Doubts using Ext.MessageBox - Ext JS

#2 03-01-2007, 09:28 PM

Using alpha2 rev6, I'm unable to reproduce this problem. Which one are you using?

Yes I am using alpha2 rev6, when I get a error from server (asp.net) it response with an aspx page, in my case I get the error from server in resp.responseText, it appear in the Ext.MessageBox.alert with yellow color in error ect.. like appear in an aspx page with error, but it has many text and disapear the close button, I would like show the error inside textArea in a multi-line prompt dialog, becouse it have scroll bar but I don't know how set the resp.responseText to textArea inside multi-line prompt dialog, I like the alert becouse it show the resp.responseText with color (like a html page), but don't have scroll bar and only has a button OK. Is there some dialog where I can show the error with scroll, and add for instance a button to send error for mail I mean (show the error and appear Send Error button)?

kind regards
Frank

Setting HTML inside a textarea will have the effect that the HTML is not shown rendered anymore. You better put the ASP error inside a div element, and then set the css property overflow:auto, so it will have a scrollbar.

Could you post a screenshot BTW, your description of the problem is very unclear.

Well, I guess the question then, is how much text are you getting back? Can that text be paired down to the bare essentials? And, is that text an entire HTML document with doctype, html tag, head tag, body tag, etc? If so, that's just not going to work like you want it to. In order to include it in the dialog, it must be an HTML fragment, not a complete HTML document.

more clear , I am doing it:

I send a xml to server, I parsed it and update the database, if there is an error in this proccess I catch the exception and send it to client, then I want to show it to user, but if I try with alert the exception from server has many information and the button close in the dialog go up and don't appear in the browse, so the doubt can I use some Ext.MessageBox dialog to show the client or I have to do my dialog?

using a multi-line prompt dialog the error don't appear in html format but i can read it using scroll how I can add the error to textArea in multi-line prompt dialog?

example the a exception send from server

<html><head><title>Object reference not set to an instance of an object.</title>

<style>
body {font-family:"Verdana";font-weight:normal;font-size: .7em;color:black;}
p {font-family:"Verdana";font-weight:normal;color:black;margin-top: -5px}
b {font-family:"Verdana";font-weight:bold;color:black;margin-top: -5px}
H1 { font-family:"Verdana";font-weight:normal;font-size:18pt;color:red }
H2 { font-family:"Verdana";font-weight:normal;font-size:14pt;color:maroon }
pre {font-family:"Lucida Console";font-size: .9em}
.marker {font-weight: bold; color: black;text-decoration: none;}
.version {color: gray;}
.error {margin-bottom: 10px;}
.expandable { text-decoration:underline; font-weight:bold; color:navy; cursor:hand; }
</style></head><body bgcolor="white">

If you are getting back a full HTML page as the response, try displaying it in an iframe. If you inject XML containing an HTML element into a subelement of your page it can really confuse your browser.

Alright franklt69, I need you to go back and reread my previous reply. I specifically said that you weren't going to get things to work properly if you are injecting HTML that contains a doctype, html tag, head tag, or body tag into your dialog.

Rather than an alert, you're going to have to take that build a basic dialog with an iframe, take the response from the server, and inject that into the iframe's DOM.

What might be easier is trimming down the response the server sends to something that's just an HTML fragment.

Hi I need some help about how inject html into a Iframe

when in the server (asp.net) there is an error it response with a html like the code post above, then I am doing it

function responseFailure(resp){

showError(resp.responseText);

}

showError: function(aError){
if(!dlgError){ // lazy initialize the dialog and only create it once
dlgError = new Ext.LayoutDialog("dlg-error", {
modal:true,
width:800,
height:400,
shadow:true,
minWidth:300,
minHeight:300,
proxyDrag:true,
title: 'Error Windows',
shadow:true,
center:{alwaysShowTabs:true},
north: {
split:false,
initialSize: 25

},

center: {
autoScroll:true,
tabPosition: 'top',
closeOnTab: true,
alwaysShowTabs: false
}
});
dlgError.addKeyListener(27, dlgError.hide, dlgError);
dlgError.addButton('Send', dlgError.hide, dlgError);
dlgError.addButton('Dont Send', dlgError.hide, dlgError);

var layout = dlgError.getLayout();
dlgError.beginUpdate();
debugger;
var iframe = Ext.DomHelper.append(document.body,
{tag: 'iframe', frameBorder: 0});
iframe.innerHTML = aError;
feedPanel = new Ext.ContentPanel(iframe, {fitToFrame:true, autoScroll:true, closable:false});
layout.add('center', feedPanel);
dlgError.endUpdate();
}

dlgError.show();
}

the doubt is how I can inject the html (aError) into an iframe ?

kind regards
Frank

Why are you allowing the server exception to just dump back to a generic error page? You should catch the exception in your aspx page and build a simple reponse string from the exception properties (e.g. Message, Stacktrace, InnerException, etc). Then pass that back without all the html and use that as the content of your dialog body. The way you're doing it now, it appears that the error is not being caught and just output via the standard .Net error page.
