Hi,
I have to render my partial view in html string (in controller), to return json object.
I found this function that works very well :
01.
public
static
String RenderViewToString(ControllerContext context, String viewPath,
object
model =
null
)
02.
{
03.
context.Controller.ViewData.Model = model;
04.
using
(var sw =
new
StringWriter())
05.
{
06.
//var viewResult = ViewEngines.Engines.FindView(context, viewPath, null);
07.
var viewResult = ViewEngines.Engines.FindPartialView(context, viewPath);
08.
var viewContext =
new
ViewContext(context, viewResult.View, context.Controller.ViewData, context.Controller.TempData, sw);
09.
viewResult.View.Render(viewContext, sw);
10.
viewResult.ViewEngine.ReleaseView(context, viewResult.View);
11.
return
sw.GetStringBuilder().ToString();
12.
}
13.
}
With a kendo grid in partial view, i'm getting a "System.NullReferenceException" on the declaration @(Html.Kendo().Grid(.....
If I return the view with a "Return view" in my controller, it's ok.
My grid:
01.
@(Html.Kendo().Grid((IEnumerable<MAGI.Model.DigicodeImmeuble>)mvDigicode)
02.
.Name(
"gridSyntheseDigicode"
)
03.
.HtmlAttributes(
new
{ style =
"width:100%;height: auto;"
, @
class
=
"k-grid_encart k-grid_nopage"
})
04.
.Columns(t =>
05.
{
06.
t.Bound(c => c.Digicode1.Nom).Title(tabTraduction[701972] +
" 1"
);
07.
t.Bound(c => c.Digicode1.NoDigicode).Title(tabTraduction[100620]);
08.
t.Bound(c => c.Digicode2.Nom).Title(tabTraduction[701972] +
" 2"
);
09.
t.Bound(c => c.Digicode2.NoDigicode).Title(tabTraduction[100620]);
10.
}
11.
)
12.
.Sortable()
13.
.Selectable()
14.
.DataSource(dataSource => dataSource
15.
.Ajax()
16.
.ServerOperation(
false
)
17.
)
18.
.Reorderable(reorder => reorder.Columns(
true
))
19.
.Events(events => events.DataBound(
"onDataBoundGridStandard"
))
20.
)
mvDigicode and tabTraduction are not null.
That's work with the kendo chart module.
What's wrong with the grid ?
Many thanks,
Hi,
We are using a detail row on one of our grids, but have noticed that there are a couple of issues with the way we have done it and I am wondering if there is a way to do the following:
1. When we re-order the columns on the main grid, re-order the same columns on the detail row.
2. When we re-size the columns on the main grid, re-size them on the detail row.
The problem is that we have hard coded the order currently, but are allowing the user the ability to re-order, thus presenting us with the issues above.
Is there an easy way of achieving the above, or will it be a case of manually manipulating them both with javascript?
Cheers,
Gareth
Is there are document that maps the MVC Razor syntax to the raw Kendo UI notation?
I find several examples using Kendo UI that suit my needs but I need to convert them to run in an MVC project.
It's not always clear how the syntax matches from one to the other.
Thanks,
Ken
Hello, I am unable to get data into my kendo grid. I have looked at many other threads but nothing has helped so far. I want to get the data from my controller / model but I am not sure if i am trying to do it correctly
VIEW
@model MyProject.Models.POApprovalViewModel
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
@{
ViewBag.Title = "PO Approval";
}

"container"

{
columns.Bound(model => model.PoId);
columns.Bound(model => model.PoStatus);

When the user clicks Update the cell in the grid isn't being populated with the EditorTemplate hyperlink value.

Hi,
in former WebForm projects I was using asp:DropDownList mostly in these kind of scenarios:
1) The DL was fully rendered server side and the selectable values have been populated using Object/SQL/LinqDataSource on the server.
2) The DL was two-way-bound (by the Bind or Eval statement) to a property of an arbitrary data model, e.g. in the context of a ListView or FormView.
To give you an example of the use case: Say a "status" property in a model need to have values like "On", "Off", "Unknown" and nothing else. An ObjectDataSource ensured, that the DL only contained the values for selection. Then the real model was queried in order to find the selected value and that was selected after Page_Load automatically. Once the user changed the selected value in the "status" DL, the new value was posted back to the server.
That worked fine.
I know how to achieve 1) in the "Kendo World", but I'm wondering, how I could simultaneously "two-way-bind" the DL to another model in order to set the "SelectedItem" form another data model as well as to POST finally changes made by the user.
Any pointer welcome
TIA
I have a custom template for editing a scheduler event. In that template I have a grid to edit an array that is part of my model:
@(Html.Kendo().Grid<Excent.Apps.Web.Solo.Models.MeetingStudentViewModel>(Model.Students)
.Name("StudentsGrid")
.Columns(columns =>
{
columns.Bound(m => m.MeetingStudentID).Hidden();
columns.Bound(m => m.FullName).Title("Student");
columns.Bound(m => m.Goals);
})
.BindTo(Model.Students)
.DataSource(dataSource => dataSource
.Ajax().ServerOperation(false)
.Model(model => model.Id(p => p.MeetingStudentID))
.Model(model => model.Field(o => o.FullName))
.Model(model => model.Field(o => o.Goals))
)
When I display the template the grid is empty.
When I popup a recurrence event, it does not go back to the server where I have logic that is based on the start date before current date.
How do I manipulate the Model that it creates from a recurrence event so that I can hide things based on the start date in my custom template?
in my model I have isPassed but this is based on the first in the series and not the current event..
When my page containing a grid control in MVC 5 with Bootstrap is shrunk to below 1024 px. in width, the grid paging control gets distorted as shown in the attached screenshots.
I'm using a scaffolded MVC UI (2015.3.930) grid inside a default _layout body, i.e. it is being inserted inside a div with classes "container body-content" that have not been modified.
I am using customized bootstrap themes that I generated using the Bootstrap theme builder and the Kendo UI theme builder. To the best of my knowledge, I have only altered colors in the custom themes, not anything related to padding or sizing.
Anyone else seen this problems or have suggestions how to proceed or work around this behavior?
