Cannot bind to the new display member in ComboBox

The accepted answer is not correct. The Op needed to change the order of how he was assigning DisplayMember, ValueMember and Datasource and then note the added line of code.

comboBox1.DisplayMember="Name";
comboBox1.ValueMember = "Id";
comboBox1.DataSource = lstItems;
comboBox1.BindingContext = this.BindingContext;

In my case, I did bind to properties that had the Browsable attribute set to false.

I.e. the error occurred because of:

[Browsable(false)]
public string MyProperty { get; set; }

And I did resolve it by simply removing the attribute:

public string MyProperty { get; set; }

You should make Name and Id properties. You can't bind ComboBox to fields.

public string Name { get; set; }
public int Id { get; set; }

It's also stated in docs:

ValueMember Property: Gets or sets the property to use as the actual value for the items in the System.Windows.Forms.ListControl.
