Web Forms

Hi,

I have just started to work through Chapter 17 - Web Forms.

Will the fact that I'm currently running Internet Explorer Version 7 effect the exercises in this chapter? I'm doing the first 'Try it out' in the chapter, and after having added and positioned my 4 controls as directed, what I see in my browser bares no resemblance whatsoever to Figure 17-4. It looks a mess to be quite honest!

Any suggestions?

Many thanks!

Keith

This problem appears to have cured itself....don't ask me how?? Before, the buttons appeared stretched from one edge of the browser to the other. Weird!

I am however still experiencing issues with this 'Try it out', mainly around differences between what the book says should be happening, and what is actually happening.

Firstly, upon setting up the project, the files in my solution explorer included the web.config file, where as Figure 17-3 does not.

Secondly, when trying to apply code to the OnClick event of the btnClient, it tells me to first set the DefaultClientScript property to VBScript by selecting DOCUMENT from the combo box of the Properties Explorer. I did this, but there was no DefaultClientScript property to be seen. I had to physically change it in the HTML source code.

Finally, my HTML source code did not include a meta object inside the head element.

Any reason for these differences? Am I doing something wrong?

Many thanks!

I seem to be having immense difficulty with this chapter, and I'd be grateful if someone who's done it could give me some pointers as to what could be going on.

In addition to the issues in my previous posts, I'm now doing Step 7 of the Try It Out on page 568. It tells me to define the master page layout by double clicking on the file in the root directory and update the code where highlighted. If it were a case that all I had to do was update the highlighted code, then I'd be fine, but on my version of the application, I'm having to type out all the code on the following page as well! Is this right?? Shouldn't all this code have been generated automatically, or am I honestly expected to type the whole lot!?

I'd really be grateful for any help.

Many thanks!

Hi Keith,

About defaultclientscript.

That has been an issue since the Beta version went to the release. I never figured out if that is a bug or what in Visual Studio. TO work around the issue you can switch to source view on the default.aspx page. That is at the bottom left of the design area. In between the start and end <head> tags put the following

<meta content="text/VBScript" http-equiv="content-script-type" />

Then when you create your client script it will default to vbscript. That is what selecting the defaultclientscript would do for you.

Here is more info from MSDN2

http://msdn2.microsoft.com/en-us/library/5y06x9d7.aspx

Aslo, in Chapter 17 there is another issue on page 576.

You will need to set OldValuesParameterFormatString proterty to "original_{0}" for the asp:SqlDataSource control. Otherwise, you might get an issue about declaring @original_au_id.

Let me knos how you are doing and I will try to help you with your any other issues you are still having.

Hi Bryan,

Many thanks for getting back to me!

For the DefaultClientScript property, I ended up doing what you have illustrated anyway. That's not so much of an issue any more.

The main issue now, and what has stopped me in my tracks, is page 568. In my application, I'm having to type out pretty much all the code on both pages, rather than just the highlighted code shown in the book. The impression I get from the book is that all this code should have been there already.

Kind regards,

Keith

I think the highlighted code is a little misleading on that page. You will have to either download the code from the wrox site or type it in. You will get better typing it in and it will not be a big issue later as you or coding on your instead of trying to copy from the book.

I'm still having trouble with this. After typing out all the code on page 569, I am getting the following errors:

First, the DOCTYPE element in my code states the following (note bold text): "-//W3C//DTD XHTML 1.0 Transitional//EN". In the book: "-//W3C//DTD XHTML 1.1//EN".
The 'style' element is missing the required attribute 'type' in my application and underlined red.
The attribute 'bgcolor' in my application is considered outdated and underlined green.
Element 'MenuItem' is an unknown element in my application and underlined red.
The 'height' attribute is not a valid attribute of the 'table' element in my application and underlined red.

It is probably so blindingly obvious to a lot of people on here what the issue may be, but I'm a complete novice to Web Forms. I have followed the book to the letter to this point, and it gives no mention or warning that the above errors will/can occur.

It's a shame, since the book has been superb up to this point and I've learnt a hell of a lot, but this chapter has been a total nightmare!

Hi Keith,

Sorry for the delay getting back to you. Can you post your code or email it to me so I can help you. If you click the email poster image in one of my posts you can just email a zipped copy of your project or just the one page zipped up. I cannot receive .aspx ro .vb attachments. Give me a day or two to respond and I should be able to figure this out for you.

Thanks,

Bryan
