CSLA4 and Razor WebGrid Help - (StackOverflowException)

drpuff posted on Wednesday, October 12, 2011

Hi,

Due to a major scope change, I've recently upgraded an existing project from CSLA3.8 + WPF to CSLA4 + MVC3 (razor). I should let you know at this point that I have much less experience with ASP.NET than WPF!

My issue is with trying to use the WebGrid with a 'ReadOnlyListBase' in ASP.NET - it always generates a StackOverflowException.

I can easily display the items in the ROLB, using the sytax shown by Rocky in the ASP.NET MVC ebook (i.e., using a 'foreach' loop), but it seems that using a WebGrid would be more compact (I'm planning on lazy-loading a 3-level BO hierarchy using Ajax).

Here's my code:

@model IEnumerable<AssetROInfo>
           
@{
    var assetGrid = new WebGrid(source: Model,
                                           defaultSort: "Code",
                                           rowsPerPage: 5,
                                           canPage: true, canSort: true
                                           );  
}

<h3>Asset List</h3>
 
            @assetGrid.GetHtml(
                tableStyle: "grid",
                headerStyle: "head",
                alternatingRowStyle: "alt",
                columns: assetGrid.Columns(
                    assetGrid.Column("Id", "ID"),
                    assetGrid.Column("Code", "Asset Code"),
                    assetGrid.Column("Description", "Asset Desc")    
                )
            )    

...and the StackOverflowException is happening on the

@assetGrid.GetHtml

call. I am unable to find any examples of using WebGrid with CSLA classes....am I missing something fundamental here?

It just seems like such a simple problem but I can't get to the cause of the problem. Would be grateful if anyone can help with this (or detail an appropriate approach).

Thanks,

John

[As this is my first post, I just have to say how impressed I've been with Csla since we started employing it 1.5yrs ago - Rocky, you've done a superb job...so thanks very much!]

I honestly haven't tried using the WebGrid component.

Can you post the full stack trace? Maybe there's a clue in there.

Or could you post a small sample project that fails so we could debug this in CSLA?

Hey I'm really sorry guys. You responded so quickly to my original post and I was rude and never came back to supply you with more information. Truth be told I had to leave what I was doing at the time and address some other pressing projects...I'll take a look at the initial problem and get back to you ASAP.

Sorry, John
