FormGroup

in namespace DotVVM.Framework.Controls.Bootstrap4

Represents a group in the Form control.

Usage & Scenarios

The FormGroup is used inside the Form control and renders a form field with a label.

https://getbootstrap.com/docs/4.3/components/forms/#form-groups

Sample 1: FormGroup Usage

Place any content inside the FormGroup control.

The TextBox and ComboBox controls will get the class="form-control" automatically so they'll get the default Bootstrap look.

If you use the CheckBox and RadioButton controls, make sure you use <bs:CheckBox> and <bs:RadioButton> instead of <dot:CheckBox> and <dot:RadioButton> controls.

ViewModel.cs

<bs:Form Type="Default">

  <bs:FormGroup LabelText="TextBox">
    <bs:TextBox Text="{value: Text}" />
  </bs:FormGroup>

  <bs:FormGroup LabelText="ComboBox">
    <bs:ComboBox DataSource="{value: Items}" SelectedValue="{value: Item}" />
  </bs:FormGroup>

  <bs:FormGroup LabelText="CheckBox">
    <bs:CheckBox Checked="{value: IsChecked}" IsInline="true" />
  </bs:FormGroup>

  <bs:FormGroup LabelText="RadioButton">
    <bs:RadioButton Checked="{value: Radio}" CheckedValue="{value: true}" IsInline="true" Text="yes" />
    <bs:RadioButton Checked="{value: Radio}" CheckedValue="{value: false}" IsInline="true" Text="no" />
  </bs:FormGroup>

</bs:Form>

Text: {{value: Text}} <br />
ComboBox: {{value: Item}} <br />
CheckBox: {{value: IsChecked}} <br />
RadioButton: {{value: Radio}} <br />

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.FormGroup.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public string Text { get; set; }

        public string[] Items => new[] { "one", "two", "three" };

        public string Item { get; set; } = "one";

        public bool IsChecked { get; set; }

        public bool Radio { get; set; }
    }
}

Sample 2: FormGroup LabelTemplate

If you need custom content in the label, just use the LabelTemplate property instead of LabelText.

page.dothtml
ViewModel.cs

<bs:Form>
  <bs:FormGroup>
    <LabelTemplate>
      Your favorite colors
      <bs:Button Text="Send" Click="{command: DoSomething()}"></bs:Button>
    </LabelTemplate>
    <FormContent>
      <bs:CheckBox Text="Red" Checked="{value: Red}" IsInline="true" />
      <bs:CheckBox Text="Blue" Checked="{value: Blue}" IsInline="true" />
    </FormContent>
  </bs:FormGroup>
  <span>{{value: Text}}</span>
</bs:Form>

public class ViewModel : DotvvmViewModelBase
{
    public bool Red { get; set; } = false;
    public bool Blue { get; set; } = true;
    public string Text { get; set; }
    public void DoSomething()
    {
        if (Red && Blue)
        {
            Text = "You selected two colors";
        }
        else
        {
            Text = "You selected only one color";
        }
    }
}
