I have a selectable grid (only one row can be selected). When an item is selected, it is bound to a form for editing. Textbox in the form has a custom binding 'valueInput'. If I select a several different items from a grid and then try to edit current selection in the form, all previosuly selected items are modified. If I change binding to built-in 'value' then it works fine (only last selected item gets modified). How to fix it ?

How get the incorrect behavior:

1. Select an element from grid.

2. Select another element from grid.

3. Modify textbox value.

4. All previously selected items will change.

Inside ViewModel , a property is declared:

Hi, I have a problem on Kendo Grid with a field that has a lot of text to show in a column only, so I thought to show it as row, as it's displayed in attached image.
The problem, is that when grouping any column, it doesn't work correctly, it's displayed in the following example.
Is there any workaround or feature about that?

Hi , i am new to KendoGrid and have few questions . could you please provide your valuable input on this as i am not able to find the correct solution for below.

#1 - I am aware of custom validation , but is it possible to attach on-fly pattern check while editing  the cell value , if the value doesn't match with pattern the value should be discarded automatically  similar to inbuilt numeric check when we define type=numeric and try to provide character. 

#2 - i need some conversion while editing , such as lowercase to uppercase OR expand abbreviation such as 1k to 1000 ( k stand for 1000) . where i need to place this logic . Editor or Edit event ?

Hi,

I run the demo from https://demos.telerik.com/aspnet-mvc/grid/editing-popup and having error: System.ArgumentException: 'Value cannot be null or empty.
Parameter name: name. It was during the first initial (controller not hit). MVC 5 application.

If I change GridEditMode.PopUp to GridEditMode.InCell or InLine then Grid works fine. Is it some setup problem? Is there any scripnt needs to be included in bundle in case of GridEditMode.PopUp?

Here is the Grid code:

@(Html.Kendo().Grid<OnTargetInv.Models.EmailAddress>()
.Name("GridEmails")
.Columns(columns =>
{
columns.Bound(p => p.Email);
columns.Bound(p => p.EmailAddressID).Width(140).Hidden();
//columns.Bound(p => p.InactiveDate).Width(140);
columns.Command(command => command.Destroy()).Width(150);
})
.ToolBar(toolbar => toolbar.Create())
.Editable(editable => editable.Mode(GridEditMode.PopUp))
.Pageable()
.Sortable()
.Scrollable()
.HtmlAttributes(new { style = "height:550px;" })
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Events(events => events.Error("error_handler"))
.Model(model => model.Id(p => p.EmailAddressID))
.Create(update => update.Action("EditingPopup_Create", "Client"))
.Read(read => read.Action("EditingPopup_Read", "Client"))
.Update(update => update.Action("EditingPopup_Update", "Client"))
.Destroy(update => update.Action("EditingPopup_Destroy", "Client"))
)
)

Thanks.

Hello,

I am using a kendo UI dropdownlist bound using remote data. I have followed the example using the no data template to add a new item using the text entered on search. However, I am now wondering if it is possible to customise the no data template so that when adding a new item it's possible to capture more information that just the item value i.e. the text from search fields. I would be aiming to display a few text fields and use these to insert data on the back end. I tried adding them however the text fields seem to be disabled and I'm not sure where I've gone wrong or if it's possible?

Many thanks
