add something like this

System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("if (typeof(Page_ClientValidate) == 'function') { ");
sb.Append("if (Page_ClientValidate() == false) { return false; }} ");
sb.Append("this.value = 'Wait...';");
sb.Append("this.disabled = true;");
sb.Append(this.Page.GetPostBackEventReference(this.<buttonname>));
sb.Append(";");
this.<buttonname>.Attributes.Add("onclick", sb.ToString());

remeber to change <buttonname> to the actual name of u're button.
