Hi,

   Don't want to call  confirm() on button click  or onclientclick but want to call conditionally. and get the value and then proceed. As mention in question.

     Is it posible through javascript only.

  Thanks .

Yes Confirm is a javascript function. You can call it from server side code too

protected void Page_Load(object sender, EventArgs e)
{
  string message = "Do you want to Submit?";
  System.Text.StringBuilder sb = new System.Text.StringBuilder();
  sb.Append("return confirm('");
  sb.Append(message);
  sb.Append("');");
ClientScript.RegisterOnSubmitStatement(this.GetType(), "alert", sb.ToString());

}

Hi,

   But his work same as onclientclick.  but need to call it conditionaly

   i.e if(x==y ){

  //then i need to call confirm() & get its value and then proceed.

}

You can still do

protected void Page_Load(object sender, EventArgs e)
{
if(x == 7)
{
  string message = "Do you want to Submit?";
  System.Text.StringBuilder sb = new System.Text.StringBuilder();
  sb.Append("return confirm('");
  sb.Append(message);
  sb.Append("');");
ClientScript.RegisterOnSubmitStatement(this.GetType(), "alert", sb.ToString());
 }
}
