Questions on UI for ASP.NET Core Forum

Hello,

I'm using Grid Batch Editing (http://demos.telerik.com/aspnet-core/grid/editing) and I have 2 questions actually:

1) Is it somehow possible to allow dropdown buttons when editing records?

2) I have a nullable bool field and when I set it to "Not Set" (null), it will store the value as "false". Is this normal behaviour?

Thanks!

Binding KendGrid data using Angularjs Service/WebAPI

Hi, I'm trying to bind the KendoGrid data source from Angularjs Service which is calling my WebAPI (.NetCore). I'm getting the data in JSON back from webApi and also it is getting populated correctly in my controller variable. However, kendo grid is not showing the data populated. If I use the same JSON output and hard code location variable with that data and bind it to kendo grid it shows the data.

Please help.

JSON from web API:

{"data":{"UsPk":"00000000-0000-0000-0000-000000000000","UsLastname":"Test","StatusCode":0,"Message":"Test"}

Angular Service:

///Get Users from the service
function getUserList() {
return $http.get('http://localhost:88/api/user/gettestuser/1')
.then(getUserListComplete)
.catch(getUserListFailed);

function getUserListComplete(response) {
console.log(response.data);
return response;
}

function getUserListFailed(error) {
logger.error(error.data);
return error.data;
}
};

Angular Controller code:

var grid = $("#grid").kendoGrid({
dataSource: {
data: vm.boardData,
dataType: "json"
},
editable: true,
height: 160,
columns: [
{ field: "usPk", title: "ID" },
{ field: "usLastname", title: "Last Name" }
]
}).data("kendoGrid");

function getUserList() {
return dataService.getUserList()
.then(function (response) {
angular.copy(response.data, vm.boardData);

})

.catch(function (showError) {
alert(showError);
vm.errorMessage = showError;
})
.finally(function () { vm.isBusy = false });
}

//Tried polpulating JSON object and assign it to grid below way as well
//for (var i = 0; i <= vm.boardData.length - 1; i++) {

//var person = {};
//person = {
// usPk: vm.boardData.data.usPk,
// usLastname: vm.boardData.data.usLastname,
//};
vm.grdDataSource = person;
//}

//vm.grdDataSource = JSON.stringify(vm.boardData.data, null, 4);

Issue Batch Grid Editing

Im using in grid batch editing and I noticed that it was not possible to change a bool? to "not set" (null).

When I select from the dropdown "Not set", it will change automatically to "false" when I navigate out of the field.

Thanks

CheckBoxFor EditorTemplate in Grid

I have a checkbox in a grid:

columns.Bound(p => p.Display);

I also have the following editor template:

@model Boolean

@Html.Kendo().CheckBoxFor(m => m)

During editing the checkbox editor template does show, however the checked state is always false even when the underlying data is true.

Different editors in one column (grid.columns[1].editor) not working as expected

Hello,

I use the following approach to configure custom editing UI for the column: http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#configuration-columns.editor
(see also Code below)

this works for textcolumns but there is a Problem with kendoNumericTextBox, kendoTimePicker and kendoDatePicker.
If I click into the column the corresponding editor displays but after editing the wrong value is given back to the text field - for me it looks like there is a formatting problem with the german language...

in this Video https://www.screencast.com/t/GkXn5uS7SH2 you can see what's going on:

changing a time value of 12:33.00 results in "Thu Sep 28 2017 02:00:00 GMT+0200 (Mitteleuropäische Sommerzeit)"
changing a date value of 10.10.1999 results in "Wed Aug 19 1998 00:00:00 GMT+0200 (Mitteleuropäische Sommerzeit)"
in float/decimal value the decimal seperator is in german a comma not a dot - if I type 124,25 the result is 12425.00

How to set the Editors (kendoNumericTextBox, kendoTimePicker and kendoDatePicker) that they give the correct value back?

$(function () {

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

grid.columns[1].editor = function (container, options) {

//-----------------------------------------

//Eintrag_INT

//-----------------------------------------

if (options.model.Profilfeldtyp_ID == 1) {

$("<input name='" + options.field + "' data-bind='value:" + options.field + "'/>").appendTo(container).kendoNumericTextBox({

});

}

//-----------------------------------------

else if (options.model.Profilfeldtyp_ID == 2) {

});

}

//-----------------------------------------

else if (options.model.Profilfeldtyp_ID == 3) {

//$("<input type='checkbox' data-bind='value:" + options.field + "' class='k-checkbox'/>").appendTo(container);

dataTextField: "text",

dataValueField: "value",

dataSource: [

{ text: "JA", value: "JA" },

{ text: "NEIN", value: "NEIN" },

],

});

}

//-----------------------------------------

//Eintrag_VARCHAR

$("<textarea data-bind='value:" + options.field + "' class='k-textbox'/>").appendTo(container);

}

//-----------------------------------------

//Eintrag_MONEY

//-----------------------------------------

else if (options.model.Profilfeldtyp_ID == 5) {

$("<input data-bind='value:" + options.field + "'/>").appendTo(container).kendoNumericTextBox({

format: "c",

decimals: 2,

culture: "de-DE"

});

}

//-----------------------------------------

//Eintrag_TIME

//-----------------------------------------

else if (options.model.Profilfeldtyp_ID == 6) {

$("<input data-bind='value:" + options.field + "'/>").appendTo(container).kendoTimePicker({

dateInput: true,

format: "HH:mm:ss",

parseFormats: ["HH:mm:ss"],

culture: "de-DE"

});

}

//-----------------------------------------

//Eintrag_DATETIME

//-----------------------------------------

else if (options.model.Profilfeldtyp_ID == 7) {

$("<input data-bind='value:" + options.field + "'/>").appendTo(container).kendoDatePicker({

dateInput: true,

format: "dd.MM.yyyy",

culture: "de-DE"

});

}

//-----------------------------------------

//Eintrag_IMAGE

//-----------------------------------------

else if (options.model.Profilfeldtyp_ID == 8) {

$("<input name='files' id='files' type='file'/>").appendTo(container).kendoUpload({

async: {

saveUrl: "save",

autoUpload: true

}

});

}

Reload tab content in partial view...

Hello,

If I reload the tabstrip Content of the second tab with JavaScript with tabStrip.reload(item) in a partialview the Content is not replaced but
always appended...

@(Html.Kendo().TabStrip().Name("tabMitglieddokumenteEdit")

.Animation(false).Items(tab =>

{

tab.Add().Text("Ansicht").Selected(true).Content(@<text><iframe style="position: absolute; height: calc(100% - 70px); width:100%; border: none" frameborder="0" src=

"@ViewBag.BCPHostUrl/DocumentViewer?source=Mitglieddokumente&id=@Model.Mitglied_ID&docid=@Model.Dokument_ID&w=100&h=100&sidepane=true&toolbar=true"

></iframe></text>);

tab.Add().Text("Dokumentdaten").LoadContentFrom("DokumentEdit_Read", "Mitglieddokumente", new { mitgliedid = @Model.Mitglied_ID, dokumentid = @Model.Dokument_ID });

}))

maybe the reason is that the tabstrip is in a partial view but how to avoid that?
