Question

I am having trouble binding some data from my MySQL database to a DataGridView in C# Windows Forms.

I have 2 tables, referenced by a foreign key in one table, and I want to do a JOIN between the 2 tables and bind that to my DataGridView. I have tried adding a new datasource from a DataSet, but that only allows to add 1 table in the datagridview (as far as I can tell).

Next I wanted to create a Entity Framework model and bind that to the DataGridView. I have created a new model named Model1, but the model is not accessible anywhere in my code. Is there something wrong with my logic?

I have also tried (after creating the model) to create a DataSource from an object (trying to select the model as the object, but it wasn’t visible in the wizard).

Or is there another way to bind a simple LEFT JOIN into a DataGridView?

Answer 1

Model1 is name of your EF Model not your context class,So in generated code by EF(Model1.Designer.cs), you must find a class that inherit from ObjectContext such as :

public partial class Entities : ObjectContext

and then:

new Entities().Table1....
