Where is the best part of asp.net page or code behind to register RegisterClientScriptBlock.

You have a bunch of options.
Register script includes in your <head> section or do inline <script> tags. I prefer to have my scripts at the bottom of the page though.
You can also register it at the Page level in your Page_Load (or any other event) by calling ClientScript.RegisterClientScriptBlock and passing it the script you want. Remember that if you do go with RegisterClientScriptBlock, you will need to make sure that you register the code with every page load so that is why I would recommend the Page_Load event if you want to use this method.
For example:
protected void Page_Load(object sender, EventArgs e)
{
AddClientSideJavascript();
// Do other stuff
}
private void AddClientSideJavascript()
{
// Register some client script code
Type someType = this.GetType();
if (!ClientScript.IsClientScriptBlockRegistered(someType, "TESTSCRIPT"))
{
string script = "function ShowAlert() { alert('Test'); }";
ClientScript.RegisterClientScriptBlock(someType, "TESTSCRIPT", script, true);
}
// Register more here... etc...
}
Just make sure you don't include it the portion of your Page_Load that is wrapped with the if (!IsPostBack) check or else your scripts will not get registered after any postbacks.
