grid & drop down

As posted on Feb 18, 2009 10:33: just to clarify: are you saying that on all grids, if a column is set to coro and the user enters the edit mode on the last cell, the drop down will always go off the grid so the user cannot see it, and there is no fix for this. do i have this correct?

You answered there's no fix for this issue. We've bought the 'professional' enterprise edition and I allmost can't believe this. This makes the grid allmost useless. I never expected dhtmlx components within layouts would act like this and think it's more a bug than a 'pretty complicated' issue to be resolved by our developers. I'am quiet disappointed about it, can this really not be fixed!?

Hello,

unfortunately, currently it isn't possible to create universal solution.

But it is possible to open combo always in top position (above the edited cell) - possibly this approach will be appropriate. 

It can be done using onEditCell event handler:

dhxGrid.attachEvent("onEditCell",function(stage,id,index){
  if(index==COLUMN_INDEX && stage==1){
      this.editor.list.style.top = parseInt(this.editor.list.style.top)- this.editor.list.offsetHeight-20+"px";
  }
  return true
})
Here COLUMN_INDEX is index of the "co" column.
