Hi
I want to create a modal window using $header variable from Page-Data_Rendering event.
How should I proceed?
Why don’t you use Javascript code in Startup Script section instead?
There should be an icon for the user to open the popup with help on the table below
Perhaps you may try How to Display View/Edit Page in Modal Dialog that Belongs to Another Tables (v2021).Just assign the $header param in Page_DataRendering server event in order to display the link to the Modal dialog.
