Blazor Query Builder - Column Templates

This sample demonstrates the Column Template functionality in QueryBuilder component using DropDownList and RadioButton components. In the Country column, users can change the Operator as equal/not equal using the RadioButton component and select the Value from the DropDownList component.

This sample illustrates how to integrate the ColumnTemplate to the columns in the QueryBuilder. It is used for creating a custom user interface for the columns with custom components and updating the rule collection by handling component events. This can be specified using the ColumnTemplate directive of the QueryBuilderColumn directive. Inside the template, the data can be accessed using the implicit named parameter Context.

More information about the Blazor QueryBuilder Column Template can be found in this documentation section.
