Form

in namespace DotVVM.Framework.Controls.Bootstrap4

Renders a Bootstrap form.

Usage & Scenarios

Renders a Bootstrap form. Each form field is wrapped in the FormGroup control.

https://getbootstrap.com/docs/4.3/components/forms/

Sample 1: Form Controls

The Form is an easy to use control which uses the Bootstrap styles to render a form.

The Type property specifies the layout of the form - Default, Horizontal or Inline.

page.dothtml
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: Boolean1}" IsInline="true" />
  </bs:FormGroup>
  
  <bs:FormGroup LabelText="RadioButton">
    <bs:RadioButton Checked="{value: Boolean2}" CheckedValue="{value: true}" IsInline="true" Text="yes" />
    <bs:RadioButton Checked="{value: Boolean2}" CheckedValue="{value: false}" IsInline="true" Text="no" />
  </bs:FormGroup>

</bs:Form>

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.Form.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 Boolean1 { get; set; }

        public bool Boolean2 { get; set; }
    }
}

Sample 2: Horizontal Form Label Sizing

If the form is in the Horizontal mode, the labels are placed next to the form fields.

In this case, you have to specify how wide the labels should be (how many columns they will occupy). You can use the LabelSize to provide a default size for all screens, and use LabelSizeSM, LabelSizeMD, LabelSizeLG and LabelSizeXL properties to override the label width for a particular screen size.

If you have customized Bootstrap grid system to have different number of columns, use the NumberOfColumns property on the Container control.

page.dothtml
ViewModel.cs

<bs:Form Type="Horizontal" LabelSizeXS="2" LabelSizeLG="8">
  <bs:FormGroup LabelText="Label size would be different on different screen sizes">
    <bs:CheckBox Text="Simple Test 1" Checked="{value: CheckBox1Checked}" />
    <bs:CheckBox Text="Simple Test 2" Checked="{value: CheckBox2Checked}" />
    <bs:CheckBox Text="Simple Test 3" Checked="{value: CheckBox3Checked}" />
  </bs:FormGroup>
</bs:Form>

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.Form.sample3
{
    public class ViewModel : DotvvmViewModelBase
    {
        public bool CheckBox1Checked { get; set; }
        public bool CheckBox2Checked { get; set; }
        public bool CheckBox3Checked { get; set; }

    }
}
