I am using Master-Details view and have toolbar buttons for expanding/collapsing all rows in addition to a button to clear all grouping levels. Unfortunately after expanding details either via buttons or the grid, the row headers of the rows that were expanded grow very large in height. I have tried using the following in the button_click handler but the header rows remain large...
sf_sop_grid.GetVisualContainer().RowHeightManager.Reset()
sf_sop_grid.GetVisualContainer().InvalidateMeasureInfo()
