Does the drop down list tag helper have events?  I can't seem to find documentation anywhere on events.  I want to take action when selected or changed.

<kendo-dropdownlist name="products" filter="FilterType.StartsWith"></kendo-dropdownlist>

 

The examples in the link below only cover the HTML Helper.

Hello,

Is there a way to open the toolbar's splitbutton popup to show the items when the splitbutton itself is clicked instead of the little arrow?

Thanks,

Shawn A.

toolbar.ClientTemplat(string) seems to override all previous toolbar items.

So:

 

.ToolBar(toolbar => {
                        toolbar.Create(); /*toolbar.Save();*/
                        toolbar.Custom().Text("export").IconClass("k-icon k-i-table").HtmlAttributes(new { onclick = "approval_grid_export()" });

                        toolbar.ClientTemplate("etc");

                    })

seems to destroy the toolbar.Create() and toolbar.Custom().

Is there way to just add the ClientTemplate()?

Hello,

Is there a way to position the items in a Kendo Toolbar so that some buttons are located on the left-side of the toolbar and some on the right side with empty space between?

Thanks,

Shawn A.

Hello,

The column filter icons on my grid are interfering with the column header texts.  Sometimes they are right on top of the texts (see attached).  How do I position these icons so that they are on the bottom right corner of the column header and away from the header text?

Thanks,

Shawn A.

I am trying to get a value and use it to change a label.
All the examples I have found in documentation include only the html helper version
I am using the tag helpers and can’t figure out how to do it.
I tried this:

<script>
         
        function onSelect(e) {
            alert(e.item.Text);
        }
    </script>

<kendo-dropdownlist name="DocumentTypes" on-select="onSelect" for="GovIdTypeID" class="jProfileMod" datatextfield="Name" datavaluefield="Id" bind-to="Model.GovIdTypes" cascade-from="CountryID" cascade-from-field="IssuingCountry.Id"></kendo-dropdownlist>

But it is not working.

Hi, Im doing this, but all tools in toolbar are showing? Shouldn't .Clear() do the trick? FYI: Id and body in code below is set from mvc c# variables

@(Html.Kendo().Editor()
                .Name(id)
                .Events(events => events
                    .Keyup(change)
                )
                .Tools(tools => tools.Clear())
                .Value(@<text>
                    @Model.Body
                </text>)
)

I want to show a Kendo window, type something in a textbox in the window, and return the value from to the parent page. How can I do this?

My window definition.

<kendo-window name="InstallerSearch"
              title="Search for Installer"
              draggable="true"
              resizable="true"
              width="1100"
              height="550"
              modal="true"
              visible="false"
              on-close="onClose"
              actions="actions"
              iframe="true">
    <content>
        loading...
    </content>
    <popup-animation enabled="true" />
</kendo-window>

 

JavaScript to open window

function selectInstaller() {
    var window = $("#InstallerSearch").data("kendoWindow");
    window.refresh({
        url: "@Url.Content("/Admin/Installers/Search/")"
    });
    window.open();
    window.center();
}

 

Razor page content for the window

Installer Name<br />
<input name="InstallerName" id="InstallerName" type="text" class="form-control-md" />

 

JavaScript for the close where I want to get the value in the textbox in the window but user input is undefined.

function onClose() {
    var userinput = $("#InstallerName").val();
    alert(userinput);
}
