My grid is build like this:
#(Html.Kendo().Grid<MyProject.Models.DataObjects.MyObject>()
.Name("my-object-grid")
.Columns(columns =>
{
columns.Bound(p => p.ID).Hidden();
columns.Bound(p => p.Name).Width(300);
columns.Command(command =>
{
command.Edit().Text("Modify")
.UpdateText("Save")
.CancelText("Cancel")
.HtmlAttributes(new { style = "width:90px;height:30px;font-size:12px;" });
command.Destroy().Text("Delete").HtmlAttributes(new { style = "width:90px;height:30px;font-size:12px;" });
}).Width(220);
})
.ToolBar(toolbar => toolbar.Create().Text("Add").HtmlAttributes(new { style = "width:120px;height:30px;float:left;" }))
.Editable(editable => editable.Mode(GridEditMode.PopUp)
.Window(win => win.Title("MyObject")).TemplateName("MyObject"))
.Pageable()
.Sortable()
.Scrollable()
.Filterable()
.HtmlAttributes(new { style = "height:430px;" })
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(10)
.Model(model =>
{
model.Id(p => p.ID);
})
.Create(update => update.Action("MyObject_Create", "MyObject"))
.Read(read => read.Action("MyObject_Read", "MyObject"))
.Update(update => update.Action("MyObject_Update", "MyObject"))
.Destroy(update => update.Action("MyObject_Delete", "MyObject"))
.Events(evt => evt.Push("myObjectGridDataSource_push").Error("myObjectGridDataSource_error"))
)
)
And the foolwingo javacript handlers are defined after:
<script type="text/javascript">
function myObjectGridDataSource_push(e) {
alert(e.type);
}
function myObjectGridDataSource_error(e) {
alert(e.status);
}
</script>
The javascript generated by the helper seems to be ok, but the event handlers are never fired when I add/edit/remove some item of the grid. But the requests to the controller are working fine.
Could be this related to the edit mode of the grid (using popup)?
I can't find what I am doing wrong...
Push is invoked during dataSource transport initialization which sets up push notifications. The data source will call this function only once and provide callbacks which will handle push notifications (data pushed from the server).
Push event Detailed information
If you can tell what exactly you are trying to achieve then I can be of a bit more help. Also if you want to catch the event before the record id being udpated or inserted or deleted then push won't do it. You will need to implement the sync event of the grid.

I have a kendo data grid grouped default by a column and I want to edit the grid inline. I don't want the user to group by any other column. While the default grouping works fine, the update event is not fired and the control doesn't go the controller's inline update method. Can you please check where I'm going wrong. Below is the code:
#(Html.Kendo().Grid(Model)
.Name("grdTimesheets")
.Columns(columns =>
{
columns.Bound(p => p.EmployeeId).Hidden(true);
columns.Bound(p => p.FirstName);
columns.Bound(p => p.Monday.Hour).Title("Monday")
.EditorTemplateName("TimesheetMonday");
columns.Command(command =>
{
command.Edit();
command.Destroy();
command.Custom("Add").Text(" ").Click("AddNewTimesheet");
});
})
.Editable(editable => editable.Mode(GridEditMode.InLine))
.Pageable()
.Sortable()
.Groupable(false)
.Scrollable()
.DataSource(dataSource => dataSource
.Ajax()
.Model(model =>
{
model.Id(p => p.EmployeeId);
model.Field(p => p.FirstName).Editable(false);
})
.PageSize(20)
.Update(update => update.Action("EditingInline_Update", "Timesheet"))
.Destroy(destroy => destroy.Action("EditingInline_Destroy", "Timesheet"))
.Group(d=>d.Add(f=>f.FirstName))
)
If I comment out the last line ".Group(d=>d.Add(f=>f.FirstName))", everything works fine but the default grouping goes off.
I know that its a bit late for an answer but I will just leave this here in case that anybody else is having the same problem. Once you group by any column the grid will not fire ".Update(update => update.Action("EditingInline_Update", "Timesheet"))". In order to fix this you would need to add OnEditEvent for the grid and in the javascript function to attach an event to the textbox/dropdown or whatever control you have there. Sample below:
.Events(events => events.Edit("grid_edit")) this is in the view
javascript:
function grid_edit(e) {
var grid = $('#grid').data('kendoGrid');
var cell = e.container;
var area = cell.find("textarea")
area.on("blur", function() {
// update ur entries here
var areaVal = cell.find("textarea").val(); // this is the new value
// call some ajax to update the value and in the success call grid.dataSource.sync(); to refresh the grid
});}
Also you would need to remove your .Update() for the DataSource because its no longer needed.
So I've got a grid that I believe is all set up correctly. I've confirmed that the data is coming through, and I've even checked that the AJAX call returns a success with the "ToDataSourceResult" JSON data.
Unfortunately, the only problem is that the data doesn't display. This seems to only be an issue on read, as update, create and delete all work. Just can't retrieve the list of all items afterwards.
My controller action looks like this:
public IActionResult Blog_Read([DataSourceRequest] DataSourceRequest request)
{
var blogs = _blogService.GetPosts().Select(post => new BlogPostModel
{
Id = post.Id,
Title = post.Title,
Author = post.Author,
ShortDescription = post.ShortDescription,
Contents = post.Contents,
LastSaved = post.LastSaved,
Published = post.Published,
PublishedOn = post.PublishedOn
});
var result = blogs.ToDataSourceResult(request);
return Json(result);
}
And my Grid View looks like this:
#(Html.Kendo().Grid<BlogPostModel>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(p => p.Title);
columns.Bound(p => p.Author).Width(120);
columns.Bound(p => p.LastSaved).Width(120);
columns.Bound(p => p.Published).Width(120);
columns.Command(command => { command.Edit(); command.Destroy(); }).Width(250);
})
.ToolBar(toolbar => toolbar.Create())
.Editable(editable => editable.Mode(GridEditMode.PopUp))
.Pageable()
.Sortable()
.Scrollable()
.HtmlAttributes(new { style= "height:600px;"})
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Events(events => events.Error("error_handler"))
.Model(model => model.Id(p => p.Id))
.Create(update => update.Action("Blog_Create", "BlogAdmin"))
.Read(read => read.Action("Blog_Read", "BlogAdmin"))
.Update(update => update.Action("Blog_Update", "BlogAdmin"))
.Destroy(update => update.Action("Blog_Delete", "BlogAdmin"))
)
.Deferred()
)
The correct JSON is returned, no javascript errors in the console, so I'm a little confused as to what this could be. Any help would be greatly appreciated.
I solved this by adding
services.AddMvc().AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());
to my Startup.cs ConfigureServices method.
I am a new babie for Kendo UI for MVC, I am trying to customise row color when doing batch editing for a grid, I looked in the internet but couldn't find any info. After editing a cell for batch editing grid by default Kendo add a small red spot at the top left hand side of the cell , what I want to achieve after editing any cell the whole row for that record change change it color. I would like to change the row to green for example to give the user more visibility what row have been edited before click save. I would really app if someone could help me.
code
#(Html.Kendo().Grid<MvcKendo.Models.Availablity>().Name("grid")
.Columns( columns => {
columns.Bound(c => c.Id);
columns.Bound(c => c.TimeFrom);
columns.Bound(c => c.TimeTo);
})
.DataSource(datasource => datasource.Ajax().PageSize(5)
.Read("GetDataAvailablity","Home"))
.ClientDetailTemplateId("template")
)
<script id="template" type="text/kendo-tmpl">

You can make use of the save event in Kendo grid to achieve this
C#
.Events(events => events.Save("onSave")
Javascript
function(e) {
$(e.container).closest("tr").css("background-color","lightgreen");
}
Here's the fiddle for the sample in JS
please go through the code below. In below grid, I've a column with hyperlink. I want to open a kendo window when i click on the particular link. How can i achieve this. Currently it is navigating to some other page.
#model IEnumerable<WeBOC.Support.Entities.ImportUnit>
#{
ViewBag.Title = "Import Units";
}
<h2>Import Units</h2>
#(Html.Kendo().Grid(Model)
.Name("Grid")
.Columns(columns =>
{
columns.Bound(p => p.UnitNbr).Width(150).ClientTemplate(#Html.ActionLink("#=UnitNbr#", "UnitInspector", new { id = "#=UnitId#" }).ToHtmlString()).Title("Unit No.");
columns.Bound(p => p.VIRNbr).Width(150).Title("VIR No.");
columns.Bound(p => p.BLNbr).Width(150).Title("BL No.");
columns.Bound(p => p.IGMStatus).Width(80).Title("IGM Status");
columns.Bound(p => p.LineCode).Width(80).Title("Line Code");
columns.Bound(p => p.Arrived).Format("{0:dd/MM/yyyy HH:mm}").Width(150).Title("Arrived");
})
.Groupable()
.Pageable()
.Sortable()
.Filterable()
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.ServerOperation(false)
)
)
How to create hyperlinks, how to invoke javascript functions and how to pass parameters is all covered in this section of the documentation.
Why don't you change your client template to a simple html-element such as an a-element and assing a javascript function to this element which opens your window?
...
columns.Bound(p => p.UnitNbr).Width(150).ClientTemplate("<a id="myId>Unit No.</a>);
...
and then use jquery:
$("#myId").click(function() {
$("#kendoWindow").data("kendoWindow").open();
});
Adjust your template so the links have a css class:
columns.Bound(p => p.UnitNbr).Width(150).ClientTemplate(#Html.ActionLink("#=UnitNbr#", "UnitInspector", new { id = "#=UnitId#" }, new { #class="someclass" }).ToHtmlString()).Title("Unit No.");
Then use jQuery:
$(document).on("click", ".someclass", function (e) {
e.preventDefault();
var address = $(this).attr("href");
$("<div/>").kendoWindow({
content: address
}).data("kendoWindow").open();
});
I have Kendo Grid with delete command. When I click delete and then click "save change" on the left top of grid, real data is not sent to server. data has key/create date/other fields. I used Odata service. In debug mode, key = 0 and create date = 1/1/0001. Anyone got a clue what is happening here?
#(Html.Kendo().Grid<OData.proxySvc.table1>()
.Name("MyGrid")
.Columns(columns =>
{
columns.Bound(f => f.key).Visible(false);
columns.Bound(f => f.UserName).Title("Name");
columns.Command(command => {
command.Destroy();
}).Title("Action").Width(90);
})
.ToolBar(toolbar =>
{
toolbar.Save();
})
.Editable(editable => editable.Mode(GridEditMode.InCell))
.Sortable()
.Scrollable(s => s.Height("100px"))
.Filterable()
.DataSource(ds => ds
.Ajax()
.Batch(true)
.ServerOperation(false)
.Model(model => model.Id(p => p.key))
.Destroy("Delete","Home")
))
in control file, there is action:
// no [Httppost] attributes. if [HttpPost] attributes exist, no event fire
public ActionResult Delete([DataSourceRequest]DataSourceRequest request,
[Bind(Prefix = "models")]IEnumerable<table1> tbl1)
{
var context = CreateOdataServiceContext();
foreach (var t1 in tbl1)
{
var x = context.table1.Where(r => r.key == t1.key).FirstOrDefault();
if (x!=null)
{
context.DeleteObject(x);
context.SaveChanges();
}
}
}
