When the Tooltip TargetSelector is button[title] and you change the Calendar's view mode, the Tooltip text remains the initial one. Steps to reproduce:

https://blazorrepl.telerik.com/cIvORFuC16Zgi9yP55

1. Hover over the view navigation button. The Tooltip text is Choose a month, which is correct.
2. Change the view.

Now the navigation button text is 2024 and the Tooltip should display Choose an year, but instead, it displays Choose a month. If you change the view again the button text is 2020-2029 and the Tooltip text remains Choose a month, when it should display Choose a decade.

===ADMIN EDIT===

In the meantime, the workaround is to keep using one Tooltip for the whole application and have another one that targets only the navigation button in the Calendar. Here is an example: https://blazorrepl.telerik.com/GobanlEC46JfsnNk08 

Team,

Currently I am using Telerik UI Blazor with 3.7.0 version, few cases and intermittently TooltipShowEvent.Click is not working and tooltip is not getting displayed and unable to find root cause for it.

Could you please assist what is causing for this behaviour and feasible solution?

Below is sample code snippet where we use 3 tabs

<TelerikTabStrip Class="tmGraphTabStrip" ActiveTabIndex="@ActiveTab" ActiveTabIndexChanged="@ActiveTabChanged" @ref="@TabRef">
@for (var i = 0; i < 4; i++)
 {
<TabStripTab Title="@TabName" Class="tmTabHeaderCellStyle">
<TelerikGridLayout RowSpacing="20px" ColumnSpacing="1px" Class="grid-CardlayoutNew">
@*
display data in gridlayout structure for each row/column along with tooltip, we are able to see div selector and target selector Ids from Dev Tools browser
*@
</TelerikGridLayout>
</TabStripTab>
}
</TelerikTabStrip>

Ex:

<TelerikTooltip TargetSelector="@ToolTipCurselector" ShowOn="@TooltipShowEvent.Click" Position="TooltipPosition.Top">
</TelerikTooltip>

Hi !

After upgrading to the lastest version (6.1.0) we have an issue with the tootip.

The small arrow that points towards the elements that have the title attribute is not showing where it should (the arrow stays centered).

Here is an example:

I'm using the ToolTip component to display tooltips for anything that has a "title":

<TelerikTooltip TargetSelector="[title]"></TelerikTooltip>

I've got a popup window with a close button that displays the tooltip "Close".

Upon clicking the button and the window closing, the tooltip remains until I click something or another tooltip appears.

I need to make a tooltip more accessible.

ADMIN EDIT

The first thing you can do is use the aria-describedby on the tooltip targets and use its value in the tooltip Id parameter to help screen readers. It is up to the screen reader to detect the change in the DOM and read out the new content.

This item is to add attributes to the tooltip such as role="tooltip", aria-live="polite", role="presentation", aria-hidden="false". The exact attributes will depend on more detailed research and may differ from what I have listed here.

---

Unfortunately the tooltip component does only work for elements that are present at first rendering.

If elements are surrounded by an if-condition which becomes true at a later point in time, the tooltip is not displayed.

Our usecase:  We have tables where some data is computed after displaying the rest of the table.  The computing and displaying works and the title is there (and shown in the default windows tooltip) but the Telerik tooltip is not displayed.

How can I set the tooltip to show/hide programmatically? right not it only supports hover or click show action.

ADMIN EDIT

You can Follow a way to hide the tooltip programmatically here: https://feedback.telerik.com/blazor/1476364-close-tooltip-via-method.

You can find a way to hack the show event by triggering a JS click in this KB article: https://docs.telerik.com/blazor-ui/knowledge-base/common-validation-error-in-tooltip.

Here is an example that shows how you can trigger the tooltip to show for a particular target:

@inject IJSRuntime _js

<script suppress-error="BL9992">
    function triggerTooltip(index, selector, showOnClick) {
        var targets = document.querySelectorAll(selector);
        if (targets && targets.length >= index) {
            var desiredTarget = targets[index];//feel free to get the desired target in any other way
            setTimeout(function () {
                var evt = document.createEvent('MouseEvent');
                var evtToSimulate = showOnClick ? "click" : "mouseenter";
                evt.initEvent(evtToSimulate, true, false);
                desiredTarget.dispatchEvent(evt);
            }, 20);
        }
    }
</script>

<TelerikButton OnClick="@( async () => await TriggerTooltip(0) )">Trigger tooltip for the first target</TelerikButton>
<TelerikButton OnClick="@( async () => await TriggerTooltip(1) )">Trigger tooltip for the SECOND target</TelerikButton>

<TelerikTooltip TargetSelector="@ttipTargetSelector" ShowOn="@ShowOnSetting">
</TelerikTooltip>



<p id="my-targets">
    <strong title="what is 'lorem ipsum'?">lorem</strong>
    ipsum dolor
    <strong title="is this a real word?">sit</strong>
    amet.
</p>

@code{
    string ttipTargetSelector = "p#my-targets [title]";
    TooltipShowEvent ShowOnSetting { get; set; } = TooltipShowEvent.Click;
    async Task TriggerTooltip(int targetIndex)
    {
        await _js.InvokeVoidAsync("triggerTooltip", 
                targetIndex, 
                ttipTargetSelector, 
                ShowOnSetting == TooltipShowEvent.Click ? true : false
             );
    }
}

Tooltip does not show if moving from one element with Tooltip to another and both elements are placed directly next to each other.

Example: If a number of Buttons (with title) are placed right next to each other if mouse is moved over the first one the tooltip is displayed correctly. If the mouse is moved to the next one the first tooltip closes but the second one does not show. Moving on to the third button the tooltip is displayed correctly again.

If the element of the tooltip is on top of the screen (almost outside of the viewport), hovering the remaining part of the element makes the tooltip create a flashing effect.

Please watch the attached video. 

When a position is specified the tooltip is rendered initially aside from the target element before displaying at the correct position

I would like to be able to do something like the following - cause the tooltip to close from my code:

<TelerikTooltip TargetSelector="#tooltip1" ShowOn="@TooltipShowEvent.Click" @ref="@TooltipRef">     
            <Template>
                 Content Here
                <button type="button" class="btn btn-primary" @onclick="tipClose">Save</button>                
            </Template>
</TelerikTooltip>

<a href="#" id="tooltip1" class="btn btn-secondary">open</a>

@code{
 Telerik.Blazor.Components.TelerikTooltip TooltipRef { get; set; }

void tipClose()
    {
       // TooltipRef ?
    }


}

Please consider the ToolTip's ability to track changes in its target and update its own position accordingly.

A good example for this is the integration between the ToolTip and the Slider drag handle.

Using a target selector for HTML elements with a specific attribute within an SVG does not work

The following snippet worked correctly in 2.26.0 and older versions but does not work in 2.27.0

<TelerikArcGauge>
    <ArcGaugeCenterLabel>
        <Template>
            @(context.Pointers[0].Value)
        </Template>
    </ArcGaugeCenterLabel>
    <ArcGaugeScales>
        <ArcGaugeScale Min="0" Max="100">
        </ArcGaugeScale>
    </ArcGaugeScales>
    <ArcGaugePointers>
        <ArcGaugePointer Color="#FFE162" Value="@FirstPointerValue"></ArcGaugePointer>
    </ArcGaugePointers>
</TelerikArcGauge>

<TelerikTooltip TargetSelector="path[stroke='#FFE162']" Position="TooltipPosition.Top" ShowOn="@TooltipShowEvent.Hover" Id="first-pointer">
    <Template>
        <p>Value is: @FirstPointerValue</p>
    </Template>
</TelerikTooltip>

@code {
    public int FirstPointerValue { get; set; } = 20;
}

Since 2.27 I have a weird behaviour when I try to open a tooltip that should be shown on click. This is a sample:

<span id="tooltip-here">
    <span style="background-color: gray">Text 1</span>
    gap
    <span style="background-color: gray">Text 2</span>
</span>
<TelerikTooltip TargetSelector="#tooltip-here" ShowOn="TooltipShowEvent.Click" />

In 2.26 the tooltip was shown when I clicked in any element inside the outer span. Check file 226.gif.

Now, in 2.27 it is being shown just when I click on the "gap". Check file 227.gif.


Thanks!

Is there a way to add some delay to the TelerikTooltip component show event? I would like to force the user to hover in the element for a couple of seconds before he can see the tooltip.

Like in the ajax tooltip demo.
