As I know some events(like actionClick and collapse) and some Configuration(like collapse, alterningMode) are not working if I use custom template.

Is it a bug or not? 

Thanks,

Nurbek A.

I have a grid, which has few columns. While filtering, columns other than date column are picking distinct values as part of the filter. But, when it is date, it is not picking the distinct values. So, is there any way using which the unique dates can be picked and displayed in the filter?

Hi,

We are seeing an issue with new Kendo upgrade (2020). There are 2 scenarios that we have found that Kendo grid pagination is not working.

Scenario 1 : 

Kendo pagination doesn't work on the pageload, but it starts working when I click F12 to inspect the elements. It was working fine with the old version (2017). Below is the source code for the Grid.

  @(Html.Kendo().Grid<vm>()
                                                            .Name("id")
                                                            .Columns(columns =>
                                                            {
                                                                columns.Bound(d => d.FirstName).Title("First Name").Width(150);
                                                                columns.Bound(d => d.LastName).Title("Last Name").Width(150);
                                                                columns.Bound(d => d.MemberAddress).Title("Address");
                                                                columns.Bound(d => d.MemberDOB_STR).Title("DOB").Format("{0:MM/dd/yyyy}").Width(100);
                                                                columns.Bound(d => d.MemberId).Title("Member ID").Width(140);
                                                                columns.Bound(d => d.ZipCode).Title("Zip Code").Width(120);                                                                
                                                            })
                                                            .ToolBar(tools => tools.Excel())
                                                          .Excel(excel => excel
                                                          .Filterable(true)
                                                            .Filterable(filterable => filterable.Extra(false).Operators(operators => operators.ForString(str => str.Clear().StartsWith("Starts with").IsEqualTo("Is equal to").IsNotEqualTo("Is not equal to"))))
                                                            .Scrollable(s => s.Height("200px"))
                                                            .Pageable()
                                                             .Resizable(resize => resize.Columns(true))                                                      
                                                            .Sortable()
                                                            .DataSource(dataSource => dataSource
                                                            .Ajax()
                                                             .Sort(s => s.Add("MemberId").Descending())
                                                            .PageSize(10)
                                                            .Read(read => read.Action("Some Action", "Controller").Data(""))
                                                        ).AutoBind(false)
            )

 

Scenario 2: 

 

In this case the pagination doesn't even work . The same was working fine with the old verison.

 

  @(Html.Kendo().Grid<DiagnosisICDVM>()
                            .Name("grdMemberDiagnosis")
                            .Events(e => e.DataBound("DisplayDataMessageMemberDiagnosis"))
                            .Columns(columns =>
                            {
                                columns.Bound(d => d.CDCode).Title("Code").Width(100);
                                columns.Bound(d => d.Description).Title("Diagnosis").Width(250);
                                columns.Bound(d => d.CodeVersion).Title("ICD Version").Width(120);
                                columns.Bound(d => d.ICDStartDate).Title("Start Date").EditorTemplateName("date").Format("{0:MM/dd/yyyy}").Width(120);
                                columns.Bound(d => d.ICDEndDate).Title("End Date").EditorTemplateName("date").Format("{0:MM/dd/yyyy}").Width(120);
                                columns.Bound(d => d.SourceType).Title("Source").Width(120).HtmlAttributes(new { title = "#=SourceType#" });
                            })
                            .ToolBar(tools => tools.Excel())
                                  .Excel(excel => excel
                                  .Filterable(true)
                        .Pageable(p => p.PageSizes(true).Refresh(true))
                        .Resizable(resize => resize.Columns(true))
                        .Sortable()
                        .Scrollable()
                    .DataSource(dataSource => dataSource
                        .Ajax()
                        .Sort(s => s.Add("CDCode"))
                        .PageSize(100)
                          .Model(model => { model.Id(p => p.CDCode); })
                        .Events(events => events.Error("error_handler"))
                        .Read(read => read.Action("Some Action", controller).Data("JSFunction")))
        )

Bootstrap 3 and JQuery 1.12.4 being used as per the Kendo recommendation.

Please help in resolving this issue as we are close on the deadlines.

 

Thanks

Hello,

I'm using the following custom code for tooltips:

01.$('#' + tooltipContainerDivId).kendoTooltip({
02.    filter: filter,
03.    position: 'right',
04.    animation: {
05.        open: {
06.            effects: 'fade:in',
07.            duration: 200
08.        },
09.        close: {
10.            effects: 'fade:out',
11.            duration: 200
12.        }
13.    },
14.    // Show tooltip only if the text of the target overflows with ellipsis.
15.    show: function() {
16.        var cWidth = computeElementWidth(this.content, tooltipWidthWorkaroundDivId);
17.        if (this.content.text().trim() !== '') {
18.            $('[role="tooltip"]').css({
19.                width: cWidth + 10,
20.                visibility: 'visible'
21.            });
22.        }
23.    },
24.    hide: function() {
25.        $('[role="tooltip"]').css('visibility', 'hidden');
26.    },
27.    // Apply additional custom logic to display the text of the relevant element only.
28.    content: function content(e) {
29.        var $element = $(e.target[0]);
30.        var cWidth = computeElementWidth($element, tooltipWidthWorkaroundDivId);
31.        var dataTooltipAttr = $element.attr('datatooltip');
32. 
33.        if (cWidth > $element.width() || dataTooltipAttr) {
34.            // Text was truncated, or we have a custom tooltip message.
35.            if (dataTooltipAttr) {
36.                return dataTooltipAttr;
37.            }
38. 
39.            return e.target.text();
40.        } else {
41.            return '';
42.        }
43.    }
44.});

The main reason for this is to display tooltip only if the text would be too short to fit within a grid cell.

This is working fairly well, the only major problem that we have with this is that the little arrow indicator is sometimes not aligned properly. If I remove this custom code, the arrow is always correctly aligned. I assume that internally there is some code that positions the arrow based on the box that kendo builds, but since I resize this box, the arrow is then positioned incorrectly.

What would be the proper way to solve my problem ? Is there already a way to perform the behaviour that I want ? the thing is there are also some cases where we always want to display the tooltip because it contains extra information not displayed in the cell, so I think that either way we need custom code.

Is there a way to override the way the arrow position is computed ?

As we can see on both the attached screenshots, the arrow's position is in both cases not quite right, and it seems to depend on what element I hovered previously, if I hover the element above I get something, and if I hovered the element below I get something else when I come back to that element from the attached screenshot.

Thanks !

In this demo:

http://demos.telerik.com/kendo-ui/bar-charts/column

There is a legend on the top of the chart. If you click on one of the series in the legend, that data in the chart is not visible. Is there a way to programmatically do this? I want to provide this feature via an edit popup.

Thanks,

Hello-

In release v2013.2.918 we were taking advantage of the chart's legendItemClick default functionality of hiding series on a click event.

We also had some add'l buttons on our page that we tied in to this functionality to programmatically trigger the legendItemClick with a simple:

$('legend-item-element').click()

and the user could click these other (non-Kendo) buttons and show/hide chart series. This worked great - see this fiddle:

http://jsfiddle.net/gtP55/


Since the last release, we can no longer successfully call $('legend-item-element').click(). The click event is not properly triggered programatically. Is there any way to do so? This functionality is heavily enmeshed in our page now and users are expecting it.

Thanks!

Below is my coding.

Here i want to do a if condition in "Comments" column. if comments available then i need to replace it as "1". if its empty then "0".

1. Either i can introduce new column at the end and apply the above condition and hide the "Comment" column (as this value depend on child row)

2. or directly modify the comment column

 

<div id="grid"></div>
                    <button id="btnprint" type="submit" name="excel" value="valexcel">Print</button>
<script> $("#grid").kendoGrid({ columns: [{ field: "productName" }, { field: "category" }, { field: "status" }, { field: "Comments" }], dataSource: { data: [{ productName: "Tea", category: "Beverages", status: "Open", "Comments": "" }, { productName: "Coffee", category: "Beverages", status: "Open", "Comments": "comment1" }, { productName: "Ham", category: "Food", status: "Open", "Comments": "" }, { productName: "Bread", category: "Food", status: "Open", "Comments": "" }, { productName: "Hammer", category: "Hardware", status: "Closed", "Comments": "Comment test" }, { productName: "Screw", category: "Hardware", status: "Open", "Comments": "commenting testing" }], group: { field: "category" } },  detailTemplate: "<div class='Comments'>",
                    detailInit: function (e) { e.detailRow.find(".Comments").html("<p>" + e.data.Comments + "</p>"); }, });</script>

I am working with the grids, and I would like to hide the detail grid and indicator when the the datasource returns empty.  Looking through the forums, I found the suggestion of 

"After the grid is populated(i.e DataBound event is triggered) you can remove the css class for desired.k-master-row>.k-hierarchy-cell>a element. That is the only way to hide the expand/collapse arrow"

Can someone point me to a code sample where this is working?  This seems like something that I would need to do inside the detail grid, but I cannot figure out where.  Below is my function in case it is needed.

Thanks for your help.

function detailInit(e) {
    $("<div/>").appendTo(e.detailCell).kendoGrid({
        dataSource: {
            type: "json",
            transport: {
                read: "/DashController/GetMoreReports?Id=" + e.data.ReportId
            },
            serverPaging: true,
            serverSorting: true,
            pageSize: 10,
        },
        scrollable: false,
        sortable: true,
        pageable: true,
        columns: [
                            {
                                template: '<a href="/ReportId=#=ReportId#">#=ReportNumber#</a>',
                                title: "Report"
                            },
                            {
                                field: "Summary"
                            }
                        ]
    });

 i have the following coding.  I want to print this as it is in a button click ( with same color, styles etc..)

 

<div id="grid"></div>
                    <button id="btnprint" type="submit" name="excel" value="valexcel">Print</button>
<script> $("#grid").kendoGrid({ columns: [{ field: "productName" }, { field: "category" }, { field: "status" }, { field: "Comments" }], dataSource: { data: [{ productName: "Tea", category: "Beverages", status: "Open", "Comments": "" }, { productName: "Coffee", category: "Beverages", status: "Open", "Comments": "comment1" }, { productName: "Ham", category: "Food", status: "Open", "Comments": "" }, { productName: "Bread", category: "Food", status: "Open", "Comments": "" }, { productName: "Hammer", category: "Hardware", status: "Closed", "Comments": "Comment test" }, { productName: "Screw", category: "Hardware", status: "Open", "Comments": "commenting testing" }], group: { field: "category" } },  detailTemplate: "<div class='Comments'>",
                    detailInit: function (e) { e.detailRow.find(".Comments").html("<p>" + e.data.Comments + "</p>"); }, });</script>

I tried with the following link and cannot achieve this.

https://docs.telerik.com/kendo-ui/controls/data-management/grid/export/print-export

-- I can achieve this by converting this grid to pdf and print it. But i dont want to do it and want to print this directly

Expecting your help.

Hi,
I'm trying to create an Arc Gauge with a centerTemplate that won't use "value". The centerTemplate is going to display percentage of RAM and the actual RAM used (see attached image).
If I were to only show the percentage, it wouldn't be any problem.
Currently, my code for the Arc Gauge looks like this:

@(Html.Kendo().ArcGauge()
    .Name("MemoryBar")
    .Value(Model.CurrentMemoryPercent)
    .Scale(x => x.Min(0).Max(100))
    .CenterTemplate(string.Format("{0}% ({1})", Model.CurrentMemoryPercent, size))
)

That just creates a static CenterTemplate, though, and none of the variables are updated unless I refresh the page.

I can kinda work around this by using setoptions, but that redraws the entire gauge and forces me to disable transitions, which I don't want to.

Am I missing something completely, or can't this be done properly?

Thanks for any help.
