Create dynamic text ID in MappView

Hi

I would like to change the Page Titel, depending on the actual active Page.

For this, I created an “session event” to first of all detect the change Page (currentPageId has changed).

  • I added a method to get the acutal PageId

  • I’ve added an widget action to change the TextOutput value, and therefore change the titel on the page

  • my intention was to use the ID of the actual page, which I get from the method, to create a dynamic text assignment of a text from the textlist to the textoutput widget

  • Is it possible to make the “value” in the widget action dynamic with the Operand PageID I get from the method?

Hi Stefan,

you could use an IndexText snippet for this use case.

See example in help:

IndexText Snippet mit Binding einer OPC UA Variable

Instead of binding a OPC UA variable you can bind SystemVar to Snippet

<Binding mode="oneWay">
   <Source xsi:type="session" refId="::SYSTEM:clientInfo.currentPageId" attribute="value" />
   <Target xsi:type="snippet" refId="IndexTextSnippet" attribute="value" />
</Binding>

Value of snippet you can bind to widget:

<Binding mode="oneWay"> 
   <Source xsi:type="snippet" refId="IndexTextSnippet" attribute="value" /> 
   <Target xsi:type="brease" widgetRefId="toPageId" contentRefId="Content1" attribute="value" /> 
</Binding

Sincerly Simon :slight_smile:
