Custom column names for DataGridView with associated DataSource

Question

How can I setup custom column names for DataGridView with associated DataSource?

Here is some code:

class Key {     public string Value { get; }     public DateTime ExpirationDate { get; } }  List<Key> keys = new List<Key>(); ...// fill keys collection  DataGridView dataGridView = createAndInitializeDataGridView(); dataGridView.DataSource = keys; 

This gives me dataGridView with column names "Value" and "ExpirationDate". How should I proceed to change names to "Key" and "Expire" for example?

Answer 1

Use the DisplayName attribute on your properties to specify column names in your DataGridView:

class Key {     [System.ComponentModel.DisplayName("Key")]     public string Value { get; }     [System.ComponentModel.DisplayName("Expire")]     public DateTime ExpirationDate { get; } }  

Answer 2

You should be able to change the header cells after you've set the datasource:

    if (dataGridView1.Columns["Value"] != null)         dataGridView1.Columns["Value"].HeaderText = "Key";     if (dataGridView1.Columns["Expiration"] != null)         dataGridView1.Columns["Expiration"].HeaderText = "Expire";
