Expose EnabledField for the TreeView items

Hi.

I'd like to request the ability to set the Enabled property on check boxes in the treeview.

For example, given a tree view with check boxes:

<TelerikTreeView Data="@StorageItems"
                 @bind-CheckedItems="@CheckedItems"
                 CheckBoxMode="TreeViewCheckBoxMode.Multiple"
                 CheckParents="true"
                 CheckChildren="true" />

I'd like to make the tree view read-only so the check boxes appear disabled and the user cannot check-mark or uncheck-mark them.

Thank you.

Hi NovaStor team,

Thank you for providing details on your desired scenario!

By the time EnabledField parameter is available for the TreeView items, you can use some custom CSS to disable the pointer events of the CheckBoxes. Thus, the users will not be able to check/uncheck them. See the example provided in this public post.

For our scenario, we would initially provide values for the checkboxes of all TreeView items and not allow the user to check/uncheck any of them, having the whole TreeView read-only.

Thank you.

Hi NovaStor team,

Thank you for your confirmation!

I have tweaked the title a bit to denote that the request is for EnabledField of the whole TreeView item. I also updated the thread status to "Unplanned" which indicates this is a valid feature request, not scheduled for implementation yet. As you are creator of the post, you are automatically subscribed and will receive emails on status changes.

In terms of implementing this feature on our side, it will be useful if you can provide some details on the desired use case and how would you expect that feature to behave.

For example, if a child item is marked as disabled(read only), what would you expect to happen if the user checks the parent - shall the child also get checked along with the other enabled children or not? Or your desired scenario is to initially provide values for the checkboxes of all TreeView items and not allow the user to check/uncheck any of them, having the whole TreeView read only?

Thank you in advance! I will be looking forward to receiving your response!

Yes, the option do disable the entire tree view would be good option.

Thank you.

Hello NovaStor team,

One option could be to implement an EnabledField for the entire item that will also disable the checkbox.

Would that be a good fit for your scenario? Please consider and let me know your thoughts.
