TreeList with groupable header columns

Hey Folks,

is it possible to achieve the same functionality that the grid component offers ( groupable header columns ) in the TreeList? The documentation does not mention something like that and i did not get it to work.

Is my only option to use the grid component with dynamic subgrids?

Filter and sort string columns as Date

Hello,

I have a grid and the data I receive is in string, even for my 2 date columns. I was able to change them in the preferred Date format, but I can't seem to get the filter and sorting working.

I tried to change the datatype of the columns to datetime, but that was unsuccesfullI

I'm now looking for some help to create a custom filter (and sort) so that I can sort and filter my date columns the correct way.

It's a pretty complicated solution, but here's some of the code were I load my grid:

function loadGrid(userGridSettings) {

var gridSettings = {

selectable: "multiple row",

sortable: true,

filterable: true,

pageable: {

refresh: true,

pageSizes: [10, 20, 50, 100],

buttonCount: 5

},

resizable: true,

columnMenu: true,

toolbar: kendo.template($("#searchgrid-toolbar").html()),

editable: "popup",

reorderable: true,

columnHide: saveState,

columnShow: saveState,

columnResize: saveState,

columnReorder: saveState,

columns: [{

field: "IsSelected",

title: null,

sortable: false,

filterable: false,

width: 25,

menu: false,

reorderable: false

}, {

field: "BatchName",

title: "Batchnaam",

filterable: { multi: true }

}, {

field: "RequesterPartyRequired",

title: "Kabelsel.",

filterable: { multi: true }

}, {

field: "StartDate",

title: "Plandatum start",

type: "date",

format: "{0: dd-MM-yyyy}",

filterable: {

ui: function (element) {

element.kendoDatePicker({

format: '{0: dd-MM-yyyy}'

})

},

multi: false

}

}, {

field: "EndDate",

title: "Plandatum eind",

type: "date",

format: "{0: dd-MM-yyyy}",

filterable: {

ui: function (element) {

element.kendoDatePicker({

format: '{0: dd-MM-yyyy}'

})

},

multi: false

}

}, {

field: "ID",

title: " ",

filterable: false,

sortable: false,

width: 25,

menu: false,

reorderable: false

}]

};

var customFields = [{

field: "IsSelected",

template: "<input type='checkbox' class='checkbox' #= IsSelected !== undefined && IsSelected ? checked='checked' : '' # />",

headerTemplate: "<input type='checkbox' id='checkAll' />"

},

{

field: "StartDate",

filterable: {

ui: function (element) {

element.kendoDatePicker({

format: '{0: d-M-yyyy}'

})

},

operators: {

string: {

eq: "Is gelijk aan",

neq: "Is niet gelijk aan"

}

},

multi: false

},

format: '{0: d-M-yyyy}'

},

{

field: "EndDate",

filterable: {

ui: function (element) {

element.kendoDatePicker({

format: '{0: d-M-yyyy}'

})

},

operators: {

string: {

eq: "Is gelijk aan",

neq: "Is niet gelijk aan"

}

},

multi: false,

},

format: '{0: d-M-yyyy}'

},

{

field: "ID",

template: "#=actionTemplate(data)#"

}];

if (userGridSettings !== undefined && userGridSettings !== "" && userGridSettings !== null && JSON.stringify(userGridSettings) !== "{}") {

gridSettings.columns = userGridSettings;

}

$.each(customFields, function (customFieldIndex, customField) {

$.each(gridSettings.columns, function (columnIndex, column) {

if (column.field == customField.field) {

if (customField.sortable) {

column.sortable = customField.sortable;

}

if (customField.template) {

column.template = customField.template;

}

if (customField.headerTemplate) {

column.headerTemplate = customField.headerTemplate;

}

if (customField.filterable) {

column.filterable = customField.filterable;

}

});

searchGrid = $("#searchGrid").kendoGrid(gridSettings).data("kendoGrid");

searchGrid.thead.find("[data-field=IsSelected]>.k-header-column-menu").remove();

searchGrid.thead.find("[data-field=ID]>.k-header-column-menu").remove();

}

Find grid row from embedded chart click

Hi,

I have a grid with an embedded bar chart. The bar chart is firing a seriesClick() event.
How can I find the grid row containing the chart that fired the event?

Prototype is in this snippet copied from the embedded chart demo. Just click in any bar of a chart.

Thanks in advance,

Multi filter with null values - they are not visible

Hi,

In my grid there are cells where we can accept having null values, e.g. property can exist without owner. I would like to filter owner column in multifilter by having null. Right now, empty (null) values are not visible in multi filter menu, only existing owners are displayed. We hacked the problem by switching from null values to empty strings "", and they are visible in menu. But I'm feeling extremely awful for doing such hacks in my code.

I checked that it's made like that because in FilterMultiCheck _init function you got such line:

FilterMultiCheck

_init: function () {

...

this.checkSource.data(distinct(this.dataSource.data(), this.field));

...

And the distinct function looks like that:

function distinct(items, field) {

...

if (text !== undefined && text !== null && !seen.hasOwnProperty(text)) {

result.push(item);

seen[text] = true;

}

...

You see, that null and undefined values are omited and they are not the part of the results. Unfortunately, removing the null & undefined conditionals don't work - null is showed in menu but you cannot filter by it.

Will you be able to do something with it in the future? Right now i can workaround it, but it's really nasty to replace nulls with empty strings :)

How to pass string as a argument in a Template

How can I pass a string with single quote in a Kendo grid template -

In the below code I have a function confirmDelete which expects a string argument, in the example I am passing id (encrypted string) but when I add the single quote around it the HTML rendering fails. If I pass just id with no quotes AngularJs throws a error.

This may not be the right forum but I have not got response from the Kendo Lab, i will appreciate your help.

k-columns='[
{ "field": "firstName", sortable:true, "title": "First Name"},
{ "field": "lastName", sortable:false,"title": "Last Name"},
{ "field": "middleName", sortable:true,"title": "Middle Name"},
{ "field": "id", sortable:true,"title": "Id"},
{ "template": "<a href=\"Constituent/Detail/#: id#\">Edit</a><a href=\"\" ng-click=\"confirmDelete('\"+id+\"')\">Delete</a>", "title": "Actions" }]'

Kendo MVVM Template - Not binding Correctly

Hi,

I am trying to bind kendo template with MVVM but unfortunately facing some weird issue. My JSON looks correct but the template is binding the data incorrectly. What's interesting is if I comment either Dropdown or Span, the other control works perfectly. I tried assigning a unique Ids to control but it's not helping. Could you please check below fiddle?
