Hi,
Is there a way to instantiate a blank NumericTextBox when editting a "Number" field who's value is 0?
In other words, if I have numeric fields in my grid and their value is 0, I want to show the 0 on the grid. And when the user edits the field, I'd like to a NumericTextBox to show with no value. If the user does not give a new value, and 'blurs' the text box, the underlying value in the text box does not change.
Currently, when I edit a number who's value is 0 or null, the 0 shows in the text box. I just think it would be a better user experience if the 0 disappeared when editing the value.
Here is my attempt at such an editor. This is not working since this code will change the datasource value to null if textbox is left blank, which triggers the grid save event, and a whole host of other things.
$('<input class="text-right" name="' + options.field + '"/>')
.appendTo(container)
.kendoNumericTextBox({
decimals: 0,
format: 'n0',
step: 1,
spinners: false
}).off("keydown").on({
'focus': function () {
if (!$(this).val() == 0) {
$(this).val('');
console.log('huh?', this.value, $(this).val(), arguments);
}
},
'blur': function () {
if ($(this).val() == "") {
console.log('wha?', this.value);
$(this).val("0");
}
}
});

I'm working on a project that is using the kendoGrid and odata service with virtual scrolling enabled.
The data we are pulling into the the grid doesn't use a traditional id number for it's primary key, so to have something that looks like an id number in the table we created an id column and append the number via a column template, which looks like this.
let _columns = [{
field: 'rowNumberer',
title: '#',
template: '#= ++rowNumber #',
width: 30
}
So the issue we are having is that as you scroll down the page the number increments fine, but it's also increments when you scroll up which throws the count off.
Is there another way to handle this?

We have a simple grid having a the filters in a row. When the grid has a horizontal scrollbar, and the user is navigating using tab across the filters, only the header scrolls and not the body. Check the attached gif and below is its source code (which is a straightforward demo on Telerik):

I have the following in side an HTML page:
<!-- Template for simple search row --><script id="simple-search-row" type="text/x-kendo-template"> <div class="simple-search-row"> <input name="fieldName" data-role="dropdownlist" data-text-field="columnDisplayName" data-value-field="columnName" data-bind=" value: field, source: columnsDataSource"></input> <span data-for="fieldName" class="k-invalid-msg"></span> <input name="filter" data-role="dropdownlist" data-text-field="displayName" data-value-field="name" data-bind=" value: type, source: filterTypesDataSource, events: { change : criteriaChanged, dataBound : simpleSearchDDLDataBound }" style="width: 15em;"></input> <span data-for="filter" class="k-invalid-msg"></span> <input id="value-1" name="value-1" type="text" data-bind=" value: values[0]"></input> <span data-for="value-1" class="k-invalid-msg"></span> <span id="value-and" style="display: none;">#: translate('between_and') #</span> <input id="value-2" name="value-2" type="text" style="display: none;" data-bind=" value: values[1]"></input> <span data-for="value-2" class="k-invalid-msg"></span> <a href="\\\\#" data-bind="events: { click : removeSimpleSearchRow }"> <span class="k-icon k-i-cancel"></span> </a> <a href="\\\\#" data-bind="events: { click : addSimpleSearchRow }"> <span class="k-icon k-i-plus"></span> </a> </div></script><div id="simple-search-rows" class="ui relaxed grid" data-template="simple-search-row" data-bind="source: searchFilter.criteria"></div>
"searchFilter.criteria" is a JS array object. And then I have a custom validator:
var simpleSearchValidator = $('#simple-search').kendoValidator({ messages : { fieldname : '', filter : '', valueone : '', valuetwo : '' }, rules: { fieldname : function (input) { if (input.is('[name|=fieldName]')) { if(input.val() === ''){ return false; } } return true; }, filter : function (input) { if (input.is('[name|=filter]')) { if(input.val() === ''){ return false; } } return true; }, valueone : function (input) { if (input.is('[name|=value-1]')) { let filter = input.parent().find('[name|=filter]'), criteria = (filter ? filter.val() : ''); switch(criteria){ case 'EQUAL_TO': case 'NOT_EQUAL_TO': return true; } if(input.get(0).style.display === 'none') { return true; } if(input.val() === ''){ return false; } } return true; }, valuetwo : function (input) { if (input.is('[name|=value-2]') && input.is('')) { if(input.val() === ''){ return false; } } return true; } } }).data('kendoValidator');
The issue is that the validator's .validate() is called, it correctly identifies incorrect data based on the custom rule, however if say the fieldName input field is invalid, it displays the k-invalid-msg for EVERY row, not just the single row with the invalid data. I am guessing this is because the name attributes for each row are not unique. I tried creating a unique id in the template:
<!-- Template for simple search row --><script id="simple-search-row" type="text/x-kendo-template"> <div class="simple-search-row"> # var uid = windows.util.genUniqueId(); # <input name="fieldName#= uid #" data-role="dropdownlist" data-text-field="columnDisplayName" data-value-field="columnName" data-bind=" value: field, source: columnsDataSource"></input> .... </div></script><div id="simple-search-rows" class="ui relaxed grid" data-template="simple-search-row" data-bind="source: searchFilter.criteria"></div>
Unfortunately, that did not work as the uid was only created once, at the time the template was loaded, not for each row.
Is there an easy way to generate a unique form name for the input elements in each row?

A NumericTextBox used in Angularjs (v1.5.8) seems to swallow the click events.
The box is included like this:
<input kendo-numeric-text-box="numericTextBox" fc-numeric-box-placeholder k-spinners="false"
k-decimals="{{ ::decimals }}" k-options="numericBoxOptions" ng-model="value"/>
The options set the min and max values. The box itself works fine, updating values as expected.
If you have a dropdown opened (bootstrap) though, clicking inside the NumericTextBox will not close the dropdown. Clicking anywhere else closes it.
Is there a way to configure NumericTextBox to facilitate this behavior?

We have a requirement where, we are generating controls dynamically.
If I directly put this in html, then it’s working without any problem.
<textarea id="665" tabindex="1" class="rTFStyle" kendo-editor k-ng-model="richTextEditor_665" k-tools="['bold','italic','underline','strikethrough','justifyLeft','justifyCenter','justifyRight','justifyFull','insertUnorderedList','insertOrderedList','indent','outdent']"></textarea>
but if I use it with $compile then it is not working as expected
var html = “<textarea id="665" tabindex="1" class="rTFStyle" kendo-editor k-ng-model="richTextEditor_665" k-tools="['bold','italic','underline','strikethrough','justifyLeft','justifyCenter','justifyRight','justifyFull','insertUnorderedList','insertOrderedList','indent','outdent']"></textarea>”<br>$('#myTabContent2').html($compile(html)($scope))in previous versions it was working fine.
I have latest version of kendo now Kendo UI v2017.1.223(kendo ui 2017 Q1 sp1).
I got the following errors.

Hello, I have a grid that does not show the caret (up or down) but it does sort asc only. It is firing the sort event when I click the heading of columns with a "field" but it only does a sort descriptor of "asc" and never shows the caret in the grid header? What am I doing wrong?
<kendo-grid [data]="gridView" [height]="400" [sortable]="{mode: 'single'}" [sort]="sort" (sortChange)="sort($event)">
<kendo-grid-column title="#" [width]="30">
<template kendoGridCellTemplate let-rowIndex="rowIndex">{{rowIndex + 1}}</template>
</kendo-grid-column>
<kendo-grid-column title="Edit" [width]="60">
<template kendoGridCellTemplate let-dataItem>
<a class="btn btn-primary" (click)="edit(dataItem.Id)" title="Edit {{dataItem.Id}}">
<i class="fa fa-edit white"></i>
</a>
</template>
</kendo-grid-column>
<kendo-grid-column field="Location" title="Location">
<template kendoGridCellTemplate let-dataItem let-rowIndex="rowIndex">
{{dataItem.Location}} - {{locName[rowIndex]}}
</template>
</kendo-grid-column>
<kendo-grid-column field="Sdate" title="Date and Time Created">
<template kendoGridCellTemplate let-dataItem>
{{dataItem.Sdate | date: 'MM/dd/yyyy'}} - {{'01/01/01 ' + dataItem.Stime | date: 'HH:mm:ss'}}
</template>
</kendo-grid-column>
<kendo-grid-column field="DownCount" title="Count"></kendo-grid-column>
<kendo-grid-column field="ScanBy" title="Scanned By"></kendo-grid-column>
<kendo-grid-column [width]="60" title="Del">
<template kendoGridCellTemplate let-dataItem>
<a class="btn btn-danger" (click)="delete(dataItem.Id)" title="Delete Scan Entry">
<i class="fa fa-close white"></i>
</a>
</template>
</kendo-grid-column>
</kendo-grid>

Hi,
Does the Kendo MVC grid handle HTTP 500 errors that thrown during the CRUD operations? The 'error_handler' is fired but no errors are displayed?
Do I have to catch the exceptions and manually add them to the "ModelState' dictionary for them to be displayed to the user using 'error_handler' javascript funtion? See my html markup below.
@(Html.Kendo().Grid<Province>() .Name("ProvinceGrid") .Columns(columns => { columns.Bound(l => l.Name).Title("Name"); columns.Command(command => { command.Edit(); command.Destroy(); }).Width(200); }) .ToolBar(toolbar => toolbar.Create()) .Editable(editable => editable.Mode(GridEditMode.InLine)) .Pageable() .Scrollable() .HtmlAttributes(new {style = "height:450px;"}) .DataSource(dataSource => dataSource .Ajax() .PageSize(20) .Events(events => events.Error("error_handler")) .Model(model => model.Id(p => p.Id)) .Create(update => update.Action("Create", "Province").Data("getCountryId")) .Read(read => read.Action("Read", "Province", new {countryId = Model})) .Update(update => update.Action("Update", "Province")) .Destroy(update => update.Action("Delete", "Province")) ) )
I appreciate your help.

I am using html.Encode when saving the data in the db. So in the db I have <> but when I show the data in the grid to the users I want them to see <>. How can I accomplish decoding the string?
function loadActivity2Grid() {
intCompanyValue = $('#hdnCompanyID').val();
if (intCompanyValue != "0" && blnActivityLoaded == false) {
var ds = new kendo.data.DataSource({
transport: {
read: {

}
}
}
, sort: ({ field: "appt_date", dir: "desc" })
});
