try catch question

I have an items presenter that contains expanders.  (In order to debug the events, I have a custom items presenter class with an OnChildDesiredSizeChanged event that does nothing more than base.OnChildDesiredEvent.  That way I can debug what I am really working on.

I have a custom expander class that I want to have change its desired size when it is collapsed.  The frustrating thing about expander is that they will update a desired size when you expand, but not when you collapse it.  So I have a custom expander class with my own on collapse event.  The idea is to remeasure the expander.  I had thought that doing so would cause it to notify parents that its desired size changed like what already happens when we expand.

So here is the collapse handler in my custom expander.

protected override void OnCollapsed()
		{
			UIElement hdr = Header as UIElement;
			if (hdr != null)
			{
				InvalidateMeasure();
				Measure(hdr.RenderSize);
				
			}
		}

Debugging I can see the desired size get smaller before and after I call measure.  So my desired size propert

1. In regular asp net I can run (debug) the application but I can either "view in browser" that gives me the option to view the application and write code on same time.

In MVC I can't find this option.

I watch some of the MVC video, seems that the music store is good but I have to wait to the other part.

Does any one know and recommend   a Microsoft MVC tutorial?

I've been building web sites and for my next project I will be creating a web application.  I use a 'BasePage' class in all my projects but, since web applications do not contain the 'App_Code' folder, what is the best place/practice for the 'BasePage' class?

Thanks,

TML

when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

I know there is a method built in for retrieving the encrypted password, but how do I retrieve the encrypted security answer?

What I want to do is have a member profile update screen that the end user can update their password and security question and answer. However, when they get to this page, I want to already be showing the security question (the easy part) and its answer (the not so easy part).

I have updated web.config with passwordFormat=Encrypted and have added a machineKey with the generator (forgot the link, but located on eggheadcafe somewhere).

I haven't done ANYTHING yet, since I already have a user store with hashed information. I wanted to get some functionality done before publishing, wiping the store and recreating users (only a couple developers).

Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!

I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).

Appreciate any help I can get!

Thankyou!

Hi Everyone,

I have a strange problem:

There is an entity (Table) called "Filters" in my .edmx which has all my tables and stuff in it (to use it for LINQ queries)

I have created a class called "CustomFilters" which inherits "Filters". So now my cutom class has all the properties of the original "Filters" class (table) and 1 more additional property that i wanted which is a List of "CustomFilters":

List<CustomFilters> children = new List<CustomFilters>();

Now i get all my records into:

List<CustomFilters> theOriginalList = new List<CustomFilters>();

NOTE: first all records are tken into a List<Filters> and then these are added into List<CustomFilters> where List<CustomFilters> for children of that record is added, and then children of the child records, and so on......

so now, every record is an instance of CustomFilters which has a property named "children" which is a list again; and each child again has instanaces of "CustomFilters", and each instance again has children...and on and on and on.....

(basiacally its a data source for a treeview in my silverlight control)

every thing is good and working as expected.

but:

hi,

would any body please help me to catch the exception if the column doesnot exist as my table columns are not static.

sometimes its throwing me indexoutofrange exception as the column doesnot exist

thanks for the help guys

Hello,

I'm currently getting to know the linqdatasource control. What would happen if several WHERE parameters are added to the linqdatasource control declaritively in the aspx page but no WHERE clause is defined? 

1. is there any issue with setting up multiple WHERE parameters in the aspx markup for linqdatasource but then deciding which ones actually get used at runtime by setting the actual WHERE clause at run time? Would the unused parameters simply be ignored and cause no issues?

2. when you need to modify WHERE clause or WHERE parameters at runtime do you need to do so in an event handler? such as linqdatasource.selecting?
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.linqdatasource.selecting.aspx
I see from the above link it is possible, but is that the standard way to handle controlling filtering in code behind for linqdatasource?

2b. if you use an event such as linqdatasource.selecting to add where parameters and/or modify the where clause in code will that also break the builtin sorting and paging support of the linqdatasource with a gridview? 

For handy database interface, is it good to use SqldataSources exclusively intead of EntLib functions?

Thanks for any feedback.

I'm just discovering MVC with Visual 2010 using MS Training kit.

Can somebody explain me why we can always seefor the index view

<h2><%=ViewData["Message"] %></h2>

And the code generated by visual studio

<h2><%: ViewData["Message"] %></h2>

Is there any difference between %= and %: with any document on that

Hi guys,

Is there any problem to use MANUALLY, within a Javascript, the client ID code?

Like that  ctl00_ContentPlaceHolderConteudo_pgtoiframe

Explanation:

I have one iFrame that need to access div style located in the parent page. So I've done that using manually the clientID code. The code works perfectly and It's still working fine right now.

Will I get errors or problems in the future using it in that manner????

Thank you

Hello

I am new in visual studio 2010. I am wondering does visual studio 2010 provide a data insertion wizard? I do know that data can be edited using the grib view. Can anyone please recommend me a guide or a book teaching me how to use the build in code generation. By the way I am using it for web development with C#. 

Thank you
