Server-side Data Binding Overview

The article shows how to set up RadRadioButtonList with data binding.

RadRadioButtonList can use the standard data sources for binding an ASP.NET control:

Declarative ASP.NET data sources (SqlDatasource, ObjectDataSource, LinqDataSource, etc.)
Server-side collections that implement the IEnumerable interface.

Server-side Data Binding Basics

RadRadioButtonList exposes the Databindings composite property to configure the fields needed for data binding:

DataTextField binds the Text property of the items with the corresponding field.
DataValueField binds the Value property of the items with the corresponding field.
DataSelectedField binds the Selected property of the items with the corresponding field.
DataEnabledField binds the Enabled property of the items with the corresponding field.

Example 1: Data binding RadRadioButtonList with a collection in the code behind.

ASP.NET

<telerik:RadRadioButtonList runat="server" ID="RadRadioButtonList1">
    <Databindings DataTextField="Text" DataValueField="Value" 
        DataSelectedField="Selected" DataEnabledField="Enabled" />
</telerik:RadRadioButtonList>

C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        RadRadioButtonList1.DataSource = GetData();
        RadRadioButtonList1.DataBind();
    }
}

private IEnumerable<object> GetData()
{
    List<object> result = new List<object>() {
        new { Text = "English", Value = "en",
                Selected = true, Enabled = true },
        new { Text = "German", Value = "de",
                Selected = false, Enabled = true },
        new { Text = "french", Value = "fr",
                Selected = false, Enabled = true }
    };

    return result;
}
VB
Protected Sub Page_Load(sender As Object, e As EventArgs)
	If Not Page.IsPostBack Then
		RadRadioButtonList1.DataSource = GetData()
		RadRadioButtonList1.DataBind()
	End If
End Sub

Private Function GetData() As IEnumerable(Of Object)
	Dim result As New List(Of Object)() From { _
		New With { _
			Key .Text = "English", _
			Key .Value = "en", _
			Key .Selected = True, _
			Key .Enabled = True _
		}, _
		New With { _
			Key .Text = "German", _
			Key .Value = "de", _
			Key .Selected = False, _
			Key .Enabled = True _
		}, _
		New With { _
			Key .Text = "french", _
			Key .Value = "fr", _
			Key .Selected = False, _
			Key .Enabled = True _
		} _
	}

	Return result
End Function
