You can generate the javascript server side:

"<script type='text/javascript'>" + Textbox1.ClientID +
".focus();</script>";

Try this one:

document.getElementById("<%=TextBox1.ClientID%>").focus();

What I have done is insert some Javascript to set the value for the ID of
the control. I start with this static Javascript.

var controlId;

function setControlId(id)
{
controlId = id;
}

Then I use Page.ClientScript.RegisterClientScriptBlock to add this code...

string script = "setControlId('" + textbox1.ClientId + "');";

You can then have the client script wrapped automatically with the script
tags when it is registered. Then you just use the value for the controlId
in the rest of your Javascript.
