Radio Button not firing itemcommand event in repeater - asp.net

Question

I am working on the asp.net custom control in which I am using repeater control to show radio buttons.
I need to fire repeaters ItemCommand event when RadioButton is click.
The problem I faced is RadioButton is not capabel of firing ItemCommend event and it does not have CommendArgument, and CommandName properties.
To accomplish I created asp.net server control, drived i from RadioButton and add CommendArgument, and CommandName properties in it.
I also added a Button in it so that I can call the click event of this button programatically to fire repeaters ItemCommand event.
Now the problem I am facing is I have fired Button's click event but still ItemCommand event is not firing.
Any idea how to gat this thind done?

You can call the repeaters ItemCommand event when the OnCheckedChanged of the radio button is fired.
I think the main problem is you're not sure how to create the arguments expected by ItemCommand, here's an example which I believe will help:
ASPX:
<asp:Repeater ID="rptColors" runat="server" onitemcommand="rptColors_ItemCommand">
<ItemTemplate>
<asp:RadioButton ID="rdbColour" Text='<%# Eval("Color") %>' AutoPostBack="true" runat="server" OnCheckedChanged="Checked" /> <br />
</ItemTemplate>
</asp:Repeater>
Code behind:
public class Colours
{
public string Color { get; set; }
}
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
rptColors.DataSource = new List<Colours> { new Colours { Color = "Red" }, new Colours { Color = "Black" } };
rptColors.DataBind();
}
}
protected void Checked(object sender, EventArgs e)
{
foreach (RepeaterItem item in rptColors.Items)
{
RadioButton rdbColour = item.FindControl("rdbColour") as RadioButton;
if (rdbColour.Text.Equals((sender as RadioButton).Text))
{
CommandEventArgs commandArgs = new CommandEventArgs("SomeCommand", rdbColour.Text);
RepeaterCommandEventArgs repeaterArgs = new RepeaterCommandEventArgs(item, rdbColour, commandArgs);
rptColors_ItemCommand(rdbColour, repeaterArgs);
}
}
}
protected void rptColors_ItemCommand(object source, RepeaterCommandEventArgs e)
{
//Runs when you select the radio button in the repeater
System.Diagnostics.Debugger.Break();
}
}
