Hi,

I have a checkbox group, In the initial stage the user should not be able to check it means it should be read only and on some action the user should be able to check them..

How can i do this.

Hi,

try the below process

take one boolean attribute and bind with the checkboxgroup element's enable property.

and initially set it to false.

when required set it to true.

Hi,

Where have you created the attribute binded to the enabled property of checkbox group. Try to create it directly under the Main Context node because currently you might have created it under some node whose object has not been instantiated.

Hi,

where you created the boolean attribute ?

if you created it under the node which populating the checkboxgroup.

then you have to set it as false when you populating the checkboxgroup.

if you trying to make all checkboxes disable and enable ,take the boolean attribute outside to it ie root context.
