CHart with FreeformPointLineSeries gets "frozen" under certain circumstances
Posted: Thu Nov 07, 2019 6:31 pm
Hello, I am using FreeFormPointLineSeries, and I have couple of Lines inside it... Next to Chart, there is also a WPF DataGrid, with Items ... the Items within the DataGrid correspond to the Lines (# of lines = # of items) ... and when I select a Row in the DataGrid, I set the color of the Line, with the LineStyle.Color property. There is a possibility of a Multiselection in the DataGrid ... It works fine, but, if some conditions are fullfilled at the same time, the Chart get's into some weird state, in which it does not "redesign itself" automatically, moving with Mouse over it is necessary.
Those conditions are:
1. there is at least 26 items in the DataGrid AND
2. Virtualization is turned OFF for the DataGrid AND
3. Items in the DataGrid are selected with "CTRL + A"
If at least one of those conditions is FALSE, then everything works fine:
1. there is at most 25 items in the DataGrid OR
2. Virtualiuzation is turned ON for the DataGrid OR
3. Items in the DataGrid are selected CTRL+MOUSE, or SHIFT + MOUSE...
Do you have any idea, why this happens?
