web.config Parameters
These are the appSetting
parameters you can set in your web.config file.
Put them in the <appSettings> section of the
file.
| Setting |
Description |
Note |
| AtalasoftWebControls_Cache |
Location of the cache relative to
the root of the application |
|
| AtalasoftWebControls_CacheFilesOnly |
Set to true if only files should
be put in the cache.
Set to false if it is OK to
create directories.
Default is true. |
Setting this value to false while using .NET 2.0
can cause the application to recompile while files are deleted from the cache.
Use the default setting for .NET 2.0. |
| AtalasoftWebControls_CacheLifeTime |
Number of minutes a file can live in the cache without being used.
Default is 20.
|
Set value to the length of time that a session is allowed to stay alive
before it times out. |
| AtalasoftWebControls_DisableCache |
Set to true to disable the image cache.
The default is "false". |
Use this option only if you are never going to need to
modify images, load them from a direct file path, or you are saving them
yourself. This turns off warnings for the Cache, and may render the control unusable.
Use at your own risk. |
| AtalasoftWebControls_ErrorLogging |
Set to true to enable the error log. The
default is false
. |
Log files will be placed in the Cache alongside images and time stamps for
the same session. These files are automatically cleaned up when the session is
cleaned up. |
| AtalasoftWebControls_ResourcePath |
Set the location of Javascript and
Image resources required by the control. |
Before version 4.0, this was a property of the control, but now must be set
in the web.config. If it is not set,
resources are requested from the control assembly, which is slower. |
| AtalasoftWebControls_ShowClientErrors |
Set to true to
show JavaScript errors in the browser.
Set to false otherwise.
The default is
true
|
|
