fire javascript function from asp.net codebehind

Question

This is my javascript function ,

 function returnToParent() {            
        var oArg = new Object();
        var oWnd = GetRadWindow();
        oArg.ReturnValue = "Submit";
        oWnd.close(oArg);
    }

And this is how I call this function on client side

 <button title="Submit" runat="server" id="close" onclick="returnToParent(); return false;">
                    OK</button>

I want to fire this function in server side button click event .
What I've done is add new button

 <asp:Button runat="server" ID="rtxtSubmitChange" OnClick="rtxtSubmitChange_Click"  Text="Submit" />

and in ButtonClick Event ,

protected void rtxtSubmitChange_Click(object sender, EventArgs e)
    {
        Page.ClientScript.RegisterStartupScript(GetType(),
"MyKey",
"returnToParent();",
false);
    }

But It doesn't work . What I am wrong in my code ?

I'm surprised you managed to compile this. OnClick is to be handled on the server side (C#), and OnClientClick on the client (Javascript). So, besides fixing your markup, you should call the Javascript function from the server side just if there's something you need to do before doing so. Otherwise, just use the OnClientClick. — emerson.marini

Please check if javascript file containing function is available. If so check if function is available or not. Sometimes js files are cached & new functions definitions thus are not available — Pranav Singh

Page.ClientScript is deprecated. Use ClientScriptManager instead. But if you're playing with UpdatePanels, use ScriptManager instead. Also, when you stick a breakpoint on the click handler, does it get hit? — emerson.marini

Try

ScriptManager.RegisterStartupScript(this, this.GetType(), this.ClientID, "returnToParent()", true);

OR

ScriptManager.RegisterStartupScript(Page, Page.GetType(), this.ClientID, "returnToParent()", true);

For more details refer :ScriptManager.RegisterStartupScript Method
