Hello kamran815! :)
It looks like you're using ADO.NET to connect to your data stored (i.e. mysql). Is that an absolute must or are you open to using LINQ? The LINQ methods have simplified access to data from RDBMS. Take a look at this tutorial if you're not familiar with it: https://msdn.microsoft.com/en-us/data/ff728653.aspx

Let me know if you have any questions:


Hello again kamran815...
Looking over your code, it looks like you're planning to scroll through each record one by one. I'm not certain what your requirements and specs are for this application, but if you just need to pull up records, and say, access them for editing, you might try using the GridView control, and a Master/Detail pattern.
