Image size in Editor in % not in px size

Hi,

When adding a large image (>1000px width) in the Editor, it looks fine on a laptop/tablet.

But when showing it on a mobile, it doesn't.

Is it possible to enter the image size in % so it auto rescales depending on the screen size?
Or is there another way to solve this problem?

Thanks...

Remove buttons from Editor Toolbar when showing on mobile

Hi,

I'm using the Editor with a lot of options/buttons and that works fine on a 'large' screen.

On a mobile it will split over 4 lines.
(Hardly no room for editing text left)

Is it possible to reduce the number of options/buttons in the toolbar when showing it on a mobile phone?
(I only want to keep the Bold/Italic/Underline buttons)

Thanks....

                    toolbar.Create();
                    toolbar.Excel();
                    toolbar.Search();
                })

                .Excel(excel=>excel.ProxyURL(Url.Action("Excel_Export_Save", "Grid")))
                .Editable())

And last point is I would like to have it works also when user add or change value

Is there possibility to update Sum when cell change?

Many thx in advance

Confused about ASP .Net Core and its use with Angular for frontend

Hi,

I'm pretty new to ASP .Net Core but I have read on microsoft site that code written with it can be run on the browswer and can be used to create UI. So, If all this can be done with ASP .Net Core why is people pairing it with Angular? I known there's something I'm missing here but don't know what.

I would really appreciate it if anyone could clarify it.

Cheers!

Set "maxlength" to a field in forms

Hi,

I'm trying to set the maximum length of input characters using HtmlAttributes in a form. But it seems it doesn't work; I can still type more than 4 characters. Here is an example in REPL:

https://netcorerepl.telerik.com/wmkmbflo51nxiZPb01

                   i.Add()
                        .Field(f => f.FirstName)
                        .Editor(e=> e.TextBox().HtmlAttributes(new { maxlength = "4" }))
                        .Label(l => l.Text("First Name:"));

Thanks,

Humberto

No records to display even when I can see data in Network Monitor

I'm using the MVC extensions to setup my Tree List

@(Html.Kendo().TreeList<SiteMapTreeModel>()

.Name("treelist")

.Columns(columns =>

{

columns.Add().Field(c => c.Title).Title("Title").Width(250);

columns.Add().Field(c => c.Url).Title("URL");

})

.DataSource(dataSource => dataSource

.Read(read => read.Action("SiteMapTree", "HomeAjax").Data("getServiceAndLocale"))

.Model(model =>

{

model.Id(m => m.Id);

model.ParentId(m => m.ParentId);

model.Field(m => m.Title);

model.Field(m => m.Url);

})

)

.AutoBind(false)

.Selectable(true)

.Deferred()

.Height(540))

... and using Chrome Dev Tools > Network, I see the following data in the AJAX method SiteMapTree, but the Tree List says "No records to display":

{"Data":[{"Id":1602,"ParentId":1000,"Title":"Dashboard","Url":"~/Dashboard/Start","hasChildren":true},{"Id":22,"ParentId":1000,"Title":"Rules","Url":"~/Rules/Start","hasChildren":true},{"Id":1,"ParentId":1000,"Title":"Administration","Url":"~/Admin/Start","hasChildren":true}],"AggregateResults":{},"Errors":null}

... and I am using ToTreeDataSourceResult() in the AJAX method to format the data (and ParentId of 1000 is the root of the tree).

What am I doing incorrectly?

FYI: I have set the AutoBind of the TreeList to false because I am calling dataSource.read(); when a dropdownlist item is selected. The Tree List has no context until the dropdown is selected.

Thanks,
--John
