Pass model to template of Grid

Hello,

I have a grid edits in pop up:

.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("RecordViewModelTemplate"))

The fields bind well to the model in the template when I do:

However, the fields don't bind to the model when I try:

@Html.CheckBoxFor(m => m.SampleTestPackage.biochemistry[1].Selected, new Dictionary<string, object> { { "class", "biochemistry" }, { "data-test", "Comprehensive" } })

If the value is true in the model the check box doesn't appear selected.

I have tried also:

<h5> BIOCHEMISTRY </h5>
<div class="row">
@{ for (int i = 0; i < @ViewBag.biochemistry.Count; i++)
{
var biochemistryId = String.Format("biochemistry{0}", @ViewBag.biochemistry[i].Value);
<div class="form-group col-4">
<div class="custom-control custom-checkbox">
@Html.HiddenFor(m => m.SampleIndividualTest.biochemistry[i].Value)
@Html.HiddenFor(m => m.SampleIndividualTest.biochemistry[i].Text)
<input type="checkbox" id=@biochemistryId class="biochemistry custom-control-input" asp-for="@Model.SampleIndividualTest.biochemistry[i].Selected">
<label for=@biochemistryId class="custom-control-label"> @Html.Raw(@ViewBag.biochemistry[i].Text)</label>
</div>
</div> } }
</div>

but the check boxes don't bind and remain false when they are true/selected in the model.

If I do:

@{

if (Model == null){

<span> Model is empty </span>

}

I get as result that the model is empty.

I don't understand why some fields like AnimalId bind to the model and other no - when the model is apparently empty.

I am not coding anything to bind the model the template - is there any code I need to bind the model to the template when the edit event is clicked in the grid?

Also, when the update event is fired, the control gets and empty model, I suppose that it is logic as the model is empty.

Any help is appreciated, I suppose that I am missing the concept.

Kind Regards.

Custom steps in Wizard for ASP.NET Core

Hello,

Could we customize the wizard functionality?

For example:

1) disable the change of the content within the Circle of the Step,

2) use a custom icon/img instead of Check Icon which is currently displayed?

Customize appearance

Is there a way to customize the appearance of the color picker popup window? For example, can I add a text separator, or perhaps a tooltip to each tile in the color picker?

Thanks

Grid popup: How to display validation errors inline (rather than as hint bubble)

In a grid with GridEditMode.Popup, validation errors for fields in the pop-up window appear as a hint bubble by default.

Is it possible to change the style of the validation so that errors in the pop-up window appear below the input fields (as they might for a normal html form)?

See images for example.

Thanks,

Grid

Binding Problem

Hi,

How can I bind a model to grids, combo, textarea etc into my tabStrip and get my model populated back on button press?

This is my Index.cshtml

@model RestRequestModel

<form method="post" asp-action="Index">

<div style="margin-bottom:5px;">

<button id="invokeBtn" class="k-button k-primary" name="invoke" value="Invoke">Invoke</button>

</div>

<div style="margin-bottom:5px;">

<h3>Request</h3>

<select asp-for="Method" style = "width:18%;"

asp-items="@new SelectList(Enum.GetNames(typeof(RestSharp.Method)))"></select>

<input type="text" placeholder="Type URL here ..." style="width:80%; margin-left:10px;" asp-for="Url"

value='@Model?.Url' />

</div>

<div class="k-content">

@(Html.Kendo().TabStrip()

.Name("tabstrip")

.Animation(animation =>

animation.Open(effect =>

effect.Fade(FadeDirection.In)))

.Items(tabstrip =>

{

tabstrip.Add().Text("Url Segments")

.Selected(true)

.Content(@<text>

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

.Name("UrlSegmentsGrid")

.Columns(columns =>

{

columns.Bound(p => p.Name).Title("Key");

columns.Bound(p => p.Value).Title("Value");

columns.Command(command => { command.Edit().Text(" "); command.Destroy().Text(" "); }).Width(172).HtmlAttributes(new { style = "vertical-align:top;" });

})

.ToolBar(toolbar => toolbar.Create().Text("New"))

.Pageable()

.Sortable()

.Editable(editable => editable.Mode(GridEditMode.InLine))

.Scrollable(scr => scr.Height(430))

.Filterable()

.DataSource(dataSource => dataSource

.WebApi()

.PageSize(20)

.Events(events => events.Error("error_handler"))

.Model(model =>

{

model.Id(p => p.Name);

})

//.ServerOperation(false)

//.Read(read => read.Action("GetUrlSegments", "RestClient", Model))

//.Destroy(update => update.Action("UrlSegments_Destroy", "RestClient"))

)

</text>);

tabstrip.Add().Text("Authorizations")

.Content(@<text>

<div style="margin-bottom:5px;">

<h5>Authentication Mode</h5>

@(Html.Kendo().ComboBox()

.Name("authenticationModeCombo")

.HtmlAttributes(new { style = "width:100%;" })

.DataTextField("Text")

.DataValueField("Value")

.DataSource(dataSource =>

dataSource.Read(read => read.Action("GetAuthMode", "RestClient")))

.Events(events => events.Change("authenticationModeChanged"))

.SelectedIndex(0)

)

</div>

<hr />

<div id="httpBasicAuthPanel" style="display:none;">

<table width="100%">

<tr>

<td style="width:20%">Username</td>

<td><input type="text" asp-for="BasicAuthAuthModel.Username" name="usernameTxt" style="width:100%;"/></td>

</tr>

<tr>

<td style="width:20%">Password</td>

<td><input type="password" name="passwordTxt" asp-for="BasicAuthAuthModel.Password" style="width:100%"/></td>

</tr>

</table>

</div>

<div id="Oaauth2Panel" style="display:none;" >

<table width="100%">

<tr>

<td style="width:20%">Authentication endpoint</td>

<td><input type="text" name="authEndpointTxt" asp-for="MSAzureOAUTH2AuthModel.AuthenticationAuthorityUrl" style="width:100%"/></td>

</tr>

<tr>

<td style="width:20%">Client Id</td>

<td><input type="text" name="clientIdTxt" asp-for="MSAzureOAUTH2AuthModel.ClientId" style="width:100%"/></td>

</tr>

<tr>

<td style="width:20%">Client Secret</td>

<td><input type="text" name="clientSecretTxt" asp-for="MSAzureOAUTH2AuthModel.ClientSecret" style="width:100%"/></td>

</tr>

</table>

</div>

</text>);

})

)

</div>

</form>

<script>

$(document).ready(function () {

$("#invokeBtn").kendoButton();

});

//error handler dei grid

function error_handler(e) {

if (e.errors) {

var message = "Errors:\n";

$.each(e.errors, function (key, value) {

if ('errors' in value) {

$.each(value.errors, function () {

message += this + "\n";

});

}

});

alert(message);

}

//Mostro/nascondo i div nel tab Authorizations

function authenticationModeChanged() {

var value = this.value();

if (value == 1) {

document.getElementById("httpBasicAuthPanel")

.style.display = "block";

document.getElementById("Oaauth2Panel")

.style.display = "none";

}

else if (value == 2) {

document.getElementById("httpBasicAuthPanel")

.style.display = "none";

document.getElementById("Oaauth2Panel")

.style.display = "block";

}

</script>

This is my Controller

public IActionResult Index()

{

ViewData["authTypesData"] = GetRequestType();

return View(new RestRequestModel

{

HeaderParameters = new List<RestParameter>(),

UrlSegmentParameters = new List<RestParameter>(),

QueryParameters = new List<RestParameter>(),

BasicAuthAuthModel = new BasicAuthAuthenticationModel(),

MSAzureOAUTH2AuthModel = new MSAzureOAUTH2AuthenticationModel()

});

}

[HttpPost]

public IActionResult Index(RestRequestModel model)

{

var url = model.Url;

etc..

return View();

}

model.Url and Method are populated on postback but anything else is null

Thank you

Multiple TestBoxFor on one page

I have a page bound to model with multiple comboboxes and textboxes which like
@(Html.Kendo().ComboBoxFor(i => i.Accountant)...) and @(Html.Kendo().TextBoxFor(m => m.ZipCode)...) etc.
I also have a textbox bound to "Name" property of the model:
@(Html.Kendo().TextBoxFor(m => m.Name)...)

Also on the same page I have a grid (bound to another data) with popup editable window.
And this popup window also has a textbox bound to "Name" property (but from another model).
This particular textbox looks like simple input, not like kendo ui element.

I think, this is because I have two TextBoxFor elements, each bound to a property "Name" and so they have same id attributes ("#Name").

Is it possible to make textbox in popup window to looki like kendo element without renaming property of the model? Or is it possible to change the id of the second TextBoxFor element?

I tried to add the .Name("AnotherName") method to the second TextBoxFor element, but it doesn't work, the page doesn't load correctly. I tried to add the .Name("AnotherName") method to the first TextBoxFor element, but I received an error "You cannot override component name when bound to a model expression"

What's with the Theme Builder?

Ok, so what is the deal with the Progress/Telerik Theme builder? My hopes was that it would skin the kendo controls so I wouldn't have to mess (much) with the CSS, and to possibly have multiple color versions.

The problem is, it seems there are two, both have issues but the "newer" one seems to have less functionality.

There is this: http://themebuilder.telerik.com (The "newer" builder)

But this "newer" builder just seems to ignore some controls. For example, the Grid's hover feature seems to be ignored, and colorization seems to have no effect on the grid (for example, selecting a row).

I guess more granularized options are out of the question? If I have to add more css AFTER using the theme builder, why am I using the theme builder?

I tried the Bootstrap4 version, but it has weird issues as well. things like headers are out of alignment or just completely malformed. I thought maybe it was because I didn't have Bootstrap4 setup in my project, but that didn't seem to help either!

Then there is this: https://demos.telerik.com/kendo-ui/themebuilder

This one seems to be more complete but has it's issues too. This one seems to work better than the "Progress Sass" version, but I'm worried it is going to disappear because of the "newer", "better" Progress Theme Builder.

Can someone explain/clarify?

Thanks!

UIHint ignored on form items

I have properties decorated with the UIHint attribute on my view models. When binding one of these properties to a Form control's items, it ignores the UIHint (and the type completely in some cases). Can you only set a Form's item control type via the Editor method? Or can the Form control infer the control type via UIHint somehow?

Form
