Question

Sometimes, I usually create a class with the type of data I want like this:

public class message{
    private string subject { get; set; }
    private string message { get; set; }
}

This way, I can bind a List<message> to a datagrid and change the DataPropertyName.

However, if I happen to add more auto properties to this class, my datagrid starts to misbehave and sometimes I don’t just want some of the properties to the datagrid. Is there anyway I can bind the datagrid to only the values I selected DataPropertyName for?

Thanks.

Answer 1

If you don’t want extra columns in your datagrid, why not start with your query, and don’t list them in the SELECT clause. This has the added benefit of reducing network traffic.

Create multiple queries or views off the same table and use the right one at the right timefor your need. This is the “upstream” solution.

Alternatively,

When the AutoGenerateColumns property is set to true, each column
automatically sets its DataPropertyName property to the name of a
property or database column in the data source specified by the
DataSource property. This binding can also be performed manually,
which is useful when you want to display only a subset of the
properties or database columns available in the data source. In such
cases, set the AutoGenerateColumns property to false, and then
manually add each DataGridViewColumn, setting the value of each
DataPropertyName property to the properties or database columns in the
data source that you want to display.

That is straight from MSDN, you should have researched a little more thoroughly before posting this.
