Ajax

The follow pages contain live running PowerShell scripts that have been enhanced to support ATPowerForm's web rendering ability. Since these script are running in a shared hosting environment normal administrative PowerShell functions will not be presented. This can be done via the Trial download, all sample are included with the product.

PowerShell - Ajax Demo

The Ajax Demo shows the ability of ATPowerForm to handle PowerShell processing via asynchronous Ajax executions. ATPowerForm allows any displayed field or operation to be Ajax enabled or not. The form below demonstrates three types or ATPowerForm Ajax field definitions. Non-blocking allow Ajax calls to be performed without blocking the user from updating another field (can cause potential issues on slower systems, causing the any PowerShell results to be lost since only one Ajax call can be made at a time). Field Blocking displays a progress bar only over the field that was updating (not blocking users from making other changes). Then lastly is Page blocking where the entire page is blocked until the update is completed.

Type anything then TAB or click off the control to see the response.
