Usage
The DynamicInstallerRequirementValidator is an implicit data validator for checking a set of conditions on each panel change.
Example
<dynamicinstallerrequirements>
<installerrequirement severity="error"
condition="this.condition.must.not.happen"
messageid="this.condition.must.not.happen.translation.id"/>
<installerrequirement severity="error"
condition="this.condition.may.happen"
messageid="this.condition.may.happen.translation.id"/>
...
</dynamicinstallerrequirements>
If a condition applies, a messagebox is shown with the appropriate content from translation. Depending on the value of severity attribute the installation might be continued or is aborted:
- "error"
The messagebox is shown and the installation aborts. - "warning"
The messagebox is shown and the installation can continue after the OK button is pressed.
