Hello I tried using your script but it didn't help me in terms of auto-submitting my button. The following code is the button that I currently have that passes some information onto an external shopping cart: ' class=product-title type=hidden> ' class=product-price type=hidden > And the following is the script that displays the external shopping cart on my page: Finally This is how I tried to implement my button with your given script: public void Page_Load(Object sender EventArgs e) { if (!this.IsStartupScriptRegistered(Startup)) { // Form the script to be registered at client side. String scriptString =  function DoClick() {; scriptString += showMessage2.innerHTML= ' '}; scriptString += function Page_Load(){ showMessage1.innerHTML=; scriptString += ' RegisterStartupScript Example '} scriptString += /; scriptString += script>; this.RegisterStartupScript(Startup scriptString); } } But all this does is Print/Write my Shopping Cart button on the page once your given script's button is pressed. I however wish to execute my button once i.e. your given script's button is pressed/or when an IF argument is TRUE So I don't want my button to behave as a Click Button but instead I want to figure out how to extract that code from the Shopping Cart button and execute it myself from within my C#. Hope this makes sense Thanks again I've been searching for this answer for long now

I know you have a liitle bit confusion try this very simple code separatly and I'm sure that you will understand the mechanism C# runat= server > public void Page_Load(Object sender EventArgs e) { if (! this .IsStartupScriptRegistered( Startup )) { // Form the script to be registered at client side. String scriptString =  function DoClick() { ; scriptString += showMessage2.innerHTML=' Welcome to Microsoft .NET! '} ; scriptString += function Page_Load(){ showMessage1.innerHTML= ; scriptString += ' RegisterStartupScript Example '} ; scriptString += / ; scriptString += script> ; this .RegisterStartupScript( Startup  scriptString); } } 20 leftmargin= 10 onload= Page_Load() > myForm runat= server > showMessage1 > button value= ClickMe onclick= DoClick() > showMessage2 >

Hi and thank you for the help.. I'm kind of a newbie so forgive me if I don't get things straight away.. so what I did now is I've put a (1) TOP of my page function PrintSomeWords(var param) { alert(param); } (2) then in public void CallPrintSomeWords(var param) { Page.RegisterStartupScript(SriptID CallPrintSomeWords(' + param.ToString() + '); ); } (3) After my IF statement (when it is TRUE) I'm calling the CallPrintSomeWords(); (4) Under Am I missing something? How exactly can I pass the values that my button would eitherwise do (these values are retrieved from my DB and passed on to the button using a Session Variable and having the value of the button written like this: value=' ' It also gives me a ' Newline in constant' error Page.RegisterStartupScript('SriptID' CallPrintSomeWords(' + param.ToString() + '); ); Thanks again!

You can do this I give you two senarios: Senario1: //Javascript function PrintSomeWords(var param) { alert(param); } //C sharp ASP.Net public void CallPrintSomeWords(var param) { Page.RegisterStartupScript ( SriptID   CallPrintSomeWords (' + param.ToString() + ');  ) ; } Senario 2: the same thing but using window.execScript( CallPrintSomeWords (' + param.ToString() + ')  JScript); instead of Page.RegisterStartupScript ( SriptID   CallPrintSomeWords (' + param.ToString() + ');  ) ;
