Disable filter operators for all columns in row filter mode

Hi

Is it possible to disable the operators button for all cells (in row filter mode) without having to apply it to every column.

At the moment I have the code below but ideally just want this applied at a more global level

columns.Bound(c => c.JobTitle).Width(400).Filterable(f => f.Cell(cell => cell.ShowOperators(false)));

Thanks

Andy

Id field is required even though not part of the grid

I'm working with a grid in asp.net mvc, where I have a model containing several properties. One of its properties (Id) is a Guid. Whenever I try to create a new row in my grid, entering all details (Id is automatically generated by a backend server when saved) and press "Update", I get an error saying "The Id field is required". Is there a way to get around this?
I suspect the Guid-type to be the one causing trouble here.
Here's my grid:

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

.Name("grid")

.Columns(columns =>

{

columns.Bound(p => p.Displace);

columns.Bound(p => p.FishingNectOd);

columns.Bound(p => p.Length);

columns.Bound(p => p.Model);

columns.Bound(p => p.Name);

columns.Bound(p => p.Supplier).Width(150);

columns.Bound(p => p.TagId);

columns.Bound(p => p.ToolOd);

columns.Bound(p => p.Type);

columns.Bound(p => p.Weight);

columns.Command(command => { command.Edit(); command.Destroy(); }).Width(180);

})

.ToolBar(toolbar => toolbar.Create())

.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("ToolPopUpTemplate"))

.Pageable()

.Sortable()

.Scrollable()

.HtmlAttributes(new { style = "height:500px;" })

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(10)

.Events(events => events.Error("error_handler"))

.Model(model => model.Id(toolModel => toolModel.Weight))

.Create(update => update.Action("EditingPopup_Create", "ToolManagement"))

.Read(read => read.Action("EditingPopup_Read", "ToolManagement"))

.Update(update => update.Action("EditingPopup_Update", "ToolManagement"))

.Destroy(destroy => destroy.Action("EditingPopup_Destroy", "ToolManagement"))

))

Template:

@using Services.Models.Tool

@model ToolModel

<div class="editor-label">

@(Html.LabelFor(model => model.Displace))

</div>

<div class="editor-field">

@(Html.TextBoxFor(model => model.Displace))

</div>

<div class="editor-label">

@(Html.LabelFor(model => model.FishingNectOd))

</div>

<div class="editor-field">

Controller:

public class ToolManagementController : Controller

{

private static readonly ILog Log = LogManager.GetLogger("ToolManagementController.class");

public ToolServiceClient ToolService { get; set; }

public ToolManagementController()

{

try

{

ToolService = new ToolServiceClient();

}

catch (Exception e)

{

Log.Error(e);

}

}

// GET: ToolManagement

public ActionResult Tools()

{

return View();

}

public ActionResult EditingPopup_Read([DataSourceRequest] DataSourceRequest request)

{

ToolContract[] list = ToolService.GetTools();

return Json(list.ToDataSourceResult(request));

}

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult EditingPopup_Create([DataSourceRequest] DataSourceRequest request, ToolModel tool)

{

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

{

{

Displace = tool.Displace,

FishingNectOD = tool.FishingNectOd,

Length = tool.Length,

Model = tool.Model,

Name = tool.Name,

Supplier = tool.Supplier,

TagId = tool.TagId,

ToolOD = tool.ToolOd,

}

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

}

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult EditingPopup_Update([DataSourceRequest] DataSourceRequest request, ToolModel tool)

{

if (tool != null)

{

ToolService.DeleteTool(tool.Id);

}

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

}

}

Finally, the model:

public ToolModel(ToolContract toolContract)

{

ToolContract = toolContract;

}

public ToolModel()

{

}

private ToolContract ToolContract

{

get { return _toolContract ?? (_toolContract = new ToolContract()); }

set { _toolContract = value; }

{

get { return ToolContract.Displace; }

set { ToolContract.Displace = value; }

}

public double? FishingNectOd

{

get { return ToolContract.FishingNectOD; }

set { ToolContract.FishingNectOD = value; }

}

[ScaffoldColumn(false)]

public Guid Id

{

get { return ToolContract.Id; }

set { ToolContract.Id = value; }

}

public double? Length

{

get { return ToolContract.Length; }

set { ToolContract.Length = value; }

}

public string Model

{

get { return ToolContract.Model; }

set { ToolContract.Model = value; }

}

public string Name

{

get { return ToolContract.Name; }

set { ToolContract.Name = value; }

}

public string Supplier

{

get { return ToolContract.Supplier; }

set { ToolContract.Supplier = value; }

}

public string TagId

{

get { return ToolContract.TagId; }

set { ToolContract.Supplier = value; }

}

[Display(Name = "Outer Diameter")]

public double? ToolOd

{

get { return ToolContract.ToolOD; }

set { ToolContract.ToolOD = value; }

}

public string Type

{

get { return ToolContract.Type; }

set { ToolContract.Type = value; }

}

public double? Weight

{

get { return ToolContract.Weight; }

set { ToolContract.Weight = value; }

}

}

[Solved] Export to PDF, new page every time a certain field changes

Is it possible to make the PDF work in a way so every time a certain field changes, it starts on new page? For example if the field I want to determine this is "CarMakes" and when its value changes from BMW to Ferrari, Ferrari starts on a new page in the PDF document?

[Solved] (PDF Export) One page per group

Hello,

is it possible when using the built-in PDF export functionality to make it list each grouped section (created via Ajax().Group()) onto its own page?

I'm required to create two types of reports. One that exports all items combined into a single report and a second one that exports based on grouping of a specific column. I have the grid grouped correctly but when exporting, I need each group on it's own page rather than displayed all in one grid.

Is there built-in functionality for this or a known work-around?

Thank you.

Editable Grid DDL

Hello,

I'm looking at the "editing_custom" grid example for ASP.NET MVC and wondering if there is a way to bind the drop down without ViewData? I would like to use a generic ViewModel with Value and Text pairs similar to our existing MVC solution. I am asking this because there is no reusability when populating the CategoryViewModel and ViweData in the controller. Only the EditorTemplate can be reused.

@model Kendo.Mvc.Examples.Models.CategoryViewModel

@(Html.Kendo().DropDownListFor(m => m)
.DataValueField("CategoryID")
.DataTextField("CategoryName")
.BindTo((System.Collections.IEnumerable)ViewData["categories"])
)

Also, how do you add a "--Select a Category--" at the top of the dropdown list (in your example and in a non-ViewData approach)?

Thanks

John
