Hello,
I am currently using the textbox UI component for my webapp and i'm utilizing the floating label and I'm very pleased with the outcome. I came across many situations where I need a text field that would benefit from multi line capabilities.
it seems like there are currently no UI components at this time that allow multi-line capabilities. Are there any solutions at all, at this time, that will allow me to use a text field with multi-line??
Thanks,
I am trying to load a partial view inside of one of the splitter panes. I have done this previously using the HTML helpers in an old project, but I am having troubles replicating this with Tag Helpers.
If I use content-url, I get the page inside of an iframe, which doesn't have my styles applied and the iframe only takes up a small amount of the pane with overflow scrollers. The HTML Helper in the old project loaded the returned html in the pane.
How can I load the partial view using ajax with the tag helpers?
How do you configure the treeview to accept unstructured but properly formed json?
It must be possible because Chrome Development Tools has no problems showing any json sent to it.
I'm trying to implement an upload into a window.
this is a code
<!-- >> IMPORT EXCEL-->

.Height(300)

.Validation(v=>v.AllowedExtensions(new string[] { ".xlsx", ".xls" }))
.Async(a => a
.Save("Async_Save", "UploadContacts")
.Remove("Async_Remove", "UploadContacts")
.AutoUpload(true)
).Events(e=>e.Error("uploadError"))
)
}
</
text

.Visible(false)
.Render();
}
function uploadError(e) {
alert(e.XMLHttpRequest.response);
}
[...]

when I open the window and I try to upload a file, I obtain this effect (attached screen-shots)
The strange thing is that if I set a breakpoint into actions, I notice that it doesn't go into an action AsynchSave.
I create App_Data folder into wwwroot node's project (is it corrects?
Where I wrong?
Is there a place where I can see all of the tool names for the Tag Helpers?
I can't seem to get the TableEditing or the SuperScript tool too show. They both just say "undefined".
Hi,
I am experiencing an odd behavior when using the .NoRecords() function of the grid. If I add .NoRecords() the height of the grid auto sizes to an extreme height beyond the view screen height when there are no records. If there are records, then the grid auto sizes appropriately. If I remove .NoRecords() then the grid is collapsed to a reasonable height when no records are available. I have not had this issue with previous versions. Using Developer Tools for the browsers I cannot see any .css file that is applying any height value that would be causing this issue. Is this a known issue, working as intended or am I missing something?
I am using version 2020.2.513.
Thanks.

How do I refer to a model property value in the template? I have:
<
div
class
=
"k-content"
>
@(Html.Kendo().ListView<
MemberSkillModel
>()
.Name("listViewSkills")
.TagName("div")
.ClientTemplateId("skillstemplate")
.BindTo(@Model.MemberSkills)
)
</
div
>
and
<
script
type
=
"text/x-kendo-tmpl"
id
=
"skillstemplate"
>
<
div
class
=
"k-widget"
style
=
"border:0px"
>
<
div
class
=
"row"
>
<
div
class
=
"col-12"
>
#:Name#
@if (@Model.MemberSkills.ExpiryDate != null)
{
@:(exp kendo.toString(ExpiryDate, "MMMM dd, yyyy")#)
}
</
div
>
</
div
>
</
div
>
</
script

Obviously @Model.MemberSkills.ExpiryDate throws an error as it needs a model item instead of the entire model contents.
Hi, My kendo inline grid is not calling the update method in controller, when any of its fields is autopopulated dynamically.
I am not manually editing any of the fields in the particular row, instead the fields are getting automatically populated. And on update click I need to do validation in server controller method .But unfortunately the control is not going to the server method on update button click.
Can someone help me to resolve this,
Hello,
I'm using ASP.NET Core 2.1 and trying to get a Pie chart bound to a remote datasource based on this example: https://demos.telerik.com/aspnet-core/pie-charts/remote-data-binding. I can't get anything except the "Title" to show. The pie never displays. (FYI, the pie chart works fine for hardcoded data.) I know the controller works as I'm getting response data in the format I expect. Here's some streamlined code:
Here's my view:
@(Html.Kendo().Chart<WT.Models.Cars>()
.Name("chart1")
.Title(title => title.Text("Title").Position(ChartTitlePosition.Top))
.DataSource(ds => ds.Read("CarTotals_PieChart", "Output"))
.Series(series => series.Pie(model => model.NumCars, model => model.CarManu))
)
Here's my model:
public class Cars
{
public string CarManu{ get; set; }
public int NumCars { get; set; }
}
Here's my response JSON data:
{"Data":[{"CarManu":"GM","NumCars":167},{"CarManu":"Ford","NumCars":120},{"CarManu":"Mazda","NumCars":60},{"CarManu":"Ferrari","NumCars":19}],"Total":4,"AggregateResults":null,"Errors":null}
I've seen other posts related to this exact same (issue but never a resolution. What am I doing wrong? Thanks in advance.
