I am trying to create a grid that has 5 static parent categories that when expanded will use AJAX to show the data within those categories. Since the categories are static I just create a model, with a Name and Type property, in the controller action and bind them directly to the grid

@(Html.Kendo().Grid(Model.Categories)

.Name("CategoryGrid")

.Columns(c =>

{

c.Bound(b => b.Name);

c.Bound(b => b.Type);

})

.ClientDetailTemplateId("result-template")

)

<script id="result-template" type="text/kendo-tmpl">

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

.Name("#=Name#_child")

.Columns(c =>

{

c.Bound(b => b.ID);

c.Bound(b => b.Description);

})

.DataSource(ds => ds

.Ajax()

.PageSize(20)

.Read(r => r.Action("ChildSearch", "Search", new { Type = "#=Type#" }))

)

.Pageable()

.Selectable()

.ToClientTemplateId()

)

</script>

I unfortunately can't share a screen shot as my dev box doesn't have an internet connection today, but the result is all the columns of the parent grid are offset to the left by 1.

The values for the Name column and an empty header appears in the first column.

The values for Type and the header "Name" appears in the second column.

A blank view, meaning the row styles cut off at the right end of the 2nd column, and the header "Type" appear in the third column.

So my question would be: Why is this happening?

Thanks

Deferred object in remove

Hi,

I've run into a bit of a snag within the onRemove javascript method. We have a custom confirm dialog in our application and I'd like to trigger that when removing files from the upload, there does not seem to be any support in the remove method for deferred objects. I'm just not sure how I can proceed. Should I try to override the click function on the remove button so it triggers a different method that then triggers the remove event of the actual upload control? Is there a way to bypass the javascript onRemove, but still process the rest of the remove logic? Is it possible to have the remove workflow delay until my deferred dialog box has completed?

Thanks,

Kevin

}

alert('onChange');

}

function onClose()

{

alert('close');

}

function resizeGrid() {

var gridElement = $("#attgrid");

var dataArea = gridElement.find(".k-grid-content");

var newHeight = gridElement.parent().innerHeight() - 2;

var diff = gridElement.innerHeight() - dataArea.innerHeight();

gridElement.height(newHeight);

dataArea.height(newHeight - diff);

}

</script>

It is working up to the point where the window opens, but I cannot click on the child grid to return values to the parent grid.

The columns on the parent grid are read only. How do I update them in javascript?

Edit/Delete buttons in toolbar, not at each row

Having the edit/delete buttons at each row is very space inefficient. I would like to be able to:

Be able to select a row.
Click the Edit or Delete buttons which are at the top (or bottom) of the grid next to the Add New button.
Have check boxes at each row so I can multi-select and delete more than one row at a time.

Does anyone have sample code showing this working before I have to dig in an re-invent this wheel myself?

Thanks,

Brad

_Layout.cshtml modifications

Is there any documentation for the logic how the update wizard modifies the _Layout.cshtml?

After the update the file is always messed up and needs to be reverted. If I can consider some logic from your side it would take a pain away :-)

Grouped Local Data (multiple lines)

I'm having some issues showing multiple lines on the same grid. My objective is a date range in the X axis, a Percentage value in the Y axis and each line to represent a company.

I put breakpoints on the datasource read and I can see that the data is being populated, but after it returns the JSON to the view, no data shows.

Model:

public class CompanyMargin
{
public DateTime? ClosingDate { get; set; }
public decimal? Margin { get; set; }
public string Company { get; set; }
}

Controller: (I have tried 2 ways.. passing directly from the controller itself as a list, and also creating a datasourcerequest action)

public ActionResult MarginsAll()
{
List<CompanyMargin> lstCompanyMargin = new List<CompanyMargin>();
var items = db.spGroupedMargin().ToList();
foreach (var _item in items)
{
CompanyMargin companyMargin = new CompanyMargin();
companyMargin.ClosingDate = _item.InvoiceDate;
companyMargin.Company = _item.Client;
companyMargin.Margin = _item.Margin;
lstCompanyMargin.Add(companyMargin);
}
return View(lstCompanyMargin);
}

[HttpPost]
public ActionResult _GroupedMargin([DataSourceRequest]DataSourceRequest request)
{
List<CompanyMargin> lstCompanyMargin = new List<CompanyMargin>();
var items = db.spGroupedMargin().ToList();
foreach (var _item in items)
{
CompanyMargin companyMargin = new CompanyMargin();
companyMargin.ClosingDate = _item.InvoiceDate;
companyMargin.Company = _item.Client;
companyMargin.Margin = _item.Margin;
lstCompanyMargin.Add(companyMargin);
}
DataSourceResult result = lstCompanyMargin.ToDataSourceResult(request, c => new CompanyMargin
{
Company = c.Company,
Margin = c.Margin,
ClosingDate = c.ClosingDate
});
return Json(result);
}

View:

@(Html.Kendo().Chart<CDashboard.Models.CompanyMargin>()
.Name("MarginChart")
.Title("Company Margins")
.DataSource(datasource => datasource
.Read(read => read.Action("_GroupedMargin", "DashCharts"))
.Group(group => group.Add(model => model.Company))
.Sort(sort => sort.Add(model => model.ClosingDate).Ascending())
)
.Series(series =>
{
series.Line(model => model.Margin, categoryExpression: model => model.ClosingDate)
.Name("#- group.value #");
})
.Legend(legend => legend
.Position(ChartLegendPosition.Bottom)
)
.ValueAxis(axis => axis.Numeric()
.Labels( labels => labels
.Format("{0}%")
.Skip(2)
)
)
.CategoryAxis(axis => axis
.Date()
.BaseUnit(ChartAxisBaseUnit.Days)
)

)

When the page loads, I show a blank chart, then the breakpoint on the _GroupedMargin action triggers. I step through that and I can see that it is indeed populated with data. But as soon as it passes back to the view, nothing shows.

I would also like to question why I cannot find the kendo documentation solution on my local machine. While I had the trial I could open the Kendo.mvc.examples project to get a better understanding of the code. But it seems like once we purchased the product and installed the control panel, the local solution went away. The documentation online is very helpful, but when it offers to show the controller it just shows the generic controller and not the read actions or the models that I would need to see. Please help!

Deserialisation issues for MVC ComboBox Server Control

Hello,

I have been unable to solve this issue for the past 2 days and now need some help.

I am using an Ajax request, to load a partial view, containing two kendo server components bound to my model.

The JavaScript:

01.$.ajax({

02. type: 'POST',

03. url: '/JobEnquiry/GetData',

04. data: {

05. periodNo: selectedPNo

06. },

07. beforeSend: function () { /*alert("before send");*/ },

08. success: function (data) {

09. $("#JobEnquiryContentArea").html(data);

10. $("#JobEnquiryContentArea").show();

11. },

12. error: function (jqXHR, textStatus, errorThrown) {

13. //$('#mnuNav').html(jqXHR.responseText);

14. LSViewer.ShowErrorDialog(jqXHR.status, jqXHR.statusText, jqXHR.responseText, errorThrown);

15. },

16. complete: function () { /*alert("complete");*/ }

17.});

The Model:


01.public class JobEnquiryDetailsModel
02.{
03.    public IEnumerable<JobListModel> JobList { get; set; }
04.    public string Message { get; set; }
05.    public string Branch { get; set; }
06.    public IEnumerable<SelectListItem> jobSelection { get; set; }
07.    [DisplayName("Period")]
08.    public string selectedPeriod { get; set; }
09.    [DisplayName("Job No")]
10.    public string selectedJob { get; set; }
11. 
12.}

and for completion The JobListModel:


01.public class JobListModel
02.{
03.    public string JobNumber { get; set; }
04.    public string ClientReference { get; set; }
05.    public string JobName { get; set; }
06.    public DateTime Opened { get; set; }
07.    public string ProjectManager { get; set; }
08.    public string JobType { get; set; }
09.    public decimal OriginalValue { get; set; }
10.    public decimal BudgetCosts { get; set; }
11.    public decimal BudgetProfit { get; set; }
12.    public decimal ContractValue { get; set; }
13.    public decimal ForecastValue { get; set; }
14.    public decimal CostToComplete { get; set; }
15.    public string WorkOrder { get; set; }
16.    public string Branch { get; set; }
17.    public string ClosedFlag { get; set; }
18.    public string CreatedUser { get; set; }
19.    public string SiteCode { get; set; }
20.    public string ClientName { get; set; }
21.    public string ClientCode { get; set; }
22.}

The Controller method:


01.[HttpPost]
02.public ActionResult GetData(string periodNo)
03.{
04.    JobEnquiryDetailsModel myModel = new JobEnquiryDetailsModel();
05.    DownloadJobData(periodNo);
06.    List<JobListModel> jobsList = MapJobJistData();
07. 
08.    myModel.Branch = "";
09.    myModel.JobList = jobsList;
10.    myModel.Message = "I Fetched some data....";
11.    myModel.selectedJob = "";
12.    myModel.selectedPeriod = periodNo;
13.    PartialViewResult mr;
14.    return PartialView("_JobEnquiryDetails",myModel);
15.}

And lastly my partial View:


01.@model Models.JobEnquiryDetailsModel
02. 
03.<div id="displayParameters" class="row clearfix">
04.    <div class="col-lg-3">
05.        @(Html.LabelFor(model => model.Branch))
06.        @(Html.Kendo().TextBoxFor(model => model.Branch)
07.            .HtmlAttributes(new { style = "width: 80px;" })
08.        )
09.    </div>
10.    <div class="col-lg-3">
11.    @(Html.LabelFor(model => model.selectedJob))
12.    @(Html.Kendo().ComboBoxFor(model => model.selectedJob)
13.                .DataTextField("JobNumber")
14.                .DataValueField("JobNumber")
15.                .BindTo(Model.JobList)
16.                .HtmlAttributes(new { style = "width: 120px;" })
17.    )
18.    </div>
19.    <div class="col-lg-6">
20.    </div>
21.</div>
22.<div id="enquiryContent" class="row clearfix">
23.    <div class="col-lg-5 pull-left">
24.        LEFT HAND SIDE
25.    </div>
26.    <div class="col-lg-7 pull-right">
27.        RIGHT HAND SIDE
28.    </div>
29.</div>

K. Now all that is in, the error is:


1.System.InvalidOperationException: Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

I have read numerous pieces of help on JsonSerialisers, however after trying, none are helping in my particular case.

I suspect it is because I am returning a partial view which is not json, then the kendo server object is doing something under the hood to the model data and boom.

The List I am Binding to is only 17000 odd items, which while large isn't obscene.

Really running out of ideas.

Any assistance appreciated.
