Hello,

my problem is related to the destroy action, when called a js error is returned (see attached file), but when you call an update on another task the gantt fires the update and then the pending destroy action.

my destroy action:

[AcceptVerbs("Post")]

public

ActionResult ResourcePlanningDeleteLogic([DataSourceRequest] DataSourceRequest request, ResourcePlanningViewModel ResourcePlanning)

{

if (ResourcePlanning != null && ModelState.IsValid)

{

_resourcePlanningService.Deletelogic(ResourcePlanning);

}

return Json(new[] { ResourcePlanning }.ToDataSourceResult(request, ModelState));

}

my gantt:

@(Html.Kendo().Gantt<ResourcePlanningViewModel, ResourcePlanningDependencyViewModel>

()

.Name("gantt")

.Columns(columns =>

{

columns.Bound(c => c.Title).Title("Pianificazione").Width(150).Editable(false).Sortable(true);

columns.Bound(c => c.Start).Format("{0: dd/MM/yyyy}").Title("Data Da").Width(50).Editable(false).Sortable(true);

columns.Bound(c => c.End).Format("{0: dd/MM/yyyy}").Title("Data A").Width(50).Editable(false).Sortable(true);

columns.Bound(c => c.ConsRuleHours).Title("H Reg Cons").Width(60).Editable(false).Sortable(true);

columns.Bound(c => c.IsFrozen).Title("Congelata").Width(50).Editable(false).Sortable(false);

})

.Views(views =>

{

views.DayView();

views.WeekView(weekView => weekView.Selected(false)).DayHeaderTemplate("#=kendo.toString(start, 'dd/MM')#");

views.WeekView(weekView => weekView.Selected(false)).WeekHeaderTemplate("#=kendo.toString(start, 'D')# - #=kendo.toString(kendo.date.addDays(end, -1), 'D')#").Selected(true);

views.MonthView(monthView => monthView.Selected(false).MonthHeaderTemplate("#=kendo.toString(start, 'M')#")).WeekHeaderTemplate("#=kendo.toString(start, 'dd/MM')#");

})

.Height(700)

.ShowWorkHours(false)

.ShowWorkDays(false)

.Snap(false)

.Toolbar(tb => tb.Pdf())

.DataSource(d => d

.Model(m =>

{

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

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

m.Field(f => f.Expanded).DefaultValue(false);

})

.Read(read => read.Action("ResourcePlanningRead", "ResourcePlanning"))

.Destroy("ResourcePlanningDeleteLogic", "ResourcePlanning")

.Update(update => update.Action("ResourcePlanningUpdate", "ResourcePlanning").Data("onUpdateCreate"))

)

.DependenciesDataSource(d => d

.Model(m =>

{

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

m.PredecessorId(f => f.PredecessorID);

m.SuccessorId(f => f.SuccessorID);

})

.Read("ReadResourcePlanningDependencies", "Gantt")

)

.Pdf(pdf => pdf

.FileName("Pianificazione Risorse.pdf")

.ProxyURL(Url.Action("Pdf_Export_Save", "Gantt"))

)

.Editable(editable => editable.Create(false)

.Resize(false)

.DragPercentComplete(false)

.Reorder(false)

.DependencyCreate(false)

.DependencyDestroy(false)

.Confirmation(true)

.Destroy(true)

.Move(false)

.TemplateId("TaskEditorTemplate")

)

.Messages(m => m.Save("Salva")

.Cancel("Annulla")

.Destroy("Cancella")

.DeleteTaskConfirmation("Sei sicuro di voler cancellare la pianificazione?")

.DeleteTaskWindowTitle("Cancella Pianificazione")

.Editor(e => e.EditorTitle("Aggiorna Pianificazione")

.AssignButton("Aggiungi Regola di Consuntivazione")

.ResourcesEditorTitle("Regola di Consuntivazione"))

.Views(v => v.Day("Giornaliera")

.Week("Settimanale")

.Month("Mensile"))

.Actions(a => a.Pdf("Esporta in PDF"))

)

Is there maybe a data error that prevents the first call to the destroy action?

Documentation for Core 3 and razor pages?

Is there any documentation available on how to get Grid working in razor pages with core 3? All I can find is either incomplete or for MVC.

Specifically I'm looking for something that documents how to pass in page index/size so that the data provider function can only fetch the rows needed from the DB. So either a custom reader or something.

The official docs don't have anything.

I've found the razor pages examples on github here : https://github.com/telerik/ui-for-aspnet-core-examples/tree/master/Telerik.Examples.RazorPages/Telerik.Examples.RazorPages

But they don't have any explanation about why things are done the way they are in each case and what specifically is needed to make things work in razor.

I've tried to adapt those examples in my own case but although I can get the grid to call the read method, the grid remains empty.

Custom Popup Edit Template troubles

Hi,

I have a template that I want to display certain controls if I am editing and others if I am creating new.

I have the code shown below but it does not work. It seems that the template is initialized at the time the parent is loaded.

How can I display the dropdown list in create mode and the textbox in edit mode?

The code below doesn't work but shows what I am trying to do.

Thanks … Ed

<div class="form-group">

<label class="LabelStyle">Vial</label>

@{

if (Model != null && Model.IsCreatingNew)

{

@(Html.Kendo().DropDownListFor(m => m.VialId)

.AutoBind(true).DataValueField("VialId").DataTextField("VialName")

.DataSource(source =>

{

source.Ajax()

.Read(r => { r.Url("?handler=VialsRead").Data("forgeryToken"); });

}).HtmlAttributes(new { style = "width:150px" }))

<span asp-validation-for="VialId" class="text-danger"></span>

}

else

@(Html.TextBoxFor(m => m.VialName, new { @class = "border-0", @readonly = "true", @style = "width:50px; margin-top:-8px" }))

}

</div>

Update UI grid using response data from Ajax call

Hi,

I'm using the UI grid in ASP.NET Core using local data. The grid is populated using the page model.

If the user wishes to delete a record, after confirmation, I use an Ajax call to the controller action to perform some magical work and delete the selected record. The ajax call returns successfully, with the updated record set...minus the recently deleted record.

For the life of me, I can't get the newly updated json dataset to refresh the grid. Is this even possible?

Page model

public class RoleListViewModel {

public string GridTitle { get; set; }

public IEnumerable<RoleGrid> RoleList { get; set; }

}

Page code with the grid.

@(Html.Kendo().Grid<RoleGrid>(Model.RoleList)

.Name("roleGrid")

.Columns(columns => {

columns.Bound(m => m.RoleId).Hidden();

columns.Bound(m => m.Name)

.Width(100)

.Title("Name");

columns.Bound(m => m.Description)

.Width(212)

.Title("Description");

columns.Command(command => {

command.Custom("EditRole")

.Text("Edit")

.HtmlAttributes(new { @class = "ds-button", @style = "color: #000000; border: 1px solid #000000;" })

.Click("editRole");

command.Custom("CopyRole")

.Text("Copy")

.HtmlAttributes(new { @class = "ds-button", @style = "color: #000000; border: 1px solid #000000;" })

.Click("copyRole");

command.Custom("DeleteRole")

.Text("Delete")

.HtmlAttributes(new { @class = "ds-button", @style = "color: #000000; border: 1px solid #000000;" })

.Click("deleteRole");

})

.Width(100);

})

.HtmlAttributes(new { style = "height: 517px; color: #323232; font-weight: 400; font-size: 14px;" })

.Pageable(pageable => pageable

.Input(true)

.PreviousNext(true)

.Refresh(true)

.PageSizes(true)

)

.Filterable()

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

.Selectable(select => select

.Mode(GridSelectionMode.Single)

.Type(GridSelectionType.Row)

)

.Sortable(s => s.AllowUnsort(false))

.Search(s => {

s.Field(c => c.Name);

s.Field(c => c.Description);

})

.DataSource(dataSource => dataSource

.Ajax()

.ServerOperation(false)

.Model(model => {

model.Id(m => m.RoleId);

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

model.Field(m => m.Description);

})

.PageSize(10)

)

Controller delete method

public async Task<ActionResult> DeleteAjax([DataSourceRequest]DataSourceRequest request, string roleId) {

if (roleId != null) {

//do some magical code here after selected record is deleted.

return Json(GetRoles().ToDataSourceResult(request));

}

else {

return Json(GetRoles().ToDataSourceResult(request));

}

And finally, the jquery code to handle deleting the selected record

function deleteRole(e) {

e.preventDefault();

var grid = this;

var row = $(e.currentTarget).closest("tr");

selectedRole = this.dataItem($(e.currentTarget).closest("tr"));

$('#confirmDeleteItem').text('Delete the ' + selectedRole.Name + ' role?');

wnd.center().open();

$("#yes").click(function () {

wnd.close();

$.ajax({

type: "POST",

url: '@Url.Action("DeleteAjax", "Role")',

data: { roleId: selectedRole.RoleId },

dataType: "json",

success: function (response) {

var grid = $('#roleGrid').data('kendoGrid');

//response.data returns an array of object with roleId, name and description

//the following call clears out the grid data but the grid still shows the correct # of records left

grid.dataSource.read(response.data({ RoleID: roleId, Name: name, Description: description }));

}

});

$("#no").click(function () {

wnd.close();

});

}

Any suggestions on how to best load the response array after the ajax call?

I realize this is not ideal as it's not server or client side dedicated.

Thanks.

Jason
