Tree in SQL database
Tree in database table using Parent / Id relationship, uses AJAX and TreeGrid ASP.NET framework
Do not run this file locally!
Run it from your local or remote web http server where is installed IIS and ASP.NET (1.0, 1.1, 2.0, 3.0, 3.5, 4.0, 4.5, ...).
Source files: TreeFramework.html
(this html page),
TreeDef.xml
(static XML layout),
TreeFramework.aspx
(server script generates and processes XML data),
../Database.db
(source SQL database, table
TreeData)
../Framework/TreeGridFramework.aspx
(TreeGrid ASP.NET framework support script, included into
TreeFramework.aspx script)
This example uses
SQLite
../Database.db file as source SQL database.
You can switch to MS Access
MDB database by uncomment the line "Data Source=..." in TreeFramework.aspx.
The MS Access MDB database can be used only in 32bit mode of IIS.
Also the ASP.NET service program must have write access to the Database.mdb file.
To permit 32bit application on 64bit IIS, go to IIS manager, display application pools list (usually in root under computer name).
Choose DefaultAppPool (or the pool you use for the ASP.NET applications the TreeGrid examples are run on), select Advanced configuration and set Permit 32bit application to true.
