 ## DESCRIPTION
 
-This command is an alternative to Out-Gridview. It works much the same way. Run a PowerShell command and pipe it to this command. The output will be displayed in an autosized data grid. You can click on column headings to sort. You can resize columns and you can re-order columns. You will want to be selective about which properties you pipe through to this command. See examples.

-You can specify a timeout value which will automatically close the form. If you specify a timeout and the Refresh parameter, then the contents of the datagrid will automatically refreshed using the timeout value as an integer. This will only work when you pipe a PowerShell expression to ConvertTo-WPFGrid as one command. This will fail if you break the command in the PowerShell ISE or use a nested prompt.

This will only work when you pipe a PowerShell expression to ConvertTo-WPFGrid as one command. This will fail if you break the command in the PowerShell ISE or use a nested prompt. Beginning with v2.4.0 the form now has a Refresh button which will automatically refresh the datagrid.
 
-Because the grid is running in a new background runspace, it does not automatically inherit anything from your current session. When refreshing data, you need to make sure that the command up to ConvertTo-WPFGrid can run in a standalone session. For example, avoid using variables that won't exist in the background runspace. However, you can use the -UserProfile parameter which will load your user profile scripts into the runspace.

However, you can use the -UserProfile parameter which will load your user profile scripts into the runspace. You can also specify a list of locally defined variables to be used in the form.
 
 This command runs the WPF grid in a new runspace so your PowerShell prompt will not be blocked. However, after closing the form you may be left with the runspace. You can use Remove-Runspace to clean up or wait until you restart PowerShell.
