Hello Harry,

sounds great explication into your video.

Perhaps, I improving some bugs when I'm trying to rebuild my site after the importation of thoses 2 files (ASPxDynamicGrisView.cs, DynamicLinqServerModeDataSources.cs) into App_Code folder. Since I'm using VB as my language into my VisualStudio.... he really doesnt like your c# files compiling with the designer.vb's file. Do you have any alternative to help me please

Best Regards

Claude

First... Great work and great video.

I really want to use this on a current project. However, I'm having trouble getting this to work on my end.

Getting a compile error:

"The name 'DynamicDataManager1' does not exist in the current context"

I see it defined in the .ASPX file but it's like the code behind of the page template is having trouble resolving it.

Steps I've completed:

1. I've successfully built the "vanilla" Northwind Dynamic Data site using a LINQ to SQL data model (working).

2. I've copied the two new class files (ASPxDynamicGridView.cs & DynamicLinqServerModeDataSource.cs) into my "App_Code" directory.

3. I've copied the four custom 'PageTemplate' files into the DynamicData\PageTemplates folder.

4. Added references to the 5 needed DevEx assemblies and set their "Copy Local" attribute to true so they appear in the project BIN folder.

5. I've updated the Global.asax file as outlined in the video

I'm using v8.3 of DevExpress controls. Am I missing something? Anyone else seeing this same issue when following the video directions and beginning from scratch?

OK - After a good night's rest and taking another look @ the problem I've identified the difference that was causing me issues... ASP.NET Project Types.

The sample relies on using an ASP.NET “Web Site” project template while I was taking the more traditional “ASP.NET Web Application” solution/project template approach. I was able to use the ASP.NET “Web Site” approach to follow the instructions in the video exactly and everything worked perfectly on the first try.

Now, for several valid reasons I need to work with “ASP.NET Web Application” projects and not ASP.NET “Website” projects. The thing that was preventing me from moving forward with the sample was that “ASP.NET Web Application” projects require .ASPX pages to have not only a “.ASPX.CS” code-behind file but also a “.ASPX.DESIGNER.CS” file as well… “ASP.NET Website” projects do not have this added .DESIGNER.CS file requirement.

I’ve manually recreated the ‘DevExList’ control in a separate project and have gotten all the issues resolved up to the point of trying to get the ‘ASPxDynamicGridView’ control visible in the design file… which is where I’m getting stuck.

Could someone there @ DevExpress run through this scenario and see if they can get it working for ‘ASP.NET Web Application’ project types?

Hmmm... OK different issue. Does the 'ASPxDynamicGridView' control understand 'System.ComponentModel.DataAnnotations' markup? If not this is a dead-end for me.

i.e. - If I want to turn a column off using extended Metadata attributes? [ScaffoldColumn(false)] or define an alternate display name [DisplayName("Some Column Name Override")]

Jeremy,

We haven't tested Dynamic Data web apps much, mostly just the web sites. Web apps probably require different template pages. In general though, the markup should remain the same.

To make the ScaffoldColumn attribute work, replace the ASPxDynamicGridView.AddDataColumns method with this one

void AddDataColumns(MetaTable meta) {

   foreach(MetaColumn column in meta.Columns) {

       if(!column.Scaffold)

           continue;

       AddDataColumn(column);

   }

}

(column.Scaffold check added)

The DisplayName attribute functions properly.

Thanks.
