Hi every boDy..
i have some problem in .NET windows application...
My problem is, hOw can i Use Refresh Report Viewer Button in the Report in C# Form .. i mean that Usually on clicking on Refresh Report Viewer Button ,It Shows New Data, but here is sOme thing wrong, b/c when every i press it then its shows Old data not new one.
Your data sounds as though it is not being committed to your database, otherwise a refresh would retrieve the data and thus the data displayed would reflect the changes made.
Most databases/DBMS' require that the user explicitly commit changes to the database or the changes are merely dropped when a new transaction is initiated.
Consult your DBMS' literature referencing the procedures/processes for committing and rolling back changes/updates to tables, columns, and rows and you should find all the information your heart desires...hopefully.
Take care and happy hunting!
