Questions on UI for ASP.NET MVC Forum

So I have a situation where I am using asp.net MVC controllers in a web interface I'm working on.

The way it's set up is such that the controller passes a model to the view which then has it defined like this: @model ExceptionReportDBModel.Contributor

ExceptionReportDBModel.Contributor is a class generated by EntityFramework.

The issue is, I can't find a way, using mvc wrapper functions, to bind a textbox or textlabel to the model. I have only been able to find solutions using javascript, which presents a problem because I have not been able to figure out how to bind to the model provided by my asp.net mvc controller using javascript...

If someone know of a wrapper function for this, or if you know how to use javascript along with an mvc model passed from the controller, that would be quite helpful.

var chart = $("#SalesChart").data("kendoChart");

chart.dataSource.read({

Pass DataSourceRequest as Parameter in Javascript Ajax Call

I have a page that has a grid and some filter fields (external from the grid). The filtering gets applied to the grid in the JavaScript - which works fine. I also have an export button that I need to export the data in my grid - since my grid does not contain all the data that my export needs, my thought was to pass the DataSourceRequest as a parameter to my Ajax call, select my data and then use the "toDataSourceResult()" as happens in my ajax read controller action. This is not working.

I have the following code in my javascript function that builds my datasource request, and passes it in as a parameter, but my DataSourceRequest object in my controller action contains null values for filter, sort, etc.

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

var parameterMap = grid.dataSource.transport.parameterMap;

var

requestObject = parameterMap({ Sorts: grid.dataSource.sort(), Filters: grid.dataSource.filter(), Groups: grid.dataSource.group()});

How can I pass the datasource request as a parameter to my Ajax Controller action? I have attached a working sample project.

Grid PopupEditor problem when multiple rows are selected

Hello,

I have a grid that contains a check box for each row. A popup editor is displayed when multiple rows are selected. But when a change is made in the popup editor, one of the selected rows loses it's check box selection. My questions are:

1. How do I prevent the a row from being un-selected when a field is modified in the popup editor field?
2. How do I capture an event in the popup-editor window?

Here's is my grid setup:

Html.Kendo().Grid<ResourceInfo>()

.Name("GalleryGrid")

.Columns(columns =>

{

columns

.Bound(r => r.Id).Hidden();

columns

.Bound(r => r.previewUri)

.Width(150)

.Title("Preview")

.Template(@<text><a data-lightbox="@item.uri" href="@item.uri"><img alt="" class="center thumbnail-image" src="@item.previewUri"/></a></text>)

.ClientTemplate("<a data-lightbox='#= uri #' href='#= uri #'><img alt='' class='center thumbnail-image' src='#= previewUri #'/></a>");

columns

.Bound(r => r.colors).Width(100)

.Title("Color");

columns

.Bound(r => r.sizes).Width(100)

.Title("Size");

columns

.Bound(r => r.seasons).Width(100)

.Title("Season");

columns

.Bound(r => r.categories).Width(200)

.Title("Categories");

columns

.Bound(r => r.stockImageKeywords).Width(275)

.Title("Keywords");

columns

.Template(@<text><input type='checkbox' class='check_row'/></text>)

.Width(45)

.Title(" ")

.ClientTemplate("<input type='checkbox' class='check_row' value='#=Id#'/>");

//columns.Command(command => { command.Select().Text("<input type='checkbox' id='editChk'/>"); }).Width(80);

columns.Command(command => { command.Edit().Text(" "); }).Title("Edit").Width(80);

columns.Command(command => { command.Destroy().Text(" "); }).Title("Delete").Width(80);

})

.ToolBar(toolbar =>

{

toolbar.Custom().Text("Add (upload)").Url("#uploadModal").HtmlAttributes(new { @class = "btn", data_toggle = "modal" });

})

.DetailTemplate(@<text>

<div>FileName: @item.fileName</div>

<div>uri: @item.uri</div>

<div>previewUri: @item.previewUri</div>

<div>rating: @item.rating</div>

<div>region: @item.region</div>

</text>)

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

.Sortable()

.Scrollable()

.Filterable()

.Pageable(builder => builder.PageSizes(new[] { 50, 100, 500, 1000 }).Refresh(true))

//.Scrollable( scrollable => scrollable.Virtual( true ) )

.HtmlAttributes(new { style = "height:600px" })

.Resizable(resize => resize.Columns(true))

.Reorderable(reorder => reorder.Columns(true))

.DataSource(dataSource =>

dataSource

.Ajax()

.Batch(false)

.ServerOperation(true)

.Model(model =>

{

model.Id(r => r.Id);

model.Field(r => r.previewUri).Editable(false).DefaultValue(string.Empty);

model.Field(r => r.colors).Editable(true).DefaultValue(string.Empty);

model.Field(r => r.seasons).Editable(true).DefaultValue(string.Empty);

model.Field(r => r.categories).Editable(true).DefaultValue(string.Empty);

model.Field(r => r.stockImageKeywords).Editable(true).DefaultValue(string.Empty);

})

.Events(events => { events.Error("error_handler");events.Change("change_handler"); })

.Read(read => read.Action("read", "gallery")).PageSize(50)

.Update(update => update.Action("update", "gallery").Data("GetSelectedIds").Type(HttpVerbs.Post))

.Destroy(delete => delete.Action("delete", "gallery").Type(HttpVerbs.Post))

)

.ClientDetailTemplateId("client-template")

Add values to MultiSelect from Grid select

Hi,
I have a multiselect that works very well:

@(Html.Kendo().MultiSelectFor(model => model.SurgeryMultiSelect).Filter("contains")

.Name("SurgeryMultiSelect")

.DataTextField("Description")

.DataValueField("ProcedureTypeId")

.Placeholder("Select Procedure(s)...")

.DataSource(source =>

{

source.Read(read =>

{

read.Action("GetAllProcedures", "CommonJsonActions");

});

})

.Events(e =>

{

e.Change("fnSurgeryListChange");

})

)

I also have a grid with a select option that will call a js function; in this function I want to add the selected value from the grid to the select items in the multiselect, if it doesn't already exist. Then call the change event in the multiselect if anything new is added.

Any help will be appreciated.
Thanks,
Shehab

DatePickerFor in grid - validation problem

Hi,

I have EditorTemplate in column in kendoGrid:

columns.Bound(p => p.DatumVznikuKontraktu).EditorTemplateName("Date").ClientTemplate("#= kendo.toString(DatumVznikuKontraktu, 'd') #" +<br>

"<input type='hidden' name='ZamKontrakts[#= index(data)#].DatumVznikuKontraktu' value='#= nullTest(DatumVznikuKontraktu) #' />"

).HeaderHtmlAttributes(new { style = "white-space:pre-wrap; vertical-align:middle" });

EditorTemplate Date:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DateTime?>" %>

<%: Html.Kendo().DatePickerFor(m => m)

.Format(LanguageResources.Resource.DateFormat)

.Culture(System.Threading.Thread.CurrentThread.CurrentCulture.ToString())

%>

Culture is SK-sk (slovakia). DateFormat - dd.MM.yyyy

Can you help me ?

Set WidgetBuilderBase ToHtmlString method as virtual?

Hi I would like to suggest to set the ToHtmlString method in the WidgetBuilderBase class as virtual so it can be used as an extensibility point.
I wanted to add some logic before the call ToHtmlString using dynamic proxies on the builders and at the end it wasn't as straight forward as I would wanted it to be.
I would have been a lot easier if the method was virtual and I think it is a harmless change.

TimePicker popup width formatted wrong

We can't really figure out what is causing this, but all of a sudden, all our TimePickers' popup's got wrong width-formatting (exceptionally small - see picture). Have anyone experienced anything similar or have a proposal to a fix? Is there a way to override this property?

Our code should be straightforward (excepts it is a rather large solution, and everything can change the behavior).
Html:

<td class="col-xs-3">

<input name="startTime" id="startTime" data-val-required="" />

</td>

Js:

_startTime = $("#startTime").kendoTimePicker({

format: "HH:mm",

change: changePeriodTypeOptions

}).data("kendoTimePicker");
