Id created a workaround.
I created a resize function for the UltimateGridControl,
which uses my (for example)"COL_1_WIDTH = 20""COL_2_WIDTH = 30" defines
and resizes all cols of the Grid without manipulating the data.
It works cause the UGC-defines are relative to the whole grid control.
Its not the best solution,cause im just supressing and overpainting,
but for the moment the best working.
Thank you for your help
___i can fire it in the
::OnSize(UINT nType, int cx, int cy)
CDialog::OnSize(nType, cx, cy);
UPDATE_EASYSIZE;
if(GridCtrl)
GridCtrl.ResizeColsWidth();
here i use a for loop to set all the WIDTH_DEFINES for setting the width again, without updating the data.
