How to disable and enable button by selecting multi-selected dropdown widget in thingworx.

I want to validate the button when I select the multi-selected dropdown values, the button should be enabled, and vice versa.

Hi @Hrishabh.Sharma 

You can create a service to validate multiple selected rows and based on that you can enable and disable the button

Create service with infotable input 

var result = true;
// selectedValue : InfoTable Input
// If Infotable contains multiple rows
if(selectedValue && selectedValue.length > 1)
{
    // enable button
    result = false;
}

Mashup Binding should look like this :

Mashup will look like this :

When multiple value selected button will enable

Instead of the extra service https://github.com/doubleSlashde/InfotableInspectorWidgetTWX could be used to get Selected-RowCount in Frontend and evaluate button "disabled"-state via expression. But needs the extra extension - depending on how often it is needed the extension may be useful.
