The details for this can be found in ticket #1519224

Given some XML that has child nodes and attributes, I'm binding to a grid with no problem. The child grid for each row (built using detailInit) get's the data from the parent row e.data.get("BillRows")

If those rows have attributes, the '@' signs breaks the javascript for the grid. As you can see in the ticket, every attribute needs to be renamed before I can build the child grid.

Should be a way to use attributes in XML bound to a datasource/grid for all levels of grids.

Bug report

When the Grid has no data, a horizontal scrollbar appears.

Reproduction of the problem

Run the Dojo - https://dojo.telerik.com/cwVUBcpz

Current behavior

There is a redundant scrollbar.
When there is a record in the same Grid, the scrollbar does not appear.

Expected/desired behavior

There should be no scrollbar when the columns have no width set and the Grid has no data.

Workaround

Bug Report

When the Grid is exported with child columns hidden with Multi-column headers, the columns headers are not exported.

Reproducible

1. Go to this Progress Kendo UI Dojo
2. Export the Grid

Current Behavior

The column headers do not all export:

Expected Behavior

The Grid should export all column headers like when they are not hidden - Dojo :

Workaround

Explicitly set the parent column's exportable configuration to true - Dojo:

$("#grid").kendoGrid({
    columns: [
        { field: "name", title: "Name" },
        {
            title: "Address",

            columns: [
                { field: "street", title: "Street", hidden:true, exportable: true },
                { field: "city", title: "City", hidden:true, exportable: true }

I am creating a grid from a table data source rather than an endpoint call. Other pages that use endpoints to populate the datasource export Excel with no problems.

Example HTML:

<table class="table table-responsive" id="tblReportSummary">
<colgroup>
<col />
<col />
<col />
<col />
<col />
</colgroup>
<thead>
<tr>
<th data-field="date">Date</th>
<th data-field="totalForStatus">Count</th>
</tr>
</thead>
<tbody>
@foreach (var item in ViewBag.ReportDataSummary as IEnumerable<UtilizationListViewModel>)
{
<tr>
<td>@item.Date</td>
<td>@item.TotalForStatus</td>
</tr>
}
</tbody>
</table>

The jQuery is as follows:

             $("#tblReportSummary").kendoGrid({
                sortable: true,
                toolbar: ["excel"],
                excel: {
                    allPages: true,
                    fileName: "Utilization Data Export.xlsx"
                },
                pageable: {
                    pageSize: 20,
                    pageSizes: [20, 50, 100]
                }
            });

When I click Export, all I get is an empty Excel file.

Why isn't the data there, please?

If you configure a Kendo Grid with client-side paging, each time you call setDataSource to update the data source then a new .k-pager-numbers-wrap DIV is added to the page controls. I've replicated the problem in Dojo at https://dojo.telerik.com/UTolOzer by taking a basic client-side paging demo, moving the dataSource configuration into a separate function (with data("kendoGrid").setDataSource), and calling that function 25 times. At the end, the source shows the UL element with the page buttons inside 25 .k-pager-numbers-wrap DIV elements.

I first noticed this problem because in my own environment, each nested DIV was shifting the page buttons left 1 pixel and overlapping the "previous page" buttons. In my Dojo example, with 25 nested DIVs the page buttons disappear completely.

I've added the following in my own code as a workaround in the dataBound event of the grid:

                            var trueParent = e.sender.pager.element.find(".k-pager-numbers-wrap").first();
                            e.sender.pager.element.find("ul").appendTo(trueParent);
                            trueParent.find(".k-pager-numbers-wrap").remove();

Hi, 

Here is the dojo to reproduce. In this dojo I've created imitation of data, that coming from server in our case. The main idea is to have a grid with lazy loading - it has 10 groups (page 1) and after scrolling down it loads 10 more groups (page 2) and etc.

Issue 1. 

After scrolling down, data from the last group is updated with some data, that is not belongs to it. Please see 'Issue1.png' attached.

Issue 2.

Groups from the first page are duplicated after scrolling down. For example, there is a group named 'C3'. After scrolling down, it is duplicated once again. Please see 'Issue2.png' attached. New groups are placed after these duplications. By the way, as groups from the 1st page are duplicated, there is more than 20 groups is shown, but the counted at the bottom of the grid says that '20 of 137' elements are show.

So it would be great, if you could fix that. Or even provide temporary fix for us.

Thank you!

Hello guys,

I am stuck with this problem for some time now. Everything works well with mouse, I can drag and drop column into grouping header normally. But on touchscreens I can't drag it. I am interested if anyone has had this issue?

Hi,

Bring up an RTL kendo Grid which has resizable true and filter mode is "row".

then try to resize the grid from filter-row of grid. we will see an internal js error.

you can copy and paste this code in a dojo sample and resize grid from the point is shown in the attached picture.

Hello, the Excel Export doesn't export the columns headers sums (view in image).

Is it possible export to Excel columns headers sums?

Bug report

The row reordering functionality does not work correctly when the draggable column has a small width.

Reproduction of the problem

https://dojo.telerik.com/@user192/ipOyacoH

Open the Dojo and try to reorder a row. The icon inside the hint will keep changing and in some cases you won't be able to drop the row to the expected position.

If you move the hint a bit to the right(towards the next column) this behavior disappears.

Current behavior

The reorder hint shimmers and in some cases does not allow for reordering. This occurs when the column width is small(30px in the example).

Expected/desired behavior

Reorder should work as expected, regardless of the column width.

Bug report

When the selectable option is set to "multiple cell" and the user tries to select the content of a single column, the content of the entire row is selected.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/AzirANuT
2. Try to select the text in the France cell and drag down to select only the content in the ShipCountry column.

Current behavior

The content of the other columns is selected as well - https://somup.com/cZeXIvpRzk

Expected/desired behavior

The behavior is expected when the allowPaste option is enabled. However, once the allowPaste option is disabled only the content of the selected column should be selected.

Workaround

kendo.ui.Selectable.fn._allowPreventDefault = () => true;
