I am trying to add a Multi-select control in my UI, a Data page is used to get the data in the Multi-select control. The data page is populating the data correctly but my Multi-select is not showing any data, it is just appearing as a blank control in the UI. Please suggest on how to populate the data in Multi select control using a data page.
If you are using multiselect control in modal dialog or table layout it is not supported as per below explanation:
Below is the difference in rendering between templatized and non-templatized control:
Templatized control renders on client side. On screen load the metadata is send by the server later on the specific content is getting load. In non-template control, the whole data is getting loaded on the server side and the result is shown on the screen.
In the multiselectcontrol on the grid the section that is getting loaded is non-template and the multiselect control is templatized control. On screen load, the section getting loads the whole script with data whereas the multiselect control loads only the metadata and on second refresh it loads the data related to that previously loaded metadata.
This is the reason why the template control is not getting loaded in the non-template section.
Advanced parameter sections are rendering as non-template causing new controls like multiselect not to render.
