View 1 RepliesI'm using a GridView control, using the Northwind database as a sandbox.
I have allowed editing of rows using AutoGenerateEditButton="true" and that all works fine. The book I'm using for reference the following code behind for error handling (C#):

However, this seems to have no effect upon my label text, leading me to believe that the exception handling snippet won't work either.
I've installed Visual Web Developer 2010 Express on a Windows XP Pro PC. IIS is NOT installed yet. I am just evaluating this now, and the built in web server works fine for now.
I've followed these very basic steps and I'm stuck with this error:
Error WebForm_PostBackOptions is undefined
I am trying to add a RequiredFieldsValidator control to the page. Here are the steps I followed...
1- Menu options: File -> New Web Site
2- ASP.NET Empty Web Site
3- Website -> Add new item
4- Select Web Form with Place Code in separate file checked. Master page not checked.
5- No changes to the web.config file
6- I added a couple text boxes and labels to the page and a button.
7- If I click the button now, no problem. The page submits and is displayed with the information entered in the text box fields.
8- Add a RequiredFieldsValidator next to the first text box.
9- I set the ErrorMessage to some text
10- I set the ControlToValidate to the first text box's ID
11- I save then run with CTL + F5
12- The page is displayed in IE 7. I hit the Submit button and I get the popup error described above.
I used the Web Platform Installer for the installation. Everything went fine. All other aspects of my development and testing have been fine. This is the first major roadblock I hit. I think it has something to do with a configuration setting in the web.config file, but I do not know what setting to add/change.
Not point to the break point.it gives above error massege when start debbuging. How i fix this.

View 2 RepliesI am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
I am using this signature control. Here's the web.forms code...
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="KahunaCentralTIDRevamp.SignatureCapture.Index" %> [code]....

What is right way to send visitors from one webform to other. What are their limitations and their plus points.
View 2 RepliesJust wondering, in an ASP.NET MVC3 environnement with entity framework. Should the Unit of Work point to the service layer or the repository (and then the repository point to the service layer) ?
Ive saw two example:
* One where the unit of work and repository both have an instance to the service layer..
Link: Entity Framework 4 CTP 4 / CTP 5 Generic Repository Pattern and Unit Testable
Doesn't use a service layer but its obvious that one could be use in that case.
* Second where the unit of work have an instance to the repository which have an instance to the service layer..

What would be better ?
I am looking for a control that can draw a very customized chart in ASP.NET. The chart comprises:
1. A closed triangle, or polygon, shaded, drawn according to a fixed set of xy vertices.
2. A series of x,y points plotted on top of the triangle or polygon.
I thought the chart Control wasthe best, but I can't figure out how to draw the close triangle or polygon.
Is GDI+ the better way?

I would like to know if there is any way to draw some dynamic number of points and lines in a report.
I will have a group of "coordinates" that will define where in the report I must draw the items (cm from the left, and cm from the top).
Is there any way to achieve that? I can draw fixed elements, but I want positioning them dynamically.
The final target is to draw a map which mantains a scale, and draw some relevant elements in the map.
I'm thinking to have a datasource with all the location, the appearance and text data, and then (still don't know how) draw each element with it's style.

View 1 RepliesOkay, so this is one of those annoying bugs that happens sometimes, but not with enough regularity to really root out.
Fair warning that I'm still just toddling in ASP.NET, so I could be doing something heartbreakingly stupid. Here's the gist:
I've got a page with the bulk of its content inside of a TabContainer from the AJAX Toolkit. There are a few page elements outside the TabContainer -- mostly just header/footer stuff from the master page. Sometimes the page will load (either initially or on a postback) and the TabContainer will completely fail to draw, leaving a mostly-empty page. Clicking "Reload" in the browser almost always makes everything appear as usual.
What would make a TabContainer occasionally fail to draw? How can I go about debugging this.
Anyone have good example of how to write text onto a jpg image and resave it using System.Drawing in .NET?
View 3 RepliesI am using the following code to draw text onto a jpg image but it requires x/y coordinate percision on where to place the text.
[code]....
How would I go about centering text onto an image? I am guessing it would have to do with defining some sort of container (rectangle maybe?) that is the width of the image and centering the text within that? Not sure what the best practice would be for this.
I'm currently programming an application in ASP.net MVC and I'm looking for a plug-in or anything that will to draw some rectangles and manage them. The rectangles should be resizable, movable and they should be compose of 8 points (at the middle of each corner and at each corner). I already found SVG, HTML 5(canvas) and [URL].
