Tooltip does not show on condition case

[xyrintech]

I am using the latest Angular5 version and and latest ng-bootstrap version.
I am trying to show tooltip conditionally

<input type="text" id="name" class="form-control" [ngbTooltip]="tipContent" placement="bottom" name="name" formControlName="name">
<ng-template *ngIf="true === true" #tipContent>Hello</ng-template>

But this does not show up. Seems to have some issue.

Not sure what you mean by "show tooltip conditionally" but what you are trying to do is definitively not the way to go... What conditions should trigger tooltip showing / hiding? Maybe you should have a look at the manual triggers on our demo page? https://ng-bootstrap.github.io/#/components/tooltip/examples

Think of condition like form validation.
Now lets say if we need to enable tool tip if form element is not valid.

I have reviewed the examples. I think this case is not specified in those examples.

Please suggest if you need aby further details in order to understand

This is a valid use-case but I believe that this is already covered by the basic building blocks we've got in place. What you would have to do is to create a very simple directive that would:

• inject a NgForm instance and NgbTooltip instance
• subscribe to form control's validity change observable
• on each control's validity change you would have to open / close tooltip conditionally.

What I'm describing here can be seen in action in this plunker:

The bottom line is that ng-bootstrap tooltips can be injected and used programatically. This is a proper way to go about form validation and tooltips.

Now, even if all what I'm describing here works and you can use this approach today, I think that we can simplify it further and make it even easier on users. I'm going to keep this issue open as a feature request, so we can improve integration with form validation. In any case you should not be blocked here any more.
