Release 2019.R3.SP.next

Bug report

If the CurrentTimeMarker is enabled (it is by default), the resources are grouped, and events with different resource values (about 70) are loaded for the current day, a significant performance deterioration is observed.
With the CurrentTimeMaker disabled or the events loaded for a date different than today (past or future) the performance issue is not exhibited.

Reproduction of the problem

MVCSchedulerCurrentTimeMarker.zip

  1. Run the attached sample project.

Current behavior

No exceptions are thrown, but the Scheduler becomes unresponsive.

Expected/desired behavior

There should be no performance hit, regardless of CurrentTimeMarker being enabled/disabled.

How can I fix this problem?

Hi,

I'm experiencing a bug with the kendo grid. In my project I have a rather complicated website where a kendo grid is loaded depending an multiple criteria which can be chosen by the user through dropdowns and multiselects. Luckily, I could break it down to a simple test website and the bug still is bugging around ;)

Description: Depending on the criteria chosen, the grid loads different data which reach from zero to thousands of data rows. In my example here, it's either zero or 100 data rows (depending on the dropdown, if there is either "Empty" or "Not empty" selected). The grid loads its data if you press the button ok (by calling the Load action on the server). The result is meant to be limited to paging of 25 rows (no user choice wanted)!

Heres the code for the cshtml site:

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <div id="content">
        <div>
            @(Html.Kendo().DropDownList()
                            .Name("test_selector")
                            .DataTextField("Display")
                            .DataValueField("Value")
                            .BindTo(new List<DropDownVM>() {
                                            new DropDownVM()                                                                    {
                                                Display = "Empty",
                                                Value = "empty"
                                            },
                                            new DropDownVM()                                                                    {

                                            .Columns(columns =>
                                            {
                                                columns.Bound(x => x.TestId).Title("TestId").Width(75);
                                                columns.Bound(x => x.TestName).Title("TestName").Width(75);
                                            })
                                            .Sortable()
                                            .Pageable()
                                            .DataSource(dataSource => dataSource
                                                .Ajax()
                                                .PageSize(25)
                                                .Read(read => read.Action("Load", "Test").Data("GetSelectorData"))
                                            )
                                            .AutoBind(false) //Do not load Grid data initially
            )
        </div>
        <div>
            @Html.Kendo().Button().Name("Load").Content("Load")
        </div>
    </div>
    <script type="text/javascript">
        $("#Load").on("click", function (e) {
            var grid = $("#grid_Test");
            grid.data("kendoGrid").dataSource.read();
        });

        function GetSelectorData() {
            var selectorData = {
                type: $('#test_selector').data("kendoDropDownList").value()
            }
            return selectorData;
        }
    </script>
</body>
</html>

And the corresponding controller:


public class TestController : BaseController
    {
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult Load([DataSourceRequest] DataSourceRequest request, string type)
        {
            List<TestItem> result = new List<TestItem>();
            if (type == "notEmpty")
            {
                for (int id = 1; id <= 100; id++)
                    result.Add(CreateTestItem(id));
            }

            request.PageSize = 25;
            return Json(result.ToDataSourceResult(request));
        }

        private TestItem CreateTestItem(int id)
        {
            TestItem result = new TestItem()
            {
                TestId = id,
                TestName = "Name" + id
            };
            return result;
        }
    }

Problem: The scenario described above works actually fine as long as the grid gets at least one data row delivered as DataSourceResult (i.e., result.Count > 0 in the Load method of the controller). The request object in the controller's Load method also shows request.PageSize to be configured to 25. Also, if I choose "Empty" from the dropdown and press the Load-button, the request in the controller will show PageSize = 25. But if I switch the selector to "Not empty" afterwards and press Load, the request will show PageSize = 0! This results in the grid not being paged at all and showing all results on a single page (which leads to serious connectivity problems in my productive project as soon as there are several thousands of data rows).

I tried a quick workaround in the Load method of the controller by setting the PageSize manually back to 25 (which is not wanted of course, but would actually work for me at the moment):


public ActionResult Load([DataSourceRequest] DataSourceRequest request, string type)
        {
            List<TestItem> result = new List<TestItem>();
            if (type == "notEmpty")
            {
                for (int id = 1; id <= 100; id++)
                    result.Add(CreateTestItem(id));
            }

            request.PageSize = 25;
            return Json(result.ToDataSourceResult(request));
        }

Unfortunately, this doesn't work either. The paging will be back on again and there will be only 25 data rows loaded in the grid but there is only one single page no matter how many data rows are loaded (see attached screenshot).

Do you know about this? Unfortunately I couldn't find any help for this problem so far.

Greetings!

Bug report

ComboBox with filtering option set to "contains".

Search for the last element in ComboBox dropdown and select it. Delete the selected item with mouse selection and "Delete" button. The dropdown will open again. Select the first element in the dropdown. It will close and no data will be selected. If we repeat the scenario and instead of selecting the first element, we select another one, everything is working properly.

This is regression introduced in 2018 R1 SP1

Reproduction of the problem

  1. Open this Dojo and run it
  2. Select the ComboBox and enter "rib", then select "Rib Knit"
  3. Unfocus the ComboBox and then focus it again
  4. Using the mouse select the "Rib Knit" text and delete it. The dropdown of the ComboBox will open.
  5. Select the first element "Cotton".
  6. The dropdown closes and no item is selected

Current behavior

Hi,

I notice that some of the styling has changed for the Blue Opal theme in the latest release (2019 R1), notably the background colour of the selected page on the grid and the already selected items on a Drop Down List have gone from dark blue to a bright blue (see attached screenshots from demos.telerik.com).

Is this by design or by mistake?

Particularly on the drop down list, this change makes it more difficult to identify the already selected items.

Can this go back to what it used to be - or is there a way of manually changing this setting via the site.css?

Thanks

Kevin

It would be nice to have a MultiColumnComboBox as we have it already in WinForms.
A MultiColumnComboBox is a special case of combo box control with Grid integrated in its drop-down. The control combines the functionality and features of DropDownList and Grid.

It would be great to have the ability to have to conditionally set behavior for columns and buttons.

On a Grid with this:
.Columns(columns =>
{
  columns.Bound(b => b.IsEditable).Hidden(true);
  columns.Bound(b => b.Id);
  columns.Bound(b => b.Description).Width(200);
  columns.Command(c=>
        {
              c.Edit();
        });
})

Today if I want to hide a button depending on a cell value I need to do it on databound event.
It would be great to have the option to set something like:
command.Edit().Display(p => p.IsEditable); 

For a column, it would be nice to have something like:
columns.Bound(b => b.Description).Width(200).Editable(p => p.IsEditable);

Ponder? its a basic usability Feature, Kendoui is supposed to be all about usability, surely this is Ponder? There should be a standard (easy/inbuilt) way to show that a grid data source has no records because that is the default opposite to a populated data grid. at the very least if data is empty then show "nothing" all mine does is leave the spinning ajax wheel running forever, so end users does not know, this means i have to write extra code just to implement this, so please consider this "feature"

Since the new grid only works with kendo validator, it is important to support all the same jquery validate features that work seamlessly with MVC. The old telerik grid worked just fine with remote validation.

KendoUI MVC Serverside wrappers should allow exporting grid data to PDF, Excel and CSV. While this has been asked for before, what I am asking is that this feature be part of the KendoUI complete with server side wrappers so that this is no longer just a limitation with the client-side framework. Every business application we have with grids requires the ability to export in PDF, Excel and CSV formats.

Nowadays, was promissed exporting Gantt to PDF.
It is not working. Just prints what you see. It is very limited.
Should allow: 
1)  option like "allPages" to print all Gantt Diagram in any page format.
Making a "printscreen" of the visible gantt it is any solution for any project. 


2) Export Gantt data to excel.
