Namespace: Syncfusion.Blazor.QueryBuilder
Assembly: Syncfusion.Blazor.dll
Syntax
public class QueryBuilderColumns : SfOwningComponentBase, IComponent, IHandleEvent, IHandleAfterRender, IDisposable
Remarks

The QueryBuilderColumns component is used to declaratively specify the columns available for creating rules in the Query Builder. Each child QueryBuilderColumn defines the properties of a single column.

Examples

The following example demonstrates how to define columns for the Syncfusion.Blazor.QueryBuilder.

<SfQueryBuilder TValue="EmployeeDetails">
    <QueryBuilderColumns>
        <QueryBuilderColumn Field="EmployeeID" Label="Employee ID" Type="ColumnType.Number"></QueryBuilderColumn>
        <QueryBuilderColumn Field="FirstName" Label="First Name" Type="ColumnType.String"></QueryBuilderColumn>
        <QueryBuilderColumn Field="HireDate" Label="Hire Date" Type="ColumnType.Date" Format="dd/MM/yyyy"></QueryBuilderColumn>
    </QueryBuilderColumns>
</SfQueryBuilder>

@code {
    public class EmployeeDetails
    {
        public int EmployeeID { get; set; }
        public string FirstName { get; set; }
        public System.DateTime HireDate { get; set; }
    }
}
