C# DataGridViewComboBoxColumn binding problem

Question

Hey everyone! I suppose this is my first post on StackOverFlow.com :-)

I\'ve been having this problem for a while. To make it all simple, suppose we have 2 database tabl

Answer 1

This should work:

// create the column (probably better done by the designer)
DataGridViewComboBoxColumn categoryColumn = ...


// bind it
categoryColumn.DataSource = db.Categories.ToList();
categoryColumn.DisplayMember = "catName";  // display category.catName
categoryColumn.ValueMember = "id";         // use category.id as the identifier
categoryColumn.DataPropertyName = "catId"; // bind the column to book.catId

Answer 2

I managed to do it by overwriting the ToString() method in the concerned class. For you case, you could add in the definition of categories:

public override string ToString()
{
   return this.catName
}
