C# .Net combobox selected item used as Input of a sql SP

Question

Hi All,

 

I am  very new to .Net technology. I am working on a migration project where we are migrating PowerBuilder application to C# .Net windows application.

 

I have created  a windows form (UI) having 2 comboBox, 1 CheckBox , 1 DataGridView and a Search button,  used for fetching data in datagridview .  I need to select an item in Combobox1 which automatically refreshes  the items of the combobox2 . This two combobox uses SQL stored Procedure to work. 

And now checking the or un-checking the CheckBox will fetch and display the data in the DataGridView... Again fetching the data in datagridview uses a SQL Stored Procedure. 

 

Please help me resolving the issue.

 

If my problem is not clear please drop me a mail at ([email protected]) so that I can explain the requirement in much details...

 

Thanks
