Refer the below table to know about the available fields

url

html-attribute

It defines the HTML attributes such as class and styles for an button item.

link-attribute

It defines the image attributes such as height, width, styles, etc.

Local Data

To set the local JSON data, define a JSON array and initialize the GroupButton with dataSource property. Specify the column names in the fields’ property.

NOTE

the columns are bounded automatically when the fields are specified with the default names like id, text, etc…

Below is the sample to code to render the GroupButton JSON dataSource,

  • cshtml
  • /*ej-Tag Helper code to render GroupButton*/
    
    <ej-group-button id="GroupButton" width="100%" group-button-mode="@GroupButtonMode.RadioButton" show-rounded-corner="true" datasource="ViewBag.datasource">
        <e-group-button-fields id="BtnID" text="Text" content-type="ContentType" selected="Selected" />    
    </ej-group-button>
  • cshtml
  • /*Razor code to render GroupButton*/
    
         @{Html.EJ().GroupButton("GroupButton").Width("100%").GroupButtonMode(GroupButtonMode.RadioButton).ShowRoundedCorner(true).Datasource((IEnumerable<Groupbutton_core.ButtonController.Groupbutton>)ViewBag.Model).GroupButtonFields(e => e.Text("text").Selected("Selected")).Render(); }

    NOTE

    To render the GroupButton Control you can use either Razor or Tag helper code as given in the above code snippet.

  • c#
  • // Add the following code to add list items in the controller page
    	public class Btn
            {
                public string Text { get; set; }
                public string ContentType { get; set; }
                public string BtnID { get; set; }
                public string Selected { get; set; }
            }
            List<Btn> file = new List<Btn>();
            public IActionResult Index()
            {
                file.Add(new Btn { BtnID = "btn1", Text = "Day" });
                file.Add(new Btn { BtnID = "btn2", Text = "Week" });
                file.Add(new Btn { BtnID = "btn3", Text = "Work Week" });
                file.Add(new Btn { BtnID = "btn4", Text = "Month", Selected="selected" });
                file.Add(new Btn { BtnID = "btn5", Text = "Agenda" });
                ViewBag.datasource = file;
                return View();
            }

    Remote Data

    To bind remote data to the GroupButton, you can assign a service data as an instance of ejDataManager to the dataSource property along with the fields mapping.

  • cshtml
  • <ej-group-button id="groupButton" query="ej.Query().from('Orders').take(6)" width="100%">
        <e-datamanager url="//mvc.syncfusion.com/Services/Northwnd.svc/" offline="false"></e-datamanager>
        <e-group-button-fields text="CustomerID" />
    </ej-group-button>
