I can't find any function that can help me with this and I don't want to write crazy function that will HitTest every pixel of ListView area, to find out coords of needed Column (if it ever possible to get Column from HitTest).
Thanks to Yair Nevet comment, I wrote next function to determine Left position of needed Column:
private int GetLeftOfColumn(ColumnHeader column, ListView lv)
{
if (!lv.Columns.Contains(column))
return -1;
int calculated_left = 0;
for (int i = 0; i < lv.Columns.Count; i++)
if (lv.Columns[i] == column)
return calculated_left;
else
calculated_left += lv.Columns[i].Width + 1;
return calculated_left;
}
