Change / remove bar chart bar border, plot area border

Is there a way to remove or change the color of the border that is rendered on the right side of the plot area?

Similarly, is there a way to remove or change the color of the border that is rendered on the right side of a bar chart bar?

I can see the SVG elements that draw them but I can't find a way to change the color.

I've attached a picture with red arrows pointing at the elements I'm asking about.

[Solved] Reference Grid Element from rowTemplate methods

I have dynamically created, unpredictable (but always valid) kendo object .

Inside this object, there will sometimes be a rowTemplate method.

This object is then passed through a functionA that makes a few changes to the object (assigning default values etc.) before being passed into (sometimes) multiple kendogrids.

However, a problem arises when the rowTemplate method needs to reference the kendo grid element that it exists inside:

The parameters for rowTemplate only include the dataItem, which has no reference to the grid element or any of it's children and as the kendo object is created outside of where it is passed in to the kendo grid elements I have no scope to the grid element nor any ID it may have.

I've tried looking at the arguments to check to see if there are any extra parameters that I'm missing and there are none.

I have checked the value of this and it seems to evaluate to window.

Event is also not something I think that I can make use of.

https://dojo.telerik.com/ATesALoM/2

Two workarounds that I have thought of:

I could potentially attach a field when editing the object in functionA that is equal to the value of the to-be-created grid's ID and the grids can make use of this column in order to reference the kendo element.

The other workaround would be to (from functionA) programmatically loop through the object in search of any function and to bind those functions to the grid element, then simply have those functions assume that "this" will always be equal to the kendo grid element.

Both of these workarounds have drawbacks and I would rather only use them as a last resort.

Is there is something I am missing that would greatly simplify this?

If you require any clarification or examples needed please let me know and I'll provide them.

MVVM Sample for TileLayout

Hi - we use MVVM binding al lot in our kendo application.

Are there any samples / help pages that list the attribute names to use when declaring a TileLayout in MVVM style ?

Something similar to the information presented on this page: https://demos.telerik.com/kendo-ui/mvvm/widgets

Regards

[Solved] No format if value is below minimun

I have this code below

$("#numeric").kendoNumericTextBox({
min: 1,
max: 100,
decimals: 0,
format: "# pieces",
spinners: true,
restrictDecimals: true
});

My problem is that if user enter "0", then tab out, value changes to "1" only, not "1 pieces"

So it does not follow the format if the entered value is below the min. No problem if value is more than max.

My version is "2018.3.1017", upgrade is not an option.

Do you have a workaround on how to force to change the display value with format (may be on the onblur event perhaps)?

Grid DataKeys Setup

good morning everyone,

I am currently using the licensed version of Kendo UI Complete for ASP.NET MVC (Q2 2012) and trying to figure out if the Kendo UI Grid has something similar to the DataKeys method in the Telerik Extensions for ASP.NET MVC Grid?

Before this, I was using the licensed version of Telerik Extensions for ASP.NET MVC. Below is the code I had for it. You'll notice, there is a "DataKeys" method which I can associate the "Id" property of the Model, to each row of the Grid.

@{Html.Telerik().Grid(Model)

.Name("grdAllUsers")

.DataKeys(keys => keys.Add(k =>

k.Id)

)

.Columns(columns =>

{

columns.Bound(o => o.FirstName)

.Width(150);

columns.Bound(o => o.LastName)

.Width(150);

columns.Bound(o => o.EmailAddress)

.Width(200);

.Width(70)

.HtmlAttributes(new { style = "text-align:center" });

})

.NoRecordsTemplate(@<text>No User records to display.</text>)

.Pageable(paging =>

paging.PageSize(15)

)

.Sortable()

.Filterable()

.Render();

}

Is there something similar in the Kendo UI Grid??? Below is my current Kendo UI Grid.

@{Html.Kendo().Grid(Model)

.Name("grdAllUsers")

.Columns(columns =>

{

columns.Bound(o => o.FirstName)

.Width(150);

columns.Bound(o => o.LastName)

.Width(150);

columns.Bound(o => o.EmailAddress)

.Width(200);

.Width(70)

.HtmlAttributes(new { style = "text-align:center" });

})

.Pageable(paging =>

paging.PageSize(15)

)

.Sortable()

.Filterable()

.Render();

}

Thank you very much for your help.

TileLayout - Pie Chart labels are cut off

Hello,

we have a TileLayout with a Pie Chart inside. The Pie Chart is diaplaying labels.

Unfortunately when the tile size is reduced, the labels are cut off (horizontally and vertically).

Is there any way to prevent this.

Example:

Reduce the width of the Pie Chart in this dojo: https://dojo.telerik.com/EsOWoqAL

Uncaught TypeError: e.slice is not a function on data fetch

Hi!

I'm trying to make an ajax call to my controller function.
To get all the data that currently are in a grid's datasource.
Instead of calling directly to the grid's datasource.data() which only returns me the current grid page.

I go about this by instantiating a new kendo datasource.
But everything i try, yields "Uncaught TypeError: e.slice is not a function"

Thanks in advance.

public JsonResult ReadTimeRegistrationAjax([DataSourceRequest] DataSourceRequest request)

{

var dataSourceResult = getStuff().ToList();

return Json(dataSourceResult.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

var grid = $("#GridTimeRegistrations").data("kendoGrid");

var dataurl = grid.dataSource.transport.options.read.url;

var dataSource = new kendo.data.DataSource({

transport: {

read: {

url: dataurl,

dataType: 'json'

}

},

});

dataSource.fetch(function() {

var data = dataSource.data();

console.log(data);

}

Reorder problem in kendoTilesLayout

I have an issue and I need someone to see what I'm doing wrong...

I tried to use several times "reorder". I simplify the test to this :

<script id="barcelona" type="text/x-kendo-template">

A

</script>

<script id="sofia" type="text/x-kendo-template">

B

</script>

$("#home-super-container").kendoTileLayout({

containers: [{

colSpan: 1,

rowSpan: 1,

header: {

text: "Barcelona"

},

bodyTemplate: kendo.template($("#barcelona").html())

}, {

colSpan: 1,

rowSpan: 1,

header: {

text: "Sofia"

},

bodyTemplate: kendo.template($("#sofia").html())

}],

columns: 2,

columnsWidth: 285,

rowsHeight: 285,

reorderable: true,

reorder: function (e) {

console.log(e.newIndex, e.oldIndex);

}

});

The console.log indicates (0 0), it should be (0 1) or (1 0)...

Change grid column template with button click

Hi,

I have a kendo toolbar with multiple dropdowns and checkboxes to filter my datasource. What I want is when I submit my filter selections, if a spesific checkbox is checked, then datetime column of the grid will have this template:

"#= kendo.toString(kendo.parseDate(dates), 'dd/MM/yyyy') #"

If the checkbox not checked (or the page is just loaded with empty checkbox in default scenario) the column will have:

"#= kendo.toString(kendo.parseDate(dates), 'dd/MM/yyyy HH:mm') #"

as template.

I tried conditioning inside of grid but I didn't manage to obtain checkbox value. I tried writing a function outside the grid function but when I refresh grid data with:

var grid = $("#grid").data("kendoGrid");
grid.dataSource.data(reportData);

it only refresh the data inside grid, that does not trigger the template function.

How can I change the column template while refreshing the data according to that checkboxs value?
