It is impossible to set TooltipHintDataMember using the Chart Designer

created 9 years ago

I am trying to use the point2d series chart in devexpress 15.1.8 to display a scatterplot with X,Y values and a point label.
I am able to use the ColorDataMember property fine setting it to the name of a column in the dataset.

However when I set ToolTipHintDataMember to be Name I get the error:
Object of type Charts.Devexpress.Designer.Native.DataMemberInfo cannot be converted to type System.String.

please let me know how to fix this so I can use a string as a ToolTipHintDataMember.

My chart is bound to a DataTable so I want to set the ToolTipHintDataMember to be the column that has the tooltip text, in this case that column is called Name.

Thanks

          I am going to try rebuilding the DLL from source, can you tell me what lines of code changed between 15.1.8 and 15.1.10
          that fix this issue with the chart designer?

          Thanks

            Can I use the chart designer dll from a newer version of devexpress such as 15.1.11 with all other dlls remaining as 15.1.8 or are there breaking changes?

              Hi Christopher,

              Although there is no capability to use different minor versions of DevExpress assemblies (v15.1.8 and v15.1.11) in the same application, you can manually change line #181 in the "DevExpress.Charts.Designer/ViewModel/PropertyGridModel/SeriesPropertyGridModel.cs" source file:

              Before:

              C#
              SetProperty("ToolTipHintDataMember", new DataMemberInfo(value, value));

              After:

              C#
              SetProperty("ToolTipHintDataMember", value);
