Unable to set dateTimeValues in GanttChart after upgrade to version 15.1.8

created 9 years ago

Hello,

after upgrading to 15.1.8 the whole Designer for the XtraChart changed and I am not able to drag DateTime properties to the Value1 and Value2 cells.
In 14.1 it was possible to set Value scale type to DateTime.
I cannot find any options to define this.
How do I create a Gantt chart over TimeDate values?

Kind regards
Eric

    I have found the option for setting the ValueScaleType.
    But are you serious with this procedere?
    You create a Gantt and cannot set the values to DateTime properties because you have to change the ValueScaleType in the properties tab. But you get an error trying to set it to DateTime because there are dummy values which are autocreated and prevent the property from being changed. So you have to navigate to the Points in the menu left side to delete every single autocreated Point.
    After that you can set the ValueScaleType to DateTime and than you can set the value property.
    This is really bad handling for the user so maybe it would be a good idea to change the ValueScaleType automatically when a value property is set.
    Also it seems there is a skin problem after dragging the properties.
    It results in white forecolor on white backcolor with Visual Studio Dark Style (lower right side in the attachement).

    Kind regards
    Eric
