In Merge Replication How To Insert A Data??? Program Is Getting Stuck

Hi all,


there are 2 datagrids i have taken,

1st for displaying data before inserting the value into table
2nd for displaying data after inserting the value into table
just see the screeenshot which i have taken


actually the problem is, we are not getting any type of errors even though I have try/catch blocks.
I have colored that particular statement in RED color, where it is getting stuck, while executing, if we sit 40-45 minutes then also the execution pointer is not going on next step.




please look into this, and if u have any idea/person by which/whom we can solve this then please tell us.......
