<kendo-signature name="signature"
maximizable="false"
hide-line="true">
</kendo-signature>
Functionality and Features
Events
You can subscribe to all Signature events. For a complete example on Signature events, refer to the demo on handling Signature events.
The following example demonstrates how to subscribe to events by a handler name.
@(Html.Kendo().Signature()
.Name("signature")
.Events(e => e
.Open("signature_open")
.Close("signature_close")
.Change("signature_change")
)
)
<kendo-signature name="signature"
on-open="signature_open"
on-close="signature_close"
on-change="signature_change"/>
function signature_open() {
// Handle the open event.
}
function signature_close() {
// Handle the close event.
}
function signature_change() {
// Handle the change event.
}
Handling by Template Delegate
The following example demonstrates how to subscribe to events by a template delegate.
@(Html.Kendo().Signature()
.Name("signature")
.Events(e => e
.Open(@<text>
function() {
// Handle the open event inline.
}
</text>)
.Change(@<text>
function() {
// Handle the change event inline.
}
</text>)
)
)
<kendo-signature name="signature"
on-open='function(e)
{
// Handle the open event inline.
}'
on-change='function(e)
{
// Handle the change event inline.
}'/>
Referencing Existing Instances
To reference an existing Telerik UI Signature for ASP.NET Core instance, use the jQuery.data() method. Once a reference is established, use the Signature client-side API to control its behavior.
// Place the following after your Telerik UI Signature for ASP.NET Core declaration.
<script>
$(function() {
// The Name() of the Signature is used to get its client-side instance.
var signature = $("#signature").data("kendoSignature");
//Use the "value" API method to get the Signature's value.
console.log(signature.value());
});
</script>
