Hi, I have a string builder which does the following,

 StringBuilder sb = new StringBuilder();

 sb.AppendLine("-Agency name cannot be empty");

sb.AppendLine("-Phone cannot be empty"); 

now i also have this,

ScriptManager.RegisterStartupScript(this.UpdatePanel1, typeof(string), "script", "alert('" + sb.ToString()+ "');", true); 

 but i have the error, "unterminated string constant stringbuilder"

any idea what to do? to get rid of this..

Thanks,
 

since the string you're building will become a piece of javascript, you would want to avoid AppendLine which appends a crlf and use \n wherever you want a newline

sb.Append("-Agency name cannot be empty\n");

sb.Append("-Phone cannot be empty\n"); 

nope..i couldn't get it work...

i think i forgot to mention the textbox and the button is wrapped inside an ajax update panel too..

help pls? 

As Mike posted the only time that I get an Unterminated string constant error is when I use sb.AppendLine. If you use sb.Append("-Agency name cannot be empty\n") you will have the same problem. This, however, worked with no problems.
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("-Agency name cannot be empty\\n");
sb.Append("-Phone cannot be empty\\n");

ScriptManager.RegisterStartupScript(this.UpdatePanel1, typeof(string), "script", "alert('" + sb.ToString()+ "');", true);
