Bind DataProvider of DropDownBox from SessionVar

Ask Questions

Hello, greetings to everyone!

Does anybody know whether there is a possibility in mappView to bind a DataProvider to SessionVar?

According to Automation Help datatype of DataProvider is ItemCollection. But if I want to create a SessionVar of this type I get this error:

18	Error	08.01.2024 12:18:56,0230	This is an invalid xsi:type 'http://www.br-automation.com/iat2015/session/engineering/v1:ItemCollection'., XML syntax error. The object cannot be loaded.		Ln:32, Col:4	D:\AS\Projekte\TestProject\Logical\mappView\Visualizazion\Variables\Vars.svar

Syntax of SessionVar:

<Variable name="DataProvider_A" xsi:type="ItemCollection" value="[{'value':'0','text':'AAAA'},{'value':'1','text':'BBB'}]" />

Is there a possibility to create a string array or something similar?

Background: I want to replace DataProvider dynamically via ListBinding.

Many thanks in advance for your help and ideas. :slight_smile:

@Simon_Stoll
have you tried using just STRING?

I did and while you can’t select the variable type thru the binding wizard it seems to be working with a manually created binding.

Session var:

<Variable name="Variable3" xsi:type="ANY_STRING" value="[{'value':'0','text':'AAAA'},{'value':'1','text':'BBB'}]" />

Binding:

	<Binding mode="twoWay">
		<Source xsi:type="session" refId="Variable3" attribute="value" />
		<Target xsi:type="brease" contentRefId="TestContent" widgetRefId="DropDownBox1" attribute="dataProvider" />
	</Binding>

Hey Marcel,

works perfect. Thank you so much!!

Only issue is that ANY_STRING isn’t available for DataProvider in content editor. But I can work with this.

Awesome, good to hear it works for you as well.

I think it is possible.
