Thread: Datasource for an unrelated entity.

Datasource for an unrelated entity. Your last visit to this thread was on 1/1/1970 12:00:00 AM

Trying to do an option picker thing and running into problems.

I have a form that has a datasource on it that returns a 1:m for the current entity I'm on and have it tied to a datagrid. Now I want to place another datagrid next to it and have the datasource return all the records from a unrelated table. The idea is they are going to select the options from the unrelated grid and I'm going to go insert the records into my 1:m table\grid.

To do this I created a business rule on my unrelated table to return an IList of all the records. I then place a datasource on my form and used the GetByMethod to point to it. I then tied that datasource to my unrelated grid. When I go to open the form I get an error
'Non-static method requires a target.'

I also tried creating the business rule on the entity that I was on rather than my unrelated table and got the same results. I also tried messing with the IsCollection and UseSmartSelection with no joy. This happens whether it is a new record or I try to edit and existing one.

Not sure what it means yet but when I step through it in VS I can see it chokes when it tries to set the SourceObject The error is
'Non-static method requires a target.'
-----------------
void dsTemplate_OnCurrentEntitySet(object sender, EventArgs e)
{
dsTemplate.SourceObject = BindingSource.Current;
RegisterBindingsWithClient(dsTemplate);
}
-----------------

This is the business rule
-----------------
public static void GetOptions( ITemplateOptions templateoptions, out object result)
{
IRepository repository = EntityFactory.GetRepository();

IQueryable qry = (IQueryable)repository;
IExpressionFactory ef = qry.GetExpressionFactory();

ICriteria criteria = qry.CreateCriteria();
//Just a test to return some records. This will be modified later.
criteria.Add(ef.Eq("CreateUser", "ADMIN"));

result = criteria.List();

}
}

Nevermind

I moved the bussiness rule back up to my main entity and fixed my Typo (didnt show error while building though... wierd). And then it started working just as I though it should
