ComboBoxFormGroup
in namespace DotVVM.Framework.Controls.Bootstrap4
Renders a FormGroup control with a ComboBox
Usage & Scenarios
Sample 1: Form Group properties
ComboBoxFormGroup is just wrapper around ComboBox inside FormGroup, so you can use any of the properties of the FormGroup and ComboBox to configure desired behavior.
For example you can use the Label property to set the Label of the FormGroup.
<bs:Form>
<bs:ComboBoxFormGroup DataSource="{value: Fruits}" SelectedValue="{value: SelectedFruit}" LabelText="Fruits" />
</bs:Form>using DotVVM.Framework.ViewModel;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap4.ComboBoxFormGroup.sample1
{
public class ViewModel : DotvvmViewModelBase
{
public string[] Fruits { get; set; } = { "Apple", "Banana", "Orange" };
public string SelectedFruit { get; set; }
}
