Nested Kendo Grid (details) into Kendo Window

I saw demo about custom command, where it shows details into a Telerik Windows (modal).

We suppose thatwe have product list, and we want obtain ledger entries relative.

I met a problem to pass the Product ID to grid that I want to use for filter ledger entries.

I try to insert a TAG Helper into kendo template

<script type="text/x-kendo-template" id="template">

<div id="details-container">

<div>

<h2>#= description #</h2>

<em>#= ID #</em>

</div>

@(Html.Kendo().Grid<ItemLedgerEntryModel>() .Name("ileGrid") .Filterable() .AutoBind(true) .Columns(columns => { columns.Bound(f => f.DocumentNo); columns.Bound(f => f.OrderNo); columns.Bound(f => f.VendorNo); columns.Bound(f => f.PostingDate).Format("{0:dd/MM/yyyy}"); columns.Bound(f => f.EntryType); columns.Bound(f => f.UnitOfMeasureCode); columns.Bound(f => f.Quantity).Format("{0:N2}").HtmlAttributes(new { style = "text-align: right;" }); }) .Sortable() // Enable sorting .Pageable() .Scrollable(scrollable => scrollable.Virtual(true)) .DataSource(dataSource => dataSource //Configure the Grid data source. .Ajax() //Specify that Ajax binding is used. .Read(read => read.Action("LedgerEntries", "ItemLedgerEntry").Data(new {itemNo: #= ID #})) //How can I do this???? ) )

</div>

</script>

but it not "receives" Produc ID.

Where I wrong?

Enable Custom Command by data

I would like to enable or disable the custom command based on the current line value.

My model, called ItemModel has a property called HasPicture, custom command called "GetPictureCommand" should be disabled when HasPicture returns false.

@(Html.Kendo().Grid<ItemModel>

()

.Name("itemGrid")

//.ToolBar(t => t.Search())

.Filterable()

.AutoBind(true)

.Columns(columns =>

{

columns.Bound(f => f.No);

columns.Bound(f => f.Description);

columns.Bound(f => f.Brand);

columns.Command(c => c.Custom("GetPictureCommand").Text(" ").IconClass("k-icon k-i-image").Click("getImage")).Width(52);

columns.Bound(f => f.PurchasesQty).Format("{0:N2}").HtmlAttributes(new { style = "text-align: right;" });

columns.Command(command => command.Custom("ItemLedgerEntryPurchaseCommand").Text(" ").IconClass("k-icon k-i-arrow-drill").Click("showPurchaseDetails")).Width(52);

columns.Bound(f => f.NetChange).Format("{0:N2}").HtmlAttributes(new { style = "text-align: right;" });

columns.Command(command => command.Custom("ItemLedgerEntryCommand").Text(" ").IconClass("k-icon k-i-arrow-drill").Click("showDetails")).Width(52);

columns.Bound(f => f.LastEntryDate).Format("{0:dd/MM/yyyy}");

})

.Pageable() // Enable paging

.Sortable() // Enable sorting

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

.HtmlAttributes(new { style = "height:430px;" })

.DataSource(dataSource => dataSource //Configure the Grid data source.

.Ajax() //Specify that Ajax binding is used.

.PageSize(10)

.Read(read => read.Action("Item_ReadData", "Home").Data("additionalData"))

)

How can I do this?

How to using Windows.LoadContentFrom with parameters

Hi to all,

I would create a colum custom to open a window that contains details (related table about relative row).

I red Loading External Form and I'm thinking to use this approach.

But I would pass a key of my row, so that I could retrieve details rows and show in a modal window.

@(Html.Kendo().Window()

.Name("ItemLedgerEntries")

.Title("Movimenti")

.LoadContentFrom("GetItemLedgerEntries", "Home").Additional("#= ItemNo #") //is my hope......

.Iframe(true)

.Resizable()

.Draggable()

.Modal(true)

)

How can I pass a key to window?

Style Menu

I need to style the menu and I'm horrible at css. I have made a .css file from the Template/Style builder. That was a great experience and is an awesome tool. But, I'm looking for help doing the following on one menu (don't want it to be the global style):

Horizontal Alignment-Right: Align all the Menu.Items to the right.
Reduce the Margin around everything in order to size the menu smaller.
Reduce the Font Size
Change the Font Color (Black with bright background, White with dark background)
Change the background color of the entire menu control to a solid color then a gradient. (I'll try both)
Instead of having a sharp edge on the bottom left of the menu, make it a radius.
Limit the width of the menu to 1/2 the width of the page.

Thanks in advance for your help,

Joel

My Menu:

@(Html.Kendo().Menu()

.Name("menu")

.Items(items =>

{

items.Add().Text(Glossary.Models.Group.Plural)

.ImageUrl(Url.Content("~/images/32/group.png"))

.Action("Index", "Groups", routeKeys);

items.Add().Text(Glossary.Models.User.Plural)

.ImageUrl(Url.Content("~/images/32/People.png"))

.Action("Index", "Users", routeKeys);

items.Add().Text(Glossary.Models.Patient.Plural)

.ImageUrl(Url.Content("~/images/32/patient.png"))

.Action("Index", "Patients", routeKeys);

items.Add().Text(Glossary.Models.Session.Plural)

.ImageUrl(Url.Content("~/images/32/session.png"))

.Action("Index", "Sessions", routeKeys);

}

)

Get/Set selected row woes

This should be easy, but appears not.

I have a grid with a custom command:

columns.Command(c => c.Custom("Run Report").Click("OnRunReport")).Width(140);

selectable is set as

.Selectable(s => s.Mode(GridSelectionMode.Single).Type(GridSelectionType.Row))

My OnRunReport needs to get the selected row index and set it as the selected row. This needs to happen before I call:

// this next line only works if .Selectable() is set.

var idx = $("#grid").data("kendoGrid").select().index()

because otherwise idx is -1. If I click on the desired row before clicking on the Run Report button, idx is correctly set.

How to force the selection of the row in the click event of the custom command (In my case OnRunReport)???

The ultimate goal it to get the value of a particular cell for the selected row to be able to pass it to a report.

Any help would be great!

Thanks ... Ed

function OnRunReport(arg)

{

// this next line only works if .Selectable() is set.

var idx = $("#grid").data("kendoGrid").select().index();

var certid = this.dataSource._data[idx].id;

window.location.replace = "/CertificateReport/" + certid;

}

@(Html.Kendo().Grid<IndexModel.CertificateModel>()

Ensure selected node is visible

I know understand how to set a node in the TreeList as selected on databound. However, if this tree data is long how do I get the control to scroll to the selected node?

My Tree:

<script id="icon-template" type="text/x-kendo-template">

<div class='group-icon'

style='background-image: url(@Url.Content("#: ImageUrl #"));'></div>

<div class='group-name'>#: Name #</div>

</script>

@(Html.Kendo().TreeList<Group>()

.Name("treelist")

.Columns(columns =>

{

columns.Add().Field(e => e.Name).TemplateId("icon-template").Width(225);

})

.HtmlAttributes(new { style = "height:550px;" })

.Selectable(s => s.Mode(TreeListSelectionMode.Single))

.DataSource(dataSource => dataSource

.ServerOperation(false)

.Read(read => read.Action("IndexJson", "Groups").Data("treeGetData"))

.Model(m =>

{

m.Id(f => f.Id);

m.ParentId(f => f.ParentId);

m.Expanded(true);

m.Field(f => f.Name);

})

.Sort(s => s.Add(f => f.Name)))

.Events(events =>

{

events.DataBound("onDataBound");

})

)

JavaScript:

// show the matching groupId as selected in the treelist

function onDataBound(e) {

// Handle the dataBound event.

var treelist = e.sender;

//alert(treelist == null);

var initiallySelectedID = $("#groupId").val();

alert(initiallySelectedID);

var dataItem = treelist.dataSource.get(initiallySelectedID);

//alert(dataItem == null);

var row = $("tr[data-uid='" + dataItem.uid + "']");

treelist.select(row);

}

Difference between CDN resources and NPM resources

I'm trying to add the Kendo UI (v2020.1.406) to my ASP.net Core project through NPM and copy it with Webpack to the lib folder.

Now the problem I'm hitting is the following, If I add the CDN resources to my project, everything works like a charm,... but when I'm adding the same resources with the same version that I installed via NPM to the project, I'm confronted with a wall of error's in the console of my browser. Now I'm not completely sure what is happening, but you can see what happens in the project below

Github Repo KendoNPMResources.

A nudge in the right direction would be awesome !

Treelist always empty

Hi,

I created a project and i need to put a treelist view to handle parents and child elements of a grid. I created a father and a child, but the page doesn't load any record in my grid. Am i missing something?

The attached files are the grid viewed in my page and the model received from the datasource

Here is the model

public class ProjectTaskViewModel

{

public string IdTask { get; set; }

public string FatherId { get; set; }

public string TaskTitle { get; set; }

}

The View:

@(Html.Kendo().TreeList<Models.ProjectTaskViewModel>()

.Name("treelist")

.Columns(columns =>

{

columns.Add().Field(p => p.IdTask).Title(" ").Filterable(false).Sortable(false).Width("105px").Template("#=customformatter(Id)#");

columns.Add().Field(p => p.TaskTitle).Title("Nsme");

})

.Pageable(p => p.Refresh(true).PageSize(20).PageSizes(new int[] { 20, 50, 100 }))

.Sortable()

.Filterable()

.DataSource(dataSource => dataSource

.Read(read => read.Action("TreeViewDataSource", "ProjectTask").Data("CustomData")) //Function that contains correctly the IdProject param

.ServerOperation(false)

.Model(m => {

m.Id<string>(p => p.IdTask);

m.ParentId<string>(p => p.FatherId);

m.Field(p => p.TaskTitle);

m.Field<string>(p => p.FatherId);

})

)

And finally the TreeViewDataSource:

public JsonResult TreeViewDataSource([DataSourceRequest]DataSourceRequest request, string IdProject)

{

var temp = _db.ProjectTasks.Where(o => o.IdProject == IdProject).Select(o => new ProjectTaskViewModel

{

FatherId = o.ParentId,

IdTask = o.Id,

TaskTitle = o.Title

});

var result = temp.ToTreeDataSourceResult(request, o => o.IdTask, o => o.FatherId, o => o);

return Json(result);

}

TreeList
