Hello,

I currently have an ASP.NET MVC application that is primarily composed of a hierarchical grid and custom edit templates. I want to display a simple error page to indicate a failed database operation to the user.

I tried a standard approach adding the following to the Web.Config file: 

<customErrors mode="On"></customErrors>

I also added the following attribute at the beginning of my controller classes:

[HandleError(ExceptionType = typeof(DbUpdateException), View = "Error")]

The error page, Error.cshtml is located in the Views/Shared directory of the application.

I cannot get this to work. I can't even view the error page in the browser. I get a 404 error when I right click on the file and select view in browser.

Are there any general error handling guidelines for Telerik UI for ASP.NET MVC? I looked, but couldn't find anything fairly recent. If any such guidelines / documentation exists, where would I find it?

Thanks

I have a treeView with multiple hierarchy, and only leaf/last node should have checkbox, not any parent should have checkbox.

I have refered many threads and examples. Tried Checkboxes Template but that makes another issue that values did not get binded with checkbox.
I need treeview like (https://jsbin.com/edamuj/131/edit?html,output)

@(Html.Kendo().TreeView()
                                .Name("treeview")
                                .Events(e => e.Select("OnSelectTree").DataBound("OnDataBound")).ExpandAll(true)
                                .Checkboxes(checkboxes => checkboxesName("checkedFiles"))
                                .BindTo((List<DPS.Model.ReviewDocumentTreeViewItemModel>)ViewBag.DocumentTreeData, (Kendo.Mvc.UI.Fluent.NavigationBindingFactory<TreeViewItem> mappings) =>
                                {
                                    mappings.For<DPS.Model.ReviewDocumentTreeViewItemModel>(binding => binding.ItemDataBound((item, category) =>
                                    {
                                        item.Id = category.Id;
                                        item.Text = category.Name;
                                        item.Selected = category.IsSelected;
                                        item.HtmlAttributes.Add("data-allowselection", category.AllowSelection);
                                        item.Expanded = true;
                                        item.Checked = category.IsReviewed;
                                    }).Children(g => g.Items));
                                }))

Hello EveryOne,

I'm trying to change the dataSource of a MultiSelect widget.

This is my MultiSelect (in my CustomEditor):

and i tried in the onOpen_Person function this code :

Now this shows just one item and it's undefined !!

I console.Logged the dataSource and i saw that the "Sid_personen" is undefined .. but in "_data" i found all the items i need .. but it doesn't show them ..

in the attached picture you can see the consoleLogged DataSource.

and this is my ActionMethod:

Hello,

I'm using a dropdown list to display a list of campaigns for a user to choose from. The dropdown list is part of a custom editor template for adding/editing donations. The campaigns are stored in a separate table, that has no cardinal relationship with the underlying donations table used by the template. In this  use case scenario, the campaign table is being used as a lookup. The donation table simply stores the campaign name, nothing else is required beyond that, so no relationship is required.

The campaigns are being stored in a separate table because campaigns are often edited, added, or deleted independent of the rest of the application. There are also too many of them to either hard code or include in the markup.

For some reason, I'm not able to retrieve the data from the campaign table, something I thought would be pretty straightforward.

I'm including a .zip file containing the following relevant files:

Models

Donation.cs 

Campaign.cs 

Controllers

DonationsController.cs

CampaignController.cs

Custom Editor Template

DonationTemplate.cshtml

I'm not sure what I've done wrong here. This seems like it should pretty straightforward. Any advice/feedback would be very much appreciated.

Thank you!

Bom dia, eu tenho uma grid dentro de um popup, esse popup recebe uma model com 5 propriedades e uma lista "opcoes". Eu gostaria de saber como populo essa grid com essa lista da model. Tentei conforme o codigo abaixo, mas sem sucesso.

        @(Html.Kendo().Grid<Entidades.OpcaoPerguntas>(Model.Opcoes)
            .Name("gridOpcao")
            .Columns(columns =>
            {
                columns.Bound(o => o.CodigoOpcao).Visible(false);
                columns.Bound(o => o.Ordem).Visible(false);
                columns.Bound(o => o.DescricaoOpcao).Title("Descrição da Opção");
                columns.Bound(o => o.DescricaoDivisor).Title("Divisor");
                columns.Bound(o => o.DescricaoTipoOpcao).Title("Tipo de Opção");
                columns.Bound(o => o.Meta);
                columns.Bound(o => o.Pontos);
            })
            .Sortable()
            .DataSource(dataSource => dataSource
                .Ajax()
                .Batch(true)
                .ServerOperation(false)
                .Model(m => m.Id(i => i.CodigoOpcao)))

            )
