We Keep Coding

In Kendo Master Detail Grid (jquery) is there a way to update a field in the parent row if no child records exist?

I have a Kendo Master/Detail grid (jquery) that expands all rows to reveal any child records upon page load to provide a grid with a set of default data. However, not all of the rows returned when expanded have child elements to display. I currently have a link provided in a column of the master row, the link is coded using a template:
{
template: `"<a class='_kwJISSearch' style='color:blue; text-decoration:underline; cursor: pointer;'>Edit Case Assignment</a>",`
width: "100px"
}
What I would like to know if I can change the text and what the link is pointing to on the master row if no child elements are returned? I have provided my code below, where I create the columns for the master first, then create the grid with a data-bound, lastly, I coded the detail:
function loadSearchGrid() {
searchOriginalColumnList = [
{
field: "CaseYear",
title: "Case Year",
type: "number",
width: "100px"
},
{
field: "CaseNumber",
title: "Case Number",
width: "100px"
},
{
field: "Full_Style",
title: "Style",
template: "<a href='/Cases/Views/CaseItems/ViewDocket?cy=#=CaseYear#&cn=#=CaseNumber#' target='_blank' style='color: blue; text-decoration:underline' ># if(Full_Style == null || Full_Style == '' ) {# N/A #} else{ # #:Full_Style# #} # </a>",
width: "250px"
},
{
field: "DispInfo",
title: "Disp Info",
width: "175px"
},
{
field: "Max_OA",
title: "OA Date",
format: "{0:MM/dd/yyyy}",
width: "100px"

You can use JavaScript code inside a template, e.g.:
template: "<a class='_kwJISSearch' style='color:blue; text-decoration:underline; cursor: pointer;'># if (data.childrenProperty && data.childrenProperty.length) { ##Edit Case Assignment## } else { ##No children text here ## } #</a>",
Assuming your master row has an array property for children.

Telerik Kendo grid get row details from template

I am using kendo grid with MVC in a .NET project. Two columns of my grid are templates and those have an input text inside of the template. That way every time the grid loads the input texts are always visible and available for change.
When the user clicks on save, I need to check all the rows of the grid, at client side and get the values of those two columns (the only two have templates) and get the values of the input box. So the result I am expecting is a list with two columns that have the last values inserted by the user in the input boxes and not the original value.
Here is my code:
//Grid Data source
var dataSource = new kendo.data.DataSource({
transport: {
read: { url: "/CsmForecastRegistration/GetForecast", cache: false }
},
error: function (e) {
openDialog(e.errorThrown);
},
batch: true,
pageSize: 20,
schema: {
data: "Data",
total: "Total",
errors: "Errors",
model: {
id: "ForecastItemId",
fields: {
ForecastItemId: { editable: false },
RecordId: { editable: false },
SaleId: { editable: false },
IsUpSell: { editable: false },
BusinessName: { editable: false },
HealthScore: { editable: false },
CurrencySymbol: { editable: false },
ForecastWeekTotalContractValue: { editable: true },
ForecastWeekMonths: { editable: true },
ForecastWeek12Months: { editable: false }
}
}
}
});
$("#grdCsmForecast").kendoGrid({
dataSource: dataSource,
scrollable: true,
dataBound: onDataBound,
toolbar: ["excel"],
excel: {
allPages: true,
fileName: "CSMForecast.xlsx"
},
pageable: true,
columns: [
{ title: "", width: "80px", template: $("#comments-template").html(), attributes: { style: "text-align:center; background-color: white;" } },
{
title: "Contract Details",
columns: [
{ field: "RecordId", title: "RecordId", width: "90px", attributes: { "class": "contractDetailGridStyle" } },
{ field: "SaleId", title: "SaleId", width: "90px", attributes: { "class": "contractDetailGridStyle" } },
{ field: "IsUpSell", title: "Upsell?", width: "75px", attributes: { "class": "contractDetailGridStyle" } },
{ field: "BusinessName", title: "Business Name", width: "250px", attributes: { "class": "contractDetailGridStyle"} },
{ field: "HealthScore", title: "Health Score", width: "95px", attributes: { "class": "contractDetailGridStyle"} },
{ field: "CurrencySymbol", title: "CCY", width: "50px", attributes: { "class": "contractDetailGridStyle" } }
]
},
{
title: "Forecast Week",
columns: [
{ field: "ForecastWeekTotalContractValue", title: "TCV", width: "75px", template: $("#forecast-week-tcv").html(), attributes: { "class": "forecastWeekGridStyle" }, footerTemplate: "#: sum # " },
{ field: "ForecastWeekMonths", title: "Months", width: "70px", template: $("#forecast-weekMonths").html(), attributes: { "class": "forecastWeekGridStyle" } },
{ field: "ForecastWeek12Months", title: "12Month", width: "75px", attributes: { "class": "forecastWeekGridStyle" }, footerTemplate: "#: sum # " }
]
}
]
});
And the templates:
<script id="forecast-week-tcv" type="text/x-kendo-template">
# if(IsNewContract === true ){ #
<span>#=ForecastWeekTotalContractValue#</span>
#}
else{#
<input type="text" value="#=ForecastWeekTotalContractValue#" />
#}#
</script>
<script id="forecast-weekMonths" type="text/x-kendo-template">
# if(IsNewContract === true ){ #
<span>#=ForecastWeekMonths#</span>
#}
else{#
<input type="text" value="#=ForecastWeekMonths#" />
#}#
</script>
So I would like to have a list and send to my MVC the controller all the values of these two inputs:
<input type="text" value="#=ForecastWeekTotalContractValue#" />
<input type="text" value="#=ForecastWeekMonths#" />
Thanks

Try something like this:
function getInputValues() {
let result = [];
$('#grid tbody tr').each((i, tr) => {
let row = {};
$(tr).find('input[type="text"]').each((index, input) => {
row[(index ? "ForecastWeekTotalContractValue" : "ForecastWeekMonths")] = $(input).val();
});
result.push(row);
});
return result;
}
Demo
It just iterates over the elements and adds to an array of objects.

How to set Kendo editor as cell template?

Requirement 1:
I need the user to the ability to edit content of the grid all the time, meaning as a template, the user should not be required click on the field and then the editor appears.
Requirement 2: I want a kendo editor for the user to enter/edit values.
The following is what I tried, since I don't know how to do this using template I tried out using editor
Grid setup:
dataSource: {
data: $scope.planOverviewModel,
sort: {
field: "TermName",
dir: "asc"
},
schema: {
model: {
fields: {
TermName: { type: "string", editable: false },
InNetwork: { type: "string", editable: true },
OutNetwork: { type: "string", editable: true }
}
}
},
},
columns: [
{ field: "TermName", title: "Term" },
{
field: "InNetwork",
title: "In-Network",
editor: $scope.setupTextBox
},
{
field: "OutNetwork",
title: "Out-Network",
editor: $scope.setupTextBox
}
],
editable: true,
change: function (e) {
console.log("changed");
if (e.action == "itemchange") {
this.sync();
}
}
Editor setup:
$scope.setupTextBox = function(container, options) {
$('<textarea class="form-control" type="text" data-bind="value:' + options.field + '"> </textarea>')
.appendTo(container).kendoEditor({
resizable: {
content: true,
toolbar: true
}
});
};

Set a Placeholder if the Value is null in KendoUI

The following Kendo grid with a dropdown. The dropdown AccountCode item is in form of an object as below;
The following is used to display the details;
function loadGrid() {
$("#grdItems").kendoGrid({
dataSource: itemDS,
pageable: {
refresh: false,
pageSizes: false
},
aggregate: [{ field: "Amount", aggregate: "sum" }],
columns: [ {
field: "CostCenter",
title: "Cost Center",
editor: costCenterDropDownEditor,
template: "#:CostCenter.Description#"
}, {
field: "AccountCode",
title: "Account Code",
editor: accountDropDownEditor,
template: "#AccountCode.AccountDescription#"
}, {
field: "Description",
}, {
field: "BillNumber",
title: "Bill Number",
},
{
field: "Amount",
format: "{0:n}",
footerTemplate: "Sum: #= kendo.toString(sum, 'n')#"
},
{ command: [{ name: "edit", text: "MODIFY" }], title: " ", width: "120px" }],
editable: "popup"
});
}
and it looks like this when displayed;
How can I insert a placeholder when the dropdown object is empty as shown in the first image? Tried the usual placeholder tag, but it doesn't seem to work.
EDIT: Code added

I'm pretty sure those strings are just javascript code.
"#:CostCenter.Description.length > 0 ? CostCenter.Description : 'placeholder'#"

How to get checked rows from kendo grid?

I'm trying to use checkbox with every row & then get those row's values, which are checked. this checkbox column is not representing any field in datasource. Here is my Grid:
var SeparatedEmployeeList = $("#SeparatedEmployeeList").kendoGrid({
dataSource: DataSourceSeparatedEmployeeList,
pageable: true,
editable: true,
selectable: "row",
navigatable: true,
filterable: true,
sortable: true,
groupable: true,
height: '200PX',
scrollable: true,
columns: [
{ field: "SLNO", title: "SL.", filterable: false, sortable: false, width: "30px" },
{ field: "EMP_CODE", title: "Code", filterable: false, width: "70px" },
{ field: "EMP_NAME", title: "Name", filterable: true, width: "100px" },
{ field: "DIVI_NAME", title: "Division", width: "70px" },
{ field: "EMP_DESIG_NAME", title: "Designation", width: "75px" },
{ field: "JOINING_DATE", title: "Join Date", width: "60px" },
{ field: "TRMN_TYPE", title: "Separation Type", width: "85px" },
{ field: "TRMN_EFCT_DATE", title: "Effect Date", width: "60px" },
{ field: "LAST_SAL_PROS_MON", title: "Last Salary Proc. Month", width: "110px" },
{ field: "TRMN_REM", title: "Remarks", width: "60px" },
{ field: "Date", title: "Date", width: "65px" },
{ field: "check_row", title: "Submit", width: 60, onClick: test, template: "<input class='check_row' OnCheckedChanged='test' type='checkbox' />" }
]
});
I need to fire a while checking the checkbox to validate user entered data in the date field defined just before the checkbox, & later I will need to iterate through the checked rows to use their values. Please help.

I would change the last item to:
{ title: "Submit", width: 60, template: "<input class='check_row nsa-checkbox' type='checkbox' />" }
Now, using jQuery delegation I would NSA-like capture all the "change" events on every control under the DIV grid, having the css class "nsa-checkbox":
$('#SeparatedEmployeeList').on('change', '.nsa-checkbox', function(e){
// "this" is your checkbox
var myCheckbox = $(this);
// To get the item, you must access the data-uid attribute in the row that wraps the checkbox.
var myDataItem = DataSourceSeparatedEmployeeList.getByUid(myCheckbox.closest('tr').attr('data-uid'));
// Have fun
})

If you later want to iterate through the checked rows in controller you can use
postUrl = '#Url.Content("~/Billing/CustomerAccountManage/AccountsManagerTransferResponsiblityAction")';
paramValue = JSON.stringify(
{
'pEmpID1': gEmpID1
, 'pEmpID2': gEmpID2
, ManagerList: gridData // passing the grid value in controller as parameter
});
$.ajax({
url: postUrl,
type: 'POST',
dataType: 'json',
data: paramValue,
contentType: 'application/json; charset=utf-8',
success: function (result) {
console.log(result);
},
error: function (objAjaxRequest, strError) {
var respText = objAjaxRequest.responseText;
console.log(respText);
}
});
