16.5.2.2 Passing Client Data Directly to Dialogs

Open a dialog with dynamic client-side values by substituting page item placeholders in a URL template.

To pass dynamic client data to a dialog directly, thus avoiding a server round trip:

• Use APEX_PAGE.GET_URL to default a dialog URL template with page item value placeholders
• Use a JavaScript helper function to substitute the page item placeholders and open the dialog
• Call the helper function in a triggered action to open the dialog, passing in the template URL
• Disable session state protection on the target dialog page item receiving the dynamic value.

• Defaulting URL Template Page Items
  Use APEX_PAGE.GET_URL to compute the template URL containing page item placeholders you replace with client values when opening the dialog.
• Substituting Client-Side Data in Dialog URL
  
• Opening Dialog, Passing Client-Side Data
  Open modal drawer and dialog pages by passing a URL template to JavaScript helper functions
• Unprotecting Dynamic Client Arguments
  Relax session state protection for dialog page items that receive dynamic client-modifiable values.
