Checkbox on treeview

[Elena Popova]

Hi,

I have a treeView and I use the checkbox functionality. I have isChecked="IsChecked" in the treeView and the checkboxes show but I want them to be disabled, meaning you cannot check and uncheck them but still show based on the property. Can you, please tell me how to achieve that.

Thank you!

Elena

Hi Elena, 

Thank you for contacting Syncfusion support. 

You can disable the checkbox element alone instead of disabling the whole node. You need to include the class e-checkbox-disabled into the checkbox element using the drawNode event, 

function drawNode(args) { 

    let ele: HTMLElement = args.node.querySelector('.e-checkbox-wrapper'); 

    ele.classList.add('e-checkbox-disabled'); 

} 

Sample: http://www.syncfusion.com/downloads/support/forum/143301/ze/TREEVI~11969729375.zip 

 

Note: In the above sample, we have disabled all the checkboxes. If you want to disable a checkbox in a particular node, you can get the node id (args.node.id) from the drawNode event and set your condition to skip the other nodes. 

Please let us know if you need further assistance on this. 

Thanks, 

Christo
