Hi to All,
I would like to select/deselect (multiple) displayed points in a BubbleSeries, preferable with Click then Ctrl+Click. I suppose there will be 3 issues to solve:
Q1: How to catch the click then recognize what point is under the cursor? (what point was clicked)
Q2: How to change the point's appearance (say increase radius, by changing the binded data, any better idea?). Btw: Can I change the shape of an individual point, like from circle to square?
Q3: Maintain what is selected. (in a list.) (does any internal implementation for this?)
Thanks in advance
Thank you for your post. I have been looking into your requirement and in order to get the clicked underlying data item you could handle the ‘SeriesMouseLeftButtonDown’ event of the XamDataChart like:
private void theChart_SeriesMouseLeftButtonDown(object sender, Infragistics.Controls.Charts.DataChartMouseButtonEventArgs e)
BubblePoint dataPoint = e.Item as BubblePoint; // where BubblePoint is the type of your data item
In order to notify that some data point is selected I am changing its color.
I am attaching a sample application(DataChartBubbleSeriesSelection.zip) that shows my approach on how to select multiple items when pressing Ctrl key.
Let me know, if you need any further assistance on this matter.
How can i programatically do it, instead of clicks on ellipse ?
