Thank you for the question.

I tested the case using our latest release - Q1 2011 SP1 and I was not able to reproduce the issue.
Could you please try to modify the attached project in order to reproduce the experienced behavior? Please note that you should open a new support ticket in order to be able to attach files.

Thank you for your time and cooperation.

I am looking forward to your reply.

Feel free to write back, we will be glad to help.

Hello, 

I'm DenisCL. Since I've lost my ids, i'll post from now with this account.

I have a simple question, regarding the code you previously gave me for the dropdownlist max sized popup.

I need the same but for ComboboxColumn in radgridview !

I found how to do it, but I find difficulties to get the current dropdownlist in the radgridview.  I saw we can use the activeEditor for getting the elementEditor and then go ahead.

But the active editor is null, and I 'm stuck.

Any ideas?

Here is my code 

            RadDropDownListEditor editor = radGridView1.EditorManager.ActiveEditor as RadDropDownListEditor;
            if (editor != null)
            {
                _element = editor.EditorElement as RadDropDownListEditorElement;
                if (_element != null)
                {
                    _element.PopupOpened += element_PopupOpened;
                }
            }

Can you tell me how to access to the dropdownlist  in a cell properly please?

thanks

Sorry for double post...

I could finally obtain what I need.

here is the code

This first function register events on popup and keypress asap the editor is initialized

  void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
        {
            if (_element == null)
            {
                var editor = radGridView1.EditorManager.ActiveEditor as RadDropDownListEditor;
                if (editor != null)
                {
                    _element = editor.EditorElement as RadDropDownListEditorElement;
                    if (_element != null)
                    {
                        _element.PopupOpened += element_PopupOpened;
                        _element.KeyPress += _element_KeyPress;
                    }

                }
            }
        }

Then when we open the dropdownlist, it checks the width of every item and take the biggest width. I add 50 for including scrollbar width

 void element_PopupOpened(object sender, EventArgs e)
        {
            SetDropDownSize();
        }

        private void SetDropDownSize()
        {
            int choixPlusLarge = _element.Items.Select(item => TextRenderer.MeasureText(item.Text, item.Font).Width).Concat(new[] {0}).Max() + 40;
            _element.Popup.MinimumSize = new Size(choixPlusLarge, _element.Popup.Height);
        }
