hi my name is vishal for past 7 i have been breaking on how to show each group box along with it's controls based on value in c# windows forms with sql server 2008.
i have 5 group boxes.
1.name:GrpStep1,enabled:true,visible:true(contains 8 labels,2combobox,3textboxes and 3 datetimepickers).
2.name:GrpBarCode,enabled:true,visible:true(contains GrpDEntry along with 1 label and 1 textbox).
3.name:GrpDEntry,enabled:true,visible:true(contains 2 radio buttons).
4.name:GrpStep2,enabled:true,visible:true(contains 1 textbox,1button and StrokeScribe control).
5.name:GrpStep3,enabled:true,visible:true(contains 1 combobox,2buttons,2 picture boxes and StrokeScribe control).
So GrpStep1 is the base group box,GrpBarCode is a group box is put on or embed on grpStep1,GrpDEntry in put on or embed on GrpBarCode,GrpStep2 in put on or embed on GrpBarCode and GrpDEntry and GrpStep3 is a group box which is visible to the designer at design-time.
Given is my code below in c# of what i have tried:

As you can see all my combobox functions works perfectly according to my expectations. But here is the problem the code works till it comes or shows GrpStep1 and after that the code does not perform any process.
Given below is code the same thing which i have done in vb6 with ms access with adodb and it works.

End Subwhat i want is in my c# code with sql server 2008 after processing till GrpStep1 upon clicking on next button in my frmDialyzer form i want to go to GrpStep2 and GrpStep3.
You can in my vb6 code the processing of each frame is done through value of dStepIndex value in my form in vb6.
I know i have to do some modifications in my c# code but i dont know how to do it can anyone help me please.! If anyone wants any details regarding controls in each group box please ask me in order to help me please ask.! Any help or guidance in solving this problem would be greatly appreciated.vishal
