I Use the Syncfusion GanttControl in wpf on a mvvm architekture.
I bind a observeablelist of tasks to the control. then the magic starts ... the taskname column starting to expanse the width depending on the numbers of entrys in the obserablelist.
Could find any solution to this problem at this time without destroying my mvvm architekture, like forcing my viewmodel to directly interact with the xaml ... this sucks.
