Tried the following and able to see the result as needed body onload = MyFunction(); > form id = form1 runat = server > asp:ScriptManager ID = scriptmgr runat = server > asp:ScriptManager > div > asp:TextBox ID = txtLanguage runat = server Text = Hindi > asp:TextBox > asp:TextBox ID = txtSelectedLanguage runat = server > asp:TextBox > div > form > script type = text/javascript > function MyFunction() { var hiddenvalue = document .getElementById( %= txtLanguage.ClientID % > ).value; if ( hiddenvalue == 'Hindi') { document.getElementById(txtSelectedLanguage) .innerText = HindiText ; } else { //english text } } script > body > If you want the same try this in page_load ClientScript.RegisterStartupScript(GetType() MyFunction  MyFunction();  true );

You need to use the following ClientScript.RegisterStartupScript(GetType() MyFunction  MyFunction();  true ); instead of ScriptManager.RegisterClientScriptBlock( this .Page this .GetType() MyFunction  MyFunction();  true );

Hi Hari why are u doing this way if you have two or more condition then save the data in hidden filed and get data in javaScript and change the condition as per requirement.

Any script errors you are getting? In the code you posted I could see a closing brace is missing
