Hi,
we use some grids where we have defined the filters that appear on the columns with:
.Filterable(ftb => ftb.Mode(GridFilterMode.Row)
.Extra(true)
.Operators(operators => operators
.ForString(str => str.Clear()
.Contains(String.Format(SharedLocalizer["lblGridFilterContains"].Value))
.StartsWith(String.Format(SharedLocalizer["lblGridFilterBeginsWith"].Value))
.IsEqualTo(String.Format(SharedLocalizer["lblGridFilterIsEqual"].Value)))
.ForNumber(num => num.Clear()
.IsEqualTo(String.Format(SharedLocalizer["lblGridFilterIsEqual"].Value))
.IsGreaterThan(String.Format(SharedLocalizer["lblGridFilterGreaterThan"].Value))
.IsLessThan(String.Format(SharedLocalizer["lblGridFilterLessThan"].Value))
)
.ForDate(date => date.Clear()
.IsEqualTo(String.Format(SharedLocalizer["lblGridFilterIsEqual"].Value))
.IsGreaterThan(String.Format(SharedLocalizer["lblGridFilterGreaterThan"].Value))
.IsLessThan(String.Format(SharedLocalizer["lblGridFilterLessThan"].Value))
)
)
)
And it works great.
The problem is that when there are grouped columns it works in the "normal" columns but not in the grouped ones (it shows all the filters and not the ones we've defined).
The only way we have found to make it work in every column is to define again in the column that's grouped the filterable operator:
c.Group(group => group
.Title(@SharedLocalizer["lblPaymentdiscountday2"].Value)
.HeaderHtmlAttributes(new { groupname = "paymentsGrid_grp_skonto2" })
.Columns(skonto2 =>
{
skonto2.Bound(m => m.discountday_2).HtmlAttributes(new { style = "text-align: right;" }).Width(90)
.Filterable(f => f
.Cell(cell => cell.Enabled(true).MinLength(100))
.Operators(op => op
.ForNumber(num => num.Clear()
.IsEqualTo(String.Format(SharedLocalizer["lblGridFilterIsEqual"].Value))
.IsGreaterThan(String.Format(SharedLocalizer["lblGridFilterGreaterThan"].Value))
.IsLessThan(String.Format(SharedLocalizer["lblGridFilterLessThan"].Value))
))
);
skonto2.Bound(m => m.discount_2).HtmlAttributes(new { style = "text-align: right;" }).Format(@SharedLocalizer["gridColumnFormatDec"].Value).Width(100).Filterable(f => f.Cell(cell => cell.Enabled(true).MinLength(100)));
skonto2.Bound(m => m.netday).HtmlAttributes(new { style = "text-align: right;" }).Width(90).Filterable(f => f.Cell(cell => cell.Enabled(true).MinLength(100)));
})
);
We'd like to know if there's another way to make the custom filters work in grouped columns, because we'd like to avoid writing the same code for every grouped column in the grid.
Thank you in advance.
Kind regards

I am new to ASP.Core. How do I get the selected items from the "selected" ListBox on the OnPost event?
@(Html.Kendo().ListBox() .Name("optional") .Toolbar(toolbar => { toolbar.Position(ListBoxToolbarPosition.Right); toolbar.Tools(tools => tools .MoveUp() .MoveDown() .TransferTo() .TransferFrom() .TransferAllTo() .TransferAllFrom() .Remove() ); }) .ConnectWith("selected") .DataTextField("PlayerId") .DataTextField("Name") .Draggable(true) .DataSource(ds => ds.Ajax() .Read(r => r.Url("/League/PreDraftPage?handler=Read").Data("forgeryToken"))) ) @(Html.Kendo().ListBox() .Name("selected") .Toolbar(toolbar => { toolbar.Position(ListBoxToolbarPosition.Right); toolbar.Tools(tools => tools .MoveUp() .MoveDown() ); }) .DataTextField("PlayerId") .DataTextField("Name") .BindTo(Model.LeaguePreDraftList) .Selectable(ListBoxSelectable.Multiple)
public void OnPost() { Guid leagueId; List<LeaguePreDraftViewModel> listModel; if (ModelState.IsValid)//save the data { var name = Request.Form["selected"]; listModel = LeaguePreDraftList; } //leagueId = new Guid(id); //get data from page } )

I have a model which looks like this
public class NotificationModel { public List<TableNotificationModel> TableNotificationModel { get; set; } public List<WrongTableNotificationModel> WrongTableNotificationModel { get; set; } }
and I have a view with two different Kendo grids. I want to populate the first Kendo grid with the TableNotificationModel and the second grid with the WrongTableNotificationModel.

@(Html.Kendo().Grid(Model.TableNotificationModel) .Name("successfullData")@(Html.Kendo().Grid<Model.WrongTableNotificationModel>() .Name("unSuccessfullData")
Is there a way to do this? Can I show both table with different models in the same view?

Hey,
I am trying to choose a different template for a popup editor depending on whether a new entry is inserted or an already existing one is modified. I am aware that I probably have to subscribe to the "beforeEdit" event of the grid and act depending on whether e.model.isNew() returns true or false.
However, I was not able to set a different template based on this decision yet. Could you please outline what the cleanest way for doing this would be?
So far my code looks similar to this:
@(Html.Kendo().Grid<Data.Promotion>() .Name("promotionGrid") .Columns(c => { ... c.Command(cmd => cmd.Edit()).Width(120); c.Command(cmd => cmd.Destroy()).Width(120); }) .Events(e => { e.BeforeEdit("beforeEdit"); e.Edit("edit"); }) .DataSource(c => { c.Ajax() .Read(o => o.Url("CodeManagement?handler=Read").Data("forgeryToken")) ... .Model(m => { m.Id("PromotionId"); ... }); }) .ToolBar(c => { c.Create(); }) .Editable(c => { c.Mode(GridEditMode.PopUp); c.TemplateName("Promotion"); // using a static template right now, we want to change that
}))
Moreover, in the Edit-template, I have to constrain a DatePicker based on some model properties. However, the Model field is not set which leads to a NullReferenceException. Is there any way to set the Model field of the template to the entry that is currently being edited/created?
Thank you.

I have a grid with a details panel.
The details panel has the following template:
<script id="SuggestionGridDetailsTemplate" type="text/kendo-tmpl"> @(Html.Kendo().Splitter() .Name("sug-splitter-#=SuggestionID#") .HtmlAttributes(new { style = "height: 500px;" }) .Orientation(SplitterOrientation.Vertical) .Panes(verticalPanes => { verticalPanes.Add() .HtmlAttributes(new { id = "sug-top-#=SuggestionID#" }) .Collapsible(false) .Size("#if(Status == 0){#54px#}else{#100px#}#") .Content(@<div class="container"> <div class="row"> #if(Status == 0){# <div class="col-2 offset-10 float-right"> @(Html.Kendo().Button() .Name("DeleteSuggestionBtn-#=SuggestionID#") .HtmlAttributes(new { type = "button", @class = "k-btn-danger mt-2 float-right" }) .Events(e => e.Click("DeleteSuggestionBtnClick")) .Content("Delete").ToClientTemplate()) </div> #} else {# <div class="col-4"> <label>Actioned by:</label> <p>#=ActionedBy#</p> </div> <div class="col-8"> <label>Comments:</label> <p>#=Comments#</p> </div> #}# </div> </div>); verticalPanes.Add() .HtmlAttributes(new { id = "sug-bottom-#=SuggestionID#", @class="iv-pane-no-overflow" }) .Resizable(false) .Collapsible(false); }).ToClientTemplate())</script>
The grid has a DetailExpand event that will populate the bottom pane of the "sug-splitter" with a partial view from the controller using AJAX. The content all loads, but the script generated to make the splitter look like a splitter does not fire. If I copy the jQuery call into the console and run it, the splitter turns into what I am expecting.
<script>kendo.syncReady(function(){jQuery("#vertical-18b41377-7c46-4e83-b72c-84e9a6589135").kendoSplitter({"panes":[{"collapsible":false,"scrollable":false},{"collapsible":false,"resizable":false,"size":"100px"}],"orientation":"horizontal"});});</script>
I have loaded content with a splitter in it previously, although this was into a window, not a grid details area.
What can I do to get the splitter to load and not just be a bunch of divs on page?

I've ported my app from .NET Framework MVC to .NET Core 3.1. The Kendo Grid displays OK and fetches data from the controller successfully (no javascript console errors). However despite the fact that 10 records are returned, the grid isn't actually rendering any rows. What could I be doing wrong?
Controller:
public ActionResult FetchUsers([DataSourceRequest] DataSourceRequest request){ var cardivationApi = GetCardivationApi(); var data = cardivationApi.GetUsersFiltered(request); return new JsonResult(data);}
View:
@(Html.Kendo().Grid<UserDtoV1>().Name("grid") .Columns(columns => { columns.Bound(p => p.FirstName).Title(DbRes.T("FirstName", "Labels")) .Filterable(t => t.Cell(cell => cell.Operator("startswith").SuggestionOperator(FilterType.StartsWith).Delay(9999)) .Operators(o => o.ForString(d => d.Clear().StartsWith(DbRes.T("StartsWith", "Labels")).Contains(DbRes.T("Contains", "Labels")))) .Extra(false)); [ cut for brevity ] .Pageable(p => p.PageSizes(true).PageSizes(new[] { 10, 20, 50, 100 }).Messages(t => t.ItemsPerPage(DbRes.T("ItemsPerPage", "Labels")))) .Filterable(ftb => ftb.Mode(GridFilterMode.Menu)) .HtmlAttributes(new { style = "min-height:500px;" }) .ProxyURL(Url.Action("ExcelExport", "Users")) ) .DataSource(dataSource => dataSource .Ajax() .PageSize(10) .ServerOperation(true) .Read(read => read.Action("FetchUsers", "Users")) .Model(model => model.Id(t => t.UserID)) ) )

I am trying to put in a panel bar that is collapsed by default. I took the demo and changed the expanded value to false.
<kendo-panelbar name="project"> <items> <panelbar-item text="Storage" expanded="false"> <items> <panelbar-item text="Wall Shelving"></panelbar-item> <panelbar-item text="Floor Shelving"></panelbar-item> <panelbar-item text="Kids Storag"></panelbar-item> </items> </panelbar-item> </items></kendo-panelbar>
The panel bar items are collapsed but the icon is set to "k-i-arrow-60-up" so it looks like it can still be collapsed.
I am also wanting to put content other than <panelbar-item> in there, so I was going to use the <content> tag instead f the <items> tag an then put a treeview in there. When I use the <content> tag, the content is always show, so I must be using this incorrectly. I know I can do it with the html helpers, but I like how the tag helpers look. Can I still do this with the tag helpers?

Hi everybody
I have a problem with kendo treeview checkboxes
i populated treeview with remote data, it binds correctly. I used "checked" property to send checked checkboxes to view, it works fine too.
i use 2 different method for sending checked node IDs to controller but does not work properly.
method1:
use java script to read nodes recursively and gather IDs then store in hidden field and send to controller but most of the times some nodes doesn't illustrate the check items thoroughly. in other words, I lose near half of checkboxes randomly.
method2:
using checkbox name and template and send checkboxes directly to the controller got same issue.
what can i do for this issue??
thanks
