RadToolTipService.SetToolTipContent Does not work with none text objects

[M]

I have a stackpanel and in code behind using of RadToolTipService.SetToolTipContent method. When I use a text as second parameter all things are good but using an Object , I have an empty tooltip. RadToolTipService.SetToolTipContent(MyStackPanel,MyObject) hear myobject is a complex stackpanel including textblocks and some nested stackpanel. I found If we set a simple text as the second input we are OK .When we send an object (hear stackpanel) we have an empty tooltip. Is there a bug? or there is a solution for this problem ? -  Telerik version is 2016 r3

Hello M,

I'm not quite sure about your scenario. Could you please send us a code-snippet or a sample project to see your implementation? Are you defining the tooltip and the stackpanel in code-behind or in xaml and code-behind? In your case maybe you need to change the ToolTipTemplate.
 
You can try the following code and see if this works for you: 

<TextBlock Text="TextBlock" x:Name="mytextblock"
    telerik:RadToolTipService.Placement="Bottom"
    telerik:RadToolTipService.VerticalOffset="-10"
    telerik:RadToolTipService.ToolTipContentTemplate="{x:Null}">
    <telerik:RadToolTipService.ToolTipContent>
        <telerik:RadToolTipContentView>
            <StackPanel>
            <TextBlock Text="Content line 1" />
            <TextBlock Text="Content line 2" />
            </StackPanel>
        </telerik:RadToolTipContentView>
    </telerik:RadToolTipService.ToolTipContent>
</TextBlock>

I'm looking forward to your reply.

Hi Milena

At first I thank you for your attention.I have a stackpanel including some objects(hear some radshape).All of these are in xaml .I try set a tooltip to this stackpanel in code behind (related to real time data ...) . In this case I will have a tooltip on the stackpanel with the default time of 5 . I want to exceed this time . I found that some telerik fetures work for setting of a tooltip . If I replace my scenario with  " a stackpanel including a textbox (and a tooltip with none default time for example 15 seconds in code behind)" it works fine and the timing of 15 seconds works fine . If we replace any none textbox object(s) with the text box , we only can see 5 second the tooltip . My code in codebehind is :

ToolTipService.SetToolTip((StackPanel)oItemShape.Parent, oBorder);
ToolTipService.SetPlacement(oItemShape.Parent, System.Windows.Controls.Primitives.PlacementMode.Right);
Telerik.Windows.Controls.RadToolTipService.SetShowDuration((StackPanel)oItemShape.Parent, 10000);

 

note:oItemShape.Parent is the my stackpanel that I want to set a tooltip to it. In this scenario 10000 does not work .

If I replace some objects(radshapes) with one or some textbox , delay timing works fine !

Hello,

I tried to follow your scenario but I'm not quite sure that I understand it. This is why I think that it would be better if you could send us an isolated project where we can take a look at your implementation and provide you with more information.

In addition, I noticed that in the code-snippet you sent you are using MS ToolTip (ToolTipService) and you set the duration of RadToolTip (RadToolTipService). This could be the reason why the duration property is not respected.
