Hi , 

we have requirement that we need load controls like labels, text boxes,drop down,date time,user control etc  at run-time based on our table record.actually are designing questionnaire fill form.questions/answere we get from tables . so its dynamic . 

we find out  GridBagLayoutPanel  which is pretty fast at adding control. design time its fine. but we need load control at run time actually. 

what problem i facing ? 

I've facing problem when i need add new control in middle of some control. 

let say i have drowpdown control with value yes/no . user click on yes.we need add another new control just below dropdown.

let say dropdown control GridBagConstraint OriginX=0 and OriginY=3 . 

below dropdown there will be already some control with origin x=0 , originy=4 and so on . if i need add control in originx=0 and originY=4. then how other controls GridBagConstraint origin values will be change accordingly?? 

e.g we have 4 columns record in table . 

column1 ,             column2 ,                 column3 ,            column4

lblQ1(x0,y0)       , textbox (x1,y0)    ,     lblQ2 (x2,y0)     , datetimepicker(x3,y0)

lblQ3 (x0,y1)       ,DropDown(x1,y1),    lblQ4   (x2,y1)   , Checkboxes (x3,y1)

blQ5 (x0,y2)       , textbox (x1,y2)  ,      lblQ6 (x2,y2)    , datetimepicker(x3,y2)

lblQ7 (x0,y3)       ,DropDown(x1,y3),    lblQ8(x2,y3)     , Checkboxes(x3,y3) 

so let say when user will click on first dropdown of second row (DropDown(x1,y1)) on selected index change i want to add another user control below it.so that it would look like below now.  need span column also here. 

column1 ,             column2 ,                 column3 ,            column4

lblQ1(x0,y0)       , textbox (x1,y0)    ,     lblQ2 (x2,y0)     , datetimepicker(x3,y0)

lblQ3 (x0,y1)       ,DropDown(x1,y1),    lblQ4   (x2,y1)   , Checkboxes (x3,y1)

|-----------------------------------------------------------------------------------------------------
|   this box is usercontrol or groupbox,with controls                                         | (x0,y2) spanX4 
|____________________________________________________________|

blQ5 (x0,y3)       , textbox (x1,y3)  ,      lblQ6 (x2,y3)    , datetimepicker(x3,y3)

lblQ7 (x0,y4)       ,DropDown(x1,y4),    lblQ8(x2,y4)     , Checkboxes(x3,y4) 

as u can see next control originX,Y values change,moved to next postion. 

how can i do that job at runtime  now ? can u please help me ?
