Bind class list in DataGridView

Question

I need to bind List<MyClass> myList to a DataGridView . And go to the result table with two column identifiers and a name.

Code snippets:

 private List<MyClass> myList = new List<MyClass>(){...}; public void BindClass() { dataGridView.DataSource = myList; } public MyClass { public MyDataClass Data{ get; set; } } public MyDataClass { public string ID { get; set; } public string Name { get; set; } } 

Is it possible?

Answer 1

How about binding to an anonymous type:

 public void BindClass() { dataGridView1.DataSource = myList.Select(myClass => new {myClass.Data.ID, myClass.Data.Name}).ToList(); } 

Will you update the data in a datagridview?

Answer 2

To do this, changing the model is extremely difficult (but possible), requiring an ICustomTypeDescriptor or TypeDescriptionProvider and a custom PropertyDescriptor . Honestly: not worth it.

Just add pass-thru properties:

 public MyClass { public MyDataClass Data{get; set;} [DisplayName("ID")] public string DataID { get {return Data.ID;} set {Data.ID = value;} } [DisplayName("Name")] public string DataName { get {return Data.Name;} set {Data.Name = value;} } } 

Answer 3

Easy with LINQ, as you can see in This answer

Here is a simple implementation of what I needed to attach to a datagridview.

  DataGridView1.DataSource = _ (From i In ItemList Select i.ListID, i.FullName, i.PurchaseDesc, i.EditSequence).ToList 

Answer 4

No, you cannot do this out of the box. You will need to write your own binding source (most likely with special logic for your specific purpose) to allow you to “drill” deeper than just one level of properties.
