Hi,

Our Accessibility partner while evaluating our product for 508 compliance we got one report saying RadGrid control is not accessible. We do have enablearia attribute on the radgrid and is emitting the aria-attributes as mentioned in your demo. 
http://demos.telerik.com/aspnet-ajax/grid/examples/accessibility-and-internationalization/wai-aria-support/defaultcs.aspx

As per them : "So it does not alert the user that arrow keys may be used to navigate it".
I have attached a snippet of their report regarding radgrid accessibility. Can you please let me know if anything is missing.
Thanks and best regards,
Mirang

Currently when doing a Batch Edit with the Grid each row and cell must be updated with a new/edited value before saving.

Example: a User has a Grid containing records and would like to update several records because a Date field requires updating.

Can it be possible for the User to select the Rows they would like to update, Edit the Date Field(using the example above), but this time when Saved all records that were selected are updated. 

This solution may require a modal to be displayed that shows all fields available, similar to Edit/Insert grid Popup. The appropriate field is then updated and saved only to selected records.

This feature would save a lot of time by not having to edit each row individually then saving.

If AllowPaging, AllowScroll and UseStaticHeaders are set to true, then there will be 2 empty <th> elements

workaround: 
    <ClientSettings>
...
        <ClientEvents OnGridCreated="OnGridCreated" />
    </ClientSettings>

<script>
    function OnGridCreated(sender, args) {
        var emptyth = $telerik.$(sender.get_element())
            .find("th").filter(function (ind, item) { return item.textContent == "" });
        // alert(emptyth.length)
        emptyth.append("<span style='display:none'>Hidden empty table header</span>")
    }
</script>

Images that reside in the grid will get resized (scaled down with about 3-5 %) which might cause issues, specially if exporting bar-codes, thus the bar-code scanners won't be able to read them.

Current workaround is to use the Telerik Documents Processing Library  and build the table manually where the images are inserted without changing the size.

Here is an example:

        protected void RadGrid1_InfrastructureExporting(object sender, GridInfrastructureExportingEventArgs e)
        {
            Telerik.Web.UI.ExportInfrastructure.Table table = e.ExportStructure.Tables[0];

            Workbook workbook = new Workbook();
            workbook.Worksheets.Add();

            Worksheet worksheet = workbook.ActiveWorksheet;


            foreach (var row in table.Rows)
            {
                if (row.Index > 1)
                {
                    worksheet.Rows[row.Index - 1].SetHeight(new RowHeight(55, true));
                }

                foreach (var cell in row.Cells)
                {
                    if (row.Index == 1 || cell.ColIndex != 2)
                    {
                        worksheet.Cells[cell.Index.Y - 1, cell.Index.X - 1].SetValue(cell.Value.ToString());
                    }
                    else
                    {
                        FloatingImage image = new FloatingImage(worksheet, new CellIndex(cell.Index.Y - 1, cell.Index.X - 1), 0, 0);
                        Stream stream = File.Open(Server.MapPath(cell.Value.ToString()), FileMode.Open);
                        using (stream)
                        {
                            image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(stream, "jpg");
                        }
                        worksheet.Shapes.Add(image);
                    }
                }
            }

            byte[] data;

            using (MemoryStream ms = new MemoryStream())
            {
                XlsxFormatProvider xlsProvider = new XlsxFormatProvider();
                xlsProvider.Export(workbook, ms);
                data = ms.ToArray();
            }

            Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
            Response.Headers.Remove("Content-Disposition");
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + RadGridLista.ExportSettings.FileName + ".xlsx");
            Response.BinaryWrite(data);
            Response.End();
        }

A valid SQL statement should look like

SELECT * FROM Products WHERE ([Discontinued] = 1)

or

SELECT * FROM Products WHERE ([Discontinued] = 'True')

but RadGrid provides something like

([Discontinued] = True)

in the MasterTableView.FilterExpression property.

By default RadGrid filters the data on its own after retrieving the entire data set form the data source, and the filtering operation works like that.
If you will be using the filter expression provided by the grid in a custom data source operation you may need to tweak the string first.
Note that changing this may result in a breaking change if you are already using the current syntax.

GridAttachmentColumn malforms the String filepath, from "C\SomePath\SomeFile.PDF" to something like "C:" & vbBack &"SomePathSomeFile.PDF"

Steps to reproduce the error:

DataSource Bound to grid:

Private Function SomeTable() As DataTable
    Dim dt As New DataTable()
 
    dt.Columns.Add(New DataColumn("FieldName", Type.GetType("System.String")))
 
    row("FieldName") = "C:\SomeDirectory\RadGridExport.pdf"
    dt.Rows.Add(row)
 
    Return dt
End Function

GridAttachmentColumn markup as well as the ObjectDataSource that returns a byte array when user clicks on download attachment:

<telerik:GridAttachmentColumn DataSourceID="ObjectDataSource1"
    HeaderText="Attachment Column"
    AttachmentKeyFields="FieldName"
    AttachmentDataField="FieldName"
    DataTextField="FieldName"
    UniqueName="FieldName"
    ButtonType="ImageButton"
    UploadControlType="RadAsyncUpload"
    FileName="RadGridExport.pdf"
    ImageUrl="pdf-icon.png"
    ItemStyle-Height="36px"
    ItemStyle-Width="36px" >
</telerik:GridAttachmentColumn>
                         
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="MySelectMethod" TypeName="MyApp">
    <SelectParameters>
        <asp:Parameter Name="FieldName" Type="String" />
    </SelectParameters>
</asp:ObjectDataSource>

MyApp.MySelectMethod that is supposed access the file by "filePath" and read it to byte, but the filePath is malformed, hence throws an exception.

Public Class MyApp
    <DataObjectMethodAttribute(DataObjectMethodType.Select, True)>
    Public Function MySelectMethod(filePath As String) As DataTable
        Dim dt As New DataTable("Base")
        Dim col As New DataColumn("FieldName")
        col.DataType = System.Type.GetType("System.Byte[]")
        dt.Columns.Add(col)
        Dim row As DataRow = dt.NewRow
        row(0) = My.Computer.FileSystem.ReadAllBytes(filePath)
 
        dt.Rows.Add(row)
        Return dt
    End Function
End Class

Description:

If RadGrid has UseStaticHeaders enabled, different HTML Tables are rendered and instructing JAWS to read the tables one by one will also read the Header. It would say Header with "n" number of columns and one rows, since the table has only one row and that is containing the Column Names.

Goal:

It would be great, if the grid with Static Header could be made in a way that JAWS will only treat the grid as one Table instead of two separate tables.

Workaround and discussion:

When resizing a column in RTL, expectation is to use the left side of a column to expand/shrink it. Instead I have to use the right side. Grabbing the left side resizes the next column on the left and is very confusing for people who are used to think in RTL

Release R2 2020

Replicated when the ClickToOpen is enabled: 

protected void Page_Load(object sender, EventArgs e) { RadGrid1.HeaderContextMenu.ClickToOpen = true; }

WORKAROUND: Loading the following script under the script manager

<script>
    var original = Telerik.Web.UI.GridColumn.prototype._onContextMenuItemClicking;
    Telerik.Web.UI.GridColumn.prototype._onContextMenuItemClicking = function (sender, args) {
        original.call(this, sender, args);
                
        var item = args.get_item();
        var itemValue = item.get_value();
        if (itemValue == "FilterList" || itemValue == "FilterMenuContainer" ||
            itemValue == "AggregatesContainer" || itemValue == "FilterMenuParent" || itemValue == "ColumnsContainer" ||
            (Telerik.Web.UI.RadMenuItem.isInstanceOfType(item.get_parent()) && item.get_parent().get_value() == "ColumnsContainer")) {
            if (sender.get_clickToOpen()) {
                args.get_item().open();
            }
        }

When using iPad touch to open the header context menu of a grid column, an immediate postback prevents the opening of the menu when the RadGrid is in Mobile RenderMode. The reason is that this action gets recognized as dragging when AllowDragToGroup is enabled.

Unable to open "columns" sub-menu inside RadGrid's HeaderContextMenu on mobile devices. It does work on desktop PCs regardless of the OS.

Issue can be replicated starting with the version 2019 R1. Not present on previous versions (2017 and 2018 were tested)

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.

In a GridDateTimeColumn I have some value data with milliseconds like "2018-09-24 18:05:21.057"

Filtering with the milliseconds returns no results.

Then I remove milliseconds part "2018-09-24 18:05:21"

Filtering without that will return results.

Even with the EnableTimeIndependentFiltering property set to True, the milliseconds are not ignored, and the filtering mechanism doesn't find the records.

Issue #1. When the Grid is not having any records (i.e. when the grid is initialized for the first time), if we define the Detail Item Template than the item template is shown 10-11 times. 

Issue#2: When we have the pagination enabled in the grid and the records are fully filled on the first page and suppose the second page is half-filled with records, then in this scenario On the second page even the records of the first page are hidden but the data item template for those rows are visible which is not correct. Screenshot is attached.

Issue #3: The same scenario is happening when we searched the grid first with 10 records and then we search for 2 records, In this case also 8 records will be removed but there data item templates will still be visible on the grid.

Hello @support!

Did you observe the behavior, that Firefox (v71.0 64bit) does not turn the rad grid into edit mode, whereas IE11, Edge, Chrome (v78) perfectly work ok on the same grid?

Clicking the edit stencil button only makes the two arrows below rotate for some seconds, but nothing happens. What could that be?

Video Demo is attached.

Thank you,
Alexander

With no filtering applied, the filter menu still highlights the filter-function defined in the CurrentFilterFunction property of the column.
