Thanks Matt, I've seen that post before and others like it trying to solve roughly the same problem, and it really doesn't really help.

Your example shows how to change a style in response to mouse enter. This is not even close to my requirement. I have data points set from view models. I need to set the style programatically, whether it be mvvm or any other way.

I'm having to use code-behind already, just to use a dynamic number of series. I don't mind continuing like that, if I can only find a solution.

I also tried a data trigger in the implicit rectangle style, but you are not passing the data item through.

Highlighting data is the most simple and fundamental requirement in a chart. It's a shame if it's not possible.

thanks

Pete

HI,

 You can create a style targeting the Rectangle and wire up the PreviewMouseLeftDownbutton.

 The rectangle DataContext will have the data you.

 You can change the opacity and probably set up a binding to the class(object) each column represents.

Matt,

Check your code. 

DataContext dc = r.DataContext as Infragistics.Controls.Charts.DataContext;
WeeklyTotals wt = dc.Item as WeeklyTotals;

wt is always null, because you are not passing the data item through. I can't tell what data context you mean, your sentence is unfinished, but there is no route through there back to any of my classes to bind to. The rectangle data context does not have the data we need. 

If you can just show me how to 'probably' bind the rectangles, or the columns, to classes that represent them (including multiple series scenarios) then we will be home and dry. Then we can select / multiselect bars in a chart, and we'll be happy. I can do this in the code, and in single series, just can't show which bars are selected to the user in multiple series scenarios.

It's been a week now, and we still don't have a resolution, so we're probably going to have to decide against using your bar chart. Let's hope we don't find similar shortcomings in your other chart types. I'm looking at line charts next, and I think i have examples on selecting values there. It's a shame, because we have nine or so annual licences with you over various technologies. We would have ideally hoped for a path forward on this project that includes Infragistics.

HI,

We should submit a feature request for this issue.

 I have another solution that will work as long as the columns of the chart are not scrolled in an out of view.

 I making use of the Rectangle Loaded event. As each chart is loaded, I put an index number in the tag property.

 Here is my sample.

Matt,

thanks for your continued support. 

We've found a temporary solution by altering the code in the ColumnSeries to popupate the data context with our data item, and then just using a binding in the implicit Rectangle style.  I think you're right that we should submit a feature request, as we don't benefit from your unit tests or quality assurance if we change the code ourselves.

At least we can continue with our implementation.

Thanks

Pete
