[Custom Connector] How to implement checkbox?

Hi VietTran123,

 

Thanks for reaching out to the Microsoft fabric community forum and  your interest in creating a checkbox-like functionality within your Power BI custom connector. While Power BI doesn't support checkboxes natively in the connector interface.

There are several effective methods and workarounds to achieve similar functionality. Here’s how you can implement it:

 

You can write custom SQL queries in your connector to filter data based on user selections. While this doesn't create a physical checkbox, you can simulate checkbox behavior through option selection:

• Use a parameter that allows you to select multiple options. In your SQL query, filter data based on these selections.

Example Query:

SELECT * FROM YourTable WHERE YourColumn IN ('Option 1', 'Option 2');

Once the data is retrieved based on user input, you can further manipulate it:

• Create DAX measures or calculated columns that aggregate data according to the options chosen. This will allow your reports to dynamically respond based on input.

Query folding optimizes performance by executing queries at the database level rather than pulling unnecessary data into Power BI:

• Make sure your custom connector supports query folding. This means structuring your connector queries to utilize your selections effectively, ensuring efficient data retrieval.

Utilizing the M language gives you control over how data is transformed before it is loaded into Power BI:

• You can shape and filter data using M based on the selected parameters. For instance, if you select certain options, you can adjust the dataset loading accordingly.

By combining these methods, you can effectively create a functionality that create checkboxes. You will be able to select options, and the connector will respond dynamically, retrieving and filtering data accordingly.
