Search for multiple fields in Combo Box

By default, we can display only one field in Combo Box and Search for only one field in Combo Box.

There is a requirement to display multiple fields and also search for multiple fields in Combo Box. For example, we have EmployeeDetails as the Data should display Employee Name and Employee Email ID and can also search the record using same.

Modify below parameters of ComboBox:

Items: EmployeeDetails
DisplayFields: ["EmployeeName","EmployeeEmailID"]
SearchFields: ["EmployeeName","EmployeeEmailID"]

We can use this for ID and Definition Column types as well.

Check if a Table in Data Source is empty

Akanksha GuptaLeave a comment

To check whether a table in data source is empty or not, use IsEmpty

IsEmpty(tableName)

This is equivalent to CountRows(tableName)=0

We cannot use CountRows() directly on data source as it generally gives Delegation warning (Depends on the Connector)

If IsEmpty(tableName) returns true, this indicates that your Data Source table has no rows.

Convert values selected from Combo Box to a Comma separated string

Akanksha GuptaLeave a comment

I have a Combo Box with dummy values A, B, C , D and multi-select On. I want to select multiple values and display them in a Label as comma-separated string

For this, we can use function Concat. Below is an example for the same

As these are hardcoded values in Combo Box, I took Value in Concat function.

If you are getting these values dynamically, you can also use Result.
