I have a Radio button in a Gridview and when we click on the button, i'm calling function in the code behind file(user control). Before that i need to implement need call a javascript function to confirm about change. I tried onclick, OnClientClick, OnSelect and none of them worked as expected.

<asp:RadioButton ID="ratiobuttonChoose" runat="server" AutoPostBack="true" 
                                    OnCheckedChanged="Selected"/>

Can someone, please suggest me how to do this one.

Add a script on Page_Load in code behind:

ratiobuttonChoose.Attributes.Add("onclick", "clientJsFunction()");

Reference: MSDN

You can add onclick direct on your tag (VisualStudio don't suggest but it works):

<asp:RadioButton ID="ratiobuttonChoose" runat="server" AutoPostBack="true" 
    OnCheckedChanged="Selected" onclick="alert('Clicked!');" />

You can also use jQuery, see here.
