I'm using the Kendo Grid control to display some data and it's working OK. This is the code:
#(Html.Kendo().Grid<MyModel>()
.Name("MyGrid")
.ToolBar(toolbar =>
{
toolbar.Create().Text("Add New Line").HtmlAttributes(new { #Class = "btn btn-primary" });
})
.Columns(columns =>
{
columns.Bound(p => p.Description).HtmlAttributes(new {style = "font-size: 9pt;"});
columns.Bound(p => p.Value);
columns.Command(cmd =>
{
cmd.Edit();
cmd.Destroy();
}).Width(200);
})
.Editable(editable => editable.Mode(GridEditMode.InLine))
.Selectable(s => s.Mode(GridSelectionMode.Multiple).Type(GridSelectionType.Row))
.DataSource(data => data
.Ajax()
.Events(events => events.Error("error_handler"))
.Model(model => model.Id(p => p.Id))
.ServerOperation(false)
.Read(read => read.Action("ReadAction", "MyController"))
.Create(create => create.Action("CreateAction", "MyController"))
.Update(update => update.Action("UpdateAction", "MyController"))
.Destroy(delete => delete.Action("DeleteAction", "MyController"))
))
The code above is working without any problem. Now, what I'm trying to implement is to display the same data using the MVVM pattern. I mean, I would like to have the same operations (create, update, delete) in my viewmodel without calling the server actions of my controller as the code above does.
I have google it for a while but without any luck.
Any help would be very appreciate

I have a Hierarchical grid and I'm trying to add a custom editor for pop-up editing. When I add the template to the child grid and click on the "edit" button, i get a invalid template error. If i add that same template to the parent, it works fine.
Here is the error in console:
Uncaught Error: Invalid template:'
Here is the code
#(Html.Kendo().Grid<ParentViewModel>()
.Name("GridAdjax")
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Events(events => events.Error("error_handler"))
.Read(read => read.Action("Read", "controller"))

{
model.Id(c => c.Id);
})
.ServerOperation(false)

If anyone experiences this issue in the future, the problem was actually in my custom pop-up editor template. I had a data validation message on one of the input boxes set as "Please enter your account #". The "#" was being interpreted as a template by Kendo. I escaped the # and then was able to get it to successfully load.
I am using a Kendo MVC Grid and i want to have a dropdownlist in one of the cells.
here is my code:
#(Html.Kendo().Grid<RMS.Admin.ViewModel>()
.Name("ResourceGrid")
.Columns(columns =>
{
columns.Bound(c => c.ResourceName);
columns.Bound(c => c.Descritption);
columns.Bound(c => c.ResourceType).ClientTemplate("#=ResourceType#");
columns.Bound(c => c.Approved);
columns.Bound(c => c.IsEnabled);
columns.Bound(c => c.Data).Width(220);
columns.Command(command =>
{
command.Edit();
command.Destroy();
}).Width(172).Title("Edit/Delete");
})
.ToolBar(toolbar => toolbar.Create())
.Editable(editable => editable.Mode(GridEditMode.InLine))
.Scrollable()
.Sortable()
.HtmlAttributes(new { style = "height:800px" })
.Pageable(pageable => pageable
.Refresh(true)
.PageSizes(true)
.ButtonCount(5))
.ClientDetailTemplateId("template")
.DataSource(dataSource => dataSource
.Ajax()
.Model(model =>
{
model.Id(s => s.ResourceId);
model.Field(p => p.ResourceType).DefaultValue(ViewData["defResourceType"] as RMS.Admin.ViewModel.ResourceTypeId);
})
.Create(update => update.Action("CreateResource", "Home", new { resourceTypeId = "#=ResourceType.Id#" }))
.Read(read => read.Action("ReadResource", "Home"))
.Update(update => update.Action("UpdateResource", "Home"))
.Destroy(destroy => destroy.Action("RemoveResource", "Home"))
)
.Events(events => events.DataBound("dataBound"))
)
The problem is that i don't know what clienttemplate is so i don't know what to do with it.
If bound resourcetype with a clienttemplate i can't add new records to the grid, i get the error: Uncaught ReferenceError: ResourceType is not defined
If i remove clienttemplate i can add a record but when i try to save it it says it can't find the id of ResourceType.
basically if you want to use a dropdownlist within a kendo ui grid you have to define an editor template which includes a kendo dropdownlist widget. this means you have to declare the respective cell with the attribute .EditorTemplateName() like this:
.Columns(columns =>
{
columns.Bound(c => c.ResourceName);
columns.Bound(c => c.Descritption);
columns.Bound(c => c.ResourceType).EditorTemplateName("TemplateName");
columns.Bound(c => c.Approved);
columns.Bound(c => c.IsEnabled);
columns.Bound(c => c.Data).Width(220);
columns.Command(command =>
{
command.Edit();
command.Destroy();
}).Width(172).Title("Edit/Delete");
})
the editortemplate has to be stored within folder: Shared/EditorTemplates/TemplateName.cshtml
TemplateName.cshtml should look like this:
#model ModelName
#(Html.Kendo().DropDownList()
.OptionLabel("please select a value")
.Name("ResourceType") <-- the name needs to be equal to the grid cell name
.DataSource(source=>
{
source.Read( read =>
{
read.Action("ActionName", "ControllerName");
})
.ServerFiltering(true);
})
.DataTextField("Name") <-- displays the text of the object
.DataValueField("ID") <-- stores the id of the object
)
hope this will lead you into the right direction.
cheers,
I have the next Kendo Grid, all the events in the models take place, no problem!.
The problem is when I change a value in the grid, it not refresh again.
How I can fix this, or how I can get the event occurring when I do changes on the grid, to manage the grid refresh with JQuery.
#(Html.Kendo().Grid<Corporativo.Model.SolProdVM>()
.Name("SolicitudesProducto")
.Columns(columns =>
{
columns.Bound(e => e.Id_Producto).Width(80).Title("Código");
columns.Bound(e => e.DescProducto).Width(40).Groupable(false).Title("Producto");
columns.Bound(e => e.UM).Width(40).Groupable(false).Title("UM");
columns.Bound(e => e.Precio).Width(40).Groupable(false).Title("Precio");
columns.Bound(e => e.Cantidad).Width(40).Groupable(false).Title("Cantidad");
columns.Bound(e => e.Importe).Width(40).Groupable(false).Title("Importe");
columns.Command(command => command.Custom("Eliminar").Click("elimar_de_solicitud")).Width(25);
})
.Sortable()

{
toolBar.Save().Text("Guardar cambios");
})

model.Field(p => p.Desc_Producto).Editable(false);
model.Field(p => p.UM).Editable(false);
model.Field(p => p.Precio).Editable(false);

})

)
)
There is an Events Method you can call.
#(Html.Kendo().Grid<Model_MVC.Models.OrderGridViewModel>()
.Name("ProposalGrid")
.HtmlAttributes(new { style = "font-size:14px;line-height:2em;width:80%;margin-left:190px;" })
.Columns(columns =>
{
//columns
})
.
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("Orders_Read", "Orders"))
.Events(x => x.Change("JSFunction") )
.Model(model =>
{
model.Id(i => i.OrderId);
model.Field(x => x.OrderId).Editable(false);
})
.PageSize(15)
)
.Pageable()
)
I have use Kendo version 2012.03.1114 and below mention code to add value to model and work fine but when I update the kendo varsion to 2013.3.1119 it will give a error
(TypeError: $(...).data(...).kendoGrid.editable is undefined)
any workaround please?
var model = $('#grid').data().kendoGrid.editable.options.model;
model.set('Name', getNames());
#(Html.Kendo().Grid<ABC.Domain.Entities.user>()
.Name("Grid")
.Columns(columns => {
columns.Command(command => { command.Edit(); }).Width(80);
columns.Bound(u => u.Name).Title("Name").Width(150);
columns.Bound(u => u.Status).Title("Status").Width(70);
columns.Bound(u => u.Address).Title("Address").Width(100); })
.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("userEdit")) .Events(events => events.DataBound("onDataBound").Edit("onEdit"))
.Pageable(paging => paging.PageSizes(new int[] { 5, 10, 20, 50 })
.Refresh(true))
.Sortable() .ToolBar(toolbar => toolbar.Create())
.Resizable(resize => resize.Columns(true))
.Scrollable()
.DataSource(dataSource => dataSource .Ajax() .Model(model => { model.Id(p => p.userKey); }) .PageSize(5) .Events(events => events.Error("error_handler"))
.Read(read => read.Action("user_Read", "User"))
.Update(update => update.Action("User_Update", "User"))
.Create(create => create.Action("User_Create", "User")) ) )
The best overloaded method match for Kendo.Mvc.UI.Fluent.GridEditingSettingsBuilder Mode(Kendo.Mvc.UI.GridEditMode) has some invalid arguments .Filterable() and .Scrollable()
This is the error I get while I run the project which has the KendoUI Grid Control.
The code is similar to what is there in the KendoUI website , however on my project I do get this error. I am able to get the Filterable() option in the intellisense but am not sure why the error is thrown . I can see the error in Firebug and it is not thrown by the webpage as a yellow screen of death.
Any help would be appreciated.
