Question

How do I have a javascript popup showing a string? I declared a string:

string myString;
myString = "hello world!";

protected void Button1_Click(object sender, EventArgs e)
{
    Page.ClientScript.RegisterStartupScript(Page.GetType(), "message",
        "window.alert('myString');", true);
}

But it shows myString instead of hello world!

Un oh you are using ‘mystring’ as a literal instead of using its Text value. Do it like this:

Page.ClientScript.RegisterStartupScript(Page.GetType(), 
             "message", 
             "window.alert("\'" + myString + "\'");",
             true);
