Hi,

I have a form with a MultiSelect displaying 'Exercises'. When the form is submitted the Exercise data is passed to the model as part of the form data (e.g.Exercises:"f86a60ce-04dc-4208-a2b6-a5ee00a1990f")

However when nothing is selected in the list, the 'Exercises' parameter is excluded from the post data. As the Exercise data is not included, the model.Entity.Exercises remains unchanged and contains the original selected values.

Is there any way the Kendo MultiSelect can pass in a null value when posting an empty list, so that the form data includes the Exercise parameter? e.g. Exercises:Null 

Hi I´m using the Kendo.Mvc.dll version 2014.1.318.440, I have some problems adding the action of Export to Excel on my grid, 

Does not recognize the tools.Excel(), it is possible to use this statement with this Kendo version, or am I missing a reference for example a js file needed to bound??

Here's the code of the grid. 

  @(Html.Kendo().Grid<Project.Models.GridModel>()
                    .Name("Grid")
                    .Scrollable()
                    .EnableCustomBinding(true)
                    .HtmlAttributes(new { style = "height:auto;" })
                    .DataSource(dataSource => dataSource
                        .Ajax()
                        .Model(model =>
                        {
                            model.Id(x => x.NumOP);
                        })
                        .ServerOperation(false)
                        .PageSize(20)
                        .Read(read => read.Action("LoadGrid", "GridController"))
                        )

                    .Columns(columns =>
                    {
                        columns.Bound(p => p.Name).Title("Name").Width(80);
                        columns.Bound(p => p.Description).Title("Description").Width(200);
                        columns.Bound(p => p.Amount).Title("Amount").Format("{0:0,0.0}").Width(100);

                    })
                    .ToolBar(tools => tools.Excel())
                    .Excel(excel => excel
                        .FileName("ExcelFile.xlsx")
                        .ProxyURL(@UrlAction("Excel_Export_Save", "CreditosActivos"))
                        )
                    )

Thanks for help

I have a categories dropdown list in the grid that i am populating very similar to the 'Editing custom editor' example. I populate the default categories in the index() method of my controller, just like the example shows and it works fine. When a 'organization dropdownlist' is chosen, I want to repopulate the categories based on what organization was chosen, but when I try to 'Add new record' in the grid, the old categories remain bound to the grid and it doesn't save properly.

I have in my grid something similar to this defined for the default value:

model.Field(p => p.Category).DefaultValue(ViewData["defaultCategory"] as Kendo.Mvc.Examples.Models.CategoryViewModel);

Every time a new organization dropdown item is chosen, and a read operation occurs, how would I update or rebind the model to reflect the new defaultCategory?

Thanks in advance,

Dave

The official 2016 Q2 Release (2016.2.504) release will export Excel files with grid lines disabled.

The change is not intentional and will be reverted in the following hotfix and service pack releases.

As a workaround you can turn on the grid lines explicitly in the ExcelExport event:

Hello, 

I have a column in my Grid with a custom filter which has pre-populated values in a dropdown. When user opens the page I want the default value to be set to a value that I pass from the Controller in ViewData. I'm able to set the grid filtered to a value on page load but the dropdown in the filter does not have the value selected.

Grid has the below column

 columns.Bound(c => c.DealYear).Filterable(filterable => filterable.UI("yearFilter")).Width(70);

with the below options set

.Filterable(filterable => filterable
        .Extra(false)
        .Operators(operators => operators
           .ForString(str => str.Clear()
               .StartsWith("Starts with")
               .IsEqualTo("Is equal to")
               .IsNotEqualTo("Is not equal to")
           ))
        )

And on page load I filter the grid with a value passed from Controller  - This works fine.

  .Filter(f =>f.Add(p => p.DealYear).Equals(ViewData["DealYear"]))

But in my javascript, how do I set the value to the Filter Dropdown?

function yearFilter(element) {
        element.kendoDropDownList({
            dataSource: {
                transport: {
                    read: "@Url.Action("FilterMenuCustomization_DealYear")"
            }
        },
            optionLabel: "--Select Year--"
        });
    }

The page loads with a predefined filter but the dropdown in the Filter shows 'Select Year'.

Thanks!

I'm trying to combine the SignalR live updates example with the Hierarchical grid example.

I want both grids to update via SignalR when there's a change. The Customers grid works great.

Trouble is, I can't even read the  order data when I switch the Order grid to SignalR. The Read method on the child (order) grid is never called.

I wish there were more documentation on the Transport, Promise, and Hub properties.

Any suggestions?

Hi,

We have different cultures setup based on the user login.

We found an issue with grid sort, it seems sorting correctly with US culture, but it fails with UK or custom cultures.

thanks!

I have a grid that includes the Export to Excel functionality.

I retrieve the grid options via getOptions() and store them to local storage so that I may later restore those settings by using setOptions().  The  Export to Excel button is not being displayed after I call setOptions() so I'm assuming this is something I need to manually add to the configuration.  However, I'm having a hard time coming up with the syntax.  How do I do this?

The relevant configuration of the grid looks like this:

Code to populate the grid options looks like this:

I have a Menu that has 9 root level items and many children items under each of them.

I have added tooltips to the items, but I do not want tooltips for the root items to show up at all.

I am loading the text using the ContentHandler and I have tried setting the text for the root items to "" and also to null. I have tried just leaving them out of the JavaScript that I use to set the text.

No matter what I have tried, I get an empty tooltip box showing next to the root item when I first hover over it.

TIA,
Bob Mathis
