ButtonGroup

in namespace DotVVM.Framework.Controls.Bootstrap

Renders the Bootstrap button group widget.

Usage & Scenarios

Renders a group of Bootstrap buttons.

https://getbootstrap.com/docs/3.3/components/#btn-groups

Sample 1: ButtonGroup Size

The Size property specifies how big the buttons will be. The available sizes are: Large, Default, Small and ExtraSmall.

Be sure to use the <bs:Button> instead of the <dot:Button> controls inside the button group.

You can also use <bs:DropDownButton>, <bs:CheckBox> or <bs:RadioButton> inside.

page.dothtml
ViewModel.cs

<bs:ButtonGroup Size="ExtraSmall">
  <bs:Button Click="{command: DoSomething()}" Text="Button 1" />
  <bs:Button Click="{command: DoSomething()}" Text="Button 2" />
  <bs:DropDownButton Text="Dropdown">
    <Items>
      <bs:DropDownButtonItem NavigateUrl="https://www.google.com">
        Google
      </bs:DropDownButtonItem>
      <bs:DropDownButtonItem NavigateUrl="https://www.youtube.com">
        Youtube
      </bs:DropDownButtonItem>
    </Items>
  </bs:DropDownButton>
</bs:ButtonGroup>

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ButtonGroup.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {

        public void DoSomething()
        {
        }
    }
}

Sample 2: Justified Buttons

Using the IsJustified property you can tell the ButtonGroup to use all the space available in the horizontal direction.

page.dothtml
ViewModel.cs

<bs:ButtonGroup IsJustified="true">
  <bs:Button Click="{command: DoSomething()}" Text="Button 1" />
  <bs:Button Click="{command: DoSomething()}" Text="Button 2" />
  <bs:Button Click="{command: DoSomething()}" Text="Button 3" />
  <bs:Button Click="{command: DoSomething()}" Text="Button 4" />
</bs:ButtonGroup>

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ButtonGroup.sample2
{
    public class ViewModel : DotvvmViewModelBase
    {

        public void DoSomething()
        {
        }
    }
}

Sample 3: Vertical Buttons

The IsVertical property switches the ButtonGroup control into the vertical mode.

page.dothtml
ViewModel.cs

<bs:ButtonGroup IsVertical="true">
  <bs:Button Click="{command: DoSomething()}" Text="Button 1" />
  <bs:Button Click="{command: DoSomething()}" Text="Button 2" />
  <bs:Button Click="{command: DoSomething()}" Text="Button 3" />
  <bs:Button Click="{command: DoSomething()}" Text="Button 4" />
</bs:ButtonGroup>

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ButtonGroup.sample3
{
    public class ViewModel : DotvvmViewModelBase
    {

        public void DoSomething()
        {
        }
    }
}

Sample 4: CheckBoxes and RadioButtons in the ButtonGroup

The ButtonGroup also supports CheckBox and RadioButton.

Remember that Bootstrap doesn't support the Size and IsVertical modifiers when checkboxes or radio buttons are inside the button group.

Also make sure to use the <bs:CheckBox> and <bs:RadioButton> instead of the <dot:CheckBox> and <dot:RadioButton> controls. The builtin controls are not supported in the ButtonGroup.

page.dothtml
ViewModel.cs

<bs:ButtonGroup IsJustified="true">
  <bs:CheckBox Text="CheckBox 1" Checked="{value: Checked1}" />
  <bs:CheckBox Text="CheckBox 2" Checked="{value: Checked2}" />
</bs:ButtonGroup>
<p>CheckBox 1:{{value: Checked1}}</p>
<p>CheckBox 2:{{value: Checked2}}</p>

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ButtonGroup.sample4
{
    public class ViewModel : DotvvmViewModelBase
    {

        public bool Checked1 { get; set; }

        public bool Checked2 { get; set; }
    }
}

Sample 5: CheckBoxes in Repeater and ButtonGroup

You can combine the CheckBoxes and RadioButtons with the Repeater in the ButtonGroup control. Use the CheckedItems and CheckedValue properties to bind these checkboxes to a collection in the viewmodel.

Because we don't want the Repeater to render its wrapper <div> element, the ButtonGroup will switch the RenderWrapperTag property to false automatically.

page.dothtml
ViewModel.cs

<bs:ButtonGroup>
  <dot:Repeater DataSource="{value: CheckBoxes}">
    <ItemTemplate>
      <bs:CheckBox Text="{value: Text}" 
                   CheckedItems ="{value: _parent.Colors}" 
                   CheckedValue="{value: CheckedValue}" 
                   Changed="{command: _parent.UpdateSelectedColors()}"/>
    </ItemTemplate>
  </dot:Repeater>
</bs:ButtonGroup>

<p>{{value: SelectedColors}}</p>

using DotVVM.Framework.ViewModel;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ButtonGroup.sample5
{
    public class ViewModel : DotvvmViewModelBase
    {
        public List<CheckBox> CheckBoxes { get; set; }

        public string SelectedColors { get; set; }
        public override Task PreRender()
        {
            CheckBoxes = new List<CheckBox>();
            CheckBoxes = GetData();
            return base.PreRender();
        }
        public ViewModel()
        {
            Colors = new List<string>();
            Colors.Add("red");
            Colors.Add("green");
        }
        public List<string> Colors { get; set; }

        public void UpdateSelectedColors()
        {
            SelectedColors = string.Join(", ", Colors.Select(i => i.ToString()));
        }

        private List<CheckBox> GetData()
        {
            return new List<CheckBox>
            {
                new CheckBox()
                {
                    Text="CheckBox 1",
                    CheckedValue = "red"
                },
                new CheckBox()
                {
                    Text="CheckBox 2",
                    CheckedValue = "blue"
                },
                new CheckBox()
                {
                    Text="CheckBox 3",
                    CheckedValue = "green"
                }



            };
        }
    }

    public class CheckBox
    {
        public string Text { get; set; }
        public string CheckedValue { get; set; }



    }
}
