    EXT.net.dll in VS2010

    Hi,
    I am new to coolite, and we are a team of 7 assigned to test ERP applications with HTML5 and mvc, and extjs library, we try to use coolite, but can never add tags like <Items><content><canvas> etc inside panels...only that <body> tag which not a good HTML code, always getting the error Can not be a public property tag...

    What is it that we should do to get EXT.NET.DLL to work properly?
    and what is the proper way/ways to structure the HTML in coolite?

    Thanks a million in advance.

    Hi amexus,

    I tried the following sample with a <canvas> script and it appears to work correctly.

    Example

    Code:
    <%@ Page Language="C#" %>
    
    <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
    
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
    	<title>Canvas Test</title>
        
        <ext:ResourcePlaceHolder runat="server" />  
    	
    	<!--[if IE]><script src="excanvas.js"></script><![endif]--> 
    	<script type="text/javascript">
    	    Ext.onReady(function () {
    			var drawingCanvas = document.getElementById('myDrawing');
    			
    			// Check the element is in the DOM and the browser supports canvas
    			if (drawingCanvas && drawingCanvas.getContext) {
    				// Initaliase a 2-dimensional drawing context
    				var context = drawingCanvas.getContext('2d');
    				
    				// Create the yellow face
    				context.strokeStyle = "#000000";
    				context.fillStyle = "#FFFF00";
    				context.beginPath();
    				context.arc(100,100,50,0,Math.PI*2,true);
    				context.closePath();
    				context.stroke();
    				context.fill();
    				
    				// Add 2 green eyes					
    				context.strokeStyle = "#000000";
    				context.fillStyle = "#FFFFFF";
    				context.beginPath();
    				context.arc(80,80,8,0,Math.PI*2,true);
    				context.closePath();
    				context.stroke();
    				context.fill();
    				
    				context.fillStyle = "#009966";
    				context.beginPath();
    				context.arc(80,80,5,0,Math.PI*2,true);
    				context.closePath();
    				context.fill();
    				
    				context.strokeStyle = "#000000";
    				context.fillStyle = "#FFFFFF";
    				context.beginPath();
    				context.arc(120,80,8,0,Math.PI*2,true);
    				context.closePath();
    				context.stroke();
    				context.fill();
    				
    				context.fillStyle = "#009966";
    				context.beginPath();
    				context.arc(120,80,5,0,Math.PI*2,true);
    				context.closePath();
    				context.fill();
    				
    				// Create the diamond-shaped nose
    				context.fillStyle = "#000000";
    				context.beginPath();
    				context.moveTo(93,100);
    				context.lineTo(100,93);
    				context.lineTo(107,100);
    				context.lineTo(100,107);
    				context.closePath();
    				context.fill();

    				context.stroke();
    			}
    		});
    	</script>

                Title="Hello Canvas World" 
                Height="210" 
                Width="210">
                <Content>

    Hope this helps.

    I should also mention, the <canvas> sample came from the following "How to Draw with HTML 5 Canvas" blog post, see

    http://thinkvitamin.com/dev/html-5-d...html-5-canvas/

    Hope this helps.

    Thanks very Much for the example and the resources, I have tried them in a standalone project and it works fine, yet when using MVC in vs2010, we get errors, so my guess is it is a problem in setting up the environment, is there like a resource or guidleines for how things should be in vs2010, I have read many posts about it but not much in terms of solutions.

    again thanks a lot, really appreciate your effort.

    Hi amexus,

    Does even the simplest of Ext.NET pages/views render? say, a page with just a ResourceManager and Window?
