You can make use of RegisterStartupScript like
Dim current As ScriptManager = ScriptManager.GetCurrent(Me.Page) If current IsNot Nothing AndAlso current.IsInAsyncPostBack Then ScriptManager.RegisterStartupScript(Me, Me.GetType(), "__AddJS", ";function test() { alert('Test'); }", True) Else ClientScript.RegisterStartupScript(Me.GetType(), "__AddJS", function test() { alert('Test'); }", True) End If
Please mark as Answer if it helps u. Thanks!

you can use the ClientScriptManager (http://msdn.microsoft.com/en-us/library/system.web.ui.clientscriptmanager.aspx) introduced with ASP .Net 2.0 to register scripts from the code behind.

you need to use RegisterClientScriptBlock, try below codeString scriptText = ""; scriptText += "<script>alert('hello')</script>";
ClientScriptManager.RegisterClientScriptBlock(this.GetType(), "CounterScript", scriptText, true);Refer below link to know more:http://msdn.microsoft.com/en-us/library/3hc29e2a.aspx

sumitd:
ClientScriptManager.RegisterClientScriptBlock(this.GetType(), "CounterScript", scriptText, true);
But I want to bind that javascript function to button.
just like
((ImageButton)e.Item.FindControl("btnChangePassword")).Attributes.Add("onclick", "return addRow('" + Index + "','" + Login + "' );");
I want to create javascript function createTable in c# code and pass it to the button attribute.
just like
((ImageButton)e.Item.FindControl("btnChangePassword")).Attributes.Add("onclick", "createTable();");

Like this?
if ( e.Item.ItemIndex == 0 )
{
System.Text.StringBuilder javaScript = new System.Text.StringBuilder();
javaScript.Append("function yourJavaScriptFunction()\n");
javaScript.Append("{\n");
javaScript.Append("// code for function here...\n");
javaScript.Append("}\n");ClientScript.RegisterClientScriptBlock(GetType(), "YourJavaScriptFunctionScript", javaScript.ToString(), true);

Try this
String scriptText = "";
scriptText += "function addRow(index, login){";
scriptText += "alert(index); alert(login); ";
scriptText += "}";
ClientScriptManager.RegisterClientScriptBlock(this.GetType(),
"CounterScript", scriptText, true);
TextBox1.Attributes.Add("onkeyup", "DisplayCharCount()");
((ImageButton)e.Item.FindControl("btnChangePassword")).Attributes.Add("onclick", "return addRow('" + Index + "','" + Login + "' );");

If you check my first post on this, the msdn link tells the same thing which i have posted in my last post, i just customized it as per the user need.
As far as TextBox1 is concerned i missed to remove it. It should be
String scriptText = "";
scriptText += "function addRow(index, login){";
scriptText += "alert(index); alert(login); ";
scriptText += "}";
ClientScriptManager.RegisterClientScriptBlock(this.GetType(),
"CounterScript", scriptText, true);
((ImageButton)e.Item.FindControl("btnChangePassword")).Attributes.Add("onclick", "return addRow('" + Index + "','" + Login + "' );");
