Reset to default 15Perhaps you are looking for RegisterStartupScript:
ScriptManager.RegisterStartupScript(Me, Page.GetType, "Script", "showDisplay();", True)
Depending on where your showDisplay() javascript function exists in your code, using RegisterClientScriptBlock may not find it. This is because RegisterClientScriptBlock places the javascript at the top of your page, immediately after the viewstate. Using RegisterStartupScript will place the call to showDisplay() at the very bottom of your form, so it will be rendered last and your javascript function will have already been rendered and available.
