Sometimes asp.net web page shows blank page although it is consist of Crystal report viewer.
Cause of Problem
- Using client tools (debug window of your browser) or server tool (IIS log) you will find that some files (
style.css ) are not served;
- these files are placed by CR installer in
wwwroot\aspnet_client folder but they cannot be reached;
- If you installed your application in a website different from
aspnet_clientfolder is not placed inside that website
Few days ago I worked on a project where database table has more than 80 columns. My client asked to create a search so that it can search through all the columns. So I have decided to create an extension method which will search through all the columns in DataTable. Creating generic method or extension for searching through all the columns in DataTable in C#.
It is difficult to write a SQL query (when table has many columns) which will search through all the columns.
