ASP.Net Message Box Alert Display

Aug 20, 2009 02:38 PM|LINK

I am new to ASP.Net and really need to know how can one display an Alert in a webpage. I know that Adobe Flex and the Javascript offer controls to display the Alert but have no idea of this being present in the ASP.Net

So if anyone can provide the control or a technique to display an alert it would really be helpful

JavaScript is JavaScript - all these frameworks do is offer you different ways of putting the alert('message'); on the page. You can either write an alert straight to your page

<script type="text/JavaScript">
alert('hello world');

</script>

You can use the ASP.NET codebehind to write it to the page

ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + myStringVariable + "');", true);

You can also response.write it to the page as shown earlier, you can also write the javascript to a literal on the page.

Not interested in your tweets since 1981.

Hi moonlight007,

From your description, you want to display the messagebox in the page.

You can use the javascript alert or confirm function for this requirement.

Of course, you can display a div for message box by the div tag display property.

By the way, I recommend you use the JQuery plugin for showing the messagebox.

Hi,

There are two scenerios, either you want to display message while staying on clientside or you want to display message from server side i.e. after page postback.

In any case, alert() of JScript is the only option to display a meassge box. You can invoke any javascript function from code behind as guided in other replies.

Moreover, Asp.Net do provide a wide range of Validation Controls to validate web form input. There exists a property ' ShowMessageBox ' in ValidationSummary control, that, if set to true, would display an alert box against a wrong input. To see how to use it, visit Display Message Box Against Wrong Input.

Another weird approach is to just import System.Windows.Forms namespace and start using MessageBox.Show().

Don't forget to Mark this as an Answer, if it helps

Thank you

You could try using this method, maybe it can help you
```
private void ShowPopUpMsg(string msg)
    {
        StringBuilder sb = new StringBuilder();
        sb.Append("alert('");
        sb.Append(msg.Replace("\n", "\\n").Replace("\r", "").Replace("'", "\\'"));
        sb.Append("');");
        ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "showalert", sb.ToString(), true);
    }
```
