Write this in PageLoad (the only modifications from what you were writing are the moment in time of the registration -- PageLoad not Click, Click is too late and the face that you must write the actual implementation of the javascript function here):

    protected void Page_Load(object sender, EventArgs e) {
        ScriptManager.RegisterStartupScript(this, this.GetType(), "myscript", 
@"function doSomeThing() {
    alert(""TestReady"");
}"
        , true);
    }

and this in the asp:LinkButton tag (you must specify the OnClientClick attribute):

<asp:LinkButton ID="vidoUpdatebtn" runat="server" OnClick="vidoUpdatebtn_Click" OnClientClick="doSomeThing()" >LinkButton</asp:LinkButton>

And it should work.

If you want client side code to run on the button click, you could use the OnClickClick property instead of the OnClick event. That'll also avoid the need for a postback and will give immediate feedback to the user.

e.g.

<asp:LinkButton ID="vidoUpdatebtn" OnClientClick="alert('TestReady'); return false;" runat="server">LinkButton</asp:LinkButton>

Have you tried this way:

Add Script manager on your aspx page

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" />

Codebehind:

Page.ClientScript.RegisterStartupScript(this.GetType(),"myscript", "doSomeThing()",true);
