Using Page.ClientScript.RegisterStartupScript.

C#

Page.ClientScript.RegisterStartupScript(this.GetType(), "MyScript",
   "javascript:TestJavascriptFunction();", true);

I have registered my button on page load function like this :
Button1.Attributes.Add("onclick", "alert('Error')");

But i dont want this attribute to execute all the time whenever i press the Button1, instead i have a condition inside the Button1_click depending on the condition i need to show the alert, so my concern is how to call this statement() inside my if condition.
Code snippt :
public void btn_ProjWiseRevCost_Click(System.Object sender, System.EventArgs e)
{
int a=1;
if( a == 0)
{
// Call that alert
}
}

Please someone help me.

if( a == 0)
      {
         Page.ClientScript.RegisterStartupScript(this.GetType(), "MyScript",
   "javascript:alert('Error');", true);
       }
