Server-side Programming Overview

Updated on May 20, 2026

Overview of the Server-side APIs you can use to create and configure the Telerik WebForms SegmentedControl.

Creating the SegmentedControl in the Markup

To create a SegmentedControl in the markup, add the RadSegmentedControl element to the page and set its properties. You can find the full list of properties in the Properties article.

Example

ASP.NET

<telerik:RadSegmentedControl ID="RadSegmentedControl1" runat="server" LayoutMode="Compact" Size="Medium" SelectedValue="settings">
    <Items>
        <telerik:SegmentedControlItem Text="Home" Value="home" Icon="home" />
        <telerik:SegmentedControlItem Text="Settings" Value="settings" Icon="gear" />
        <telerik:SegmentedControlItem Text="Profile" Value="profile" Icon="user" Enabled="false" />
    </Items>
</telerik:RadSegmentedControl>

Creating the SegmentedControl Dynamically

To create the SegmentedControl on the server, create a new instance of the RadSegmentedControl object, set its properties, and add it to the Controls collection of another control (e.g. a PlaceHolder).

You can find the properties and enums in the following articles:

• Properties
• Enums

Example

ASP.NET

<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>

C#

protected void Page_Init(object sender, EventArgs e)
{
    RadSegmentedControl segmentedControl = new RadSegmentedControl()
    {
        ID = "RadSegmentedControl1",
        SelectedValue = "settings",
        LayoutMode = SegmentedControlLayoutMode.Compact,
        Size = SegmentedControlSize.Medium
    };

    segmentedControl.Items.Add(new SegmentedControlItem() { Text = "Home", Value = "home", Icon = "home" });
    segmentedControl.Items.Add(new SegmentedControlItem() { Text = "Settings", Value = "settings", Icon = "gear" });
    segmentedControl.Items.Add(new SegmentedControlItem() { Text = "Profile", Value = "profile", Icon = "user", Enabled = false });

    PlaceHolder1.Controls.Add(segmentedControl);
}

VB

Protected Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs)
    Dim segmentedControl As RadSegmentedControl = New RadSegmentedControl() With {
        .ID = "RadSegmentedControl1",
        .SelectedValue = "settings",
        .LayoutMode = SegmentedControlLayoutMode.Compact,
        .Size = SegmentedControlSize.Medium
    }

    segmentedControl.Items.Add(New SegmentedControlItem() With { .Text = "Home", .Value = "home", .Icon = "home" })
    segmentedControl.Items.Add(New SegmentedControlItem() With { .Text = "Settings", .Value = "settings", .Icon = "gear" })
    segmentedControl.Items.Add(New SegmentedControlItem() With { .Text = "Profile", .Value = "profile", .Icon = "user", .Enabled = False })

    PlaceHolder1.Controls.Add(segmentedControl)
End Sub
