hi,
I am creating a sample chart and I wanted a tooltip to be display on it.

I am using following code for tooltip:

I have X -Axis (DateTime) and Y-Axis (Double) value.
I am using following code for tooltip:
ItemToolTipFormat = XAxisPropertyName +
":#XCAT{d}" + "\r\n" + YAxisPropertyName + ":#Y";
where XAxisPropertyName is the name of the X-Axis and YAxisPropertyName is the name of the Y Axis.
I am using {d} for formatting but still tooltip shows the "1/1/194 12:00:00" for DateTime part... It include the time which I don;t want.
how do i set the tooltip formatting for Datetime and other type like Double where I may want to display number of decimal places.?
Thanks,
Vinod Sa.

Hi Vinod,
The "#XCAT" token already represents a string, so it cannot be further formatted. Still, you can retrieve the date from the underlying object using the "#DATAITEM.<PropertyName>" token (ex. "#DATAITEM.DateReceived{d}". You can find more information here.

Hi Daniel,
RadChart allows you to specify how to format the labels by the ChartArea.LabelFormatBehavior property as described in our help topic. By default it is set to HumanReadable. If you set it to None the numbers will be shown according to your Culture (with two or more delimiters):
NOTE that changing the LabelsFormatBehavior will affect the whole ChartArea (the Axes, the Series, theToltips and etc.)
I hope this helps.
All the best,
Evgenia

Hi Daniel,
Let me start with my apologies for the late reply. As reading carefully your requirement now I realise that you want to set Currency as format for your Tooltips and as well to change the way the values appear (123456 -> 1.234,56).
Since there is no way to set two formats for one and the same value at same time using the ItemTooltipFormat property, what I can suggest is that you handle the ItemTooltipOpening event and set the formats there before applying the content to the tooltip. For more information you can refer to our help topic.

Hi Evgenia,
I really appreciate your help, but I´m new with Telerik controls and I could not apply your suggestion, probably because I don´t have experience with Telerik controls.
In true, I´m a little surprise because aparently is a simple feature to have in charts and is necessary specially configurations to have the expected result.
Thanks, best

Hi Daniel,
Here is how to achieve the desired formatting (123456 -> 1.234,56 $):
Handle the ItemDataBound event of the Chart and set the following format for the tooltips:
Note that by default in American culture the $ sign appears before the number (shown here), the CurrencyDecimalSeparator is "." and the CurrencyGroupSeparator is ",". By making a clone of the culture I'm specifying these properties as I want. If you like you can change the $ sign with whatever CurrencySymbol you like.
I hope this helps.
Kind regards,
Evgenia

Hi Evgenia,
Hope this finds you well.
I´m trying to use your suggestion, but, in this line:
e.DataPoint.Tooltip = e.DataPoint.YValue.ToString("C", format);
I receive this error message:
'Telerik.Charting.ChartItemDataBoundEventArgs' does not contain a definition for 'DataPoint' and no extension method 'DataPoint' accepting a first argument of type 'Telerik.Charting.ChartItemDataBoundEventArgs' could be found (are you missing a using directive or an assembly reference?)
I´m using asp.net ajax. Can this command to apply in this scenario?
Thanks for your help.

Hi Daniel,
Since this thread is related to RadChart for Silverlight, all my posts up to now were for this technology.
To be able to achieve this formatting in RadChart for ASP.NET AJAX you can handle the same event (ItemDataBound) but instead of DataPoint in the eventargs you'll have to use the SeriesItem. Here is how to do this:
Please keep the content of the posts related to the Product of the forum, so that it is easier for both sides to follow it.
