c# - in Telerik RadDropDownList popup vs dropdown -

i programticly opening , closing control user has control open if there items in land in it.

i haveing bit of trouble telerik support cleared up. solution uses different methods mine (not related solution, else).

to cause control open doing (which works):

 private void order_con_name_dd_gotfocus(object sender, eventargs e)         {             if (!order_con_name_dd.ispopupvisible)             {                 order_con_name_dd.showdropdown(); 

however, suggesting using (which works)

 private void order_con_name_dd_gotfocus(object sender, eventargs e)     {         if (!order_con_name_dd.ispopupvisible)         {             radelement element = this.order_con_name_dd.dropdownlistelement.elementtree.getelementatpoint(this.order_con_name_dd.dropdownlistelement.pointfromscreen(control.mouseposition));             if (!(element raddropdownlistarrowbuttonelement))             {                 this.order_con_name_dd.dropdownlistelement.arrowbutton.performclick();             }         }     } 

for closing control doing (which works):

 private void dropdownlist_popupopened(object sender, eventargs e)         {            if (order_con_name_dd.ispopupvisible)             {                 order_con_name_dd.closedropdown(); 

and solution uses:

 private void dropdownlist_popupopened(object sender, eventargs e)         {            if (order_con_name_dd.ispopupvisible)             {                 order_con_name_dd.popup.closepopup(radpopupclosereason.keyboard); 

my question (and have researched not found far) - difference between these 2 working solutions?

ok...from hristo @ telerik:

regarding questions:

raddropdownlist.closedropdown method internally calls closepopup defined on popup object instance.

actually, there not different if calling performclick method of arrow button or raddopdownlist.showdropdownmethod. performclick method toggle popup state if open close , vice versa.
