I am using custom binding and have followed this documentation http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/grid/custom-binding

I read the data from a database, I am wondering if there is a way NOT to do this every time the user goes to a new page, changes the sorting, filtering, page size etc?

Regards, Jill-Connie Lorentsen

MVC Grid - Export to Excel, PageSize

We are using the GridRouteValues() to save the user's preferred page size for grids.

When the Export to Excel function is used with the All Pages option set to True, it sets the PageSize in the RouteValues to the total rows to be exported. This causes our saved user's page size to be set to that value. We don't want to save that PageSize when it's for the Export to Excel, but I can't see a way to distinguish that call to the controller from the others.

Any ideas?

Inline Edit and Update with ViewModel

Hello,

I have a kendo grid in my MVC application. I have a viewmodel that shows related data in the grid, when the user edits a row using inline editing I need it to update the database via the viewmodel. How is this done?

My grid code

@(Html.Kendo().Grid<Multiple_Table_Post.ViewModels.MultiPostViewModel>()

.Name("Grid")

.Columns(columns =>

{

columns.Bound(c => c.id).Title("ID");

columns.Bound(c => c.parent_id).Title("PID");

columns.Bound(c => c.vessel_name).Title("Name")

.ClientTemplate("<a href='" + Url.Action("Details", "Vessels") + "/#=parent_id#'" + ">#=vessel_name#</a>");

columns.Bound(c => c.vessel_location).Title("Location");

columns.Bound(c => c.vessel_mmsi).Title("MMSI");

columns.Bound(c => c.vessel_bhp).Title("BHP");

columns.Bound(c => c.vessel_omid).Title("OMID");

columns.Command(command =>

{

command.Edit()

.Text("Edit")

.UpdateText("Update")

.CancelText("Cancel");

}).Width(110);

}

)

.Pageable()

.Editable(editable => editable.Mode(GridEditMode.InLine))

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(7)

.Read(read => read.Action("data_read", "InlineEdit"))

.Update(update => update.Action("data_update", "InlineEdit"))

.Sort(sort => sort.Add("id").Descending())

.Model(model =>

{

model.Id(p => p.id);

})

)

The viewmodel

using System;

using System.Collections.Generic;

using System.ComponentModel.DataAnnotations;

using System.Linq;

using System.Web;

using Multiple_Table_Post.Models;

namespace Multiple_Table_Post.ViewModels

{

public class MultiPostViewModel

{

// #Vessel

public int id { get; set; }

[Display(Name = "Name [Vessels(table)]")]

[Required(ErrorMessage = "Vessel name cannot be left blank")]

public string vessel_name { get; set; }

[Required(ErrorMessage = "Location cannot be left blank")]

[Display(Name = "Location [Vessels(table)]")]

[UIHint("LocationEditor")]

public string vessel_location { get; set; }

[Display(Name = "MMSI [Vessels(table)]")]

public string vessel_mmsi { get; set; }

// #Vessel Details

// Without primary key ID.

[Display(Name = "OMID [Vessels Details(table)]")]

public Nullable<System.DateTime> vessel_omid { get; set; }

[Display(Name = "BHP [Vessels Details(table)]")]

[Required(ErrorMessage = "BHP cannot be left blank")]

public Nullable<decimal> vessel_bhp { get; set; }

[Display(Name = "PID [Vessels Details(table)]")]

public Nullable<int> parent_id { get; set; }

[Display(Name = "DECK [Vessels Details(table)]")]

public Nullable<decimal> vessel_deck { get; set; }

public virtual ICollection<vessel_details> vessel_details { get; set; }

}

Controll

public ActionResult data_read([DataSourceRequest]DataSourceRequest request)

{

var datacontext = db.vessel_details.AsQueryable();

IQueryable<MultiPostViewModel> thevessel = from c in datacontext

select new MultiPostViewModel

{

id = c.id,

parent_id = c.vessel.id,

vessel_name = c.vessel.vessel_name,

vessel_location = c.vessel.vessel_location,

vessel_mmsi = c.vessel.vessel_mmsi,

vessel_omid = c.vessel_omid,

vessel_bhp = c.vessel_bhp,

};

DataSourceResult result = thevessel.ToDataSourceResult(request);

return Json(result);

}

Controller : UPDATE Grid Data

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult data_update([DataSourceRequest]DataSourceRequest request, VesselsViewModel vessel)

{

if (ModelState.IsValid)

{

var entity = new vessel();

entity.id = vessel.id;

entity.vessel_name = vessel.vessel_name;

entity.vessel_location = vessel.vessel_location;

entity.vessel_mmsi = vessel.vessel_mmsi;

db.vessels.Attach(entity);

db.Entry(entity).State=EntityState.Modified;

db.SaveChanges();

}

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

}

The update code is where I am stuck, how can I get this code to use my view model and update the related tables?? Anyone ever had this problem?

Thanks

Grid Edit PopUp Window - Center on Resize

I have a Kendo Grid that is formatted to edit in a popup window with a custom template:

.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("MyEditor").Window(w => w.Resizable().Events(e => e.Resize("popupResize"))))

That popup edit window template ("MyTemplate") has multiple controls on it which includes a Kendo TabStrip. One of the tabstrip items contains another Kendo Grid. Depending on the datasource of that grid, the width and height of the popup window may change. This may even take the edit popup window partially off the screen.

The problem is that the Resize event (which I'm subscribing to as shown above) of the grid popup window doesn't fire when the window's size changes due to changes in the content. It only fires if the user resizes the window with their mouse.

Is there a way to know when the content width/height of a popup edit window changes so I can call the center() method on the edit popup window?

New grid filter operators not working correctly

I posted this in the JavaScript forum three days ago and have yet to get a response. Maybe someone from Telerik will pay attention if I post it here instead.

I recently created a new project with the latest Kendo code. The project has numerous grids and most of them use filter rows. I do all my grid filtering, sorting, paging, and grouping on the server side using the DataSourceRequest object that the grid passes through the grid's data source read action. I noticed that in the latest version of Kendo, there are four new filter operations: Is Null, Is Not Null, Is Empty, and Is Not Empty. Those seem like good options to have for filtering. The problem is that, in their current form, they're unusable for server side filtering. The filters in the DataSourceRequest object are not providing the critical Member property when using any of the new operations so I have no way of knowing which columns in my database the new filters should be applied to. Can you tell me if you are aware of this issue and, if so, when you will fix it? Also, is there a way to keep those operations (or any of the others for that matter) from showing up in the list of filter operators? Thanks.

FileBrowser not showing

I've been using the demo to set up an Image and File browser for my editor.

The image browser seems to be working fine but the file browser doesn't open, I just get the standard window pop up.

I am have added the custom controller code in the same way, inherited and maintained the naming, and using the default routing for my application.

Any ideas of what could be wrong?

VIEW:

@(Html.Kendo().Editor()
.Name("Description")
.ImageBrowser(imageBrowser => imageBrowser
.Image("~/Content/ProjectFiles/" + (Model.RelatedProjectId > 0 ? Model.RelatedProjectId.ToString() + "/" : "") + "{0}")
.Read("Read", "ImageBrowser")
.Create("Create", "ImageBrowser")
.Destroy("Destroy", "ImageBrowser")
.Upload("Upload", "ImageBrowser")
.Thumbnail("Thumbnail", "ImageBrowser"))
.FileBrowser(fileBrowser => fileBrowser
.File("~/Content/ProjectFiles/" + (Model.RelatedProjectId > 0 ? Model.RelatedProjectId.ToString() + "/" : "") + "{0}")
.Read("Read", "FileBrowser")
.Create("Create", "FileBrowser")
.Destroy("Destroy", "FileBrowser")
.Upload("Upload", "FileBrowser"))
)

CONTROLLER

public class FileBrowserController : EditorFileBrowserController
{
private const string ContentFolderRoot = "~/Content/";
private static readonly string[] FoldersToCopy = new[] { "~/Content/shared/" };

etc....

Grid Column Background Color Multiple Pages

Is there a way to set the background color of all cells in a column across multiple pages of a grid? I have a javascript function that sets the background color, however, as soon as I change pages, my highlighting goes away.

Thanks,

Matt
