UltraChart Gantt chart add custom tooltip information
posted

Hi All,

I would like to add the custom tooltip in my Gantt chart.

I did not find any source to bind.

I have one more column [description] in datatable and want to display that data as tooltip in each bar.

How to bind the data when grid bind.

Thank.

    Hi,

    Thank you for posting in our forums.

    What you could do in your case is to use the IRenderLabel interface. It allows you to customize the strings for the axis labels, the tooltips, etc. You need to implement only one method – ToString – for this interface, which has an argument, containing the information for the data source row among other things. Using the argument you can get the value from the data table and return it as the tooltip. For more information on this interface, please visit this link:

    http://help.infragistics.com/Doc/WinForms/2014.2/CLR4.0/?page=Chart_Customize_Labels_Using_the_IRenderLabel_Interface.html

    I have attached a sample that demonstrates this suggestion.

    Please let me know if you have any additional questions.
