I wrote this library so I don’t have to keep track if I should use HttpRuntime.Cache, AppDomain.CurrentDomain.SetData, HttpContext.Current.Session, or a Dictionary…now I just use GlobalCache or UserCache. It also makes unit testing a webapp a snap, because if you use IGlobalCache/IUserCache in your code, you just inject the Windows-based cache in your unit test setup.
You can download the solution with dlls here: Universal Caching solution
Do you have a post action that accepts a parameter (and what post action doesn’t?), but you also have a get action that accepts a parameter and you are seeing that submits are going back to the get action and other strange behavior? Here’s how you fix that:
I thought I’d quickly mention this nice time-saver added in .NET 4.0: string.IsNullOrWhiteSpace. It works just like IsNullOrEmpty but also checks to see if there’s nothing but spaces in the string, so you don’t have to Trim before checking.
If you have a entity with a nested entity, you can show the nested entity’s properties with a little trick.
For example if you have these business objects:
public class MyObj
{
public MyOtherObj MyProperty { get; set; }
}
public class MyOtherObj
{
public int SomeProperty { get; set; }
}
If you want to show a field from MyProperty (e.g. MyOtherObj.SomeProperty), and MyObj is your report’s datasource, your report fieldbox will need to look like this:
First(Fields!MyProperty.Value.SomeProperty)
(NOTE: do not add “.Value” onto the end of the property name as normal, it will produce a #error at runtime).
Shows X-checked box or empty box in your RDLC report and displays correctly when exported to PDF (change the textbox’s font to Wingdings2):
=IIf( Fields!MyBooleanField.Value, Chr(83), Chr(163))
