Um, this might be a bit simplistic and i'm not understanding, but how are you persisting your questionGroup variable across postbacks. Unlike winforms, the questionGroup variable that you wrap with the public property will not automatically be persisted.
Also, and this is just nit-pickery, but public properties on aspx pages is not particularly good practice - particularly with the new 2005 project structure.
(BTW, seeing the current blacklist makes me really want to try and get on it... It's like an itch that i really shouldn't scratch...

Thanks for the reply... I should have added that this is .NET 1.1 not 2.0
I am not persisting the questionGroup variable, and I think this is at least part of the issue. I tried storing it in ViewState originally but I get an error saying that an object of that type needs to be marked as serializable or have a type converter defined...as the code (for a typed dataset) is autogen'd I cant add either of these!
As for the nit-picky-ness that property was supposed to be protected, and is there for syntactic sugar - its not part of any real functionality.
As for the blacklist, feel free to be rude, abusive or insulting and you'll be added in a second  The downside is that I answer about 100x more questions here than I ask. (in fact this is the first time I ever remember asking a question and I have about 800 posts!) A position on the list ensures I never answer your questions!

That's going to cause you problems - you'll need to either store the dataset somewhere or rebuild it on every postback. I've never worked much with typed datasets, so i don't know about marking it serializable, but it's kinda funny, as an ordinary DS is serializable by default...
And i think i'll just stay itchy in that case...

Hi there,
Do you get the error on postback? If this is the case, IMO there are two options that you may consider:
+ Persist the length of the QuestionGroupRow object instead of the object itself in the ViewState so that when the page posts back you can re-create the control hierarchy in the user control.
+ Disable the ViewState of the repeater control, and bind the datasource to the repeater every time the page is visited.

Hello,
Is there any way to get specific records from XML file using ASP.Net with VB.Net?
There are two XML files one for categories and other for products. I want to get products against specific category.
Or can we use "Select Query" in XML files?
If you know the solution then please let me know.
Bye,

How are the two files linked?
Xml forum might be a better place to ask...

Does anyone have any info on whether it is possible to modify postback info client side? I have added some javascript functions for ordering a select (listbox) control but cannot sucessfully change the postback to reflect these changes.
Is Ajax the only way to go? I'd rather not have to create pages to process the data if possible, I just want to persist the changes!

Maybe I'm just slow this morning but I'm not sure what you mean. Do you need to select a new item in the listbox and have it update a datagrid(or other control) immediately? If so you can either use Ajax (I'm not sure how to implement yet) or you can make the listbox a server side web control and tell it to postback (using AutoPostBack) on item changed.

I think what's being asked for is a way to postback to the server changes made to the order of items in a listbox via client-sode Javascript.
One way is to include an asp:Textbox with Viasible=False (this renders on the page as input type="hidden") - you can then use your JS functions to update the value of this with the values of your listitems when re-ordered (seperated by commas, maybe) and this will then be sent to the server on a PostBack, where you can read in and parse the textbox.text to get the new order.
Hope that helps

Actually, of course, it doesn't have to be an asp;Textbox Visible=false - it can be an ordinary input type="hidden" field, and it's value can be read on PostBack by a simple Request call...

There is no substitute to actually understanding the subject - it will also help you should you actually get the job!

You can simply use:
TextBox.Text.SubString ( TextBox.Text.IndexOf ( "@" ) + 1 )

What is the page you are trying to browse to doing?
Is the message an IIS message or a .net message?

Hello,
I have a HTML select control.(i.e listbox).
Now I want to add values dynamically to this control.How can I do that.I don't want to maek it runat=server.I want it to be a html client control only.
|
|
|
|

Interesting question !
According to any test books I have you can't do this. You must supply runat=server in order to access HTML controls (thus turning them into Html server controls) for with the code behind files.
You could pass parameters to JavaScript and let JavaScript use Document Object model to do this. But why bother wht you can simply use runat=server.
Look where you want to go not where you don't want to crash.

Then you only can use Javascript to add items to it.
Use doucment.createElement to create an option element, set it's properties and add it to the options collection of the select control.
