ef5.0 DBset

[Jun]

Hello.
Do you have a plan to support ef5.0 Dbset in reporting Q3 2013?
If so, when are you going to support it?


I don't want this link : http://blogs.telerik.com/careypayette/posts/13-07-30/try-out-new-entity-framework-support-in-telerik-reporting-and-earn-rewards and openacess.

Hello Jun,

DbSet is supported prior to Q3 2013, so you can actually use an older version if you need to. Please also note that Q3 2013 is now officially released. If you have any other issues please do not hesitate to ask.

Error : An error has occurred while processing Report 'Report1': An error occurred while invoking data retrieval method. Try restarting Visual Studio. ------------- InnerException ------------- A connection string has been provided but constructor with connection string argument could not be found. Either remove the connection string from the data source or provide a constructor which will use that connection string. For design time purposes a constructor that has a connection string argument and passes it to the base constructor is required.

It's Same Message.( q2 2013 Reporting )

Hi Jun,

By default the DbContext is created only with a single, parameterless constructor. As the exception message says you will have to either remove the connection string from the data source (you can just go in the designer.cs file, find the connection string and delete the whole line) or to provide a second constructor. For the latter to work you will have to create a constructor with a string argument and pass that string to the base constructor. For more information please check the first note in this help article.

Why does this happen on every EF setup?   Is there a way to automate this?   No matter what I do I cannot get rid of the error.

I deleted one line from designer.cs, the connectionstring line.   That didn't work.   Preview still gives this error.

Hi,

Add the constructor accepting string argument and try again to setup the data source component.

look for    
public YourEntities()
            : base("name=YourEntities")
        {
        }
Make an additional
public YourEntities(string connString)
            : base(connString)
        {
        }
