Html checkbox data binding

Hello support …

We have tried to build a html template including a checkbox control , we also tried to add an inline expression in html via XML data source binding to control checkbox checked or unchecked outlooks …

HTML sample code will be:

<input name="FD1012" type="checkbox" checked="{{chk02}}" disabled="disabled"/>

XML data source:


It will be OK for checkbox to set checked …

We also try to change XML as:


It still displays checkbox with checked and does not display checkbox with unchecked …

Based on above testing results , I need your help to suggest a good way for us to add an inline expression for checkbox ( checked and unchecked ) via databinding …

thanks !!

We will add in version 22.11.0 the ability to add an inline expression for checkbox ( checked and unchecked ) via databinding.


To set the “Input” element to the checked state, you need to add the “checked” attribute.
This can be done by adding an attribute to the template without assigning values to it, for example:

var htmlCode = "<input name=\"FD1012\" type=\"checkbox\" {{chkAttr}} disabled=\"disabled\"/>";

This functionality will be available from version 22.11, in version 22.10 this example will not work.

Then set the attribute to checked state:

var dataSource = "<Data>\n  <chkAttr>checked</chkAttr>\n</Data>";

To unckecked the “Input” element, you must remove the “checked” attribute.
This can be done with the help of such data:

var dataSource = "<Data>\n  <chkAttr></chkAttr>\n</Data>";

Hello …

How can I download version 22.11 ?

thanks !!
