnumerable data)
                  at System.Web.UI.WebControls.DataBoundControl.OnDataSourceViewSelectCallback(IEnumerable data)
                  at Telerik.Web.UI.GridTableView.PerformSelect()
                  at Telerik.Web.UI.GridTableView.DataBind()
                  at Telerik.Web.UI.GridItemBuilder.BindDetailTable(GridDataItem parentItem, GridTableView cloned)
                  at Telerik.Web.UI.GridItemBuilder.BindDetailTables(GridDataItem parentItem, GridNestedViewItem detailItem)
                  at Telerik.Web.UI.GridItemBuilder.CreateItems(GridGroupingContext group)
                  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 System.Web.UI.WebControls.CompositeDataBoundControl.PerformDataBinding(IEnumerable data)
                  at System.Web.UI.WebControls.DataBoundControl.OnDataSourceViewSelectCallback(IEnumerable data)
                  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

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.
